First processing impurities. Phosphate slag mainly caused by large particles of impurities and phosphate film yellow rust caused by small impurities into the film. And when you only need to clean the spray tank and phosphate slag accumulation in the pipeline, in proportion to control the concentration of the phosphate bath. Water impurities. Mainly the water, a small amount of sand used are salt, which had caused large impurities. Increased water filter that uses water to do for the last two stages of cleaning water. Curing oven impurities. In the wall for thorough cleaning the oven with a damp cloth and vacuum cleaner, with a focus crevice chain hanging duct. If it is a large black particulate impurities need to check the air filter is damaged at tube with the change in time. Powder impurities. Mainly powder additive excessive, uneven pigment dispersion, powder pink points by pressing cause. Improve powder quality, improved powder storage mode. Means for coating metal, plastic, wood and other materials processed into products, spray plating, its surface is covered with a protective layer or sprayed decorative layer. Development of coating technology and equipment experienced by the manual to automatic production line machinery and equipment and then to the development process. Painting equipment industry in the introduction of the true origin of the fifties, when the Soviet technology. Starting from the 1960s, spray plating how to use? , Due to the development of light industry, insulating paint spray plating, first appeared in the bicycle manufacturing industry automated production lines, the main task of painting industry during this period was mainly to corrosion. But with the rapid economic development of the interior, as well as efficient coating technology progress abroad, through the exchange of technology and the introduction of foreign technology, spray plating what? , Painting technology began rapid development of China, in painting automated production, development and promotion of spraying equipment and electrophoretic coating technology to promote the application and powder coating technology, the coating equipment has obviously made great progress and development. What spraying plating is? Spray plating, spraying sand hung hardware appliances provided by the Dongguan City, Sha Hong Hardware Electric Co. Dongguan City, Sha Hong Hardware Appliance Co., Ltd.
