HIGH VISCOSITY
Hydroxypropyl Methyl Cellulose (HPMC) feem ntau yog siv los ua cov thickener hauv kev siv hauv tsev vim nws tiv thaiv kev sib cais thiab txhim kho kev sib koom ua ke ntawm cov khoom tsim.Nyob rau hauv qhuav mix mortar, lub thickening zog yog txuam nrog lawv cov kua viscosity.HPMC muab cov nplaum nplaum zoo rau cov khib nyiab ntub dej.Qhov ntawd tuaj yeem ua rau kom muaj qhov adhesion ntawm cov khib nyiab ntub dej rau hauv lub hauv paus txheej thiab txhim kho lub sag tsis kam ntawm mortar.
LUB SIJ HAWM QHOV TSEEB
Hydroxypropyl Methyl Cellulose (HPMC) tuaj yeem tiv thaiv tau sai heev thiab tsis tshua muaj dej nkag mus rau hauv lub hauv paus nto hauv cov khoom siv cement, tso cai rau cov dej ntau nyob hauv mortar thiab koom nrog cov cement hydration cov tshuaj tiv thaiv.HPMC muaj peev xwm tuav dej ruaj khov nyob rau hauv qhov kub thiab txias, txawm hais tias kev hloov pauv ntawm qhov kub thiab txias yuav cuam tshuam rau nws lub peev xwm tuav dej.Qee cov qib tshwj xeeb ntawm cov khoom tseem tuaj yeem ua haujlwm zoo nyob rau hauv qhov chaw kub kub.Hauv gypsum-based thiab tshauv-calcium-based khoom, cellulose ethers kuj ua lub luag haujlwm tseem ceeb hauv kev ua kom lawv lub sijhawm qhib thiab kev loj hlob ntawm lub zog.
Kev ua haujlwm zoo
Hydroxypropyl Methyl Cellulose (HPMC) tuaj yeem ua kom muaj zog thixotropic ntawm cov tshuaj khib nyiab, uas tso cai rau cov mortar uas muaj peev xwm los tiv thaiv sagging zoo, yog li txhim kho kev tsim kho, tshwj xeeb tshaj yog thaum lub tsev ntawm phab ntsa.Qhov zoo sag kuj ntawm lub mortar txhais tau hais tias yuav tsis muaj slippage thaum lub mortar yog tsim nrog ib tug txiav txim siab thickness;rau cov pobzeb pasting project, nws txhais tau hais tias cov vuas pasted rau phab ntsa yuav tsis raug tshem tawm vim lub ntiajteb txawj nqus.
