Sodium pyrophosphate-7722-88-5 purposes:
7722-88-5 in the electroplating industry for the preparation of plating solution, to form a network station and iron objects. 7722-88-5 wool in the wool industry as a degreasing agent and hair bleaching agent. 7722-88-5 in the paper industry for bleaching paper and plant fibers. 7722-88-5 in the dyeing industry, as dyeing, bleaching, when the fine additives. 7722-88-5 toothpaste additive used in the Japanese chemical industry, with the formation of dicalcium phosphate gel and play a stabilizing role, can also be used for production of synthetic detergent shampoo and ointment products. 7722-88-5 in machining as a rust remover. Chemical production as a dispersant and emulsifier. Can also be used for water treatment chemicals, oil drilling, etc.,7722 -88-5 in the food industry as a quality improver, emulsifier, buffer, chelating agents and so on.
7722-88-5 has softened the features, can be dissolved calcium and magnesium insoluble salts, such as clothing fibers, mixed live insoluble calcium soap or metal soap formation of dirt,7722 -88-5 can make it then dissolved and to improve cleaning ability. In addition,7722 -88-5 have anti-flocculation, so that oil from the emulsion, which is called peptization nature. Surfactant solution can also further reduce the surface tension and interfacial tension, play a role in washing to help wash.
