Sodium Pyrophosphate Application:

Sodium pyrophosphate 96.5% in the electroplating industry for the preparation of plating solution, to form a network station and iron objects.

TSPP in the wool industry as a degreasing agent and hair bleaching agent.

Tetrasodium pyrophosphate in the paper industry for bleaching paper and plant fibers.

Sodium pyrophosphate industrial grade in the dyeing industry, as dyeing, bleaching, when the fine additives.

Sodium pyrophosphate anhydrous 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.

Tetrasodium pyrophosphate industrial grade in machining as a rust remover. Chemical production as a dispersant and emulsifier. Can also be used for water treatment chemicals, oil drilling, etc.

TSPP industrial grade 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, Sodium pyrophosphate can make it then dissolved and to improve cleaning ability.

In addition, Sodium pyrophosphate anhydrous 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.
