Purpose

Tetrapotassium Pyrophosphate is Agricultural Grade Phosphate and Tech Grade Phosphate Mainly used for cyanide-free electroplating, replacing sodium cyanide as a complexing agent for electroplating. It is also used as a pretreatment agent for electroplating and as a pyrophosphate electroplating solution. Preparation of laundry detergent components, metal surface cleaning agents and bottle cleaning agent components, various detergent additives. Used as a clay dispersant, dispersant and buffer for pigments and dyes in the ceramic industry. The bleaching and dyeing industry is used to remove small amounts of trivalent iron ions from water and improve the quality of bleaching and dyeing. Potassium pyrophosphate is also an excellent stabilizer for hydrogen peroxide. In the food industry, it is used as an emulsifier, tissue modifier, chelating agent, and also as a raw material for alkaline water used in flour products. It is commonly used in combination with other condensed phosphates to prevent the formation of guanosine in canned aquatic products and prevent the discoloration of canned fruits; Improve the expansion of ice cream, the yield of ham and sausage, and the water holding capacity of ground fish; Improve the taste and yield of noodles, prevent cheese aging, etc. Potassium pyrophosphate can also be used as a complexing agent for alkaline electroless nickel plating and in the preparation of detergents.
