     • Cov Khoom Siv Siv: Hauv mortar, plaster, thiab pobzeb nplaum los txhim kho cov dej tuav thiab ua haujlwm.
     • Coatings thiab Films: Nyob rau hauv zus tau tej cov coatings thiab films rau nws cov zaj duab xis-forming zog.
     • Cov Khoom Siv Kho Tus Kheej: Hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej kom nws cov thickening thiab stabilizing zog.
6. Rheological Control:
   • Qhov sib ntxiv ntawm cellulose hydroxyethyl ether tuaj yeem muab kev tswj hwm ntawm cov khoom rheological ntawm cov kev daws teeb meem, ua rau nws muaj txiaj ntsig zoo hauv cov txheej txheem uas tswj cov viscosity yog qhov tseem ceeb.
7. Biodegradability:
   • Cellulose ethers, suav nrog hydroxyethyl ether derivatives, feem ntau biodegradable, pab txhawb rau lawv cov phooj ywg ib puag ncig.
8. Synthesis:
   • Lub synthesis muaj cov tshuaj tiv thaiv ntawm cellulose nrog ethylene oxide nyob rau hauv lub xub ntiag ntawm alkali. Lub degree ntawm kev hloov pauv thiab qhov hnyav molecular tuaj yeem tswj tau thaum lub sijhawm txheej txheem synthesis.
9. Kev Tshawb Fawb thiab Kev Txhim Kho:
   • Cov kws tshawb fawb thiab cov kws tsim qauv tuaj yeem xaiv cov cellulose hydroxyethyl ethers tshwj xeeb raws li qhov hnyav molecular thiab qib ntawm kev hloov pauv kom ua tiav cov khoom xav tau hauv ntau daim ntawv thov.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom thiab kev siv ntawm cellulose hydroxyethyl ether tuaj yeem sib txawv raws li nws cov yam ntxwv tshwj xeeb, thiab cov ntaub ntawv hais txog muab cov ntsiab lus dav dav. Cov ntaub ntawv ntxaws ntxaws muab los ntawm cov tuam txhab lossis cov neeg muag khoom yog qhov tseem ceeb rau kev nkag siab txog cov khoom tshwj xeeb cellulose hydroxyethyl ether hauv nqe lus nug.
