Chaw Tsim Khoom Zoo Tus Nqi Sodium Tripolyphosphate CAS: 7758-29-4

piav qhia luv luv:

Sodium tripolyphosphate tseem hu ua pentasodium phosphate, sodium pyrometaphosphate, STPP, pentasodium tripolyphosphate. Dawb siv lead ua hmoov nrog cov kua dej zoo, qhov hnyav molecular ntawm 367.Chemicalbook86, melting point ntawm 622 ℃, yooj yim soluble hauv dej, thiab nws cov kua dej yog alkaline. Feem ntau siv rau hauv cov khoom noj ua tus neeg sawv cev khaws dej, tus neeg sawv cev txhim kho zoo, pH regulator, thiab tus neeg sawv cev hlau chelating.

Cov kua dej Sodium tripolyphosphate yog cov alkaline tsis muaj zog (tus nqi pH ntawm 1% cov kua dej yog li 9.7), thiab nws tsim cov tshuaj ncua (zoo ib yam li emulsion) hauv dej nrog pH ntau ntawm 4.3-14, uas hu ua dispersion. Sodium tripolyphosphate kuj tseem tuaj yeem txhim kho qhov solubility ntawm cov kua thiab cov khoom siv tshuaj hauv cov kua (xws li dej), ua rau cov tshuaj pob tshab tag nrho thiab zoo li cov tshuaj tiag tiag. Qhov no hu ua solubilization. Vim nws cov khoom tshwj xeeb, sodium tripolyphosphate tau dhau los ua cov khoom siv tseem ceeb thiab zoo tagnrho hauv cov tshuaj ntxhua khaub ncaws.
