Sodium Stearate |822-16-2 : kuv
Khoom Description
Sodium stearate yog sodium ntsev ntawm stearic acid.Cov khoom dawb no yog cov xab npum tshaj plaws.Nws muaj nyob rau hauv ntau hom khoom deodorants, roj hmab, latex xim, thiab inks.Nws kuj yog ib feem ntawm qee cov khoom noj khoom haus ntxiv thiab cov khoom noj khoom haus flavorings.Txhim kho cov tshuaj soaps, sodium stearate muaj ob qho tib si hydrophilic thiab hydrophobic qhov chaw, carboxylate thiab ntev hydrocarbon saw, feem.Ob qho tshuaj sib txawv no ua rau muaj kev tsim cov micelles, uas nthuav tawm lub taub hau hydrophilic sab nraud thiab lawv cov hydrophobic (hydrocarbon) tails sab hauv, muab ib puag ncig lipophilic rau hydrophobic compounds.Cov tail ib feem dissolves cov roj (los yog) av thiab tsim cov micelle.Nws kuj yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug surfactant los pab lub solubility ntawm hydrophobic tebchaw nyob rau hauv zus tau tej cov ntau lub qhov ncauj foams.

Function & Application
Feem ntau yog siv los ua xab npum detergent.Nws yog siv los ua tus neeg sawv cev nquag thiab emulsifier ntawm cov khoom tu tus kheej.Siv los tswj ua npuas ncauj thaum yaug.(sodium stearate yog cov khoom tseem ceeb hauv xab npum)
Cov khoom no yog siv dav hauv cov khoom noj, tshuaj, tshuaj pleev ib ce, yas, hlau ua, hlau txiav, thiab lwm yam. nws kuj yog siv rau hauv acrylate roj hmab Soap / sulfur curing system.Feem ntau siv los ua emulsifier, dispersant, lubricant, deg kho tus neeg saib xyuas, corrosion inhibitor, thiab lwm yam.
1.detergent: siv los tswj cov txheej txheem foaming.Sodium stearate yog cov khoom tseem ceeb ntawm xab npum;
2.emulsifiers lossis dispersants: nruab nrab thiab nruab nrab rau polymers;
3.corrosion inhibitors: polyethylene ntim zaj duab xis los tiv thaiv kev ua haujlwm ntawm;
4. tshuaj pleev ib ce: shaving gel, pob tshab viscose, thiab lwm yam.
5.adhesive: siv raws li ntuj roj hmab paste ntawv.
