Coating technology

Coating technology is a general term for the process or technology of removing coatings on the prepared substrate to form uniform, continuous, firmly adhered coatings with various corrosion resistance or functions. It is widely used in decoration, protection and various functions, especially in preventing atmospheric corrosion, which accounts for more than 2/3 of the total funds for metal corrosion and protection. Obviously, the structure design and surface state of the substrate to be coated must meet the technical requirements of the corresponding coating. The coatings to be selected not only can be coated to meet the performance requirements of the coating film, but also adapt to the substrate to be coated, and to adapt to the coating method to be used. Only in this way can the anticipated decoration, protection and various functions be achieved.

As mentioned above, it is not difficult to see that painting is a systematic engineering. It covers the structural design of the coating matrix, the surface preparation of the coating surface, the selection of appropriate coatings and the design of the corresponding coating system, the coating of coatings and the selection of the corresponding coating technology, as well as the post-treatment of the coating. One of these links should not be treated in isolation. Only if the previous link succeeds, can the follow-up process be guaranteed not to fail. Only by linking the links one by one, one by one, and one by one, can the links be reasonably and appropriately linked, and the links be appropriately tightly linked, can a strict system be formed. In fact, this is the key of ISO9000 quality assurance system, and the quality of every link, every process or every process is the fundamental guarantee of the quality of the whole loop system and the whole process. The failure of the preceding link or process will inevitably result in the failure of the whole process, which will result in great waste.

In the past, only attention was paid to the specific coating process, and only attention was paid to the selection of the best paint possible, while neglecting surface preparation and post-treatment, which often resulted in twice the effort. According to the statistics of many experts, 75% of the unsuccessful or unsuccessful painting results from improper pretreatment and inappropriate initial process, so that the follow-up process is completely useless even if it is ideal.
