Hydroxypropyl methyl cellulose ether rau qhuav tov npaj tov mortar

Nyob rau hauv qhuav sib tov npaj tov mortar, cov ntsiab lus ntawm HPMCE yog tsawg heev, tab sis nws muaj peev xwm txhim kho cov kev ua tau zoo ntawm ntub mortar. Tsim nyog xaiv ntawm cellulose ether nrog ntau yam, txawv viscosity, txawv particle loj, txawv viscosity degree thiab ntxiv npaum li cas muaj feem xyuam rau kev ua hauj lwm ntawm qhuav mortar. Tam sim no, ntau cov masonry thiab plastering mortar dej tuav kev ua tau zoo tsis zoo, ob peb feeb yuav tshwm sim me ntsis dej slurry sib cais. Kev tuav dej yog ib qho cuab yeej tseem ceeb ntawm Methyl cellulose ether, uas tseem muaj kev txhawj xeeb los ntawm ntau lub tuam txhab mortar qhuav hauv Suav teb, tshwj xeeb tshaj yog nyob rau sab qab teb qhov kub siab dua. Cov yam ntxwv cuam tshuam rau cov dej tuav ntawm cov khib nyiab qhuav suav nrog cov cellulose ether HPMC, viscosity ntawm cellulose ether HPMC, qhov zoo ntawm cov khoom thiab qhov kub ntawm ib puag ncig. Cellulose ether yog ib hom hluavtaws polymer ua los ntawm ntuj cellulose los ntawm kev hloov tshuaj. Cov dej-soluble cellulose ether plays lub luag haujlwm tseem ceeb hauv mortar hauv peb yam, ib qho yog cov dej tuav tau zoo, lwm qhov yog kev cuam tshuam ntawm mortar sib xws thiab thixotropy, thiab qhov thib peb yog kev cuam tshuam nrog cov cement. Kev tuav dej ntawm cov cellulose ether nyob ntawm qhov nqus dej ntawm lub hauv paus, muaj pes tsawg leeg ntawm mortar, thickness ntawm mortar, dej xav tau ntawm mortar thiab lub sijhawm teem sijhawm ntawm cov khoom siv. Cov dej tuav ntawm cellulose ether nws tus kheej los ntawm solubility thiab lub cev qhuav dej ntawm cellulose ether nws tus kheej.
