Hydroxyethylcellulose (HEC) yog nonionic soluble cellulose ether dav siv nyob rau hauv ntau yam lag luam. HEC yog muab los ntawm ntuj cellulose thiab hloov kho kom muaj hydroxyethyl pawg ntawm cov pob txha cellulose. Qhov kev hloov kho no ua rau HEC soluble nyob rau hauv dej thiab lwm yam polar solvents, ua rau nws zoo tagnrho polymer rau ntau yam kev siv.
Ib qho ntawm cov kev siv tseem ceeb ntawm HEC yog ua cov thickener thiab nplaum nyob rau hauv ntau yam khoom siv thiab kev lag luam. HEC feem ntau yog siv rau hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej xws li tshuaj zawv plaub hau, tshuaj pleev thiab tshuaj txhuam hniav kom muaj viscosity thiab ruaj khov. Nws kuj yog siv rau hauv cov xim, coatings thiab adhesives los muab cov khoom nplaum thiab txhim kho kev ya raws.
HEC yog lub tsev thaiv ntau yam rau cov khoom siv no vim tias nws muaj peev xwm nce viscosity hauv cov dej-raws li cov tshuab tsis muaj kev cuam tshuam rau lwm yam khoom. Los ntawm kev ntxiv HEC rau cov khoom no, cov tuam txhab tsim khoom tuaj yeem kho qhov tuab, kev ntxhib los mos thiab sib xws ntawm lawv cov khoom kom tau raws li cov neeg siv khoom nyiam thiab cov kev xav tau ntawm kev lag luam.
Lwm daim ntawv thov tseem ceeb ntawm HEC yog hauv kev lag luam kws tshuaj. HEC yog ib qho khoom muaj nyob rau hauv ntau yam khoom siv tshuaj, nrog rau cov ntsiav tshuaj, tshuaj ntsiav, thiab tshuaj xa cov tshuab. Vim lawv muaj peev xwm hloov kho cov rheology thiab o ntawm cov ntaub ntawv ntau npaum, HEC tuaj yeem txhim kho bioavailability ntawm cov khoom xyaw nquag thiab txhim kho kev tswj cov tshuaj tso tawm. HEC kuj tseem siv los txhim kho kev ruaj ntseg ntawm emulsions thiab tshem tawm hauv cov tshuaj formulations.
Hauv kev lag luam khoom noj khoom haus, HEC yog siv los ua cov thickener thiab stabilizer nyob rau hauv ntau yam khoom noj khoom haus, nrog rau cov kua ntses, hnav khaub ncaws thiab cov khoom siv mis nyuj. HEC yog ib qho kev nyab xeeb, cov khoom xyaw ntuj pom zoo siv rau hauv cov zaub mov los ntawm cov koom haum tswj hwm thoob ntiaj teb. Nws kuj yog siv los ua cov rog hloov hauv cov khoom noj muaj roj tsawg, muab cov kev ntxhib los mos zoo sib xws thiab lub qhov ncauj zoo rau cov khoom muaj rog.
HEC kuj tseem siv rau hauv kev tsim kho kev lag luam ua cov thickener thiab binder hauv cov khoom cementitious xws li grouts, mortars thiab adhesives. Cov khoom thixotropic ntawm HEC ua rau nws muaj cov khoom xyaw zoo tshaj plaws rau cov khoom no, tso cai rau lawv nyob hauv qhov chaw thiab tiv thaiv sagging lossis teeb meem. HEC muaj adhesion zoo dua thiab dej tsis kam, ua rau nws yog ib qho tseem ceeb muaj nyob rau hauv waterproofing thiab sealing khoom.
Hydroxyethyl cellulose yog non-ionic soluble cellulose ether nrog ntau yam kev siv hauv ntau yam lag luam. HEC yog cov khoom siv ntau yam thiab tseem ceeb hauv ntau cov neeg siv khoom thiab cov khoom lag luam, muab kev ruaj ntseg, viscosity, thiab kev tswj cov tshuaj tso tawm. HEC yog cov khoom xyaw ntuj, nyab xeeb thiab ib puag ncig zoo uas tau pom zoo siv los ntawm ntau lub tebchaws thoob ntiaj teb. Nws cov khoom tshwj xeeb thiab ntau yam ua rau HEC yog ib qho tseem ceeb hauv ntau cov khoom thiab kev lag luam.
