Hydroxyethylulose (HEC) feem ntau siv los ua lub thickening thiab ruaj khov nyob hauv ntau qhov kev lag luam, suav nrog cov tshuaj pleev ib ce, tshuaj, thiab khoom siv hauv tsev. Txawm li cas los xij, nws tsis yog siv tau los ua kev noj haus ntxiv lossis khoom noj ntxiv. Thaum lub sij hawm cellulose derivatives zoo li methylcellose thiab cov carboxymethylcelleculose los yog cov zaub mov fiber ntau, HEC feem ntau tsis yog npaj rau kev noj.

Ntawm no yog ib nyuag txheej txheem ntawm HEC thiab nws siv:

1. Tus qauv tshuaj lom neeg: HEC yog semisynthetic polymer muab tau los ntawm cellulose, lub ntuj sib xyaw muaj nyob hauv cov phab ntsa ntawm tes ntawm cov nroj tsuag. Los ntawm kev hloov kho tshuaj lom neeg, hydroxyethyl pab pawg tau qhia rau lub cellulose pob txha caj qaum, ua rau cov dej-soluble polymer nrog cov khoom muaj txiaj ntsig.
2. Muaj cov ntawv thov: hauv chaw muaj kev lag luam, HEC yog muaj nuj nqis rau nws lub peev xwm los thicken thiab retchilize aqueous reds. Nws yog feem ntau siv nyob rau hauv cov khoom ntawm cov khoom siv saib xyuas tus kheej xws li cov tshuaj zawv plaub hau, tshuaj pleev, thiab cov khoom qab zib, thiab cov tshuaj nplaum, thiab xab npum.
3. Kev siv kom hniav zoo nkauj: Hauv cov tshuaj pleev ib ce, HEC pabcuam ua cov neeg sawv cev ua kom tuab, pab tsim cov khoom lag luam uas xav tau cov hom phiaj thiab viscosities. Nws tseem tuaj yeem ua raws li zaj duab xis-ua tus neeg sawv cev, ua rau muaj kev ntev thiab kev ua tau zoo ntawm cov tshuaj pleev ib ce.
4. Kws Siv Tshuaj Siv: HEC siv nyob rau hauv cov kws tshuaj tsim kho yog cov binder, dissained-tso tus neeg saib xyuas hauv ntsiav tshuaj. Nws kuj tseem tuaj yeem pom nyob rau hauv cov kev daws teeb meem ophthalmic thiab cov tshuaj pleev thiab cov gels.
5. Cov khoom siv hauv tsev: Hauv cov khoom hauv tsev, HEC tau ua haujlwm rau nws cov khoom siv tuab thiab ua kom ruaj khov. Nws tuaj yeem pom muaj nyob hauv cov khoom lag luam zoo li cov xab npum ua kua, ntxuav tais diav, tshuaj ntxuav kom huv.

Thaum HEC yog feem ntau suav tias yog kev nyab xeeb rau nws cov kev siv tsis yog cov khoom siv tsis yog cov khoom noj, nws yog qhov tseem ceeb kom nco ntsoov tias nws cov zaub mov ntxiv lossis khoom noj ntxiv. Raws li xws li, nws tsis pom zoo rau kev noj hauv cov ntsiab lus tsis muaj kev pom zoo kev cai lij choj thiab sau npe tsim nyog.

Yog tias koj txaus siab rau kev noj zaub mov noj los yog khoom noj cellulose kev xaiv, koj yuav tau siv ntau dua rau lub hom phiaj no thiab tau raug ntsuas kom muaj kev nyab xeeb hauv kev siv khoom noj.
