How aluminum sheet painting?
4.Decorative treatment purposes: after the workpiece has reached a certain electrostatic spraying after a special appearance such as: all kinds of wood, patterns, credit and so on. Process Step: Finish; transfer and other treatment processes
3.Can be reused after sieving, the purpose of curing temperature: The surface of the powder coating is heated to a predetermined temperature and maintained appropriate time to melt, leveling, curing, thereby obtaining the surface effect we want. Process steps of: spraying a good piece pushed into the oven, heated to a predetermined temperature (usually 185 degrees), and holding the corresponding time (15 minutes); remove the furnace was cooled to obtain the finished product. Tip: heating and control systems (including electric heating, various heating oil, gas, coal, etc.) = + insulation Case curing oven
2.Adhesion, electrostatic spraying Objective: uniformly sprayed on the surface of the powder coating to the workpiece, special jobs (comprising prone to electrostatic shielding position) should be used in high-performance electrostatic spray coating machine to complete. Process steps: electrostatic adsorption principle, on the surface of the workpiece evenly sprinkled with the powder coating; powder falling through the recovery system recovering,
1.Pre-treatment purpose: to get rid of the workpiece surface oil, dust, rust and corrosion-resistant surface layer of the workpiece and can increase the spray coating adhesion "phosphate layer." The main process steps: degreasing, rust, phosphating, passivated. After pre-processing the workpiece surface is not only oil, rust, dust, and the original silver-white uniform layer of gray rough rusty phosphate coating is not easy to generate on the surface gloss, both can increase the spray rust layer
Electrostatic powder coating process principle: electrostatic powder coating spray equipment to the surface of the workpiece, in electrostatic powder evenly adsorbed on the surface of the workpiece to form a powder coating; powder coating baked at high temperatures leveling solidified into different effects (effects of different types of powder coatings) final coating; spray painting process is better than in the mechanical strength, adhesion, corrosion resistance, aging, etc., costs are also painted the same effect under.
