Cellulose neeg muaj cai (MHEC)

Methyl hydrotyl cellulose(MHEC) yog hom cellulose ether uas tau siv dav hauv ntau yam kev lag luam rau nws cov khoom ntau. Ntawm no yog ib qho kev qhia txog MHEC:

Tus qauv:

MHEC yog hloov kho cellulose ether tau los ntawm cellulose los ntawm cov txheej txheem ntawm cov tshuaj lom neeg. Nws yog tus cwj pwm los ntawm muaj cov pab pawg methyl thiab hydroxyethyl ntawm lub cellulose cellebone.

Khoom:

1. Dej solubility: MHEC yog soluble hauv dej txias, sib sau cov ntsiab lus meej thiab khov kho.
2. Thickening: nws ua rau pom cov khoom siv zoo heev, ua rau nws muaj txiaj ntsig zoo li kev ntseeg rheology hauv ntau yam qauv.
3. Zaj duab xis tsim: MHEC tuaj yeem tsim cov yeeb yaj kiab hloov tau thiab sib xyaw ua ke, ua rau nws siv hauv cov txheej txheem thiab cov nplaum.
4. STABILITY: Nws muab cov ruaj khov rau emulsions thiab ncua, txhim kho lub txee lub neej ntawm cov khoom lag luam.
5. Adhesion: MHEC paub txog nws cov nplaum nplaum, ua rau muaj kev txhim kho adhesion hauv qee cov ntawv thov.

Cov Ntawv Thov:

1. Kev Lag Luam Kev Tsim Kho Kev Tsim Kho:
   • Cov nplaum nplaum: MHEC yog siv rau hauv cov nplais nplaum kom txhim kho kev ua haujlwm, khaws dej, thiab cov tshuaj nplaum.
   • Mortars thiab cov neeg ua haujlwm: nws tau ua haujlwm hauv Mement-raws li Caent-raws li cov neeg Mortars thiab cov khoom siv ua kom nce cov dej tuav thiab ua haujlwm.
   • Kev Ntsuas Tus Kheej Kev Ua Si: MHEC yog siv rau hauv tus kheej-qib sib txuas rau nws cov pa thickening thiab ruaj khov.
2. Cov xim pleev xim thiab pleev xim:
   • MHEC tau siv hauv cov xim pleev xim rau cov dej thiab txheej txheej ua ib qho tuab thiab stabilizer. Nws pab txhawb kom zoo dua cov teeb meem thiab qhov ua tau zoo tag nrho ntawm cov txheej.
3. Cov nplaum:
   • MHEC tau siv nyob rau hauv ntau cov nplaum nplaum kom txhim kho adhesion thiab txhim kho cov khoom zoo nkauj ntawm cov nplaum ntawm cov nplaum nplaum.
4. Kws Tshuaj:
   • Hauv cov chaw kuaj tshuaj, MHEC tau siv los ua cov phau ntawv, ua txhaum cai, thiab zaj duab xis-ua tus neeg sawv cev hauv cov ntsiav tshuaj ua qauv.

Txheej txheem tsim khoom:

Kev tsim cov MHEC yuav cuam tshuam nrog lub etherification ntawm cellulose nrog kev sib xyaw methyl chloride thiab ethylene oxide. Cov xwm txheej tshwj xeeb thiab reagent sib piv yog tswj kom ua tiav cov qib siab ntawm kev hloov pauv (DS) thiab txhawm rau ua cov khoom kawg ntawm cov khoom kawg.

Tswjhwm Zoo:

Kev ntsuas kev tswj hwm zoo, suav nrog kev ntsuas kev ntsuas piv txwv xws li cov qauv sib nqus Nuclear, tau ua haujlwm kom ntseeg tau tias muaj cov qauv ntawm cov qauv yuav tsum tau ua.

MHEC cov versatility ua rau nws muaj txiaj ntsig zoo hauv ntau hom kev tsim qauv, ua rau txhim kho kev ua tau zoo hauv cov ntaub ntawv tsim kho, cov nplaum, thiab kws tshuaj. Cov tuam txhab tsim yuav muaj cov qib sib txawv ntawm MHEC kom tau raws li cov kev xav tau sib txawv ntawm ntau yam kev lag luam.
