Sodium polyphosphate in industry mainly used as synthetic detergent auxiliaries is an indispensable assistant, excellent, not only improves the detergent decontamination effect, clean our living environment, and at the same time, it can also be used in mining, petroleum, metallurgy, papermaking and water treatment etc.. Its main function has the following several points:
1 has the properties of chelating metal ion induced hard: in the washing water, we usually use usually contain to hard metal ions, they will react with the active substances in detergents, forming a metal salt. In this way not only increased the amount of detergent used, also will make after washing articles dark. The performance of sodium tripolyphosphate can eliminate the negative impacts brought about by the metal salt.
2 can promote the glue solution, emulsifying and dispersing: sodium tripolyphosphate with peptization effect on the human body secretions in the protein, can promote fatty substance emulsion, on the outside of the sand dust and other solid particles are dispersed suspension effect.
3 with alkaline buffer larger effect: as the synthetic detergent additives, sodium tripolyphosphate can make the detergent pH maintained at about 8.4, which can promote the removal of acidic dirt.
4: keep dry in a high humidity environment, synthetic detergent powder is easy to appear the piece, which in the process of use inconvenience. Sodium tripolyphosphate can form six water combination product dry after water absorption, it can effectively prevent the phenomenon of agglomeration, thus keeping the synthetic detergent powder dry.
