9201A/B Epoxy Resin Helps the Development of Wind Power Industry

Epoxy resin is widely used in wind power, electronic and electrical, chemical anti-corrosion, aerospace, rail transportation, machinery manufacturing, ship transportation and other fields due to its strong adhesion, good corrosion resistance, strong electrical insulation and high mechanical properties.

The series of epoxy resin products for wind turbine blades mainly include vacuum infusion resin, hand lay-up resin and mold resin, etc., which have the characteristics of good mechanical properties, fatigue resistance, high and low temperature resistance, excellent mechanical properties, rapid prototyping, and typhoon resistance.

YQXPOLYMER 9201A/B epoxy resin is a product developed to meet the development needs of "lightweight" and "large-scale" wind turbine blades. YQXPOLYMER 9201A/B is an epoxy resin curing agent system specially designed for megawatt wind turbine blades, and it has long operating time and excellent mechanical strength and DNV certified. 

Epoxy resin has excellent mechanical properties, chemical stability and corrosion resistance, and can be used as blade structural parts, connectors and coatings for wind power generation. In the supporting structure, skeleton and connectors of the blade, epoxy resin can provide high strength, high stiffness and fatigue resistance to ensure the stability and reliability of the blade. In addition, epoxy resin can also improve the wind shear resistance and impact resistance of the blades, reduce the vibration noise of the blades, and improve wind power generation efficiency.

The application of epoxy resin in wind turbine blade coating is also very critical. By coating epoxy resin on the blade surface, the wear resistance and UV resistance of the blade can be improved, and the service life of the blade can be extended. At the same time, it can also reduce the weight and resistance of the blades and improve the efficiency of wind power generation.

Epoxy resin needs to be used in many aspects of the wind power industry, with a wide range of applications. Currently, among the blade materials for wind power generation, epoxy resin is mainly used in wind turbine blades, the core component of the front end of wind turbines. It is used to make the main beams, shells, webs, blade molds and blade trailing edge bonding.

Due to the development needs of "lightweight" and "large-scale" wind turbine blades, the material properties of epoxy resin can optimize the basic parameters such as strength, stiffness and dynamic fatigue of wind turbine blades, making the wind turbine blades lighter, with longer service life, better maintenance performance and shorter maintenance cycle.

The epoxy resin curing agent contributes particularly crucially to the performance of the wind turbine blade system. Only curing agents with good structural properties can effectively enhance the overall strength of the epoxy resin and thereby enhance the blade strength. In addition, curing agents also have an important impact on process control of blade manufacturing. If the viscosity of the curing agent is too high, it will be difficult to operate. If the reaction speed is too fast, the opening time will be too short. During the curing process of the blade, the reaction will be exothermic and smoke will be emitted, posing risks to the operation. YQXPOLYMER 9201A/B has low mixing viscosity, excellent fiber wettability, long gel time and operable time, low exothermic peak, and excellent comprehensive mechanical properties after curing.

a share since there’s still popular belief that wind turbines are the antichrist and the absolute worst thing we could do to birds…

[rjzimmerman]

Excerpt from this story from The Columbian:

A simple coat of black paint on the white blade of a wind turbine could save countless birds from flying into the machines and to their deaths each year.

It’s working in Norway, and now researchers from Oregon State University are trying it in the West. With $400,000 allocated by the state Legislature, Christian Hagen, an associate professor in the university’s Department of Fisheries, Wildlife and Conservation Sciences, is leading a team that’s painting turbines at a PacifiCorp wind farm in Wyoming. A doctoral student and officials with the  U.S. Geological Survey, U.S. Fish and Wildlife Service and U.S. Department of Energy are collaborating on the project.

Studies show that wind turbines kill anywhere from 140,000 to nearly half a million birds each year, in addition to the hundreds of millions killed each year by flying into buildings or by house cats.

A study from Norwegian researchers published in 2020 in the journal Ecology and Evolution found painting one of the three blades of a wind turbine black reduced bird mortality by more than 70%. Researchers found that birds – especially birds that hunt from high in the sky such as eagles, hawks and other raptors – experience “motion smear” that prevents them from seeing a fast moving, monochromatic object up close. They don’t see it because their retinas can’t keep up with the velocity of the blade. With one blade painted black, it creates a contrast between the blades, increasing visibility and reducing the motion-smearing effect, researchers found.

Since December 2023, the OSU and PacifiCorp team has added black paint to 28 turbines and plans to finish painting eight more this year. In a news release, Hagen said the Norwegian study used a smaller sample size and that the researchers wanted to see whether they could measure the effect on a larger variety of birds as well as bats by painting more turbines.

Calcium sulphur batteries (uwu)

Okay, so, i've become interested in z-pinch studies for aerospace purposes (i'm really excited about the prospects, everything works on paper, but i naturally want to actually witness p+N14 fusion for above 0.01% of available protons before i go trying to get the materials to build a real liquid fueled SSTO fusion rocket, especially since there are thousands of folks way smarter than me who have presumably thought of this before and we don't have it yet, so yeah). Anyways, if i want the extremely large electricity input without making my electricity bill higher than a whole month's rent and getting my roommates mad at me, i'll need to collect solar or wind in a battery bank. Since lithium batteries are just about all immoral and expensive (yes i am writing this on a device powered by lithium batteries, it would be lovely if capitalists would take a hint and switch to things that just objectively perform better and are cheaper, but whatever), i figured this would be a nice excuse to experiment around with some new battery designs. Since all of them will require sulphur, i won't be able to really get into it before mid may due to some concerns about the smell and risks of getting sulphur powder everywhere (it's very yellow and hard to clean out), but i felt i might as well share my preliminary ideas. First off, in order to make the organic sulphur polymer, i'm looking to explore mostly citrate based polymers, perhaps with phenylalanine mixed in in order to both give more bulk as well as providing nitrogens for sulphenamides to form. Since i'll need urea later, i was also considering partially polymerizing urea with citric acid and adding that into the molten sulphur mix, but i'm less confident in the stability of that and a bit concerned about the potential noxious fumes produced. Regardless, that's the short of the sulphur cathode, details will definitely change after i refind that paper which went over a great way of preventing insoluble polysulphide production. I'm also gonna experiment with anode material and even the ions i use. I know i said "calcium sulphur batteries" in the title, but due to how common aluminium is and how much easier magnesium is to work with (and the fact that their specific energies are higher), i'll also be considering those two. Even beyond that, there are so many potential anode materials, including even amorphous carbon and carbon nitrides which i'd love to test since there's just so much to improve on and i'd rather do a lot of experiments with cheap to make materials and potentially land on a great solution than accept something subpar because it took less effort. Anyways, of the materials i plan on using, there's magnesium sulphate, aluminium sulphate, calcium chloride, potentially other calcium salts (is the salt with taurine soluble in water? IDK, can't find an answer so i'll test it), charcoal, vegetable oil, urea, and phenylalanine. Those may seem like an unrelated hodgepodge of compounds, but they've been chosen because they're what i have/will soon have and they're also all extremely cheap. If the urea works out well in the battery, i may have to make this project a meme and attempt to make a z-pinch device with as much urine as possible (use it to make ammonia for the plasma, to make the batteries, and i'm sure there's some way to use urine in a capacitor (maybe just distilling off the water to use as a dielectric? idk, it's been a while since i tried making a capacitor)).

Anyway, i really didn't expect this long trainwreck of a post to end with discussions of urine, but what can you do? This is all probably nonsensical, even by my standards, but basically i want batteries and i think i can make them cheaper per megajoule of stored energy than the ones i could buy, even accounting for the inevitable failed experiments.

There is hope. I promise. Young people just won their case against the state of Montana. Ecuadoreans braved escalating political violence to vote against oil drilling in the Amazon. Brazilian deforestation is down by enormous amounts since Lula took office. They’ve invented hydropanels that synthesise pure water from the air. People are farming in solar parks. A ship just launched for its maiden voyage using rigid sails designed to mimic wind turbine blades. EV sales are taking off, and, more crucially, cities are re-assessing their very relationship with the car. By the 2024 Olympics the river Seine will be safe for people to swim in again. More and more people are replacing their gas boilers with heat pumps. Solarpunks are growing crops in their back garden and distributing them to their neighbours. Great tracts of land are being given back to nature. Young people are channelling their energies into meaningful careers. Pilots are leaving the aviation industry. Yes, the world is dark and terrible and full of awful dangers that keep you up at night, but we are a huge movement that grows every day in numbers and power. Your small actions matter. Our collective triumphs are increasing. Things are going to get harder, extreme weather will be more common, but with ingenuity, resilience and crucially, COMMUNITY, we can build an equitable world on this strange, tired old planet. See you in the future.

as a huge lover of birds, 90% of the concern against wind turbines being used for energy is literally just pro fossil fuel propaganda. birds ARE at a risk however there is a lot of strategies even as simple as painting one of the blades that reduces a lot of accidental deaths. additionally renewable energy sources will do more in favor of the environment that would positively impact birds (and all of us). one study found over one million bird deaths from wind turbines. while that is a shockingly high number and we should work to drastically shrink it, at least 1.3 billion birds die to outdoor cats on a yearly basis. it was never about caring about birds

Turbine Blades Have Piled Up in Landfills. A Solution May Be Coming. (New York Times)

Excerpt from this New York Times story:

The blades on the newest wind turbines sweep an area longer than a football field and are nearly impossible to recycle.

At the end of their life span of around 20 years, they are chopped into pieces and buried in a handful of landfills across the Great Plains. Those few sites in Wyoming, Iowa and South Dakota have a spooky nickname: wind turbine graveyards.

But this waste problem from a growing source of low carbon energy could become a headache of the past.

Researchers at the National Renewable Energy Laboratory have developed what they say is a turbine blade made from plant material that can be recycled. The new substance is made from inedible sugar extracted from wood, plant remains, used cooking oil and agricultural waste.

They say the prototype they developed can perform as well as traditional blades that are made from a combination of fiberglass and plastic and which have been very difficult to reuse.

The new, recyclable material could be easily adopted by industry, said Robynne Murray, one of the researchers at the national laboratory.

Because the blades for wind turbines are shaped in large molds, which can take up entire warehouses and are expensive to build, it is critical for any new material to be compatible with existing molds and production facilities. And the substance developed by the national laboratory does exactly that, Dr. Murray said.

It’s “designed to be a drop-in replacement,” she said. “Manufacturers should be able to just take it and use it.”

Blades made from the new materials could be 3 to 8 percent more expensive than traditional blades, according to one estimate.
