Spraying processing process is an electrostatic spray coating process, used in recent years in the field of aluminum curtain wall is relatively common, asphalt coating plants, such as aluminum panels, aluminum veneer walls, Huang Jiang asphalt coating plant, spraying a high-grade coating with excellent anti-blooming, anti-fade, UV and anti-corrosion characteristics of air pollution, can withstand relatively poor weather conditions, in foreign countries have a long history of development in China started late, but more and more popular. Spraying process has two main parts, namely the pre-treatment process and spraying process: 1, pre-treatment, spraying pre-treatment process, for aluminum to oil decontamination → washing → caustic (skim) → washing → acid → washing → → washing → pure chromium water, these pre-treatment process is to make the necessary preparations for the bright spray, to ensure the smooth progress of work. 2, spraying process: spray paint primer coating → → → baking varnish coating (180-250 ℃) and curing process → quality inspection, each step requires a skilled staff skills, the spray do perfection. First processing impurities. Phosphate slag mainly caused by large particles of impurities and phosphate film yellow rust caused by small impurities into the film. And when you only need to clean the spray tank and phosphate slag accumulation in the pipeline, in proportion to control the concentration of the phosphate bath. Water impurities. Mainly the water, a small amount of sand used are salt, which had caused large impurities. Increased water filter that uses water to do for the last two stages of cleaning water. Curing oven impurities. In the wall for thorough cleaning the oven with a damp cloth and vacuum cleaner, with a focus crevice chain hanging duct. If it is a large black particulate impurities need to check the air filter is damaged at tube with the change in time. Powder impurities. Mainly powder additive excessive, uneven pigment dispersion, powder pink points by pressing cause. Improve powder quality, improved powder storage mode.
