The search index of ppgi galvanized steel coil has increased by 35 percentage points over the same period last year, which shows that the development prospects of ppgi galvanized steel coil is broad and have been moving forward steadily. So, do you know what to pay attention to when producing color-coated plates?
The quality of the ppgi galvanized steel coil and its basic selection of materials, production technology and production methods have an important relationship, especially in the production, we must pay attention to some details, otherwise it will affect the product quality. We need to pay attention to production, we know that this knowledge can solve some defects well.
Blunt eventually leads to aging of the prepainted steel coil , and scratches and paint defects appear on the shape. Due to the problem of paint resin raw materials, the primer and the passivation layer are not well combined. Until the two ends of the board are fixed. A simple and effective method is to clamp the overlapped steel plates with a pair of clamps respectively. Dust will affect the surface quality of the finished color-coated board, especially the quality defects of the aging of the color-coated board. The color-coated coil should be placed on rubber pads, skids, brackets and other devices, and the lashing strap lock should be upward, and cannot be placed directly on the ground or transportation tools.
After removing the anti-rust oil, rust spots and dust attached to the surface of the ppgi galvanized steel coil, chemical coating is applied to the clean substrate production surface to form a networked chemical conversion film, which improves the adhesion of the substrate and the coating, and improves the substrate The corrosion resistance and durability of the coating. The product obtained by applying an organic coating on the hot-dip galvanized steel sheet is a hot-dip galvanized ppgi steel coil.
