Wind power and chemical corrosion prevention will become two major markets of vinyl resin

vinyl resin is an internationally recognized highly corrosion-resistant resin. At present, it has been widely used in shipbuilding, yacht and other industries, and its properties have also been confirmed by many parties

vinyl resin is internationally recognized as a highly corrosion-resistant resin that will show the "one basket" solution for the lightweight utilization of aluminum alloy from the development of aluminum alloy materials, body structure design, part molding, connection assembly and other aspects. At present, it has been widely used in shipbuilding, yachting and other industries, and its properties have also been confirmed by many parties. With the continuous progress of people's research, the application field of vinyl resin is also expanding, and new application fields continue to appear. Wind turbine blades and oil tank corrosion prevention as two emerging, vinyl resin applications have broad prospects for development. As for the application of wind power blades, according to experts, 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, and that of epoxy resin is about 40 yuan/kg. Only the replacement of blade materials can reduce the cost by about 10%. DSM composite resin group Jinling DSM resin Co., Ltd. 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

in addition, the mold cost accounts for a high proportion in blade production. After replacing the material, there is no need to carry out post curing and other treatments, 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. According to experts, 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. The application of vinyl acetate resin FRP and its glass flake resin coating on oil tank corrosion prevention has excellent high corrosion resistance and simple construction, which can completely solve the existing corrosion prevention problems of oil storage tanks

China's imported crude oil is high in sulfur, heavy in quality and large in new crude oil tanks. Experts said that the coastal layout of crude oil storage depots has greatly challenged the anti-corrosion system of existing oil tanks. In the past, the commonly used epoxy resin coating and polyurethane anti-corrosion coating, etc. in terms of acid-base, solvent resistance and heat resistance, the sensor is responsible for such conversion, especially in highly corrosive media and high temperature conditions, It can not fully meet the anti-corrosion requirements. The matrix resin plays a decisive role in coating corrosion prevention. Therefore, to change the current situation, we must start with the selection of resin. According to Chinese experts, vinyl acetate resin FRP and vinyl acetate glass flake resin coatings with high heat resistance, acid resistance and alkali resistance are widely used abroad to make anti-corrosion coatings for oil storage tanks to solve the internal corrosion problems of steel oil storage tanks caused by highly corrosive crude oil. There are also domestic manufacturers producing vinyl resin for oil tank corrosion prevention. The anti-corrosion effect detection, compression and bending test machine needs to pay attention to what results are also very good. It is believed that oil tank corrosion prevention will become a big market for vinyl resin in the future
