Product quality is not only determined by the color-coated basic properties of the substrate and the coating, many factors affect product quality, understanding of various defects also vary, but in general can be divided into poor quality substrate, coating the surface tension It changes, before mishandled curing defects, painting defects and scratches. This data shows that the competitive pressures in the domestic market continues to increase buying volume Color, on the one hand, domestic products instead of foreign products; the other hand, where the volume sold Color, down exports, resulting in this part of the production of direct release country. Therefore, it should be tested periodically for oil cleanliness. Another hydraulic system maintenance work on the system of regular inspections of hydraulic components, the most important is the servo valve regular inspection and maintenance. Pre-coated coil (color coated) is specialized in the production plant through specialized continuous production process to produce the product, the product must meet the national quality inspection standards. Color coated aluminum coil using a wide range, can be used for architectural aluminum panels, aluminum honeycomb, corrugated sheet roof, fireproof plywood, aluminum ceilings, furniture, blinds, shutters, garage doors, awnings, gutters and other fell into the water, electrical and electronic aspect can be used for computer chassis, electrical panels, lighting, solar reflectors, air conditioning ducts and the like. Because color coated aluminum coil is rich in color, in residential, commercial outlets and Convention Center Color volume quotes, color coated aluminum coil can be worth considerably. Mouth scratches, color-coated steel substrate during baking furnace volume, wiping his mouth due to fluctuations in steel will scratch the film on the substrate, the solution is to check the sag and tension numerical control device, the original plate specifications and then situation beating properly adjusted; the reason is that the speaker volume produced: edge waves, thick coating side, cut or burr burring, edge pinch stacking and other causes speaker volume.
