Glue potting machine in the application of electronic packaging: how to avoid air bubbles, overflow glue and other common problems?
In the field of electronic packaging, the glue potting process directly affects the sealing, insulation and long-term reliability of the product. However, problems such as bubbles, glue overflow, and uneven glue amount often trouble production engineers, resulting in reduced yield and even product failure. This article will deeply analyze the common problems of the glue potting process and provide solutions such as vacuum degassing, precise metering, and process optimization to help you improve the quality and efficiency of glue potting.
1.The key role of glue potting in electronic packaging
Potting refers to potting liquid glue (such as epoxy resin, silicone, polyurethane, etc.) into specific areas of electronic components or PCB boards to achieve waterproof, shockproof, insulation, heat dissipation and other functions. Typical applications include:
● Power module potting (such as new energy vehicle electronic control unit)
● LED drive circuit packaging (moisture-proof and corrosion-proof)
● Sensor protection (such as industrial-grade temperature and humidity sensor)
● PCB board overall glue potting (anti-vibration, dust-proof)
However, if the glue potting machine process is not properly controlled, it is easy to have problems such as bubble residue, glue overflow, and poor curing, which will affect product performance.

Automatic Adhesive Potting Machines SEC-S3030-C
2. Analysis of the four common problems and causes of glue potting process
1. Bubble problem (affecting sealing and insulation)
Reasons:
a. The glue itself contains air (especially high-viscosity glue)
b. The glue potting speed is too fast and the glue cannot flow fully
c. No vacuum degassing treatment
2. Glue overflow problem (affecting appearance and assembly)
Reasons:
a. Imprecise glue quantity control (too much or too little)
b. Unreasonable glue dispensing path planning
c. The glue is too fluid (low-viscosity glue is easy to spread)
3.Uneven glue quantity (resulting in insufficient local protection)
Reasons:
a. Insufficient metering accuracy of glue potting machine
b. Changes in glue viscosity (affected by temperature or storage conditions)
c. Blockage or wear of dispensing valve
4. Poor curing (affecting mechanical strength)
Reasons:
a. Wrong mixing ratio (two-component glue)
b. Curing temperature/time does not meet the standard
c. Glue is expired or damp
3. Solution: How to optimize the glue potting process?
1. Vacuum degassing technology (eliminating bubbles)
Method:
a. Vacuum degassing the glue before potting (vacuum pump evacuates for 5-10 minutes)
b. Use dynamic degassing system (degassing while potting)
Applicable scenarios: high viscosity glue (such as epoxy resin)
Accurate metering control (avoiding glue overflow/glue shortage)
Method:
a. Select a high-precision metering pump (gear pump or screw pump)
b. Use a closed-loop control system (real-time monitoring of glue volume and feedback adjustment)
C. Optimize the dispensing path (avoid overlap or glue leakage)

Important Tips to Consider When Installing Epoxy Mixing Nozzles
Epoxy is an incredibly versatile adhesive with numerous applications, from carpentry and woodworking to metal equipment.Butit’s also quite unstable, and incorrectly mixing resins can lead to major problems.Because of this, you will need the properepoxy mixing nozzleto complete your project!
Here is everything you need to know about epoxy glue and how to use it:
Epoxy has two parts: resin and hardener. It’s essential to mix them only once you’re ready for gluing, as its pot life only lasts for a few hours at most. In addition, you’ll need to be accurate with the ratios as much as possible; otherwise, it could cause a hot spot and lead to cracking.
Types of epoxy mixing nozzles
Static mixers do not contain moving components and blend liquid materials using flow current. They are primarily used for two-component rubber cylinders and dispensing machines, but they have many other applications.
These mixers are the most affordable and need little maintenance.However, they also require more manual labor. Their tubes can be divided as follows: bayonet type, bayonet mount type, round mouth, and self-threaded.
Dynamic mixers blend liquid components with a rotatingmotor. As a result, they are more efficient and consistent, better used for sensitive liquids.These mixers are primarily used for electronic production, electrical manufacturing, automotive manufacturing, and more.
Tips for mixing your resins properly with an epoxy mixing nozzle
Measure your resins and hardeners accurately with a digital scale or mixing cup. Generally, a 2:1 resin-to-hardener ratio is recommended.
Mix the solution for two to three minutes or until it is thoroughly blended
Avoid applying epoxy resins in cold temperatures or high humidity
Use high-quality epoxy mixing nozzles from trusted suppliers
Make sure to start pouring the mixture immediately, especially in larger quantities
Choosing your mixer
Ultimately, your choice of mixer and mixing nozzle will depend on your needs. For example, static mixers may be the best option if  using multiple adhesives. This is because they require no energy to operate, and the nozzle can be changed according to your desired rate.
For static mixing nozzles, make sure to consider their shot size and shot frequency.

Types and Features of Dispensing Nozzles
Introduction
Dispensing nozzles are cylindrical spout present at the end of a pipe, tube or tube which is used to control the ejaculation of gas or liquid. This is a device used to accelerate the flow from the entrance of the nozzle until the tip of the converging section. (Diesel Exhaust Fluid) DEF nozzles are good for gas station pumps and they are different from the nozzles which dispense other fluids like gas or compressed natural gas (CNG). Any gas station owners and operators need to understand the right type of DEF nozzles to be used at their station to dispense the fluid. If you put diesel into a DEF cart, it will float on the DEF as diesel is less dense than DEF. There are various types of nozzles available in the market with its characteristics. In this article, we are trying to cover some of them along with their specific features.
Type S Nozzle
It is bundled with high quality and durable stainless steel needle. This type of nozzle accepts only 12 needle sizes ranging from 25G to 11G which helps accommodate dispensing of even very less amount of low viscosity liquids. This type of nozzle can be applicable to devices like syringes, micro plunger pumps, screw pumps, etc.
Type L Nozzle
This type of needles also bundled with high quality and durable stainless steel needle. This type of nozzle accepts only 6 needle sizes ranging from 14G to 7G which helps accommodate dispensing of even very high amount of high viscosity liquids. This type of nozzle can be applicable on devices like screw pumps, KAPPA 5 MD, etc.
Syringe Nozzle
This is an economical and cheap nozzle that comes with stainless steel needle bonded to polyethylene boss with epoxy resin and is customized for syringe applications. These are applicable for dispensing small and very small amounts of liquids.
12.7 L Syringe Nozzle
Such a type of nozzle features four-winged and double threaded boss to ensure a tight connection with the syringe. These kinds of nozzles are useful for dispensing small and very small amounts of liquids.
Flexible Nozzle
This nozzle is ideal for anaerobic liquids. It prevents anaerobic liquids from within and allows dispensing in narrow spaces without doing any damages to the product. These are designed especially for liquid discharging valves and syringe-type dispensers for anaerobic liquids.
Taper Nozzle
A tapered tube present in such kind of nozzle ensures a smoother flow of liquid. These are ideal for dispensing medium and high viscosity liquids. These kinds of nozzles are useful for dispensing small and very small amounts of liquids.
Precision Taper Nozzle
This precisely crafted one-piece molded nozzle ensures accurate dispensing of the very small amount of liquids. The tapper tube present inside the nozzle helps smooth liquid flow and the double thread feature ensures a tight connection. These kinds of nozzles are also useful for dispensing small and very small amounts of liquids.                
Quarter Inch Poly Nozzle
These are one-piece molded polyethylene nozzles with tapper threaded connectors for the quarter-inch pipe. The tapered tube present inside the nozzle helps reducing resistance and facilitates high liquid flow.
Resin Nozzle
These are specially designed for sophisticated liquid discharging valves used in the DEF nozzle assembly. It is a polyethylene nozzle for anaerobic liquids and ultraviolet curing liquids.
Multi-Dispensing Nozzle
Multi dispensing nozzles are designed to meet product design requirements and work for the betterment of the same multi-purposely. These types of nozzles are generally applicable to automatic machines, robotic dispensers, etc.
Conclusion
With the details of few aforesaid nozzles, you will be now able to understand their types and features and can now better opt the one which suits your needs. DEF nozzles are useful for manufacturers of diesel exhaust fluid and require a suitable container to cover it. The DEF nozzle makes the pumping of fluid easier and also adds to its convenient use. With ever-growing diesel vehicles on the road and an evolving number of DEF applications, the concern for quality and reliable equipment comes into play. When it comes to dispensing DEF and diesel fuel, the Empire Lube Equipment range of nozzles options cater to the exact dispensing needs of customers.

LED patch glue and Dijiao basic knowledge you know how much?
China LED network   2017 August 25 15:52  
1, the role of patch adhesive surface adhesive (SMA, surfacemountadhesives) for wave soldering and reflow soldering, mainly used to fixed components on the printed circuit board, the general use of dispensing or stencil printing method to distribution, to Maintain the position of the component on the printed circuit board (PCB) to ensure that the components are not lost during transmission on the assembly line. Paste the components into the oven or reflow machine after heating hardening. It is not the same with the so-calhgf solder paste, once heated and hardened, and then heating will not melt, that is, the hot film curing process is irreversible. The effect of the SMT patch will vary depending on the heat curing conditions, the connectors, the equipment used, and the operating environment. When used in accordance with the production process to choose patch glue.
2, the composition of patch plastic PCB assembly used in most of the surface patch adhesive (SMA) are epoxy (epoxies), although there are acrylic (acrylics) for special purposes. In the introduction of high-speed Dijiao system and the electronics industry to master how to deal with relatively short shelf life of the product, the epoxy resin has become the world's more mainstream glue technology. Epoxy resins generally provide good adhesion to a wide range of circuit boards and have very good electrical properties. The main ingredients are: base material (ie, the main polymer materials), fillers, curing agents, and other additives.
3, the use of patch glue purpose a. Wave soldering to prevent component off (wave soldering process) b. Reflow to prevent the other side of the components off (double-sided reflow process) c. To prevent component displacement and legislation (Re-coating process, pre-coating process) d. For marking (wave soldering, reflow, pre-coating), printed circuit boards and components to change the volume, with a patch for the mark.
4, the use of patch glue classification a. Dispensing type: through the dispensing equipment in the printed circuit board sizing. b. Scraping type: sizing by stencil or copper screen printing.
5, Dijiao method SMA can be used syringe Dijiao, needle transfer method or template printing method applied to the PCB. The use of the needle transfer method is less than 10% of the total application, and it is used to place the array of needles in a tray of glue. And then hang the drops as a whole to the plate. These systems require a lower tacky glue and have a good resistance to moisture absorption because it is exposed to the indoor environment. Key factors in the control of needle transfer diets include needle diameter and pattern, the temperature of the gel, the depth of the needle immersion, and the length of the duration of the dispenser (including the delay time before and during contact of the needle). The tank temperature should be between 25 and 30 ° C, which controls the viscosity and the number and form of glue.
Template printing is widely used in solder paste, also available with the distribution of glue. Although less than 2% of the SMA is currently printed with the template, but the interest in this method has increased, the new equipment is to overcome some of the earlier limitations. The correct template parameter is the key to achieving good results. For example, contact printing (zero plate height) may require a delay period, allowing good glue to form. In addition, non-contact printing (approximately 1 mm gap) for polymer templates requires optimum scraper speed and pressure. The thickness of the metal template is generally 0.15 to 2.00 mm and should be slightly larger than (+0.05 mm) between the component and the PCB.
The final temperature will affect the viscosity and the shape of the dot, and most modern dispensers rely on the temperature control device on the mouth of the mouth or the chamber to keep the gel temperature higher than room temperature. However, if the PCB temperature from the front of the process to be improved, the dot pattern may be damaged.

It has high flowrate, long service life and chemistry stability. The advantage of this cartridge is that it can be washed with brush when the cartridge is dirty.
  Negative Potential Antioxidant Filter 
remove the excessive free radicalsIt’s able to take effective prevention and combating against senile plaques, Parkinson’s, cataracts, arterial sclerosis, cerebral apoplexy, malignant change of cell, etc. caused by the free radicals.
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions. When the chain reaction occurs in a cell, it can cause damage or death to the cell. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid, or polyphenols.
  Hollow Fiber Ultrafiltration Membrane
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients leads to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate. This separation process is used in industry and research for purifying and concentrating macromolecular (103 – 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from microfiltration. Both of these separate based on size exclusion or particle capture. It is fundamentally different from membrane gas separation, which separate based on different amounts of absorption and different rates of diffusion. Ultrafiltration membranes are defined by the Molecular Weight Cut Off (MWCO) of the membrane used. Ultrafiltration is applied in cross-flow or dead-end mode.

   About Water Purifier
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal of this process is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain. The standards for drinking water quality are typically set by governments or by international standards. These standards will typically set minimum and maximum concentrations of contaminants for the use that is to be made of the water. It is not possible to tell whether water is of an appropriate quality by visual examination. Simple procedures such as boiling or the use of a household activated carbon filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source. Even natural spring water – considered safe for all practical purposes in the 19th century – must now be tested before determining what kind of treatment, if any, is needed. Chemical and microbiological analysis, while expensive, are the only way to obtain the information necessary for deciding on the appropriate method of purification. According to a 2007 World Health Organization report, 1.1 billion people lack access to an improved drinking water supply, 88 percent of the 4 billion annual cases of diarrheal disease are attributed to unsafe water and inadequate sanitation and hygiene, and 1.8 million people die from diarrheal diseases each year. The WHO estimates that 94 percent of these diarrheal cases are preventable through modifications to the environment, including access to safe water.Simple techniques for treating water at home, such as chlorination, filters, and solar disinfection, and storing it in safe containers could save a huge number of lives each year. Reducing deaths from waterborne diseases is a major public health goal in developing countries.
Membrane filtration
Membrane filters are widely used for filtering both drinking water and sewage. For drinking water, membrane filters can remove virtually all particles larger than 0.2 um—including giardia and cryptosporidium. Membrane filters are an effective form of tertiary treatment when it is desired to reuse the water for industry, for limited domestic purposes, or before discharging the water into a river that is used by towns further downstream. They are widely used in industry, particularly for beverage preparation (including bottled water). However no filtration can remove substances that are actually dissolved in the water such as phosphorus, nitrates and heavy metal ions.
Removal of ions and other dissolved substances
Ultrafiltration membranes use polymer membranes with chemically formed microscopic pores that can be used to filter out dissolved substances avoiding the use of coagulants. The type of membrane media determines how much pressure is needed to drive the water through and what sizes of micro-organisms can be filtered out.
Ion exchange:Ion exchange systems use ion exchange resin- or zeolite-packed columns to replace unwanted ions. The most common case is water softening consisting of removal of Ca2+ and Mg2+ ions replacing them with benign (soap friendly) Na+ or K+ ions. Ion exchange resins are also used to remove toxic ions such as nitrite, lead, mercury, arsenic and many others.
Precipitative softening:13.12–13.58 Water rich in hardness (calcium and magnesium ions) is treated with lime (calcium oxide) and/or soda-ash (sodium carbonate) to precipitate calcium carbonate out of solution utilizing the common-ion effect.
Electrodeionization: Water is passed between a positive electrode and a negative electrode. Ion exchange membranes allow only positive ions to migrate from the treated water toward the negative electrode and only negative ions toward the positive electrode. High purity deionized water is produced with a little worse degree of purification in comparison with ion exchange treatment. Complete removal of ions from water is regarded as electrodialysis. The water is often pre-treated with a reverse osmosis unit to remove non-ionic organic contaminants.
Ozone disinfection Ozone is an unstable molecule which readily gives up one atom of oxygen providing a powerful oxidizing agent which is toxic to most waterborne organisms. It is a very strong, broad spectrum disinfectant that is widely used in Europe. It is an effective method to inactivate harmful protozoa that form cysts. It also works well against almost all other pathogens. Ozone is made by passing oxygen through ultraviolet light or a “cold” electrical discharge. To use ozone as a disinfectant, it must be created on-site and added to the water by bubble contact. Some of the advantages of ozone include the production of fewer dangerous by-products and the absence of taste and odour problems (in comparison to chlorination) . Although fewer by-products are formed by ozonation, it has been discovered that ozone reacts with bromide ions in water to produce concentrations of the suspected carcinogen bromate. Bromide can be found in fresh water supplies in sufficient concentrations to produce (after ozonation) more than 10 parts per billion (ppb) of bromate — the maximum contaminant level established by the USEPA. Another advantage of ozone is that it leaves no residual disinfectant in the water. Ozone has been used in drinking water plants since 1906 where the first industrial ozonation plant was built in Nice, France. The U.S. Food and Drug Administration has accepted ozone as being safe; and it is applied as an anti-microbiological agent for the treatment, storage, and processing of foods. Ultraviolet disinfection Ultraviolet light (UV) is very effective at inactivating cysts, in low turbidity water. UV light’s disinfection effectiveness decreases as turbidity increases, a result of the absorption, scattering, and shadowing caused by the suspended solids. The main disadvantage to the use of UV radiation is that, like ozone treatment, it leaves no residual disinfectant in the water; therefore, it is sometimes necessary to add a residual disinfectant after the primary disinfection process. This is often done through the addition of chloramines, discussed above as a primary disinfectant. When used in this manner, chloramines provide an effective residual disinfectant with very few of the negative effects of chlorination.
Distillation removes all minerals from water, and the membrane methods of reverse osmosis and nanofiltration remove most to all minerals. This results in demineralized water which is not considered ideal drinking water. The World Health Organization has investigated the health effects of demineralized water since 1980.Experiments in humans found that demineralized water increased diuresis and the elimination of electrolytes, with decreased blood serum potassium concentration. Magnesium, calcium, and other minerals in water can help to protect against nutritional deficiency. Demineralized water may also increase the risk from toxic metals because it more readily leaches materials from piping like lead and cadmium, which is prevented by dissolved minerals such as calcium and magnesium. Low-mineral water has been implicated in specific cases of lead poisoning in infants, when lead from pipes leached at especially high rates into the water. Recommendations for magnesium have been put at a minimum of 10 mg/L with 20–30 mg/L optimum; for calcium a 20 mg/L minimum and a 40–80 mg/L optimum, and a total water hardness (adding magnesium and calcium) of 2 to 4 mmol/L. At water hardness above 5 mmol/L, higher incidence of gallstones, kidney stones, urinary stones, arthrosis, and arthropathies have been observed.[45] Additionally, desalination processes can increase the risk of bacterial contamination.
Other popular methods for purifying water, especially for local private supplies are listed below. In some countries some of these methods are also used for large scale municipal supplies. Particularly important are distillation (de-salination of seawater) and reverse osmosis.
Boiling: Bringing it to its boiling point at 100 °C (212 °F), is the oldest and most effective way since it eliminates most microbes causing intestine related diseases, but it cannot remove chemical toxins or impurities.[38] For human health, complete sterilization of water is not required, since the heat resistant microbes are not intestine affecting.[37] The traditional advice of boiling water for ten minutes is mainly for additional safety, since microbes start getting eliminated at temperatures greater than 60 °C (140 °F). Though the boiling point decreases with increasing altitude, it is not enough to affect the disinfecting process. In areas where the water is “hard” (that is, containing significant dissolved calcium salts), boiling decomposes the bicarbonate ions, resulting in partial precipitation as calcium carbonate. This is the “fur” that builds up on kettle elements, etc., in hard water areas. With the exception of calcium, boiling does not remove solutes of higher boiling point than water and in fact increases their concentration (due to some water being lost as vapour). Boiling does not leave a residual disinfectant in the water. Therefore, water that is boiled and then stored for any length of time may acquire new pathogens. Granular Activated Carbon filtering: a form of activated carbon with a high surface area, adsorbs many compounds including many toxic compounds. Water passing through activated carbon is commonly used in municipal regions with organic contamination, taste or odors. Many household water filters and fish tanks use activated carbon filters to further purify the water. Household filters for drinking water sometimes contain silver as metallic silver nanoparticle. If water is held in the carbon block for longer period, microorganisms can grow inside which results in fouling and contamination. Silver nanoparticles are excellent anti-bacterial material and they can decompose toxic halo-organic compounds such as pesticides into non-toxic organic products. Distillation involves boiling the water to produce water vapour. The vapour contacts a cool surface where it condenses as a liquid. Because the solutes are not normally vaporised, they remain in the boiling solution. Even distillation does not completely purify water, because of contaminants with similar boiling points and droplets of unvapourised liquid carried with the steam. However, 99.9% pure water can be obtained by distillation. Reverse osmosis: Mechanical pressure is applied to an impure solution to force pure water through a semi-permeable membrane. Reverse osmosis is theoretically the most thorough method of large scale water purification available, although perfect semi-permeable membranes are difficult to create. Unless membranes are well-maintained, algae and other life forms can colonize the membranes. The use of iron in removing arsenic from water. See Arsenic contamination of groundwater. Direct contact membrane distillation (DCMD). Applicable to desalination. Heated seawater is passed along the surface of a hydrophobic polymer membrane. Evaporated water passes from the hot side through pores in the membrane into a stream of cold pure water on the other side. The difference in vapour pressure between the hot and cold side helps to push water molecules through. Desalination – is a process by which saline water (generally sea water) is converted to fresh water. The most common desalination processes are distillation and reverse osmosis. Desalination is currently expensive compared to most alternative sources of water, and only a very small fraction of total human use is satisfied by desalination. It is only economically practical for high-valued uses (such as household and industrial uses) in arid areas. Gas hydrate crystals centrifuge method. If carbon dioxide or other low molecular weight gas is mixed with contaminated water at high pressure and low temperature, gas hydrate crystals will form exothermically. Separation of the crystalline hydrate may be performed by centrifuge or sedimentation and decanting. Water can be released from the hydrate crystals by heating In Situ Chemical Oxidation, a form of advanced oxidation processes and advanced oxidation technology, is an environmental remediation technique used for soil and/or groundwater remediation to reduce the concentrations of targeted environmental contaminants to acceptable levels. ISCO is accomplished by injecting or otherwise introducing strong chemical oxidizers directly into the contaminated medium (soil or groundwater) to destroy chemical contaminants in place. It can be used to remediate a variety of organic compounds, including some that are resistant to natural degradation

Highly crosslinked cation ion exchange resin filter is a premium high purity grade of conventional gel poly(styrene sulfonate) cation-exchange resin. Its chemical and physical stability, particularly its resistance to oxidation and very low extractables content plays a large part in its successful employment in demineralization of water. The size grading ensures trouble free operation in both standard coflow and counterflow operation. The higher density spheres of the graded cation resin ensures good backwash separation at the recommended flow rates. The low percentage swelling on conversion from exhausted to regenerated form allows the resin bed to be free of compacted areas when reintroduced to service in the exhaustion cycle. This ensures low pressure drop during service. Water softening strong acid cation polystyrene resin is available in a number of grades specially designed for different applications.
  Natural Mineral Stone Filter 
Maifan Stone, also known as “bakuhanseki” is a special mineral rock used in Chinese medicine to treat various skin diseases. It is composed of minerals including but not limited to plagioclase feldspar, orthoclase feldspar, hornblende, and biotite (all four mentioned before are silicate minerals). Maifan Stone contains plenty of micro-nutrient elements, such as calcium, iron, zinc, magnesium, copper, and selenium, all essential to a healthy human body. As a Chinese medicine, it is especially useful in treating skin tumors and ulcers. In addition to that, many mineral water manufacturers in China dissolve a small amount of Maifan Stone during the preparation of their product, meant to enhance the micro-nutrient density in the water. In ordinary cooking, both rice and tea, while being washed, may be dipped with Maifan Stone to increase their effects on health. Maifan stone has been used as a water filtration and conditioning media for shower and bath filters.

  Negative Potential Antioxidant Filter 
remove the excessive free radicalsIt’s able to take effective prevention and combating against senile plaques, Parkinson’s, cataracts, arterial sclerosis, cerebral apoplexy, malignant change of cell, etc. caused by the free radicals.
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions. When the chain reaction occurs in a cell, it can cause damage or death to the cell. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid, or polyphenols.
  Hollow Fiber Ultrafiltration Membrane
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients leads to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate. This separation process is used in industry and research for purifying and concentrating macromolecular (103 – 106 Da) solutions, especially protein solutions. Ultrafiltration is not fundamentally different from microfiltration. Both of these separate based on size exclusion or particle capture. It is fundamentally different from membrane gas separation, which separate based on different amounts of absorption and different rates of diffusion. Ultrafiltration membranes are defined by the Molecular Weight Cut Off (MWCO) of the membrane used. Ultrafiltration is applied in cross-flow or dead-end mode.

   About Water Purifier
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water. The goal of this process is to produce water fit for a specific purpose. Most water is disinfected for human consumption (drinking water) but water purification may also be designed for a variety of other purposes, including meeting the requirements of medical, pharmacological, chemical and industrial applications. In general the methods used include physical processes such as filtration, sedimentation, and distillation, biological processes such as slow sand filters or biologically active carbon, chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light. The purification process of water may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, fungi; and a range of dissolved and particulate material derived from the surfaces that water may have made contact with after falling as rain. The standards for drinking water quality are typically set by governments or by international standards. These standards will typically set minimum and maximum concentrations of contaminants for the use that is to be made of the water. It is not possible to tell whether water is of an appropriate quality by visual examination. Simple procedures such as boiling or the use of a household activated carbon filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source. Even natural spring water – considered safe for all practical purposes in the 19th century – must now be tested before determining what kind of treatment, if any, is needed. Chemical and microbiological analysis, while expensive, are the only way to obtain the information necessary for deciding on the appropriate method of purification. According to a 2007 World Health Organization report, 1.1 billion people lack access to an improved drinking water supply, 88 percent of the 4 billion annual cases of diarrheal disease are attributed to unsafe water and inadequate sanitation and hygiene, and 1.8 million people die from diarrheal diseases each year. The WHO estimates that 94 percent of these diarrheal cases are preventable through modifications to the environment, including access to safe water.Simple techniques for treating water at home, such as chlorination, filters, and solar disinfection, and storing it in safe containers could save a huge number of lives each year. Reducing deaths from waterborne diseases is a major public health goal in developing countries.
Membrane filtration
Membrane filters are widely used for filtering both drinking water and sewage. For drinking water, membrane filters can remove virtually all particles larger than 0.2 um—including giardia and cryptosporidium. Membrane filters are an effective form of tertiary treatment when it is desired to reuse the water for industry, for limited domestic purposes, or before discharging the water into a river that is used by towns further downstream. They are widely used in industry, particularly for beverage preparation (including bottled water). However no filtration can remove substances that are actually dissolved in the water such as phosphorus, nitrates and heavy metal ions.
Removal of ions and other dissolved substances
Ultrafiltration membranes use polymer membranes with chemically formed microscopic pores that can be used to filter out dissolved substances avoiding the use of coagulants. The type of membrane media determines how much pressure is needed to drive the water through and what sizes of micro-organisms can be filtered out.
Ion exchange:Ion exchange systems use ion exchange resin- or zeolite-packed columns to replace unwanted ions. The most common case is water softening consisting of removal of Ca2+ and Mg2+ ions replacing them with benign (soap friendly) Na+ or K+ ions. Ion exchange resins are also used to remove toxic ions such as nitrite, lead, mercury, arsenic and many others.
