Methyl hydroxyethyl cellulose (MHEC) yog ib qho tseem ceeb ntawm cov cellulose ether derivative, dav siv hauv cov khoom siv hauv tsev, txheej, ceramics, tshuaj pleev ib ce thiab lwm yam lag luam. Raws li cov khoom siv ntxiv, MHEC plays lub luag haujlwm tseem ceeb hauv ntau yam kev siv vim nws cov thickening zoo heev, dej tuav, adhesion thiab zaj duab xis tsim cov khoom.
1. Kev siv hauv cov khoom siv hauv tsev
Hauv cov khoom siv hauv tsev, MHEC tau siv dav hauv cov cement-raws li thiab gypsum-raws li mortar qhuav, feem ntau yog cov thickener, dej-retaining agent thiab binder. MHEC tuaj yeem txhim kho kev tsim kho kev ua haujlwm ntawm mortar, txhim kho nws cov dej tuav, thiab tiv thaiv mortar tawg los ntawm kev poob dej sai. Tsis tas li ntawd, MHEC tuaj yeem txhim kho qhov adhesion thiab lubrication ntawm mortar, ua kev tsim kho kom zoo dua.
Hauv cov pobzeb nplaum thiab grouts, qhov sib ntxiv ntawm MHEC tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv thiab txuas ntxiv lub sijhawm qhib, muab cov neeg ua haujlwm tsim kho ntau lub sijhawm los kho. Nyob rau tib lub sijhawm, MHEC kuj tuaj yeem txhim kho qhov tawg tsis kam thiab shrinkage tsis kam ntawm tus neeg sawv cev caulking kom ntseeg tau tias nws ua haujlwm ruaj khov mus ntev.
2. Daim ntawv thov hauv kev lag luam txheej
Hauv kev lag luam coatings, MHEC feem ntau yog siv los ua cov thickener, stabilizer thiab emulsifier. Vim tias MHEC muaj cov nyhuv thickening zoo heev, nws tuaj yeem tswj tau qhov rheology ntawm txheej txheej, yog li txhim kho kev ua haujlwm thiab qib ntawm txheej txheej. Tsis tas li ntawd, MHEC tseem tuaj yeem txhim kho qhov kev ua haujlwm ntawm cov txheej txheem los tiv thaiv cov txheej txheem thiab xyuas kom muaj kev sib haum xeeb thiab zoo nkauj ntawm txheej.
Nyob rau hauv cov xim latex, cov dej tuav cov khoom ntawm MHEC pab tiv thaiv kom tsis txhob muaj dej nrawm nrawm thaum txheej txheej ziab, yog li zam qhov tshwm sim ntawm qhov tsis xws luag xws li tawg los yog qhov chaw qhuav. Nyob rau tib lub sijhawm, cov yeeb yaj kiab zoo ntawm MHEC tuaj yeem txhim kho cov huab cua tsis kam thiab txhuam tsis kam ntawm cov txheej, ua rau cov txheej txheem ntau dua.
3. Daim ntawv thov hauv kev lag luam ceramic
Hauv kev lag luam ceramic, MHEC yog dav siv los ua kev pab molding thiab binder. Vim nws cov dej tuav tau zoo thiab cov khoom thickening, MHEC tuaj yeem txhim kho cov yas thiab formability ntawm lub cev ceramic, ua rau cov khoom sib txawv thiab ntom. Tsis tas li ntawd, cov khoom sib txuas ntawm MHEC pab txhim kho lub zog ntawm lub cev ntsuab thiab txo qhov kev pheej hmoo ntawm cov kab nrib pleb thaum lub sij hawm sintering.
MHEC tseem ua lub luag haujlwm tseem ceeb hauv ceramic glazes. Nws tuaj yeem tsis tsuas yog txhim kho qhov kev ncua thiab kev ruaj ntseg ntawm glaze, tab sis kuj txhim kho qhov smoothness thiab uniformity ntawm glaze kom paub meej qhov zoo ntawm cov khoom siv ceramic.
4. Cov ntawv thov hauv cov tshuaj pleev ib ce thiab cov khoom siv tu tus kheej
MHEC kuj tau siv dav hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej, feem ntau yog cov thickeners, emulsifiers, stabilizers thiab film-forming agents. Vim nws qhov me me thiab tsis ua rau khaus, MHEC yog qhov tshwj xeeb tshaj yog siv rau hauv cov khoom tu tawv nqaij xws li cream, lotions thiab tshuaj ntxuav lub ntsej muag. Nws tuaj yeem txhim kho qhov sib xws ntawm cov khoom thiab txhim kho nws cov kev ntxhib los mos, ua rau cov khoom smoother thiab yooj yim rau kev thov.
Hauv cov khoom siv tu plaub hau, cov khoom ua yeeb yaj kiab ntawm MHEC pab tsim cov yeeb yaj kiab tiv thaiv ntawm cov plaub hau, txo cov plaub hau puas thaum muab cov plaub hau du thiab muag muag. Tsis tas li ntawd, cov khoom moisturizing ntawm MHEC tseem tuaj yeem ua lub luag haujlwm hauv kev kaw dej thiab moisturizing hauv cov khoom tu tawv nqaij, txuas ntxiv cov nyhuv moisturizing.
5. Daim ntawv thov hauv lwm qhov kev lag luam
Ntxiv nrog rau cov ntawv thov tseem ceeb uas tau hais los saum no, MHEC tseem ua lub luag haujlwm tseem ceeb hauv ntau lwm yam lag luam. Piv txwv li, nyob rau hauv cov roj drilling kev lag luam, MHEC yog siv nyob rau hauv drilling kua raws li ib tug thickener thiab stabilizer los txhim kho lub rheology ntawm lub drilling kua thiab nws muaj peev xwm nqa cuttings. Hauv kev lag luam textile, MHEC yog siv los ua cov thickener rau luam ntawv paste, uas tuaj yeem txhim kho qhov pom tseeb thiab xim ci ci ntawm cov qauv luam tawm.
MHEC kuj tseem siv nyob rau hauv kev lag luam kws tshuaj los ua tus neeg sawv cev thiab cov yeeb yaj kiab tsim rau cov ntsiav tshuaj, uas tuaj yeem txhim kho lub zog thiab zoo ntawm cov ntsiav tshuaj. Tsis tas li ntawd, hauv kev lag luam khoom noj khoom haus, MHEC kuj tseem siv los ua cov thickener thiab emulsifier hauv kev tsim cov seasonings, dej haus thiab khoom noj siv mis los txhim kho saj thiab ruaj khov ntawm cov khoom.
Methylhydroxyethylcellulose (MHEC) tau siv dav hauv cov khoom siv hauv tsev, coatings, ceramics, tshuaj pleev ib ce thiab lwm yam lag luam vim nws cov thickening zoo heev, dej tuav, nplaum thiab zaj duab xis-tsim cov khoom. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev sib txawv ntawm cov kev xav tau ntawm kev ua lag luam, daim ntawv thov kev lag luam ntawm MHEC tseem nthuav dav, thiab nws qhov tseem ceeb hauv ntau qhov kev lag luam yuav dhau los ua qhov tseem ceeb.
