MHEC (methyl hydrotyl cellulose) yog lwm cov cellulose-raws polymer uas feem ntau siv los ua cov ntawv sau ntxiv hauv cov ntawv thov. Nws muaj cov txiaj ntsig zoo sib xws rau HPMC, tab sis muaj qee qhov sib txawv hauv cov khoom. Cov hauv qab no yog cov ntawv thov ntawm MHEC hauv Txawb Plas cov Plasters:
Dej khaws cia: MHEC nce cov dej khaws cia hauv cov plastering sib xyaw, yog li ua kom muaj zog ua haujlwm. Nws pab tiv thaiv qhov sib tov ntawm ziab ua ntej ntxov, tso cai rau lub sijhawm txaus rau kev thov thiab xov.
Kev ua haujlwm: MHEC txhim kho lub zog ua haujlwm thiab kev ua tau ntawm cov khoom siv plastering. Nws txhim kho cohesion thiab txaus rau cov khoom, ua kom yooj yim rau kev thov thiab ua tiav qhov ua tiav ntawm cov chaw.
Adhesion: mHEC txhawb nqa zoo dua adhesion ntawm cov plaster rau substrate. Nws pab kom muaj kev sib raug zoo ntawm cov plaster thiab pib ua rau sab nraud, txo qhov kev pheej hmoo ntawm kev cuam tshuam lossis sib cais.
Sag tiv thaiv: MHEC coj mus rau cov plaster kom sib xyaw, txhim kho nws txoj kev tiv taus sag lossis swb thaum thov lossis ua haujlwm. Nws pab kom tswj cov kev xav tau tuab thiab cov duab ntawm cov plaster thaum ntawv thov.
Nthuav tawm: los ntawm kev ntxiv MHEC, cov khoom siv plastering kis tau zoo dua thiab yog li ua kom nruj tawg. Nws pab txo qis qhov tshwm sim ntawm cov kab nrib pleb tshwm sim los ntawm kev ziab shrinkage lossis thermal expansion / Confaction.
Durability: MHEC muaj txiaj ntsig rau lub durability ntawm lub plastering system. Nws tsim zaj yeeb yaj kiab tiv thaiv thaum qhuav, nce tsis kam mus rau cov dej nkag, huab cua thiab lwm cov neeg ib puag ncig.
Rheology tswj: MHEC Cov kev ua raws li kev hloov kho rheology, cuam tshuam rau kev ntws thiab ua haujlwm ntawm kev sib xyaw sib xyaw. Nws pab kom tswj viscosity, txhim kho kev nqus tawm lossis txau cov yam ntxwv, thiab tiv thaiv kev sib cais lossis sib cais ntawm cov khoom siv.
Nws yuav tsum raug sau tseg tias MHEC tshwj xeeb yuav sib txawv raws li qhov xav tau ntawm lub plastering system, xws li yuav tsum thickness, kev kho mob thiab lwm yam. Cov ntaub ntawv tsim khoom thiab cov ntawv qhia cov ntaub ntawv thiab cov lus qhia txog kev siv thiab cov lus qhia rau kev sib xyaw ua ke Gyasitious formulations.
