Methylhydroxyethylcellulose (MHEC) yog ib qho khoom siv feem ntau siv hauv cov khoom siv cement xws li mortar thiab pob zeb.Nws belongs rau tsev neeg ntawm cellulose ethers thiab yog muab rho tawm los ntawm tej yam ntuj tso cellulose los ntawm ib tug tshuaj hloov txheej txheem.
MHEC feem ntau yog siv los ua cov thickener, dej tuav tus neeg saib xyuas thiab rheology hloov kho hauv cov khoom siv cement.Nws pab txhim kho kev ua haujlwm thiab sib xws ntawm cov cement sib tov, ua rau lawv yooj yim dua thaum siv.MHEC tseem muaj ntau yam txiaj ntsig, suav nrog:
Kev tuav dej: MHEC muaj peev xwm khaws cov dej, uas tiv thaiv kom qhuav ntxov ntxov ntawm cov khoom siv cement.Qhov no yog tshwj xeeb tshaj yog pab tau nyob rau hauv kub, qhuav huab cua los yog ncua sij hawm ua hauj lwm yuav tsum tau.
Txhim kho Adhesion: MHEC txhim kho qhov adhesion ntawm cov ntaub ntawv cementitious thiab lwm yam substrates xws li cib, pob zeb lossis pobzeb.Nws pab txhim kho daim ntawv cog lus muaj zog thiab txo qhov kev pheej hmoo ntawm delamination lossis sib cais.
Lub Sijhawm Qhib Ntxiv: Lub sijhawm qhib yog lub sijhawm uas cov tshuaj khib lossis cov nplaum tseem siv tau tom qab kev tsim kho.MHEC tso cai rau lub sijhawm qhib ntev dua, tso cai rau lub sijhawm ua haujlwm ntev dua thiab ua kom zoo dua ntawm cov khoom ua ntej nws solidifies.
Enhanced Sag Resistance: Sag resistance yog hais txog lub peev xwm ntawm cov khoom siv los tiv thaiv ntsug slumping lossis sagging thaum siv rau ntawm qhov chaw ntsug.MHEC tuaj yeem txhim kho cov sag tsis kam ntawm cov khoom siv cement, ua kom zoo dua adhesion thiab txo deformation.
Txhim kho kev ua haujlwm: MHEC hloov kho cov rheology ntawm cov khoom siv cement, txhim kho lawv cov dej ntws thiab kev sib kis.Nws pab ua kom muaj kev sib luag zoo dua thiab zoo sib xws, ua kom yooj yim rau kev tuav thiab siv.
Lub Sijhawm Tswjhwm: MHEC tuaj yeem cuam tshuam lub sijhawm teem sijhawm ntawm cov khoom siv cement, uas tso cai rau kev tswj xyuas ntau dua ntawm cov txheej txheem kho.Qhov no yog tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv cov xwm txheej uas yuav tsum tau teem sij hawm ntev los yog luv dua.
Nws yuav tsum raug sau tseg tias cov khoom tshwj xeeb thiab kev ua haujlwm ntawm MHEC tuaj yeem sib txawv nyob ntawm nws qhov hnyav molecular, qib kev hloov pauv, thiab lwm yam.Cov tuam txhab sib txawv tuaj yeem muab cov khoom lag luam MHEC nrog cov yam ntxwv sib txawv kom haum rau cov ntawv thov tshwj xeeb.
Zuag qhia tag nrho, MHEC yog cov khoom siv ntau yam ntxiv uas tuaj yeem txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv cement, muab cov txiaj ntsig xws li txhim kho adhesion, dej tuav, sag resistance thiab tswj lub sijhawm.
