Lub npe tshuaj lom neeg,Hydroxypropyl Methyl Cellulose (HPMC), Hydroxyethyl Methyl Cellulose (HEMC),Sodium Carboxymethyl Cellulose (CMC), Hydroxyethyl cellulose (HEC), Hydrophobically hloov kho HEC (HMHEC),Methyl cellulose (MC), Methyl hydroxyethyl cellulose (MHEC), Ethyl hydroxyethyl cellulose (EHEC), Hydrophobically hloov kho cellulose ethers (EHEC, HM-EHEC).
Cellulose ethers yog tsim los ntawm kev hloov pauv tshuaj ntawm cellulose nrog qee yam tshuaj lom neeg. Cellulose ethers yog cov polymers uas tsis yog ionic uas yaj tau hauv dej raws li ntau tshaj plaws ntawm cov polymer cellulose ntuj. Ntau tshaj 70 xyoo, cov khoom no tau ua lub luag haujlwm tseem ceeb hauv cov ntawv thov no, los ntawm cov khoom tsim qauv, cov khoom siv av nplaum thiab cov xim rau cov khoom noj, cov tshuaj pleev ib ce thiab cov tshuaj. Cellulose ethers yog siv ua cov tshuaj ua haujlwm thiab rheological thiab kev ua haujlwm ua cov tshuaj thickening, emulsifiers, cov tshuaj tiv thaiv colloids, cov stabilisers thiab rau kev khaws cia dej.
Hauv kev tsim kho, cellulose ethers ua haujlwm ua cov thickeners, binders, movie formers thiab cov dej-undefined txij nkawm cov neeg sawv cev, suspensions assists, surfactants, lubricants, tiv thaiv colloids thiab emulsifiers. Ntxiv mus, cov dej tshuaj ntawm cov cellulose ethers tshwj xeeb thermally gel, ib lub tsev tshwj xeeb uas siv lub luag haujlwm tseem ceeb hauv ntau yam kev siv. Qhov kev sib xyaw ua ke ntawm cov yam ntxwv no tsis muaj nyob hauv txhua lwm yam dej-soluble polymer.
Qhov tseeb tias ntau yam khoom muaj txiaj ntsig zoo tib lub sijhawm thiab feem ntau teb rau hauv kev sib xyaw ua ke tuaj yeem yog qhov txiaj ntsig nyiaj txiag tseem ceeb. Hauv ntau daim ntawv thov, ntau cov khoom xyaw yuav tsum tau ua kom ua tiav tib txoj haujlwm ua los ntawm ib qho khoom cellulose ether. Ntxiv mus, cellulose ethers muaj txiaj ntsig zoo, feem ntau muab cov txiaj ntsig zoo tshaj plaws ntawm qhov txo qis dua li lwm cov polymers uas yaj hauv dej.

Anxin Cellulosehais kom ua raws li txoj kev xav ntawm 'Zoo heev, Kev ua tau zoo, Kev ua siab dawb siab zoo thiab txoj hauv kev ua haujlwm hauv ntiaj teb' kom xa koj nrog cov neeg muab kev pabcuam zoo rau Kev Muag Khoom Kub rau Tuam Tshoj Cellulose Ether nrog Kev Txhim Kho Sag-Resistance, Zoo heev, tus nqi sib tw, kev xa khoom sai thiab kev pabcuam txhim khu kev qha tau lees paub Zoo siab tso cai rau peb paub koj qhov xav tau ntau npaum li cas hauv txhua pawg loj kom peb tuaj yeem qhia koj yooj yim.
Kub Muag rau Tuam Tshoj cellulose ethers, Txhawm rau kom ua tus thawj coj hauv peb txoj kev lag luam, peb yeej tsis tso tseg kev sib tw qhov kev txwv hauv txhua yam los tsim cov kev daws teeb meem zoo tagnrho. Hauv nws txoj kev, Peb tuaj yeem nplua nuj peb txoj kev ua neej thiab txhawb nqa ib puag ncig zoo dua rau lub zej zog thoob ntiaj teb.
