Welcome to inquire! Contact: Mr. Sha. Structural design airbrush gun powder charge must satisfy the requirements, functional design must meet the requirements of the various forms of spray painting operations and various shapes of the workpiece. Powder coating is a new surface coating process technology, based on morphology of coating powder coating process and the formation of the coating. In many occasions, instead of the traditional paint processes. At home and abroad has been widely used. Processing range including automotive parts, textile roller, printing cylinder, shoe, plastic mold, styrofoam molding, ceramic, candy and other food mold mold and electronic parts can be motivated core, decay parts, mechanical parts, industrial plating rack and scissors. Household appliances: irons, barbecue plate, bread plate, coffee maker negatives, rice cooker, hot plate, electronic accessories. Pretreatment pretreatment process quality directly affects the quality of the powder coating, spray coating pre-treatment is not good manual processing factories, causing the coating easy to fall off, bubbling phenomenon. Therefore, the first task must be stressed. For sheet metal stampings chemical pre-treatment method can be used. Ie: go to rust oil → → washing → phosphate (or purified) and so on. Most surface rust or thicker workpieces, using sandblasting, shot blasting and other mechanical methods to rust, but after a mechanical descaling should ensure that the workpiece surface is clean and can not scale. Putty. Scraping the workpiece defect extent conductive putty, sanded smooth after drying spray stainless steel cup milk processing factory, you can be the next procedure. Protection (also known as shield cover). If some parts of the workpiece does not require a coating before preheating can be covered up to protect, such as plastic spray processing factory, in order to avoid the spray paint. Preheat. Generally do not need to warm up. If a thicker coating layer is required, the workpiece can be preheated to 100 ~ 160 ℃, which can increase the coating thickness.
