Introduction to the three basic elements of painting

There are three basic elements of coating equipment, namely coating materials, coating methods and equipment, coating technology and process management.

Excellent coatings and advanced coating equipment are the basic conditions for obtaining high-quality coatings, and are the guarantee for efficient and economical coating. However, the final quality of the coating depends on the coating process and process management to achieve.

For coatings, it is necessary not only to consider its quality and price, but also to examine its compatibility (coating and coating methods, etc.) and workability from the perspective of process and process management. If there is a problem with the compatibility of the coating or the workability is poor, there will be defects in the process, and the quality of the coating will not meet the expected requirements.

The coating equipment should not only have the characteristics of high efficiency and low price, but also have the conditions of easy operation and maintenance, safe and reliable. If the equipment operation is cumbersome and complicated, and the technical requirements are harsh, the feasibility of quality management is poor, and the coating quality is difficult to guarantee; if the equipment is poor in safety and reliability, accidents are prone to occur and the process cannot be performed normally. The problems in the coating process and process management will cause the quality of the coated workpieces to decrease, and at the same time increase the repair rate and scrap rate of the workpieces, increase operating expenses and costs, deteriorate economic benefits, and affect the normal production of products.

Therefore, to obtain a high-quality coating film on the coated workpiece, not only high-quality coatings and advanced coating equipment are required, but also reasonable technology and good process management are required to cooperate with each other. These three elements constitute The comprehensive knowledge system of coating technology system, namely coating technology (including coating characteristics and selection, coating pretreatment, coating method, coating film drying, coating process and management, etc.).
