According to experts from China Unsaturated Resin Network (www.upr-e.cn), vinyl resin is an internationally recognized highly corrosion-resistant resin, which has been widely used in ships, yachts and other industries, and its performance has also been confirmed . Vinyl resin is an internationally recognized highly corrosion-resistant resin, which has been widely used in ships, yachts and other industries, and its performance has also been confirmed by many parties. With the continuous progress of people's research, the application fields of vinyl resins are also constantly expanding, and emerging application fields are constantly emerging. Wind power blades and oil tank anti-corrosion are just emerging, and the application field of vinyl resin has broad development prospects. Regarding the application of wind power blades, according to experts, the use of more cost-effective vinyl resins to gradually replace the currently widely used epoxy resin will become the future development trend of wind power blades. The most prominent advantage of using vinyl resin instead of epoxy resin is to reduce blade cost. The current price of vinyl resin is about 30 yuan/kg, and epoxy resin is about 40 yuan/kg. Only the replacement of the blade material can reduce the cost by about 10%. After the blade main material is replaced, the supporting products such as gel coat and other surface protection layers will also be changed accordingly, and the saving effect brought is also considerable. In addition, the cost of the mold accounts for a high proportion in the blade production. After the material is replaced, there is no need for post-curing and other treatments, which will greatly improve the efficiency of the mold. Taking the 1.5mw blade as an example, the cost of the mold is about 3 million to 4 million yuan. It takes about two days to produce a blade with epoxy resin as the base material, but only one day with vinyl resin.
In addition, because vinyl resin is similar to the other main material of the blade-unsaturated polyester resin, it can also learn from the maturity of the existing unsaturated resin to prepare the blade
Craftsmanship. According to experts, it is worth mentioning that although vinyl resin has great advantages, its application development is still in its infancy, and domestic and foreign companies are actively
Carry out research on the application of vinyl resin on the blade. Vinyl vinegar resin glass fiber reinforced plastics and glass flake resin coatings for anti-corrosion of oil tanks have excellent corrosion resistance
Energy and easy construction, can completely solve the existing anti-corrosion problems of petroleum storage tanks. According to experts from China Unsaturated Resin Network (www.upr-e.cn), my country imports crude oil with high sulfur content,
Heavy quality and large-scale construction of new crude oil tanks. Experts said that the coastal layout of crude oil storage depots has made the anti-corrosion system of existing oil storage tanks greatly challenged.
The epoxy resin coatings and polyurethane vinegar anticorrosive coatings, etc., in terms of acid and alkali resistance, solvent resistance and heat resistance, especially in strong corrosive media and high temperature conditions, cannot be fully satisfied
Anti-corrosion requirements. And it is the matrix resin that plays a decisive role in coating corrosion protection. Therefore, to change the status quo, we must start with the choice of resin. According to Chinese experts, currently abroad
Anti-corrosion coating of petroleum storage tanks is made of vinyl vinegar resin glass fiber reinforced plastic and vinyl vinegar glass flake resin coating with high heat resistance, acid resistance and alkali resistance to solve high corrosion
The anti-corrosion problem in steel oil storage tanks caused by crude oil. Domestic manufacturers also produce vinyl resins for anti-corrosion of oil tanks, and its anti-corrosion effect is also very good. I believe that anti-corrosion of oil tanks will
There is a big market for vinyl resins in the future.
