History of painting in China

Coating is an important link in the surface manufacturing process of construction machinery products. The quality of anti-rust and anti-corrosion coating is one of the important aspects of the overall quality of the product. The appearance quality of products not only reflects the protection and decoration performance of products, but also constitutes an important factor of product value.
The so-called coating refers to the covering of metal and non-metal surfaces with a protective or decorative layer
With the development of industrial technology, painting has been developed from manual to industrial automation, and the degree of automation is getting higher and higher, so the application of painting production line is more and more extensive, and into many fields of the national economy. The development of painting production line in China has experienced the development process from manual to production line and automatic production line.
The painting process in our country can be simply summarized as; Pretreatment → Spray drying or curing → waste treatment.
China's painting industry really originated in the 1950s after the introduction of Soviet technology. In some assisted projects, painting production lines began to be established, but these production lines are generally a combination of steel plate groove plus steel structure spray (coating) paint room and drying room (furnace), and the workpiece is manually hung by the electric hoist (a few use suspension conveyor). At that time, pickling tanks were generally steel plate lined and with the development of The Times, there were channels lined with fiberglass or all made of fiberglass.
Since the 1960s, due to the development of light industry, there have been mechanized production lines and automated production lines in the bicycle manufacturing industry, as well as program-controlled assembly lines formed on the basis of the original slot sub-assembly line production, which are mainly in Shanghai and Tianjin. During this period, the main task of China's painting industry is still to anti-corrosion.
But with the development of our economy, and the development of coating technology abroad, through technology introduction and communicate with foreign technology, the coating technology began to rapid development of our country, in terms of coating automatic production, electrostatic spraying and electrophoresis paint technology popularization and application, development and popularization of the technology of powder coating, especially our country home appliance industry, daily hardware, steel furniture, The vigorous development of aluminum components, electrical products, automotive industry and other fields has made obvious progress in the painting business, and intelligent spraying has also appeared in the painting production line
