The use of sodium pyrophosphate

The electroplating industry is used to prepare electroplating solutions, which can form complexes with iron. Wool spinning industry is used as a wool degreaser and bleaching agent. The papermaking industry is used for bleaching paper and plant fibers. The printing and dyeing industry is used as an auxiliary agent for printing, dyeing, and fine bleaching. The daily chemical industry is used as a toothpaste additive, which can form colloids with calcium hydrogen phosphate and have a stabilizing effect. It can also be used to synthesize detergents and produce products such as shampoo. Used as a water softener in water treatment. Used as a rust remover in mechanical processing. Used as a dispersant and emulsifier in chemical production. It can also be used as a water treatment agent, oil drilling, etc., and as a quality improvement agent, emulsifier, buffer, chelating agent, etc. in the food industry.

In addition to its ability to soften water, sodium pyrophosphate can also dissolve insoluble salts of calcium and magnesium, such as dirt formed by insoluble calcium soap or other metal soaps mixed in clothing fibers. It can dissolve them again and improve their cleaning ability. In addition, sodium pyrophosphate has an anti flocculation effect, causing oil to emulsify, which is called gelatinous properties. It can also further reduce the surface tension and interfacial tension of the surfactant solution, serving as a washing aid
