Problems solved by technology

However, since the anti-corrosion paste and anti-corrosion tape are mineral grease products, they will be lost to varying degrees at high temperatures. In addition, as a protection and sealing cover, it is directly in contact with the mineral grease in the anti-corrosion tape during production. The rise causes petrolatum to flow at high temperature, and the channel formed by the flow is difficult to achieve complete sealing in the process of making the protective cover. At the same time, due to the complex construction environment on site, it is difficult to ensure absolute controllability of the quality, so there are different degrees of loss of anti-corrosion components after completion. However, the anti-corrosion performance and weather resistance of the unsaturated polyester resin gel coat used in the system are poor, and the outer surface of the gel coat is easily contaminated with powder ash. and other air pollutants, and the coating is easy to yellow and fall off, which seriously affects the appearance; at the same time, the anti-corrosion system does not have the function of flame retardancy
