Technological innovation vinyl resin opens a new space for application

vinyl resin is an internationally recognized highly corrosion-resistant resin. At present, it has been widely used in the physical and mechanical property testing industry of bricks and blocks in ships, yachts and other industries. With the expansion of application fields, wind turbine blades and oil tank corrosion prevention will become two emerging application fields of vinyl resin

it is understood that using vinyl resin with higher cost performance to gradually replace the epoxy resin widely used at present will become the development trend of wind power blades in the future. The most outstanding advantage of replacing epoxy resin with vinyl resin is that it can reduce the cost of blades. The current price of vinyl resin is about 30 yuan/kg, epoxy resin is about 40 yuan/kg, and only blade material 4 Reduce the distance between the two by 1.2-2mm, and the cost can be reduced by about 10% by changing the influence of the good degree on the color difference. DSM composite resin group Jinling company technicians said that 10% is only a very conservative estimate. After the main material of the blade is replaced, the surface protective layer supporting products such as gel coat will also be changed accordingly, and the saving effect is also considerable

vinyl resin has another advantage in the field of wind power: the cost of mold accounts for a high proportion in blade production. After replacing dioxygen resin with this material, post curing and other treatments are not required, which will greatly improve the efficiency of mold use. Taking the blade of 1.5MW as an example, the mold cost is about 3million ~ 4million yuan. It takes about two days to produce a blade with epoxy resin as the substrate, while it takes only one day with vinyl resin. In addition, because vinyl resin is similar to unsaturated polyester resin, another main material of leaves, it can also learn from the mature process of preparing leaves with existing unsaturated resin. It is worth mentioning that although vinyl resin has great advantages, its application and development is still in the primary stage, and domestic and foreign enterprises are actively carrying out the application research of vinyl resin on leaves

oil tank corrosion prevention is another emerging application field of vinyl resin. Vinyl acetate resin FRP and its glass flake resin coating have excellent high corrosion resistance and simple construction, which can completely solve the existing corrosion problems of oil storage tanks

with the high sulfur and heavy quality of China's imported crude oil, the large-scale construction of new crude oil tanks, and the layout of crude oil storage depots in coastal areas, the anti-corrosion system of existing oil tanks has been greatly challenged. In the past, the commonly used epoxy resin coatings and polyurethane anti-corrosion coatings cannot fully meet the anti-corrosion requirements in terms of acid-base resistance, solvent resistance and heat resistance, especially in terms of resistance to strong corrosive media

it is the matrix resin that plays a decisive role in the anticorrosion of coatings. Therefore, in order to change the current situation, we must start with the selection of resin. According to experts, at present, vinyl acetate resin FRP and vinyl acetate glass flake resin coatings with high heat resistance, acid resistance and alkali resistance are widely used in foreign countries to manufacture oil storage tanks. Many partners have also developed various simple methods to identify the functional corrosion coatings of smooth oil, so as to solve the internal corrosion problems of steel oil storage tanks caused by highly corrosive crude oil. Domestic manufacturers also produce vinyl resin for oil tank corrosion prevention, which has achieved good corrosion prevention effect. Oil tank corrosion prevention will become a big market for vinyl resin in the future
