Description

Phosphate coating solution is used for material surface treatment; the dataset includes major raw materials, auxiliary materials, and energy consumed in the production process, but infrastructure such as production equipment manufacturing and facility construction is excluded from the system boundary; the life cycle inventory is compiled from data of multiple sources; the manufacturing process of phosphate coating solution includes procedures such as raw material preparation, mixing, stirring, and inspection.

Activity Description

The production process of the phosphate coating solution includes procedures such as raw material preparation, mixing, stirring, and inspection.

Process Description

The main component of the phosphate coating solution is aluminum dihydrogen phosphate, which has good adhesion to silicon steel and is conducive to forming a disordered solidified structure. This structure can more easily absorb stress and strain, thereby enhancing the coating's performance. The addition of polyether-modified silicone oil improves the surface quality of the coating and enhances the magnetic properties of the silicon steel sheets.
