PA-3: a multifunctional cleaning agent, which can quickly clean rust and scale on the surface of the workpiece, and can form a protective film on the surface of the workpiece with a certain antirust function Because acid liquor is easy to remain in the interlayer or gap, even after phosphating treatment, the crack is still easy to return to rust. However, PA-3 can solve this problem well, and a protective film can be formed at the same time of pickling and rust removal, which can play a protective role.
