Pretreatment method for anticorrosion of color-coated plates is widely used in airport terminals, aircraft maintenance hangars, color steel plates, stations and large transportation hubs, conference and exhibition centers, stadiums, exhibition halls, large public entertainment facilities, public service buildings, large shopping centers, commercial facilities, residential buildings and other buildings. This roofing system is the same as the ancient iron barrels, and its waterproof performance is also the best. Compared with other materials, the service life has been greatly improved, and the surface will not rust due to long-term use. The level of anticorrosion performance of color-coated plate design is the focus of the next improvement, which involves the cost, durability, performance, maintenance cost and many other issues of color-coated plates.
Pretreatment method for anticorrosion of color-coated plates! The general treatment is shot peening and shot blasting. Shot peening: Shot peening and sand blasting together constitute shot peening. Shot peening has obvious surface treatment effect, but the grinding force is relatively large, so ultra-thin plates are easy to deform. Sand blasting has the best cleaning effect and is suitable for surface treatment of various workpieces. Give full play to the thermal insulation of the color-coated roof, especially in the relatively cold winter, pay attention to the humidity of the insulation cotton and the connection method between the metal roof and the lower structure to enhance the reflective effect of the roof.
