Painting is an important part of the surface manufacturing process. Anti-rust, anti-corrosion, aesthetics, and changing the use of the material itself disadvantages are that the quality of the coating is one of the important aspects of the overall quality of the product. The appearance quality of the product not only reflects the protection and decoration performance of the product, but also is an important factor that constitutes the value of the product, and the coating equipment is a crucial part of the entire coating process. The main coating equipment is divided into surface pretreatment before coating. Equipment, painting equipment, film drying and curing equipment, mechanized conveying equipment, dust-free constant temperature and humidity air supply equipment, etc. and other auxiliary equipment.

The continuous development of science and technology, the continuous emergence of new technologies, new materials and new processes, the development of electronic technology, numerical control technology, laser technology, microwave technology and high-voltage electrostatic technology, automation, flexibility, intelligence and integration of coating equipment Modernization has brought new vitality, making the variety of machine tools continue to increase, and the technical level continues to improve. Taken together, its development trend has the following aspects:
(1) Improve the comprehensive utilization rate of coatings and reduce waste, making the coating process more environmentally friendly and greener.
(2) Numerical control automation, simple operation and efficiency are doubled.
(3) Continuous promotion of the streamlined operation model.
(4) Application of high technology.
(5) Develop a flexible and integrated coating production system.
(6) Safe and pollution-free coating production system.
The high-clean organic coating equipment has the characteristics of flat plate shape, high apparent quality requirements, smooth and delicate coating film, and soft color; and the coating film has strong adhesion and good bending processing performance. Under the premise of various complex processing, coating The layer does not crack or peel; it has certain anti-pollution ability, easy cleaning and scrub resistance, and is mostly used in walls such as clean rooms.
With the continuous development of my country's economy, especially the rapid growth of high-tech industries such as electronics, biology, and medicine in recent years, coating equipment clean rooms are widely used in various industries. widely used.
The cleanliness levels of electronic workshops, hospitals, and food processing workshops are divided into ten thousand, one thousand, and one hundred from low to high. The 100-level cleanliness often refers to a space of 1 cubic foot, which is greater than or equal to 0.5 microns. There must be no fewer than 100 particles, class 10 is 1 cubic foot of space, no fewer than 10 particles of 0.5 micron size, and no more than 1000 particles in class 1000.
To make the utilization rate of various coating equipment reach a relatively high level, it is necessary to establish a reasonable coating production line: first, we must determine the production program, complete the process design, and plan the plan, and then we can design, manufacture and install non-standard equipment. Therefore, Process design and program planning are the basis for establishing a production line. Correct and reasonable routes will have a decisive impact on production operations and product quality. The content of process design mainly includes: pre-treatment methods for workpiece surface coating quality requirements, spraying methods, and processes Process, coating performance, spraying environment, time, etc.
