Cellulose, Hydroxyethyl Ether (MW 1000000)

Hydroxyethyl cellulose(HEC) yog cov dej-soluble polymer muab tau los ntawm cellulose los ntawm kev qhia ntawm hydroxyethyl pawg. Qhov hnyav molecular (MW) tau teev tseg, 1000000, sawv cev rau qhov sib txawv ntawm qhov hnyav molecular. Ntawm no yog ib qho piv txwv ntawm hydroxyethyl cellulose nrog ib qho hnyav molecular ntawm 1000000:

Hydroxyethyl Cellulose (HEC):

1. Chemical Structure:
   • HEC yog ib qho cellulose derivative uas cov pab pawg hydroxyethyl txuas mus rau anhydroglucose units ntawm cellulose saw. Qhov kev hloov kho no txhim kho cov dej solubility thiab lwm yam kev ua haujlwm ntawm cellulose.
2. Molecular Luj:
   • Qhov ntsuas molecular hnyav ntawm 1000000 qhia tias muaj qhov hnyav molecular ntau yam. Molecular hnyav cuam tshuam rau viscosity, rheological zog, thiab kev ua haujlwm ntawm HEC hauv ntau daim ntawv thov.
3. Daim ntawv lub cev:
   • Hydroxyethyl cellulose nrog lub luj molecular ntawm 1000000 feem ntau muaj nyob rau hauv daim ntawv ntawm ib tug dawb mus rau dawb, tsis muaj ntxhiab hmoov. Nws kuj tseem tuaj yeem muab tau los ua kua dej lossis dispersion.
4. Dej Solubility:
   • HEC yog dej-soluble thiab tuaj yeem tsim cov kua dej ntshiab thiab khov kho hauv dej. Lub degree ntawm solubility thiab viscosity tuaj yeem cuam tshuam los ntawm cov khoom xws li kub, pH, thiab concentration.
5. Daim ntawv thov:
   • Thickening Agent: HEC feem ntau yog siv los ua tus neeg sawv cev thickening hauv ntau daim ntawv thov, suav nrog cov xim, txheej, nplaum, thiab cov khoom tu tus kheej. Lub siab molecular hnyav variant yog tshwj xeeb tshaj yog zoo nyob rau hauv muab viscosity.
   • Stabilizer: Nws ua haujlwm zoo li stabilizer hauv emulsions thiab tshem tawm, ua rau muaj kev ruaj ntseg thiab sib xws ntawm cov formulations.
   • Dej Retention Agent: HEC muaj cov khoom tuav dej zoo heev, ua rau nws muaj txiaj ntsig zoo hauv cov khoom siv, xws li mortars thiab cement-based khoom.
   • Pharmaceuticals: Hauv kev lag luam kws tshuaj, HEC yog siv los ua cov ntawv khi, disintegrant, thiab thickener hauv cov tshuaj ntsiav tshuaj. Nws cov dej-soluble xwm ua rau nws haum rau ntau hom ntawm qhov ncauj.
   • Cov Khoom Siv Kho Tus Kheej: Pom muaj nyob rau hauv cov tshuaj pleev ib ce, tshuaj zawv plaub hau, thiab tshuaj pleev ib ce, HEC muab viscosity thiab ruaj khov rau cov qauv hauv kev lag luam tu tus kheej.
   • Roj thiab Roj Kev Lag Luam: HEC yog siv rau hauv cov kua dej drilling raws li kev hloov kho rheology thiab tus neeg saib xyuas cov dej tsis zoo.
6. viscosity tswj:
   • Lub siab molecular hnyav ntawm HEC pab txhawb rau nws cov hauj lwm zoo hauv kev tswj viscosity. Cov cuab yeej no muaj txiaj ntsig zoo hauv cov ntawv thov uas xav tau thickness lossis ntws cov yam ntxwv ntawm cov khoom yuav tsum tau khaws cia.
7. Compatibility:
   • HEC feem ntau sib xws nrog ntau yam ntawm lwm cov ntaub ntawv thiab cov khoom siv ntxiv uas feem ntau siv hauv kev lag luam sib txawv. Txawm li cas los xij, kev ntsuas kev sib raug zoo yuav tsum tau ua thaum tsim nrog cov khoom tshwj xeeb.
8. Cov Qauv Zoo:
   • Cov neeg tsim khoom feem ntau muab cov lus qhia tshwj xeeb thiab cov qauv zoo rau HEC cov khoom, ua kom muaj kev sib luag thiab kev ntseeg siab hauv kev ua haujlwm. Cov qauv no yuav suav nrog cov txheej txheem ntsig txog qhov hnyav molecular, purity, thiab lwm yam khoom muaj feem xyuam.

Hydroxyethyl cellulose nrog qhov hnyav molecular ntawm 1000000 yog ntau yam polymer nrog ntau yam kev siv thoob plaws hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv formulations uas siab viscosity thiab dej solubility yog cov yam ntxwv tseem ceeb. Nws yog ib qho tseem ceeb kom ua raws li cov lus pom zoo thiab cov qauv tsim los ntawm cov tuam txhab tsim khoom kom tau txais txiaj ntsig zoo hauv cov ntawv thov tshwj xeeb.
