Daim ntawv thov ntawm hydroxyethyl cellulose

Hydroxyethyl cellulose tau raug xa mus rau raws li HEC hauv kev lag luam, thiab feem ntau muaj tsib daim ntawv thov.

1. Rau dej kua dej kom zoo:
Raws li kev tiv thaiv kev tiv thaiv, hydroxyethyl cellulose tuaj yeem siv rau hauv vinyl acetate emulsion los txhim kho cov txheej txheem polascerization hauv ntau qhov tseem ceeb ntawm p. Nyob rau hauv kev tsim cov khoom tiav, ntxiv rau xws li pigments thiab fillers yog siv los ua cov tsis sib xws, ruaj khov thiab muab cov teebmeem tuab. Nws kuj tseem siv tau los ua qhov tsis sib xws rau kev ncua kev kawm xws li styrene, acrylate, thiab propylene. Siv hauv looj cov xim yas tuaj yeem txhim kho cov tuab thiab ua tau zoo.

2. Roj Drilling:
HEC yog siv los ua cov tuab nyob hauv ntau cov av nkos yuav tsum muaj rau kev tho, ua kom cov av nkos, yog li cov av nkos tuaj yeem tau txais cov hmoov av zoo thiab ruaj khov. Txhim kho cov av nkos nqa tau thaum lub sijhawm khiav tawm, thiab tiv thaiv kom tiv thaiv kom muaj dej ntau los ntawm cov av nkos, ruaj khov cov txheej ntau lawm ntawm cov txheej roj.

3. Rau cov khoom tsim kho tsim tsev thiab lub tsev)
Vim nws lub peev xwm kav dej muaj zog, HEC yog cov tuab tuab thiab zoo siv rau Mement Slurry thiab tshuaj khib. Nws tuaj yeem sib xyaw ua pa rau hauv kev muab tshuaj khib thiab kev ua haujlwm, thiab muaj peev xwm ua kom lub zog ntev ntawm cov pob zeb ua kom tawg thiab tsis txhob tawg. Nws tuaj yeem txhim kho nws cov dej khaws cia thiab sib txuas lus lub zog thaum siv rau plastering plaster, tsev sib koom ua plaster, thiab plaster putty.

4. Siv tshuaj txhuam hniav:
Vim tias nws cov ntsev tsis kam thiab acid tiv, hec tuaj yeem ua kom cov tshuaj txhuam hniav muaj kev ruaj ntseg ntawm cov tshuaj txhuam hniav. Tsis tas li ntawd, tshuaj txhuam hniav tsis yooj yim kom qhuav vim nws txoj kev khaws cia hauv dej thiab emulsifying.

5. Siv hauv dej-ua number case:
HEC tuaj yeem ua tus mem kua mis qhuav ceev ceev thiab impminable.
