Chaw tsim tshuaj paus Zoo Nqe Sodium Tripolyphosphate CAS: 7758-29-4

piav qhia luv luv:

Sodium tripolyphosphate tseem hu ua pentasodium phosphate, sodium pyrometaphosphate, STPP, pentasodium tripolyphosphate.Dawb hmoov siv lead ua nrog zoo fluidity, txheeb ze molecular hnyav ntawm 367.Chemicalbook86, melting point ntawm 622 ℃, yooj yim soluble nyob rau hauv dej, thiab nws aqueous tov yog alkaline.Feem ntau siv rau hauv cov zaub mov ua tus neeg saib xyuas dej, tus neeg saib xyuas kev txhim kho zoo, pH regulator, thiab hlau chelating tus neeg sawv cev.

Sodium tripolyphosphate aqueous kua yog qaug zog alkaline (pH tus nqi ntawm 1% aqueous tov yog hais txog 9.7), thiab nws tsim ib qho kev ncua (zoo ib yam li emulsion) hauv dej nrog pH ntau ntawm 4.3-14, uas yog hu ua dispersion.Sodium tripolyphosphate kuj tuaj yeem txhim kho cov kua dej thiab cov khoom siv tshuaj lom neeg hauv cov kua (xws li dej) xov xwm, ua rau cov tshuaj pob tshab thiab zoo ib yam li cov tshuaj tiag tiag.Qhov no yog 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 ntxhua khaub ncaws ntxhua khaub ncaws.
