The search volume of color-coated plates has increased by 35 points compared with the same period, which shows that the development of color-coated plates has a bright future and has been making steady progress. So, do you know what you must pay attention to when making it?
The quality of pre painted steel coil is basically closely related to the selection of raw materials, production processes and manufacturing methods. Especially in the production and manufacturing, there are some key points to pay attention to, otherwise it will endanger the product quality. We must pay attention to manufacturing. We know that this kind of expertise can deal with some defects very well.
The blunt tool will eventually cause the aging of the pre painted steel coil, resulting in scratches and paint defects on the appearance. Because of the raw material problems of epoxy resin and paint, the top coat and the passivation layer are not well integrated. Until the two sides of the board are fixed. A simple and reasonable way is to use a pair of tooling fixtures to clamp the overlapping thick steel plates. Dust will endanger the surface quality of the finished color-coated panels, especially the aging quality defects of the color-coated panels. They should be placed on rubber sheets, spacers, support frames and other equipment. The binding belts should be locked upwards. Put it on the road or vehicle.
After removing the rust inhibitor, the rust and dust adhering to the pre painted steel coil and the surface of the organic chemical architectural coating are applied to the green manufacturing surface of the substrate to produce an organic chemical conversion film with a network structure, which improves the substrate and the building. The adhesion between the coatings improves the corrosion resistance of the substrate and the performance of architectural coatings. The product obtained by applying an organic coating on the hot-dip galvanized steel sheet is a hot-dip galvanized pre painted steel coil.
