Use 1)
Mainly used for cyanide-free electroplating, instead of so dium cyanide as a complexing agent for electroplating. It is also used as a pre-treatment agent for electroplating and pyrophosphate plating solution. Preparation of detergent components for clothing, metal surface cleaning agent and bottle cleaning agent components, additives for various cleaning agents. Used as clay dispersant in ceramic industry, dispersant and buffer for pigments and dyes. Bleaching industry is used to remove a small amount of trivalent iron ions in water to improve the quality of bleaching.
Use 2 )
In the food industry, it is used as emulsifier, tissue improver, chelating agent, and raw material for alkali water used in flour products. It is used in combination with other condensed phosphates, usually used to prevent the production of guanite in canned aquatic products and prevent the discoloration of canned fruit; Improve the expansion of ice cream, the yield of ham and sausage, and the water retention of grated fish; Improve the taste of noodles and increase the yield, prevent cheese aging and so on.
