Coating detached from the base down, mostly in machining and application process, Reflections from the spraying process, the primary cause of peeling are: 1. the appearance of artifacts oxide, oil, rust, dust, moisture goods for Ex ; 2. lack workpiece preheating temperature; 3. bottom is too thin, and the contact with the workpiece base is not strong; 4. coating is too thick and uneven, resulting in greater stress within the coating, when the internal stress of the coating beyond coating when its own strength, the coating cracking; 5. spray hole is buying spray processing, cooling coating shortened simply fall off resulting spray processing, spray as much as possible and thus get thinner, to reduce the shortening rate of cooling. In addition, after spraying cooling too quickly will cause the falling arc spray coating of steel structure corrosion, abrasion and mechanical parts repair and other projects in the most common practice to use a thermal spray approach. Arc spraying system is usually caused by spraying a dedicated power supply, control equipment, electric arc spray gun, wire feeder and compressed air supply system and the like. Wooden doors, furniture manufacturing increasingly prosperous today competition aluminum coating process, the industry has become even more intense, manufacture and sale of doors getting lower and lower profit margins. How to maximize control costs, improve quality, increase production efficiency, especially to get rid of dependence on human production, which is placed in front of the main topics of every enterprise. The doors of businesses essentially production orders, can not be mass-produced, and factories received more orders in order to compete with each other, shorter and shorter delivery contract. The doors are mostly labor-intensive production, many processes require people to manually operate the step in which the paint is the top priority, the quality of the paint process and processing speed will determine the quality of the final product delivery cycle. As consumers increasingly fancy doors of surface effects, PU, ??PE, AC, NC paint to match the technology is also being more and more businesses use. But these traditional paints are facing a problem - long curing time of three anti-paint coating process, can not be achieved pipeline operations, but also dependent on the climate is very large. Waste paint large, high dependence on paint spray. Aluminum spray processing | Sha Hong Hardware Electric spray | spray process provided by the Dongguan City, Sha Hong Hardware Electric Co.
