Yuav siv hydroxyethyl cellulose li cas

1. Koom ncaj qha rau lub sijhawm tsim khoom

1. Ntxiv dej huv rau hauv lub thoob loj uas muaj lub tshuab ua haujlwm siab.
2. Pib nplawm tsis tu ncua ntawm qhov ceev thiab maj mam sieve cov hydroxyethyl cellulose rau hauv cov tshuaj sib npaug.
3. Txuas ntxiv stirring kom txog thaum tag nrho cov khoom yog soaked los ntawm.
4. Tom qab ntawd ntxiv cov tshuaj tua kab mob, alkaline additives xws li pigments, dispersing aids, dej ammonia.
5. Sib tov kom txog thaum tag nrho cov hydroxyethyl cellulose yog yaj tag (lub viscosity ntawm cov tshuaj tsub kom ntau) ua ntej ntxiv lwm yam nyob rau hauv cov mis, thiab grind kom txog thaum cov khoom tiav.

2. Nruab nrog niam cawv rau tos

Txoj kev no yog thawj zaug npaj cov cawv niam nrog ntau dua concentration, thiab tom qab ntawd ntxiv rau cov xim latex.Qhov kom zoo dua ntawm txoj kev no yog tias nws muaj qhov yooj yim dua thiab tuaj yeem ncaj qha ntxiv rau cov xim tiav, tab sis nws yuav tsum khaws cia kom zoo.Cov kauj ruam zoo ib yam li cov kauj ruam 1-4 hauv txoj kev 1, tshwj tsis yog tias kev nplawm siab tsis tas yuav kom yaj tag rau hauv cov kua nplaum.

3. Npaj rau hauv porridge rau kev siv

Txij li cov kuab tshuaj organic yog cov kuab tshuaj tsis zoo rau hydroxyethyl cellulose, cov kuab tshuaj organic no tuaj yeem siv los npaj cov khoom zoo li porridge.Feem ntau siv cov kuab tshuaj organic yog cov kua organic hauv cov xim pleev xim xws li ethylene glycol, propylene glycol thiab zaj duab xis qub (xws li ethylene glycol lossis diethylene glycol butyl acetate).Cov dej khov kuj yog cov kuab tshuaj tsis zoo, yog li dej khov feem ntau siv ua ke nrog cov kua dej organic los npaj cov khoom zoo li porridge.Cov khoom zoo li porridge, hydroxyethyl cellulose, tuaj yeem ncaj qha ntxiv rau cov xim, thiab hydroxyethyl cellulose tau foamed thiab o los ntawm cov porridge.Thaum ntxiv rau cov xim, nws dissolves tam sim ntawd thiab thickens.Tom qab ntxiv, nws tseem yuav tsum tau stirring kom txog thaum lub hydroxyethyl cellulose yog tag yaj thiab uniform.Feem ntau, cov khoom zoo li porridge yog tov nrog rau 6 feem ntawm cov kuab tshuaj organic lossis dej khov thiab ib feem ntawm hydroxyethyl cellulose.Tom qab li 6-30 feeb, hydroxyethyl cellulose yuav hydrolyzed thiab o pom tseeb.Nyob rau lub caij ntuj sov, cov dej kub feem ntau yog siab dhau, thiab nws tsis tsim nyog siv cov khoom zoo li porridge.
