1, before processing purposes: to remove surface oil, dirt, rust, and corrosion-resistant surface layer of the workpiece and can increase the spray coating adhesion "phosphate layer" or "chromium layer." The main process steps: degreasing, descaling, phosphate (chromium), passivation. After the pre-treatment of the workpiece surface is not only oil, rust, dust, and original silver-white to generate a uniform layer on the surface of the shiny and rough gray phosphate coating is not easy to rust (chromium film), both anti-rust again spray can increase the adhesion layer. Common pre-treatment have immersion, spray, waterfall three coating machinery, immersion require multiple soaking groove; you need to set some spray sprinkler line on the coating line; a solution directly from a waterfall along the workpiece height shed. 2, electrostatic spraying purposes: powder coating evenly sprayed onto the surface of the workpiece, special artifacts (including static shielding prone position) should be high-performance electrostatic spray coating machine to complete. Process steps: electrostatic adsorption principle, on the surface of the workpiece a uniform layer of powder spray coating; powder falling through the recovery system recovering, after sieving can then 3, the cured object: after curing the powder coating to the surface of the workpiece . Process steps; As the workpiece after spraying high temperature of about 200 ℃ furnace 20 minutes (curing temperature and time depending on the selected quality may be a powder, a special low-temperature curing temperature of the powder is about 160 ℃, more energy saving), the powder concentration finance, leveling, cured. Qu Sino Painting Equipment Co., Ltd. has strong technical force and production strength, and has a good after-sales service team, the series of product design, reasonable structure, stable performance. Is recommended in light of product quality protection center for "high-quality light industrial products, satisfied with the quality brand" of the title. I draw upon the advantages of similar foreign products, innovation, over the years to high standards and quality for domestic customers trying to sacrifice quality, inexpensive variety of coating equipment painting, praised by users. Power user needs is constantly open up business, we have the spirit of "customer first" purpose, quality manufacturing services to the public. And implementation of turnkey engineering services. Electrostatic powder coating spray equipment to the surface of the workpiece, in electrostatic powder evenly adsorbed on the surface of the painting company, to form a powder coating; powdery coating cured at high temperatures baking leveling, varying results become final coating; spray painting process is better than the mechanical strength, adhesion, corrosion resistance, anti-aging and so on. One. Surface preparation. Pre-treatment process quality directly affects the quality of the powder coating, pre-treatment is not good, causing the coating easy to fall off, bubbling phenomenon. Therefore, the first task must be stressed. (1) can be used for sheet metal stampings chemical pre-treatment method. 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 coating machine, but after a mechanical descaling should ensure that the workpiece surface clean and free of dirt. (2) putty. Scraping the workpiece defect extent conductive putty, sanded smooth after drying, you can be the next procedure. (3) 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 glue, etc., in order to avoid the spray paint. (4) to warm up. 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. Electrophoretic coating, painting, painting equipment provided by Sino Sino Painting Equipment Co. Qu. Qu Sino Painting Equipment Co. (www.wfjn.com) (www.wfjn.com) (www.wftcsw.com) strong, credible, Shandong Weifang industrial automation control systems and equipment industry has accumulated a large number of loyal customers.
