Cov dej khaws cia ntawm hydroxypropyl cellulose yog ib qho ntawm cov khoom tseem ceeb ntawm hydroxyprropy cellulose. Yam khoom xws li cua kub, ntsuas kub thiab cua kub yuav cuam tshuam rau cov dej colatilization thiab gypsum-based khoom. Yog li ntawd, nyob rau lub caij sib txawv, muaj qee qhov sib txawv ntawm cov dej ua kom ruaj khov ntawm cov khoom lag luam nrog tib medroxypropyl cellulose ntxiv.
Feem ntau, cov viscrot ntawm hydroxypropyl cellulose, qhov zoo dua cov txiaj ntsig ntawm cov dej khaws cia yuav raug txo kom tsawg dua 100,000 mpa.S. Rau hydroxypropyl methyl cellulose nrog viscosity ntau tshaj 100,000, nws yog ib qho tsim nyog los nce tus nqi ntawm hydroxyprropy cellulose kom nce cov dej khaws cia.
Hauv kev tsim kho tshwj xeeb, cov dej khaws cov nyhuv khaws cia ntawm cov slurry tuaj yeem hloov kho los ntawm hydroxyprropy cellulose. HydroxyPropy cellaus cellulose cov khoom lag luam muaj txiaj ntsig zoo daws tau qhov teeb meem ntawm dej rov qab nyob rau hauv kub kub. Hauv cov caij nyoog siab, tshwj xeeb tshaj yog nyob rau hauv cov chaw kub thiab qhuav thiab nyias txheej hydroxypropyl methylrother yuav tsum tau txhim kho cov dej khaws cia ntawm cov slurry.
High-zoo hydroxypropal methyl cellulose muaj cov kev sib luag zoo heev. Nws cov methoxy thiab hydroxyprropoxy pawg yog tusyees faib raws txoj kev cellulose molecular. Nws tuaj yeem txhim kho cov pa atoms rau ntawm hydroxyl thiab Erether Bonds. Lub peev xwm ntawm cov dej hauv cov dej hydrogen hloov cov dej dawb rau hauv cov dej evaporation los ntawm huab cua huab cua siab thiab ua tiav cov dej kom siab dua.
High-zoo hydroxym methyl cellulose tuaj yeem ua kom muaj zog thiab ua rau cov duab ntub dej, thiab cov khoom noo nyob rau hauv lub hauv paus yuav raug tso tawm maj mam dhau lub sijhawm ntev. Cov kev siv dej ntawm cov dej ntws tawm nrog cov khoom sib xyaw ua ke, yog li ua kom muaj zog ntawm lub zog thiab lub zog compressive ntawm cov khoom. Yog li ntawd, nyob rau hauv high-kub lub caij ntuj sov, nyob rau hauv thiaj li yuav tsum tau ntxiv cov khoom siv hluav taws xob kom txaus, nws yog qhov tsis muaj zog, thiab tawg yuav tshwm sim vim qhuav. Cov teeb meem zoo xws li hollowing, hollowing, hollowing thiab ntog kuj nce ntxiv qhov nyuaj ntawm kev tsim kho rau cov neeg ua haujlwm. Raws li qhov ntsuas kub thiab txias, tus nqi ntawm hydroxypropyl cellulose ntxiv tuaj yeem txo qis, thiab tib cov nyhuv retentely tuaj yeem ua tiav.
