Hydroxyethyl Methyl Cellulose (MHEC)
Methyl Hydroxyethyl Cellulose (MHEC/HEMC)
CAS:9032-42-2
Hydroxyethyl Methyl Cellulose (HEMC) kuj tseem muaj npe hu uaMethyl Hydroxyethyl Cellulose(MHEC), ib qho cellulose ether uas muaj ntau yam kev ua tau zoo, siv tau ua tus neeg sawv cev khaws dej zoo, stabilizer, nplaum thiab tus neeg sawv cev ua zaj duab xis hauv cov ntaub ntawv tsim kho. MHEC/HEMC siv dav hauv kev siv hauv kev lag luam, xws li kev tsim kho, tshuaj ntxuav tes, xim thiab txheej, peb kuj tuaj yeem muab HEMC raws li cov neeg siv khoom xav tau. Tom qab hloov kho thiab kho qhov chaw, peb tuaj yeem tau txais cov khoom uas tau tawg hauv dej sai sai, ua kom lub sijhawm qhib ntev dua, tiv thaiv kev sagging, thiab lwm yam.

Cov Qauv Tshuaj ntawm MHEC
MHEC yog tsim los ntawmetherifying ntuj cellulosenrogpawg methyl thiab hydroxyethylCov kev hloov kho no txhim kho nws covKev yaj dej, viscosity, thiab kev sib haum xeebnrog cov ntaub ntawv sib txawv.
Cov Khoom Tseem Ceeb ntawm MHEC:
- Kev Yaj Hauv Dej: Yaj hauv dej kub thiab dej txias, tsim cov tshuaj meej.
- Muaj peev xwm ua kom tuab: Muab cov viscosity siab thiab kev tswj hwm rheology zoo heev.
- Kev Khaws Dej: Tiv thaiv kev poob dej hauv cov khoom siv cement thiab gypsum, txhim kho kev kho thiab kev nplaum.
- Xwm Txheej Tsis Yog Ionic: Sib xws nrog ntau yam tshuaj lom neeg, suav nrog cov ntsev thiab surfactants.
- Muaj peev xwm tsim zaj duab xis: Tsim cov zaj duab xis uas yoog tau thiab ruaj khov, muaj txiaj ntsig zoo rau kev siv tshuaj pleev xim thiab kev siv tshuaj.
- Thermal Stability: Tiv taus cua sov, ua rau nws tsim nyog rau cov ntawv thov kub siab.

Cov txiaj ntsig ntawm kev siv MHEC
✔ Kev Khaws Dej Zoo Kawg Nkaus - Tiv thaiv kom qhuav ua ntej lub sijhawm hauv kev tsim kho thiab kev siv tshuaj pleev ib ce.
✔ Kev nplaum zoo dua - Txhim kho lub zog sib txuas hauv cov nplaum pobzeb thiab cov mortars.
✔ Ruaj Khoov Thoob Plaws pH Ntau Yam - Ua haujlwm tau zoo hauv cov chaw acidic, nruab nrab, thiab alkaline.
✔ Kev Sib Tw Tsis-Ionic - Ua haujlwm zoo nrog cov ntsev, surfactants, thiab lwm yam polymers.
✔ Txhim kho Rheology thiab Flow Properties - Tso cai rau kev tswj viscosity, tiv thaiv dripping thiab sagging.
Ntim:
Cov khoom MHEC/HEMC tau ntim rau hauv lub hnab ntawv peb txheej nrog lub hnab polyethylene sab hauv uas muaj zog, qhov hnyav tag nrho yog 25kg ib lub hnab.
Kev Khaws Cia:
Khaws cia rau hauv qhov chaw txias thiab qhuav, deb ntawm cov dej noo, hnub, hluav taws, los nag.
