Jacketed Reactor And Pipe Coil Reactor | JCT Machinery

Jacketed Reactor

The outer wall is provided with a jacket, in which a heating or cooling medium (such as steam, hot or cooling water, etc.) flows. The heating or cooling medium exchanges heat with the reaction materials through the jacket, thereby achieving temperature control.

Pipe Coil Reactor

Pipe coils (usually spiral or annular pipes) can be installed inside and outside, and the heating or cooling medium circulates through the coils, and heating or cooling is achieved through heat exchange between the coils and the reaction materials.

1. Heat Exchange Efficiency

Jacketed Reactor: The heat exchange efficiency of jacketed reactor is relatively low, because the heat needs to be transferred to the reaction material through the jacket wall, and the heat transfer rate of this process is slow.

Pipe Coil Reactor: The heat exchange efficiency of pipe coil reactor is high, because the contact area between the coil and the reaction material is large, and the heat can be transferred to the reaction material more quickly, which is particularly suitable for processes that require rapid heating or cooling.

2. Applicable Materials

Jacketed Reactor: Applicable to various viscosity materials, especially when processing high viscosity and high density materials. The jacket design can ensure uniform heating or cooling during the reaction process.

Pipe Coil Reactor: It is more suitable for materials with low or medium viscosity. When processing high viscosity materials, the coil may encounter resistance, resulting in unsatisfactory heating or cooling effects.

3. Applicable Scenarios

Jacketed Reactor: Commonly used in large-scale production, high-viscosity materials or chemical reaction processes that require a long reaction time, suitable for long-term and stable reaction operations. Suitable fo reaction processes that require more precise temperature control, such as the synthesis of unsaturated resins and polyester resins.

Pipe Coil Reactor: Commonly used in small-scale or medium-sized production, especially reaction processes that require rapid temperature control, such as certain polymerization reactions, catalytic reactions, etc. Suitable for applications with rapid heating or cooling.

4. Equipment Footprint and Space Requirement

Jacketed Reactor: Due to the external structure of jacket, jacketed reactor is larger in size and occupies more space, especially when large-scale production is required, a larger footprint may be required.

Pipe Coil Reactor: The design of pipe coil reactor is usually more compact and occupies relatively less space, which is suitable for use in environments with relatively small spaces.

The production of epoxy resin usually involves the chemical reaction of epoxy compounds (such as epichlorohydrin) and curing agents to form high molecular polymers. The design of reactor should take into account the reaction temperature, pressure, stirring speed and other parameters to ensure that the reaction is complete and uniform.

Feature: Reactor is usually a jacketed reactor, and the reaction temperature can be adjusted by the jacket temperature control system. Reactor is equipped with an agitator to ensure uniform mixing of raw materials and promote the reaction.

3. Vacuum Degassing System

Function: During the production of epocy resin, some raw materials may produce bubbles or impurities, which will affect the quality of the final product. Vacuum degassing system extracts the gas in reactor to remove these unnecessary gases, ensure the stability of the reaction process and improve the quality of the product.

Equipment: Vacuum pump, vacuum box, etc.

4. Cooling System

Function: The heat generated during the reaction process may cause the temperature to be too high, so reactor needs to be equipped with a cooling system to keep the reaction temperature within a controllable range. The common cooling method is jacket cooling, which reduces the temperature by flowing water or coolant in the outer jacket of reactor.

Equipment: Cooling tower, cooling water circulation system, etc.

Epoxy Resin Production Process

The production process flow of epocy resin usually includes raw material preparation (epoxy compound and curing agent, etc.), mixing reaction (carried out in reactor), cooling and degassing, filtering impurities, final molding and packaging, etc. The whole process requires strict control of reaction conditions, such as temperature, time, stirring speed and curing agent addition, to ensure product quality.

Features and Advantages of Epoxy Resin Production Line

High Degree of Automation: Epoxy resin production line usually adopt automated control, which can improve production efficiency and product consistency while reducing labor costs.

High-precision Control: During the reaction process, key parameters such as temperature, time, pressure, stirring speed, etc. are precisely controlled to ensure stable product quality.

Environmental Protection and Safety: Epoxy resin production line should meet environmental protection requirements, reduce harmful gas emissions, and the equipment design should have high safety performance to avoid dangers during the reaction process.

Different Types Of Silicone Sealant | JCT Machinery

Recently, a group of foreign customers came to JCT's factory to learn how to make silicone sealant, and saw how high quality the JCT 5L double planetary mixer is! We made neutral silicone sealant and acidic silicone sealant.

Many customers have asked JCT: which silicone sealant is better sold? Different silicone sealants have different application scenarios, and the performance characteristics of silicone sealant are also different.

Comparison of Silicone Sealants

1. Curing Mechanism

Neutral Silicone Sealant: Its curing process is triggered by a neutral catalyst. This type of sealant does not release any acidic substances during the curing process, so it has no sour smell. The reaction of neutral silicone sealant is usually promoted by moisture or humidity.

Acidic Silicone Sealant: Its curing process is caused by the catalytic reaction of an acidic catalyst. During the curing process, acidic silicone sealant releases a small amount of acetic acid, so it has a distinct sour smell.

2. Scope of Application

Neutral Silicone Sealant: Because it does not release acidic substances, it is suitable for a wider range of materials, including stone, aluminum alloy, mirror, plastic, wood, etc. This makes neutral silicone sealant more widely used in fields such as construction, automobiles, electronics and glass curtain walls.

Acidic Silicone Sealant: It is mainly used for bonding non-porous materials such as metal, glass and ceramics. Due to the release of acetic acid, acidic silicone sealant is not suitable for certain acid-sensitive materials, such as aluminum, copper, galvanized steel and other metals, especially in automobiles, construction and electronic products.

3. Curing Speed

Neutral Silicone Sealant: The curing speed is relatively slow, especially in low humidity environments, but its advantage is that it can be constructed in more demanding environments.

Acidic Silicone Sealant: Usually cures faster, suitable for fast construction and sealing work in a short time.

4. Weather Resistance and Durability

Neutral Silicone Sealant: Neutral silicone sealant usually has better weather resistance, aging resistance and UV resistance, and is particularly suitable for applications exposed outdoors for a long time.

Acidic Silicone Sealant: Acidic silicone sealant usually has good weather resistance, but its applicable temperature range and durability are slightly worse than neutral silicone sealant.

5. Environmental Adaptability

Neutral Silicone Sealant: Because it does not release harmful gases, it is suitable for use in applications with high corrosive requirements, especially for electronic equipment, glass decoration and other precision engineering materials.

Acidic Silicone Sealant: Because it releases acetic acid, it is not suitable for sealing  materials that require non-corrosive or acid-sensitive.
