Further, the surface roughening treatment equipment (1) is arranged at the beginning end of the production line, at least one group of sand blasting devices or shot blasting devices or mechanical polishing facilities are arranged inside the equipment, and an air draft purification device, a recovery device and the like are arranged. Compared with the traditional rust removal method by sand blasting or shot blasting, the method aims at not removing rust, but roughening the surface to further activate the surface, so that the plastic coating layer is combined with the steel plate matrix more firmly, and the plastic coating quality is improved. Because of different purposes, the air pressure required by the spray gun is smaller, the spray gun is cheaper, and the production cost is lower.
Furthermore, at least one group of plastic spraying devices are arranged inside the plastic coating equipment (2), can be manually brushed or mechanically sprayed, and is provided with an air draft purification device, a recovery device and the like. The process can meet the regulation and control requirements on plastic coating parameters by controlling parameters such as powder materials, coating thickness and the like.
Furthermore, a heating device is arranged in the curing equipment (3), and an electric heating mode or a gas heating mode can be adopted. The equipment can heat the plastic-coated steel plate to a specified process temperature, and the plastic-coated steel plate is taken out after the process time is reached to form a steel plate plastic-coated product.
