HydroxyPropyyl methylulose feem ntau yog siv los ua ib qho tsis txaus siab nyob rau hauv kev tsim cov polyvinyl chloride, thiab yog lub ntsiab oomxiliary Tus neeg sawv cev rau npaj PVC los ntawm Kev Ncua Ntawv Polymerization. Hauv kev tsim kho cov txheej txheem ntawm kev tsim kho kev tsim kho, nws yog tsuas yog siv rau hauv kev tsim kho mechanized xws li phab ntsa tsev, plastering, caulking, thiab lwm yam; Tshwj xeeb tshaj yog nyob rau hauv kev ua kom zoo nkauj, nws yog siv los muab tshuaj txhuam cov vuas luaj, marble, thiab yas decorations. Nws muaj lub zog ua kom muaj zog siab thiab tuaj yeem txo cov cement. Cov. Nws yog siv los ua cov tuab hauv kev lag luam pleev xim, uas tuaj yeem ua rau txheej txheej thiab muag heev, tiv thaiv hmoov kom tshem tawm, thiab lwm yam.
Nyob rau hauv centent cortar thiab gypsum-raws li slurry, hydroxypropylulose cetting thiab thickenively, uas muaj peev xwm txhim kho txoj hlua khi thiab sag tiv thaiv ntawm cov slurry. 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 medroxypropylulose ntxiv. Hauv kev tsim kho tshwj xeeb, cov dej khaws cov nyhuv khaws cia ntawm cov slurry tuaj yeem hloov kho los ntawm nce lossis txo tus HPMC ntxiv. Cov dej rov qab ntawm methyl cellulose hauv qab cov kev mob siab yog qhov ntsuas qhov tseeb kom paub qhov zoo ntawm hydroxyprropyl cellulose ether. Zoo heev hydroxypropy methylulose cov khoom lag luam tuaj yeem daws cov teeb meem ntawm dej rov qab nyob rau hauv qhov kub siab. Hauv cov caij nyoog kub, tshwj xeeb tshaj yog nyob rau hauv cov chaw kub thiab qhuav thiab nyias txheej HPMC yuav tsum txhim kho cov dej khaws cia ntawm cov slurry.
High-zoo hydroxypropal methylcellose (HPMC) muaj kev sib txig zoo heev. Nws cov methoxy thiab hydroxyprropoxy pawg yog fortibuted raws cov cellulose molecular molecular, uas tuaj yeem nce cov pa atoms ntawm cov hydroxyl thiab Erether Bonds. Lub peev xwm los koom nrog dej los ua cov dej hydrogen hloov cov dej dawb los ntawm huab cua dav dav thiab ua tiav cov dej kom siab dua. Dej yuav tsum muaj rau kev co kom dej kom teeb tsa cov khoom noj xis xws li cement thiab gypsum. Qhov tseeb ntawm HPMC tuaj yeem ua kom cov dej noo hauv lub tshuaj khib nyiab ntev ntev kom lub sijhawm muaj peev xwm ua tau txuas ntxiv.
Tus nqi ntawm hydroxypropyl methylcellulose (HPMC) yuav tsum tau txais kev ua kom muaj dej kom txaus nyob ntawm:
Nqus ntawm lub hauv paus txheej
Sib xyaw ntawm cug
Tshuaj Khib Txheej Thickness
Tshuaj khib nyiab dej xav tau
Lub sij hawm teeb tsa cov khoom siv xis
HydroxyPropyfroseylulose tuaj yeem sib xyaw thiab ua kom muaj cov khoom siv ntub dej, thiab qhwv txhua lub zog ntawm cov khoom siv ntub dej thiab cov khoom siv ntub dej, thiab cov khoom siv ntub dej, thiab qhwv txhua lub zog ntawm cov khoom sib xyaw ua ke 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 dej khov kho, nws yuav tsum tau ntxiv lub zog zoo li cov khoom siv muaj txiaj ntsig zoo, nws yuav tsum tau tawg, kev ua haujlwm los ntawm kev ziab ntau dhau. Teeb meem, tab sis kuj tseem nce cov kev tsim kho cov neeg ua haujlwm. Raws li cov tee ntsuas kub, tus nqi ntawm cov dej HPMC ntxiv tuaj yeem txo qis qis, thiab tib cov nyhuv retentent tau ua tiav.
