As we all know, because the spraying production line equipment is affected by environmental factors in the spraying process, the painting equipment gradually "oil into powder", so the powder in our country has certain rigid requirements, spraying line construction requirements you know how much?
Although the types of powder coatings are not as diverse as solvent-based coatings, there are still many polymer resins that can be used as powder coatings. Some coatings are different from traditional methods, but the requirements are the same. Now spray equipment manufacturer - Xinkaisheng to give you a look at the construction requirements of powder coating. (1) In order to give full play to the performance of the powder coating and extend the life of the coating film, the coating surface must pass the strict surface pretreatment. (2) In order to improve the spraying efficiency of powder coating, the coating must be grounded when spraying. (3) For coating with large surface defects, conductive putty should be used to ensure the flatness and smoothness of the coating film. (4) The object after spraying should be cured by heating, and the curing conditions depend on the technical indicators of the powder product, but the curing temperature and time must be fully guaranteed to avoid quality problems caused by insufficient curing
(5) Check immediately after dust removal. (6) After screening the impurities, the recovered powder should be mixed with the new powder in a certain proportion. (7) The powder supply tank, dust removal chamber and recovery system should avoid contaminating other powder of different colors, so be sure to clean up every time you change the color. With the development of society, the country pays more and more attention to the intelligent and environmental protection of the spray production line. For surface coating equipment, companies are also competing to develop the most advanced equipment to ensure both environmental protection and energy efficiency. The intelligence of the product, on this basis, the appearance of the powder supply center, solves the problem of difficult color change of the product, and greatly improves the work efficiency of the product. In the early days of spraying equipment, the powder barrel was the main part of the powder that needed to be pumped and fluidized before spraying. Can not solve the requirements of large area coating. Later, electromagnetic vibration or stirring equipment was added to the powder cylinder. With the more and more extensive use of powder coating equipment, "multi-color spraying" has become the mainstream, and the traditional powder barrel color change requires a long cleaning time, difficult color change, and the generated powder is in the process of discoloration. Therefore, under this trend of spraying coating equipment, powder supply center came into being to solve the problem of difficult color change. It uses a powerful air flow back blowing system to accurately clean the powder, save manual cleaning time, clean the powder room and pipes, and quickly change the color of the big cyclone powder room.
