Environmental protection background in the painting industry

As a major manufacturing country for industrial products in the world, China's painting industry is particularly important; Coating is mainly used to protect metal and non-metal surfaces, extend the service life of items, increase aesthetics, and provide special functions such as fire prevention, waterproofing, and corrosion prevention by covering with protective or decorative layers; To meet the needs of market competition, many manufacturers are constantly increasing their efforts in technological transformation and improving the quality of product coating; However, while painting is developing, there is a lack of sufficient attention to environmental protection and energy conservation, and corresponding supporting measures are not perfect. The environmental protection processes and equipment used in painting production lines are still far from meeting the requirements of sustainable environmental development, and the problem of "three wastes" is becoming increasingly severe.
