Gypsum Khoom: Hauv gypsum-raws li cov ntaub ntawv xws li kev sib koom ua ke thiab plasters, MHEC ua haujlwm ua tus neeg ua kom tuab, txhim kho lawv qhov sib xws thiab sag tsis kam.
2. Pharmaceuticals:
Cov Khoom Siv Hauv Qhov Ncauj: MHEC yog siv rau hauv cov tshuaj txhuam hniav formulations ua cov thickener thiab binder. Nws pab tswj qhov xav tau sib xws ntawm cov tshuaj txhuam hniav thaum tseem ua rau nws cov khoom nplaum.
Ophthalmic Solutions: Nyob rau hauv qhov muag tee thiab tshuaj pleev, MHEC ua raws li lub viscosity modifier, muab cov thickness tsim nyog rau kev yooj yim ntawm daim ntawv thov thiab ntev kev sib cuag nrog lub qhov muag nto.
Tshuaj pleev ib ce: MHEC yog muab tso rau hauv ntau yam cream, tshuaj pleev ib ce, thiab gels raws li ib tug thickening neeg sawv cev thiab stabilizer, txhim kho cov kev ntxhib los mos thiab kis tau tus mob ntawm cov khoom.
3. Cov Khoom Siv Kho Tus Kheej:
Shampoos thiab Conditioners: MHEC txhim khu cov viscosity ntawm cov khoom tu plaub hau, muab ib tug du thiab creamy sib xws uas txhim kho kev sib kis thiab xyuas kom meej txawm faib cov khoom xyaw.
Daim tawv nqaij Cleansers: Nyob rau hauv lub ntsej muag ntxuav thiab ntxuav lub cev, MHEC ua raws li ib tug me ntsis thickener thiab stabilizer, pab txhawb rau cov khoom zoo nkauj thiab foaming zog.
Tshuaj pleev ib ce: MHEC yog siv rau hauv cov tshuaj pleev ib ce xws li cream, tshuaj pleev ib ce, thiab pleev cov khoom los kho viscosity, txhim kho kev ntxhib los mos, thiab stabilize emulsions.
4. Kev lag luam zaub mov:
Khoom noj khoom haus additives: MHEC yog ua hauj lwm raws li ib tug thickener, stabilizer, thiab emulsifier nyob rau hauv ntau yam khoom noj, nrog rau cov kua ntses, hnav khaub ncaws, khoom noj siv mis, thiab khoom qab zib. Nws pab tswj kev xav tau kev ntxhib los mos, tiv thaiv syneresis, thiab txhim khu lub qhov ncauj.
Gluten-Dawb Baking: Hauv gluten-dawb ci, MHEC tuaj yeem siv los ua cov khoom viscoelastic ntawm gluten, txhim kho cov khob noom cookie zoo sib xws thiab kev ntxhib los mos hauv cov khoom xws li qhob cij, ncuav, thiab pastries.
5. Xim thiab Txheej:
Latex Paints: MHEC yog ntxiv rau cov xim latex thiab coatings ua cov thickener thiab rheology modifier. Nws txhim kho kev txhuam, daim ntawv thov rau cov menyuam, thiab kev ua haujlwm tag nrho ntawm cov xim zaj duab xis los ntawm kev tiv thaiv sagging thiab drips.
Kev Siv Cov Txheej Txheem: Hauv cov txheej txheem rau phab ntsa, qab nthab, thiab facades, MHEC txhim kho cov viscosity thiab kev ua haujlwm ntawm cov qauv tsim, kom ntseeg tau tias muaj kev tiv thaiv zoo thiab adhesion.
6. Adhesives thiab Sealants:
Water-Based Adhesives: MHEC ua hauj lwm raws li ib tug thickening neeg sawv cev nyob rau hauv dej-raws li adhesives thiab sealants, txhim kho tackiness, daim ntawv cog lus zog, thiab daim ntawv thov zog.
Pobzeb Grouts: Nyob rau hauv cov pobzeb grout formulations, MHEC ua raws li ib tug rheology modifier, txhim khu kev khiav hauj lwm thiab tiv thaiv shrinkage thiab tawg thaum kho.
7. Lwm yam kev siv:
Roj Drilling Fluids: MHEC yog siv nyob rau hauv cov roj zoo drilling kua ua ib tug viscosifier thiab kua-tso tswj tus neeg saib xyuas, pab tswj lub qhov stability thiab tiv thaiv kom txhob muaj dej tsiv teb tsaws.
Textile Printing: Hauv textile luam ntawv pastes, MHEC yog ua hauj lwm raws li ib tug thickener thiab binder, yooj yim rau daim ntawv thov ntawm dyes thiab pigments rau ntawm daim ntaub.
Methylhydroxyethylcellulose (MHEC) yog ntau yam cellulose ether nrog ntau yam kev siv thoob plaws ntau yam kev lag luam. Nws muaj peev xwm ua kom tuab, ruaj khov, thiab hloov kho rheological zog ntawm formulations ua rau nws indispensable nyob rau hauv kev tsim kho, tshuaj, khoom noj khoom haus, tshuaj pleev ib ce, adhesives, thiab lwm yam. Raws li kev lag luam txuas ntxiv tsim kho tshiab thiab tsim cov khoom tshiab, MHEC zoo li yuav tseem yog cov khoom tseem ceeb hauv suav tsis txheeb, pab txhawb rau lawv cov kev ua tau zoo, kev ua haujlwm, thiab cov neeg siv khoom txaus siab.
