Color steel coils focus on the development of new coatings, and improve the general polyester, polyvinylidene fluoride (PVDF) and plastisols to obtain super color reproducibility, UV resistance, sulfur dioxide resistance, and improve corrosion resistance; Functional coatings such as heat. Unit equipment is more complete.
Such as the use of new welding machines, new roller coating machines, complete curing furnace, equipped with advanced automated instruments. Because cold embossing has lower cost than hot embossing, and has the characteristics of beautiful appearance, three-dimensional feeling and high strength, cold embossing production technology has become a development trend. First clean the dust on the surface of the color steel tile.
Then use an electric grinder or a wire brush or abrasive cloth to clean the rust and oxide on the metal surface, and then use cotton yarn or rags to clean the floating dust on the metal surface. Severely rusted areas can be struck with an iron hammer to shake off the thicker rust. If there is oily place, use gasoline or thinner to scrub it. In particular, pay attention to the rust removal at the bolt connection and the weld. The rust removal level must reach ST2 level, and the metal luster is completely exposed.
First, clean the dust on the surface of the color coated steel coil, then use an electric grinder or a wire brush or abrasive cloth to clean the rust and oxide on the metal surface, and then wipe the dust on the metal surface with cotton yarn or rags. Severely rusted areas can be struck with an iron hammer to shake off the thicker rust.
