For the first time deep cleaning, the cleaning aluminum coating, pretreatment, electrophoresis tank before the vote is a priority, especially electrophoresis tank, if inadequately cleaned, it may cause electrophoresis shrinkage, and shrinkage will once formed a long not cure period of time. General chemical cleaning procedure is: after the device cleaned, all the slots are filled with water, sprayed aluminum prices, circulation more than 24h; then put water emissions, into 0.l ~ 0.5% of degreasing agents, cleaning cycle, aluminum spraying process, can be heated in the tank is heated to clean more than 8h, aluminum spraying process, before it is discharged; rinse, plus washed clean. After pretreatment table transfer the slots, after washing with deionized water cycle, generally speaking it. 3. In addition to electricity and dust: plastic is an insulator, the surface resistance is generally about 1013Ω, easy to produce static electricity. After easily absorbed charged fine dust in the air and deposited on the surface. Dust due to electrostatic adsorption removed by blowing very difficult in general, the use of high pressure ionized air flow at the same time better effect in addition to ESP. 4. Spray: plastic coating thickness of 15 ~ 20μm, usually 2 to 3 spraying to complete. After spraying a dry 15min, and then a second coating. Need bright surface must also sprayed clearcoat. After the coated article substantially no effect on flame retardancy.
