pretreatment line chemical washing line special for degreasing cleaning the raw aluminum roll
pretreatment line
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.Techinal Data
