pretreatment line

pretreatmentline can clean and chemically treat the surface of the aluminum coil.After the aluminum coil being passed,lubricant,Anti-oxidation oil and some metal elements would be left on the surface of it.Adopingthe Geman and Japanese technology,Chromium-free chemicals are used on the surface of the aluminum panel to from tiny holes for better adhesive force in order to binding the paint and the aluminum panel tightly.The production line is a environment friendly system in strict conformity with the national Enviroment standard.
