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. 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. As people's research progresses, the field of application of vinyl resins is also constantly expanding, and emerging applications continue to emerge. Wind turbine blade and oil tank anti-corrosion are just two emerging, vinyl resin applications have broad prospects for development. Regarding the application of wind power blades, according to experts, the use of more cost-effective vinyl resins, gradually replacing 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 that it can reduce the cost of the blade. The current price of vinyl resin is about RMB 30/kg, and the epoxy resin is about RMB 40/kg. Only the replacement of the blade material can reduce the cost by about 10%. DSM Composite Resin Group Jinling DSM Resin Technology Co., Ltd. said that 10% is only a very conservative estimate. After the replacement of the main blade material, the surface covering products such as gel coats will also be changed accordingly, and the savings will be equally significant. In addition, the cost of molds in the production of blades is very high. After the materials are replaced, no post-curing treatment is required, which will greatly increase the efficiency of mold use. Taking a 1.5mw blade as an example, the mold cost is about 3 to 4 million yuan. It takes about two days to produce a blade using epoxy resin as the base material, and vinyl resin is only used for one day. In addition, since the vinyl resin is similar to the main material of the other blade, the unsaturated polyester resin, it can also be used as a reference to the mature process for preparing the blade from the existing unsaturated resin. According to experts, it is worth mentioning that, although vinyl resin has a great advantage, its application development is still in its infancy, and domestic and foreign companies are actively conducting research on the application of vinyl resin on the blade. Application of anti-corrosion on the tank The vinyl acetate resin glass steel and its glass flake resin coating have excellent corrosion resistance and easy construction, and can completely solve the existing anti-corrosion problems of petroleum storage tanks. China's imported crude oil has high sulfur, heavy quality, and large-scale construction of new crude oil tanks. Experts said that the coastal layout of crude oil reserve tanks has caused the existing oil storage tanks' anti-corrosion system to be greatly challenged. Polyurethane anti-corrosion coatings, etc., in the acid and alkali resistance, solvent resistance and heat resistance, especially in highly corrosive media, high temperature conditions, can not fully meet the anti-corrosion requirements. It is the matrix resin that plays a decisive role in the preservation of the paint. Therefore, to change the status quo, it is necessary to start from the choice of resin. According to experts, at present, anti-corrosion coatings for petroleum storage tanks are generally made of high-heat-resistance, acid-resistant, and alkali-resistant vinyl acetate resin fiberglass and vinyl vinegar glass flake resin coatings to solve the highly corrosive crude oil belts. Into the steel oil storage tank corrosion problems. There are also domestic manufacturers of vinyl resins used for anti-corrosion of oil tanks, and their anti-corrosion effect is also very good. It is believed that tank anti-corrosion will become a large market for vinyl resins in the future. An anchor assembly that enables anchor points for weight lift and for height entry or fall protection. The assembly of the present disclosure generally includes: a stud, an external elongated surface with load-bearing threads, and a through tunnel fabricated on the stud , the through-tunnel intersects and is perpendicular to the longitudinal axis of the stud; member comprising an eyelet surrounding the opening and a pair of retainers extending from the eyelet, each retainer defining a hole at its central axis , and defines a hole having a diameter 0.1 to 2 mm larger than the diameter of the stud; the retainers are spaced apart from each other for receiving the stud through the hole, and are axially aligned with a cavity of predetermined length; a nut with sidewalls , the sidewall defines an internally threaded passage through which the nut is fixable to the stud and located within the cavity for insertion between the pair of retainer members, the nut on the side The wall has a pair of axially aligned and radially extending through holes; the through holes are adjustably aligned with the passage tunnel to form a continuous passage thereof; and a pivot pin that can be filled through the through holes and Passage through the tunnel to lock the nut onto the stud. The eyelet of the assembly of the present disclosure is configured to be rotatable about the longitudinal axis of the stud, and the locked nut prevents movement of the member along the longitudinal axis of the stud.
