Potassium pyrophosphate application:
Mainly used for cyanide-free electroplating, replacing sodium cyanide as the complexing agent for electroplating. Also used as pre-treatment agent for electroplating and pyrophosphate plating solution. Preparation of detergent components for clothing, components of metal surface cleaners and bottle cleaners, and additives for various detergents. Used as a clay dispersant in the ceramic industry, a dispersant and buffer for pigments and dyes. In the bleaching and dyeing industry, it is used to remove a small amount of ferric ions in water to improve the quality of bleaching and dyeing.
Packaging and Shipping
