Color coated plate products are mainly made of color coated coiled materials. Before installing the next steel plate, each color coated steel plate must be completely fixed. The fixing must start from the center of the color coated plate to prevent moisture, then extend to both sides, and finally fix the overlapping edge of the color coated plate. It has become an increasingly popular new building material. The working quality determines the coating quality and directly affects the physical storage indexes such as flexibility and impact resistance of the coating.
In addition to the protection of zinc, the organic coating on the surface of the hot-dip galvanized color coated plate also plays a role in insulation protection and preventing rust during storage. The service life of the color coated plate is longer than that of the hot-dip galvanized plate. For the roofs, walls and doors mainly used in steel structure plants, airports, warehouses, refrigeration and other industries and trade buildings in the construction industry, few civil buildings use color steel plates. The increase in domestic production of galvanized sheet is mainly due to the increase in the production of hot-dip galvanized sheet. From 1998 to 2002, the production of hot-dip galvanized sheet increased from 970000 tons to 2200000 tons. The storage location of color coated sheet should be reasonably arranged to facilitate access and minimize unnecessary movement. The passivation film thickness of color coating is not monitored, so the passivation quality cannot be guaranteed.
In addition, when the color coated plate is stored damp, the surface of the plate will change, resulting in scratch and paint loss during molding. The epoxy self leveling floor or advanced wear-resistant plastic floor can be used as the board surface, and the anti-static type can be selected if there are anti-static requirements.
