powder coating is a rapidly developing field in the entire coating technology. To realize the popularization and application of low-temperature powder coatings in automobile wheels, the premise is that the wheel products produced under the low-temperature powder process meet the current performance standards of automobile parts. Automobile wheels are the main load-bearing parts of automobiles, which not only require sufficient mechanical strength, but also sufficient toughness to ensure impact resistance.However, the curing conditions of ordinary powder coatings are mostly around 180℃, and some are as high as 200℃, and the time is about 25min. First, the realization mechanism of low-temperat...

Temperature adjustment * curing temperature, and make the ruing time of the conveyor belt in the oven match the curing time, taking into account the drop in the temperature of the inlet and outlet of the oven and the difference between the actual working temperature and the oven instrument temperature, the director can be flexible 10-20 % Of the ruing time or increase 5-10℃2, start the air compressor, randomly check a part of the powder coating, insert the powder suction tube of the spray gun into the powder container, adjust the working voltage to 40,000-80,000 volts, and the air is too high.Powder coating usage conditions: Static value: 40-80kv Film thickness: 60-70U (lower limit: 50U uppe...

The appearance generates a stable maintenance layer, but when using silicone resin alone, the intermolecular force is relatively small, the adhesion is poor, and the price is relatively high. Silicone resin is an indispensable base material for high temperature resistant powder coatings.Due to their higher bond energy, silicone resins have higher oxidation stability and can be used in coatings. High temperature resistant special resin and high temperature resistant pigments and fillers form high temperature resistant plastic powder, which is commonly used for spray coating on the surface of ovens, guardrails, automobile brake pads and exhaust pipes.Because of their high temperature resistanc...
