Hydroxyethyl cellulose (HEC) yog cov khoom siv dav siv nrog ntau yam kev siv thoob plaws kev lag luam.Kuj hu ua hydroxyethylcellulose los yog HEC, nws belongs rau cellulose ethers tsev neeg, muab tau los ntawm cellulose los ntawm kev hloov tshuaj.Qhov kev hloov kho no suav nrog kev qhia txog cov pab pawg hydroxyethyl mus rau cov pob txha cellulose, uas txhim kho nws cov solubility thiab lwm yam khoom siv.Thaum hydroxyethyl cellulose yog lub npe nrov, nws kuj tseem tuaj yeem raug xa mus los ntawm lwm lub npe hauv cov ntsiab lus sib txawv, nyob ntawm nws daim ntawv thov thiab kev lag luam tshwj xeeb koom nrog.
Nyob rau hauv thaj chaw ntawm chemistry thiab kev lag luam kev siv, hydroxyethyl cellulose tej zaum yuav paub los ntawm nws cov tshuaj npe, ethyl hydroxyethyl cellulose los yog tsuas yog hydroxyethylcellulose.Hauv kev lag luam thiab kev lag luam, nws yuav mus los ntawm ntau lub npe lossis cov cim lag luam, nyob ntawm cov chaw tsim khoom lossis cov neeg muag khoom.Cov npe no tuaj yeem suav nrog Natrosol, Cellosize, Bermocoll, thiab lwm yam, nyob ntawm lub tuam txhab tsim lossis faib cov khoom.
Hauv kev tsim kho thiab cov khoom siv hauv tsev, hydroxyethyl cellulose feem ntau yog siv los ua tus neeg sawv cev thickening, pab tuav dej, thiab rheology hloov kho hauv cov khoom siv cement, xws li mortar, grouts, thiab cementitious coatings.
Hauv cov chaw muag tshuaj thiab cov khoom siv kho mob tus kheej, hydroxyethyl cellulose ua cov khoom siv ntau yam nrog cov ntawv thov hauv cov qauv xws li cream, tshuaj pleev, tshuaj zawv plaub hau, thiab tshuaj kho qhov muag.Nyob rau hauv cov kev lag luam no, nws yuav raug teev nyob rau hauv cov khoom npe los ntawm nws cov tshuaj npe los yog ua ib tug thickening neeg sawv cev, stabilizer, los yog viscosity modifier.Lwm cov npe yuav suav nrog Natrosol, Cellosize, lossis tsuas yog HEC, nyob ntawm lub npe lossis cov ntawv sau npe ntawm cov chaw tsim khoom.
Hauv kev lag luam zaub mov thiab dej haus, hydroxyethyl cellulose yog siv los ua cov thickener, stabilizer, los yog emulsifier nyob rau hauv ntau yam khoom xws li kua ntses thiab hnav khaub ncaws rau dej haus thiab dej khov.Hauv cov ntsiab lus no, nws yuav raug xa mus rau tsuas yog HEC lossis los ntawm nws cov npe yog tias siv cov khoom lag luam tshwj xeeb.
thaum hydroxyethyl cellulose yog tus qauv tshuaj lub npe rau qhov sib xyaw no, nws yuav paub los ntawm ntau lub npe nyob ntawm kev lag luam, ntsiab lus, thiab daim ntawv thov tshwj xeeb.Cov npe lwm yam no tuaj yeem suav nrog cov npe lag luam, cov npe lag luam, lossis cov lus piav qhia dav dav ntawm nws txoj haujlwm lossis cov khoom.Txawm hais tias siv lub npe, hydroxyethyl cellulose tseem yog cov khoom muaj txiaj ntsig thiab muaj txiaj ntsig nrog kev siv dav hauv ntau lub lag luam.
