Kev txiav txim siab qhov "zoo tshaj" cellulose ether nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov npaj. Cov cellulose ethers sib txawv muaj cov khoom sib txawv, xws li viscosity, solubility, thiab film-forming peev xwm, ua rau lawv haum rau cov hom phiaj sib txawv. Nov yog qee qhov kev siv ntau thiab suav nrog cellulose ethers:

1. Methyl Cellulose (MC):
   • Cov Khoom Siv: MC paub txog nws qhov muaj peev xwm tuav tau dej siab, ua rau nws tsim nyog siv rau hauv daim ntawv thov thickening, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho kev lag luam. Nws kuj yog siv rau hauv cov tshuaj thiab khoom noj khoom haus.
   • Daim ntaub ntawv: Mortar thiab cement formulations, tshuaj ntsiav tshuaj, thiab raws li ib tug thickening neeg sawv cev nyob rau hauv cov khoom noj.
2. Hydroxyethyl Cellulose (HEC):
   • Khoom: HEC muaj dej solubility zoo thiab muaj ntau yam nyob rau hauv cov nqe lus ntawm viscosity tswj. Nws yog feem ntau siv nyob rau hauv ob qho tib si kev lag luam thiab cov khoom siv.
   • Daim ntaub ntawv: Cov xim thiab txheej, cov khoom siv tu tus kheej (shampoos, lotions), adhesives, thiab tshuaj formulations.
3. Carboxymethyl Cellulose (CMC):
   • Cov Khoom Siv: CMC yog dej-soluble thiab muaj cov khoom tuab zoo thiab ruaj khov. Nws yog dav siv nyob rau hauv cov khoom noj thiab tshuaj industries.
   • Daim ntaub ntawv: khoom noj khoom haus (raws li cov thickener thiab stabilizer), tshuaj, tshuaj pleev ib ce, textiles, thiab drilling kua nyob rau hauv cov roj thiab roj kev lag luam.
4. Hydroxypropyl Methyl Cellulose (HPMC):
   • Cov Khoom: HPMC muaj qhov sib npaug zoo ntawm cov dej solubility, thermal gelation, thiab cov khoom ua yeeb yaj kiab. Nws yog dav siv hauv kev tsim kho thiab kev siv tshuaj.
   • Daim ntaub ntawv: Pobzeb nplaum, cement-raws li renders, qhov ncauj tshuaj formulations, thiab tswj-tso tshuaj xa cov tshuab.
5. Ethyl Hydroxyethyl Cellulose (EHEC):
   • Cov Khoom Siv: EHEC paub txog nws cov viscosity siab thiab dej tuav, ua rau nws tsim nyog rau kev thov hauv kev tsim kho thiab tshuaj.
   • Daim ntaub ntawv: Mortar additives, thickening agents nyob rau hauv pharmaceuticals, thiab tshuaj pleev ib ce.
6. Sodium Carboxymethyl Cellulose (Na-CMC):
   • Khoom: Na-CMC yog cov dej-soluble cellulose ether nrog cov thickening zoo heev thiab stabilizing zog. Nws feem ntau yog siv rau hauv cov khoom noj thiab ntau yam kev lag luam.
   • Daim ntaub ntawv: khoom noj khoom haus (raws li cov thickener thiab stabilizer), tshuaj, textiles, thiab drilling kua.
7. Microcrystalline Cellulose (MCC):
   • Cov Khoom: MCC muaj cov khoom me me, crystalline thiab feem ntau yog siv los ua cov ntawv khi thiab muab tso rau hauv cov tshuaj ntsiav tshuaj.
   • Daim ntawv thov: Cov tshuaj ntsiav tshuaj thiab tshuaj ntsiav.
8. Sodium Carboxymethyl Starch (CMS):
   • Cov Khoom: CMS yog cov hmoov txhuv nplej siab nrog cov khoom zoo ib yam li Na-CMC. Nws yog feem ntau siv hauv kev lag luam zaub mov.
   • Daim ntaub ntawv: Khoom noj khoom haus (raws li cov thickener thiab stabilizer), textiles, thiab kws tshuaj.

Thaum xaiv cov cellulose ether rau ib daim ntawv thov tshwj xeeb, nws yog ib qho tseem ceeb uas yuav tau xav txog yam xws li qhov xav tau viscosity, solubility, stability, thiab lwm yam kev ua tau zoo. Tsis tas li ntawd, kev ua raws li cov qauv kev tswj hwm thiab kev txiav txim siab ib puag ncig yuav tsum raug coj mus rau hauv tus account. Cov neeg tsim khoom feem ntau muab cov ntaub ntawv qhia txog cov ncauj lus kom ntxaws txog cov khoom thiab pom zoo siv cov cellulose ethers tshwj xeeb.
