Zinc sulfate is an essential raw material for surface treatment processes, widely used in three mainstream processes: galvanizing, zinc phosphating and passivation. It is one of the fundamental materials that guarantee coating quality, corrosion resistance and production stability.
In electrogalvanizing, high-purity zinc sulfate steadily supplies zinc ions with consistent composition and controllable purity, laying the foundation for coating crystallization. It helps form a uniform, dense and smooth zinc coating, delivering stable zinc ions to ensure good appearance and long-term anti-corrosion performance of workpieces. Coating quality is affected by multiple factors including main salt concentration, additives, current density, pH value, temperature and agitation, among which zinc sulfate is a critical raw material.
For zinc phosphating, the key film-forming substance of phosphating solution is zinc dihydrogen phosphate (or zinc phosphate salts). As an important co...
