Metal surface paint coating process, which comprises the following steps: cleaning material, hang with, electrostatic dust, spray primer, spray coating, UV curing, UV oil matt topcoat spray coating process to do, matt UV oil is added in a high-gloss UV coating liquid oils matte powder form, the particle size in a liquid matte powder coating is 5 ~ 50μm, using a high pressure spray gun will automatically matt UV uniform coverage When the oil spray primed metal surface, by baking the liquid solvent in the paint completely evaporated to form a matte finish paint. The invention of polished metal or other material pre-treatment of low demand, the spraying of paint film formation better coverage, you can cover the surface of the sand hole metal material, scratches and other small defects appear dumb matte effect, improve yield, production through rate, while access to good corrosion resistance, abrasion resistance, scratch resistance, such as product performance. Hardware before spraying equipment, dust removal technology behind the majority of enterprises to adopt Film Dust is not satisfactory, the larger the dust content in the flue gas, solid particles of hard and sharp metal spraying plants, and suck. Lead. Exhaust fan impeller usually low-carbon steel alloy materials, good welding properties of these materials, but poor wear resistance metal spraying, some impeller run was soon wear thin and even grinding leakage, severe wear off the blade, power plants using stickers (Tu) ceramics way, but because of the impeller is in high temperature flue gas to run another shock, the ceramic material is a poor conductor of heat, a large body of material and its expansion coefficient differences, some in a very short time a large area off phenomenon Buying metal spraying process, the impeller imbalance. If welding process, will lead to deformation of the impeller, the best way is to take the wheel surface spray molybdenum alloy coating, can improve the life of more than five times the impeller, Molybdenum is a rare gold, expensive, but the price is not technically feasible Too economy.
