What are the main uses of sodium tripolyphosphate?

Sodium polyphosphate in the industry is mainly used as an additive for synthetic detergent, is an indispensable excellent additive, not only improve the decontamination effect of detergent, clean our living environment, while it can also be used in mining, petroleum, paper making, metallurgy and water treatment. Its main functions are as follows:

1. It has the performance of chelating hard metal ions: The washing water we usually use usually contains hard metal ions, which will react with the active substances in the detergent to form metal salts. This not only increases the amount of detergent used, but also darkens the color of the items after washing. This property of sodium tripolyphosphate can eliminate these adverse effects of metal salts.

2. Can promote gelatinization, emulsification and dispersion: sodium tripolyphosphate has a gelatinization effect on proteins in human secretions, can also promote the emulsification of fatty substances, and has a dispersion suspension effect on solid particles such as sand and dust outside.

3. It has a large alkaline buffer effect: as an auxiliary agent for synthetic detergent, sodium tripolyphosphate can maintain the PH value of detergent at about 8.4, which can promote the removal of acidic dirt.

4. Keep dry: In a high humidity environment, powdered synthetic detergent is easy to appear in a piece, which brings inconvenience during use. Sodium tripolyphosphate can form a dry hexahydrate compound after absorbing water, which can effectively prevent this phenomenon of caking, so as to maintain the dry powder synthetic detergent.
