Do you know what pearl black electrophoresis aluminum profile is? It is coating a layer of transparent electrophoretic paint on the surface of the pure black aluminum profile product to make it as bright as a black pearl. Aluminum black pearls with good color and no particles on the surface, smooth and beautiful that favored by all users.
The raw material in the production process of pearl black aluminum profile is the aluminum profile after extrusion and artificial aging treatment. In the pretreatment, using an AC acid degreasing agent, alkali washing, and sulfuric acid neutralization. Oxidized and colored by sulfuric acid anodization and single nickel salt electrolysis.
The electrophoretic coating is an important process to make the pearl black profile shine or not. The first step is to stabilize the composition of the tank, such as solid content, electrical conductivity, amine molar ratio, and PH. At the same time, we must ensure that the film thickness is appropriate, the thickness is too high and easy to produce orange peel, the thickness is low and dull, and generally should be controlled at 7 ~ 9μm appropriate. In addition, the voltage should not be too high, the pinhole visual sense of pure black surface paint film is easy to enlarge, so the voltage is lower than champagne and bronzer, control in 70 ~ 80V is appropriate.
Because the surface of the pearl black electrophoresis aluminum profile has special mirror refraction, wearing gloves is necessary while inspecting and packaging. Otherwise, it is easy to leave fingerprints, although erasable but will affect the product's surface appearance luster effect.
