Nyob rau hauv cov ntaub ntawv gypsum, MHEC, raws li tus neeg saib xyuas dej thiab cov thickener, tuaj yeem txhim kho cov dej tuav ntawm gypsum thiab tiv thaiv nws los ntawm kev tawg vim dej ntau dhau thaum lub sijhawm ziab. Nyob rau tib lub sijhawm, MHEC tseem tuaj yeem txhim kho kev tsim kho ntawm gypsum, ua kom nws smoother, yooj yim rau kev thov thiab sib kis, yog li txhim kho qhov flatness thiab zoo nkauj ntawm cov khoom tiav.
2. Txheej thiab xim kev lag luam
2.1 Latex xim
MHEC tseem ua lub luag haujlwm tseem ceeb hauv cov xim latex, feem ntau yog cov thickener thiab rheology regulator. Nws tuaj yeem txhim kho qhov fluidity thiab kev tsim kho ntawm cov xim, tsis txhob sagging, thiab txhim kho cov txheej txheem ntawm cov xim. Tsis tas li ntawd, MHEC kuj tuaj yeem kho qhov gloss ntawm cov xim zaj duab xis, ua rau cov xim pleev xim zoo nkauj dua thiab zoo nkauj dua. MHEC tseem tuaj yeem txhim kho cov tshuaj txhuam hniav thiab dej tsis kam ntawm cov xim pleev xim, yog li ua kom lub neej ua haujlwm ntawm cov xim.
2.2 Architectural txheej
Hauv architectural coatings, MHEC tuaj yeem txhim kho cov dej tuav ntawm cov xim thiab tiv thaiv cov xim tsis txhob tawg thiab poob vim dej ntau dhau thaum lub sijhawm ziab. Nws tseem tuaj yeem txhim kho qhov adhesion ntawm cov xim, ua rau cov xim muaj zog ntxiv rau ntawm phab ntsa saum npoo, thiab txhim kho huab cua tsis kam thiab tiv thaiv kev laus ntawm cov xim.
3. Tshuaj pleev ib ce thiab tshuaj txhua hnub
Hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej, MHEC yog dav siv los ua cov thickener, emulsion stabilizer thiab moisturizer. Piv txwv li, nyob rau hauv cov khoom xws li tshuaj pleev ib ce, cream, tshuaj zawv plaub hau thiab txias, MHEC tuaj yeem kho cov viscosity ntawm cov khoom, txhim kho nws cov kev ntxhib los mos, thiab ua kom yooj yim rau kev thov thiab nqus. Tsis tas li ntawd, vim nws cov khoom tsis-ionic, MHEC tsis ua rau tawv nqaij thiab plaub hau thiab muaj biocompatibility zoo, yog li nws yog qhov tsim nyog rau ntau yam kev tu tawv nqaij thiab cov khoom tu plaub hau.
4. Kev lag luam kws tshuaj
Hauv kev lag luam kws tshuaj, MHEC feem ntau yog siv rau hauv cov ntsiav tshuaj thiab tshuaj ntsiav ua ib zaj duab xis qub, binder thiab disintegrant. Nws tuaj yeem pab cov tshuaj maj mam tso tawm hauv lub plab zom mov, yog li ua tiav lub hom phiaj ntawm kev siv tshuaj ntev ntev. Tsis tas li ntawd, MHEC kuj tseem siv rau hauv kev npaj xws li qhov muag tee thiab tshuaj pleev ua cov thickener thiab stabilizer los txhim kho cov adhesion thiab persistence ntawm cov tshuaj.
