Hydroxy Ethyl cellulose (HEC) qhia

Hydroxyethyl cellulose (HEC) yog dej-soluble polymer muab tau los ntawm cellulose, uas yog lub ntuj polymer pom hauv cov nroj tsuag. HEC tau synthesized los ntawm kev qhia txog cov pab pawg hydroxyethyl rau lub cellulose caj qaum los ntawm cov tshuaj lom neeg tshuaj lom neeg. Qhov kev hloov pauv no txhim kho cov dej solubility thiab lwm yam khoom ntawm cellulose, ua rau nws haum rau ntau cov ntawv thov. Ntawm no yog kev qhia rau HEC:

1. Tus qauv tshuaj: HEC khaws cov qauv ntawm cellulose, uas yog txoj kab sib txuas uas tau sib txuas nrog cov khoom qab zib uas txuas nrog los ntawm IT-1,4-glycosidic bonds. Kev qhia txog cov pab pawg hydroxyethyl (-ch2ch2oh) rau ntawm tus kab mob cellulose cais cov kua solubility thiab lwm yam khoom xav tau rau HEC.
2. Lub zog ntawm lub cev: HEC yog feem ntau muaj raws li kev nplua, dawb kom tuag dawb hmoov. Nws yog tsis muaj ntxhiab thiab tsis xis nyob. HEC yog soluble hauv dej thiab cov ntaub ntawv ntshiab, viscous daws teeb meem. Lub viscosity ntawm HEC kev daws teeb meem tuaj yeem sib txawv nyob ntawm qhov xwm txheej xws li lub polymer concentration, hnyav hnyav, thiab kub.
3. Cov Khoom Haum Ua Haujlwm: HC cov khoom ua pov thawj ntau yam khoom uas ua rau nws muaj txiaj ntsig hauv ntau cov ntawv thov:
   • Thickening: HEC yog qhov ua tau zoo tshaj plaws cov tshuab ua haujlwm zoo, condaring viscosity thiab txhim kho cov yam ntxwv ntawm cov kev daws teeb meem thiab kev tawg.
   • Dej khaws cia: HEC muaj cov khoom siv dej ua kom zoo, ua rau nws muaj txiaj ntsig zoo nyob rau hauv cov khoom uas noo noo tswj yog qhov tseem ceeb.
   • Zaj duab xis tsim: HEC tuaj yeem tsim pob tshab, cov yeeb yaj kiab hloov tau thaum ziab, cov khoom nplaum, thiab cov khoom tu tus kheej.
   • Stability: HEC tau txais kev ruaj khov thiab txee lub neej ntawm cov qauv tsim los ntawm kev tiv thaiv theem sib cais, kev ua kom tiav, thiab synergeses.
   • Kev sib txuam: Hec yog sib xws nrog ntau cov khoom xyaw, suav nrog sals, acids, thiab surfactants, cia rau kev tsim qauv yoog thiab versatility.
4. Cov ntawv thov: HEC pom pom ntau yam kev lag luam, suav nrog:
   • Kev tsim kho: Siv cov khoom siv cov paj ntaub xws li mortars, gutsws, thiab cov ris tsho, thiab cov neeg sawv cev, thiab rheology kho tshuab.
   • Xim thiab pleev xim: siv los ua cov tuab, stabilizer, thiab rheology kho hauv cov xim tsev, pleev xim, thiab cov nplaum.
   • Cov khoom siv saib xyuas tus kheej: pom nyob rau hauv cov tshuaj zawv plaub hau, cream, cream, pelsions, thiab gels, stabilizer, thiab zaj duab xis yav tas los.
   • Kws muag tshuaj: siv los ua phau ntawv cog lus, thiab viscosity concorifier hauv ntsiav tshuaj, tsiav tshuaj, thiab kev ncua.
   • Kev lag luam khoom noj: siv los ua cov thickener, stabilizer, thiab emulsifier hauv cov khoom noj khoom noj xws li cov kua ntses, cov kua zaub, thiab khoom noj siv mis.

Hydroxyethyl cellulose (HEC) yog ib qho kev siv ntau yam thoob plaws hauv kev lag luam, uas nws muaj kev ruaj khov, thiab ua haujlwm ntawm ntau cov khoom lag luam thiab cov qauv.
