pretreatment line

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
