Kev siv ntawm HydroxyethylCellulose

Hydroxyethylcelluloseyog hu ua HEC hauv kev lag luam, thiab feem ntau muaj tsib daim ntawv thov.

1. Rau dej latex xim:

Raws li kev tiv thaiv colloid, hydroxyethylcellulose tuaj yeem siv rau hauv vinyl acetate emulsion polymerization los txhim kho kev ruaj ntseg ntawm lub polymerization system nyob rau hauv ntau yam ntawm pH qhov tseem ceeb. Hauv kev tsim cov khoom tiav, cov khoom siv ntxiv xws li pigments thiab fillers yog siv los ua kom tsis sib haum, ruaj khov thiab muab cov nyhuv thickening. Nws kuj tseem tuaj yeem siv los ua ib qho dispersant rau ncua kev kawm ntawv polymers xws li styrene, acrylate, thiab propylene. Siv rau hauv cov xim latex tuaj yeem txhim kho thickening thiab leveling kev ua tau zoo.

2. Roj drilling:

HEC yog siv los ua thickener nyob rau hauv ntau yam av nkos xav tau rau drilling, zoo chaw, cementing thiab fracturing ua hauj lwm, kom cov av nkos tau zoo fluidity thiab stability. Txhim kho cov av nkos nqa lub peev xwm thaum lub sijhawm drilling, thiab tiv thaiv kom tsis txhob muaj dej ntau los ntawm kev nkag mus rau hauv cov roj txheej los ntawm cov av nkos, stabilizing lub peev xwm ntawm cov roj txheej.

3. Rau kev tsim vaj tsev thiab khoom siv hauv tsev:

Vim nws muaj peev xwm tuav tau dej muaj zog, HEC yog cov thickener zoo thiab khi rau cov cement slurry thiab mortar. Nws tuaj yeem muab sib xyaw rau hauv mortar los txhim kho fluidity thiab kev tsim kho kev ua haujlwm, thiab tuaj yeem ua kom lub sijhawm ntev ntawm cov dej evaporation, txhim kho thawj lub zog ntawm pob zeb thiab tsis txhob tawg. Nws tuaj yeem txhim kho nws cov dej tuav thiab kev sib txuas lub zog thaum siv rau plastering plaster, bonding plaster, thiab plaster putty.

4. Siv tshuaj txhuam hniav:

Vim nws muaj zog ntsev thiab acid tsis kam, HEC tuaj yeem ua kom ruaj khov ntawm cov tshuaj txhuam hniav. Tsis tas li ntawd, cov tshuaj txhuam hniav tsis yooj yim kom qhuav vim nws cov dej ruaj khov thiab muaj peev xwm emulsifying.

5. Siv nyob rau hauv dej-raws li number case:

HEC tuaj yeem ua rau tus number case qhuav sai thiab impermeable.
