powder coating for different field

Powder coating construction (1) for the characteristics of the powder coating can into full play and prolong the service life of the coating and is coated on the surface of first strictly before surface treatment (2) spraying, coating shall be fully grounded to increase powder coating spraying efficiency. (3) the larger surface defects of the object to be coated should be scraping conductive putty, to ensure smooth film and smooth sense (4) after spraying, object, objects, the need for heating and curing, curing conditions to powder product specifications but must be fully guaranteed the curing temperature and time, avoid the quality accidents caused by lack of cure. (5) powder, after the check immediately, if defects are found should be handled in a timely manner, if after curing defects are found, the scope of small locally only and does not affect the, was painted surface decoration, available with the color of powder and acetone diluted repair, if range and affect the quality of the surface is polished with sandpaper, spraying a or paint stripper to remove coating, re shenai powder. (6) the recovered powder shall be filtered to remove impurities, and then mixed with the new powder in a certain proportion. (7) for powder barrels, dusting rooms and recovery system should be to avoid contamination of the powder of different colors, so every time when change the colors must be clean, purge. Classification standard, the name of various types of powder on the market is uneven.

According to the properties of the film forming material is divided into two categories: powder coating (PE) and thermosetting powder coating. Or the appearance of film forming material is divided into: extinction type, high light type, art type, etc.. You can also press the use of the environment is divided into indoor and outdoor two categories. Powder coating is a kind of powder coating which can withstand more than 200 degrees Celsius for a long time, and the coating is good, and can make the object to be protected in the high temperature environment. Experiments show that using silicone resin can make the heat resistance of powder coatings significantly increased (service life from the original 300 DEG C for 1 h, increased to more than 70h), which can satisfy the long-term use in 350 DEG C and coating has good adhesion and resistance, impact resistance and flexibility of the available for the engine and 

the exhaust pipe of heat resistant coatings.
