The so-called coating refers to covering the metal and non-metal surface protective layer or decorative layer. With the development of industrial technology, coating has been developed from manual to industrial automation, and the degree of automation has become higher and higher. Therefore, the application of coating lines has become more and more extensive, and has penetrated into many areas of the national economy. The development of our country's coating production line has experienced the development process from manual to production lines to automatic production lines.
China's coating process can be simply summarized as: pretreatment → spraying → drying or curing → three waste treatment. The coating industry in China really originated after the introduction of Soviet technology in the 1950s. (China Gold Packaging Network is a portal of the metal printing and packaging industry.) A number of construction projects have begun to establish coating production lines, but these production lines are generally steel plate welded tanks with steel structure spray (paint) paint room and drying room (furnace ) In combination, the electric hoist is used to manually suspend the workpiece (a few of the suspension conveyors) to operate. At that time, the pickling tanks were generally made of lead-lined steel plates. With the development of the times, there appeared to be lining glass steel or all glass fiber reinforced plastic tanks.
Since the 1960s, due to the development of light industry, first of all, in the bicycle manufacturing industry, there have been assembly lines for mechanized production and automated production lines, as well as program-controlled production lines formed by program-controlled cars on the basis of the production of existing tank production lines. In Shanghai and Tianjin area. During this period, the main task of China's coating industry was to use anti-corrosion as its main task.
However, with the development of China's economy and the development of foreign coating technologies, China's coating technology has begun to develop rapidly through technology introduction and exchanges with foreign technology. In the area of ​​automatic coating production, electrostatic spraying and electrophoretic coating technology Promotion and application, powder coating technology development and promotion, especially in China's home appliance industry, daily hardware, steel furniture, aluminum components, electrical products, automotive industry and other areas of vigorous development, so that the coating industry has made significant progress. Intelligent coating robots also appeared in the coating line.
