Hydroxyethyl cellulose (HEC) yog cov khoom siv dej-soluble polymer ua los ntawm cov xov tooj ntawm lub ntsej muag los ntawm Eetherification hloov kho. Vim nws cov tuab heev, ncua, emulsification, zaj duab xis, cov khoom noj khoom haus, cov ntaub qhwv, cov textiles, papiles, papermaking thiab lwm daim teb.
1. Thickening thiab rheology tswj
1.1 thickening muaj peev xwm
HEC muaj kev muaj peev xwm hnyav dua thiab tuaj yeem tsim cov kev ntxhov siab viscosity hauv dej. Cov cuab yeej no tso cai rau nws kom nce cov viscosity thiab sib xws ntawm cov khoom. Piv txwv li, hauv txheej kev lag luam, HEC muaj peev xwm ua kom cov viscings kom zoo ntxiv, yog li kev hloov pauv ntawm txhuam thiab tshem tawm; Hauv cov tshuaj pleev ib ce, nws tuaj yeem muab cov tshuaj ntxuav kom haum rau xab npum, tshuaj zawv plaub hau thiab lwm yam khoom los txhim kho kev siv.
1.2 rheology kho
HEC tuaj yeem hloov kho cov rheology ntawm cov kua dej, uas yog, ntws thiab deformation tus cwj pwm. Nyob rau hauv oilfield ntau lawm, hec yog siv los tswj cov rheology ntawm drilling kua dej, txhim kho lawv cov roj xuab zeb, thiab ua kom zoo rau cov roj thiab roj ntau txheej txheem. Hauv kev lag luam papermaking, HEC tau hloov cov fluidity ntawm cov txheej txheej ua kua, kom ntseeg tau tias cov txheej txheem zoo nkauj, thiab txhim kho cov ntawv ci thiab du ntawm daim ntawv.
2. Kev ruaj khov thiab ncua sijhawm
2.1 Levitation Muaj Peev Xwm
HEC muaj kev kawm tau zoo heev thiab tuaj yeem tiv thaiv cov khoom seem los ntawm cov kua. Qhov no yog qhov tshwj xeeb tshaj yog rau cov qauv muaj cov khoom muaj. Piv txwv li, hauv cov xim tha xim, HEC muaj peev xwm ncua tsis pub ncua cov xim thiab tiv thaiv lawv los ntawm kev sib sau thaum lub sijhawm cia, yog li ua kom muaj kev sib luag thiab ruaj khov ntawm cov xim. Hauv cov qauv tshuaj tua kab, HEC tuaj yeem ncua kev noj tshuaj thiab txhim kho lawv cov kev tsis txaus siab thaum nqus.
2.2 ruaj khov
HEC muaj tshuaj lom neeg zoo tshaj li qhov kub thiab txias thiab tsis yooj yim los yog decomposed. Lub plawv no tso cai rau HEC kom tswj nws qhov kev ua tau zoo nyob hauv ntau yam kev mob hnyav. Piv txwv li, hauv cov ntaub ntawv tsim kho, HEC tuaj yeem ua rau muaj kev vam meej hauv cov dej ua kom tiav thiab ua kom muaj zog ntawm cov neeg muaj nyiaj txiag thiab mortars.
3. Moisturizing thiab zaj duab xis-ua cov khoom
3.1 Muaj peev xwm muaj peev xwm ya ua
HEC muaj cov peev xwm moisturizing tseem ceeb, kev ntes thiab khaws cia noo noo hauv cov khoom. Qhov no ua rau nws muaj cov tshuaj zoo tshaj plaws hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej. Piv txwv li, hauv cov moisturizing lotions thiab ntsej muag lub ntsej muag, HEC tuaj yeem pab kaw hauv daim tawv nqaij noo, muab cov kev cuam tshuam ntev ntev, thiab txhim kho cov khoom muaj kev nplij siab.
3.2 Zaj duab xis-tsim cov khoom
HEC tuaj yeem tsim qhov pob tshab, zaj duab xis tawv tom qab dej yaj. Cov cuab yeej ua yeeb yaj kiab no ua rau HEC dav siv hauv cov tsho tiv no, tshuaj pleev ib ce, ci ntsa iab thiab lwm thaj teb. Piv txwv li, hauv cov chaw muag tshuaj, HEC tuaj yeem siv los ua cov khoom siv txheej ua cov tshuaj tso tawm thiab txhim kho kev ruaj ntseg ntawm cov tshuaj siv tshuaj. Hauv cov tshuaj pleev ib ce, HEC tuaj yeem siv los ua ib qho ntawm cov plaub hau gel los ua cov yeeb yaj kiab tiv thaiv thiab txhim kho cov nyhuv styling.
4. BiCompatibility thiab kev tiv thaiv ib puag ncig
4.1 biocompatibility
Txij li thaum HEC yog muab tau los ntawm cov cellulose ntuj, nws muaj zoo biocompatibility thiab tsawg toxicity. Yog li, HEC tau siv dav hauv cov qauv ntawm cov tshuaj thiab cov khoom noj. Piv txwv li, hauv cov tshuaj, HEC feem ntau siv los ua phau ntawv thiab ua txhaum cai kom ntseeg tau tias muaj cov ntsiav tshuaj nyab xeeb thiab kev nqus cov ntsiav tshuaj hauv lub cev; Hauv kev lag luam khoom noj khoom haus, HEC tuaj yeem siv los ua cov tuab thiab muaj stabilizer, uas yog muaj kev nyab xeeb heev thiab tsis muaj tshuaj lom. Sab nyhuv.
4.2 Kev tiv thaiv ib puag ncig
HEC yog cov khoom siv biodegradable uas ua rau ib puag ncig ib puag ncig uas tsis muaj kuab paug. Piv nrog qee cov hluavtaws thickeners, HEC muaj tsawg txoj kev cuam tshuam ib puag ncig tom qab siv tom qab siv thiab yog vim li ntawd ib puag ncig tus phooj ywg ntxiv. Piv txwv li, hauv daim ntawv thiab textile Industries, kev siv HEC tuaj yeem txo cov pa phem thiab ua tau raws li kev tsim khoom ntsuab.
5. Yooj yim ntawm kev ua thiab muaj ntau yam kev siv
5.1 solubility
Hec Dissolves yooj yim nyob rau hauv dej txias, sib sau cov pob tshab thiab cov kev sib dhos colloidal tov. Piv nrog qee lwm qhov thickeners, HEC tsis tas yuav muaj cov xwm txheej nyuaj tshaj plaws, uas ua rau nws siv hauv kev tsim khoom yooj yim heev.
