Hauv cov cement mortar thiab gypsum-based slurry, HPMC feem ntau ua lub luag haujlwm ntawm dej tuav thiab thickening.Nws tuaj yeem txhim kho txoj hlua khi thiab tiv thaiv pituitarism ntawm slurry.
Cov huab cua kub, cua kub thiab cua siab tshaj tawm cuam tshuam rau volatilization tus nqi ntawm cov dej hauv cement mortar thiab gypsum raws li cov khoom.
Nyob rau lub caij sib txawv, muaj qee qhov sib txawv ntawm cov dej tuav ntawm HPMC.Hauv kev tsim kho tshwj xeeb, cov dej tuav cov nyhuv ntawm slurry tuaj yeem hloov kho los ntawm kev nce lossis txo tus nqi ntawm HPMC ntxiv.Kev tuav dej ntawm methyl cellulose ether nyob rau hauv qhov kub thiab txias yog ib qho tseem ceeb qhia kom paub qhov zoo ntawm methyl cellulose ether.HPMC series cov khoom lag luam zoo tuaj yeem daws qhov teeb meem ntawm cov dej tuav hauv qhov kub thiab txias.
Nyob rau hauv lub caij kub kub, tshwj xeeb tshaj yog nyob rau hauv kub thiab qhuav cheeb tsam thiab nyias-txheej tsim nyob rau hauv tshav ntuj sab.High quality HPMC yuav tsum tau txhim kho cov dej tuav ntawm slurry.Nws tuaj yeem txhim kho lub peev xwm ntawm oxygen atom ntawm pawg hydroxyl los tsim ib daim ntawv cog lus hydrogen nrog ether daim ntawv cog lus.Ua dej dawb rau hauv cov dej khi, thiaj li tswj tau cov evaporation ntawm dej los ntawm huab cua kub.Cov dej khaws cia siab.
High-zoo cellulose HPMC tuaj yeem ua tau zoo sib xws thiab muaj txiaj ntsig zoo hauv cov cement mortar thiab gypsum-based khoom.Thiab qhwv tag nrho cov khoom siv los ua ib zaj duab xis ntub dej.Cov dej noo nyob rau hauv lub hauv paus txheej yog maj mam tso rau lub sij hawm ntev, thiab cov khoom inorganic gelling undergoes hydration cov tshuaj tiv thaiv.Li no kom ntseeg tau lub zog ntawm daim ntawv cog lus thiab compressive zog ntawm cov khoom.Yog li ntawd, nws yuav tsum tau tsim nyob rau hauv high kub lub caij ntuj sov kom ua tau dej tuav nyhuv.Nco ntsoov ntxiv cov khoom zoo HPMC raws li cov qauv, txwv tsis pub yuav muaj teeb meem zoo xws li dej tsis txaus.Tab sis nws kuj ua rau kev tsim kho nyuaj ntawm cov neeg ua haujlwm.Raws li qhov kub thiab txias poob, tus nqi ntawm HPMC tuaj yeem txo qis, thiab cov nyhuv tuav dej kuj tuaj yeem ua tiav.
