MHEC, los yog Methyl Hydroxyethyl Cellulose, yog ib qho kev sib xyaw ua ke uas tau siv ntau yam kev lag luam, tab sis nws feem ntau yog siv hauv kev lag luam qhuav-sib xyaw mortar.Qhuav-sib tov mortars yog hmoov sib tov ntawm cov ntxhia aggregates thiab cov ntaub ntawv khi uas tuaj yeem sib xyaw nrog dej los ua cov tshuaj txhuam rau ntau yam kev siv xws li plastering, plastering thiab tiling.
MHEC yog cov khoom siv ntxiv uas txhim kho kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom siv khib nyiab qhuav los ntawm kev txhim kho lawv daim ntawv cog lus lub zog, tuav dej thiab rheological zog.Nws ua tiav cov txiaj ntsig no los ntawm kev ua cov thickener, rheology modifier thiab dej tuav tus neeg sawv cev.Los ntawm kev tswj cov rheological zog ntawm qhov sib tov, MHEC tuaj yeem siv los ua kom tiav qhov xav tau sib xws, ntws thiab teeb tsa cov khoom sib xyaw.
Ib qho tseem ceeb tshaj plaws ntawm kev siv MHEC hauv cov tshuaj khib nyiab qhuav yog qhov zoo sib xws ntawm cov khoom sib xyaw uas tuaj yeem ua tiav.Nrog kev pab los ntawm MHEC, cov tshuab ziab khaub ncaws qhuav tuaj yeem tswj tau zoo dua qhov viscosity, ntws thiab teeb tsa cov yam ntxwv ntawm cov khoom sib xyaw, yog li ua kom cov khoom zoo sib xws thiab kev ua haujlwm zoo.Tsis tsuas yog qhov no ua rau kom tag nrho cov kav ntev thiab lub neej ntev ntawm lub tsev, nws tseem txuag cov nqi los ntawm kev txo cov khoom pov tseg thiab rov ua haujlwm dua.
Tsis tas li ntawd, MHEC pab txhim kho kev ua haujlwm ntawm cov khoom siv tshuaj khib nyiab qhuav.Los ntawm kev nce lub sijhawm ua haujlwm ntawm kev sib tov, MHEC ua kom yooj yim rau kev lis, kis thiab ua tiav cov tshuaj khib nyiab.Qhov kom zoo dua no tshwj xeeb tshaj yog nyob rau hauv kev tsim kho loj loj uas cov khoom sib tov qhuav yog thauj mus ntev thiab kev ua tau zoo yog qhov tseem ceeb rau kev ua haujlwm zoo ib yam.
MHEC tseem ua lub luag haujlwm tseem ceeb hauv kev ua kom lub zog thiab ua haujlwm ntev ntawm cov khoom tiav.Los ntawm kev ntxiv MHEC rau qhov sib tov, cov tuam txhab tsim khoom tuaj yeem txhim kho qhov adhesion thiab cohesion ntawm qhuav-mix mortars, uas ua rau muaj kev sib raug zoo rau lub substrate nto.Qhov no tsis tsuas yog txhim kho lub neej ntawm mortar, tab sis kuj txhim kho tag nrho cov qauv kev ncaj ncees ntawm lub tsev.
Lwm qhov zoo dua ntawm kev siv MHEC hauv cov tshuaj khib nyiab qhuav yog nws muaj peev xwm ua kom cov dej tuav tau.Nyob rau hauv ib puag ncig kev tsim kho, kev tuav dej yog qhov tseem ceeb los xyuas kom meej tias mortar khaws nws lub zog thiab tuab txawm tias nyob rau hauv cov xwm txheej tsis zoo xws li cov av noo siab lossis huab cua kub.MHEC pab khaws cov dej noo hauv qhov sib tov, txo qis shrinkage, tawg thiab pin blistering.Qhov no ua rau cov khoom kawg muaj zog dua thiab muaj zog, tuaj yeem tiv taus qhov kev sim ntawm lub sijhawm thiab huab cua.
Ntxiv nrog rau cov txiaj ntsig no, MHEC muaj ntau yam thiab tuaj yeem hloov kho kom tau raws li cov kev xav tau tshwj xeeb.Piv txwv li, los ntawm qhov sib txawv ntawm kev hloov pauv thiab qhov hnyav molecular, cov khoom ntawm MHECs tuaj yeem hloov kho rau cov ntawv thov tshwj xeeb.Yog li ntawd, MHEC tuaj yeem siv dav hauv ntau qhov kev tsim kho nrog cov kev xav tau sib txawv, xws li cov pob zeb muaj zog, cov dej tsis muaj dej, cov nplais nplaum, thiab lwm yam.
Raws li cov ntsiab lus, MHEC yog undoubtedly ib tug high-kev ua tau zoo additive uas tau revolutionized lub qhuav-mix mortar kev lag luam.Nws txhim kho qhov sib xws, lub zog thiab dej khaws cia ntawm cov khoom siv khib nyiab qhuav, ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv niaj hnub no.Los ntawm kev ua kom cov tuam txhab tsim cov khoom sib xyaw ua ke zoo sib xws, MHEC ua rau muaj txiaj ntsig zoo thiab muaj txiaj ntsig ntawm kev tsim kho kev lag luam.Tsis muaj qhov xav tsis thoob, yog li ntawd, ntau tus hauv kev lag luam xav txog MHEC los ua kev hloov pauv kev ua si rau kev lag luam qhuav-sib xyaw.
