一、概述“四合一”磷化处理是将原来的除油、去锈、磷化和钝化四道工序合并成一道,作为涂漆的前处理,以提高漆层与基体金属的结合能力,提高抗腐蚀能力。但对于油污和锈蚀特别严重的零件,在进行“四合一”磷化处理之前,仍要经过除锈和去油。

I. Overview “Four in One” phosphating is the original degreasing, rust, phosphating and passivation of the four processes merged together as a paint pretreatment to enhance the binding capacity of the paint and the base metal , Improve the anti-corrosion ability. But for the oil and rust particularly serious parts, before the “four in one” phosphating treatment, still go through the rust and oil.
