Dej khaws cia los ntawm hydroxypropyl cellulose yog ib qho ntawm cov khoom tseem ceeb ntawm hydroxypropyl methylropeyl cellulose. Yam xws li cua kub thiab cua kub tuaj yeem cuam tshuam rau cov evaporation tus nqi ntawm noo noo hauv xis thiab gypsum raws li cov khoom lag luam. Yog li nyob rau hauv lub caij sib txawv, ntxiv hydroxypropyl methylculose ntawm tib tus nqi ntawm kev ua lag luam dej khaws cia muaj qee qhov sib txawv.
Feem ntau, ntau dua cov viscrotylropylulose, qhov zoo dua cov dej khaws cia rau thaum lub viscosity tshaj 100,000 mpa.S. Ntau tshaj 100,000 viscosity ntawm hydroxypropylulose kom txhim kho cov dej khaws nyiaj los ntawm hydroxypropyl methylculose ntxiv.
Hauv kev tsim kho kom ntxaws tuaj yeem nce lossis txo tus nqi ntawm hydroxypropyl methyl cellulose, kho cov dej ua kom ruaj ntseg ntawm slurry. Hydroxypropyl methyl cellulose cov khoom lag luam tuaj yeem muaj txiaj ntsig zoo rau kev sib tuav dej ntawm cov kub. Nyob rau hauv qhov kub sov lub caij, tshwj xeeb tshaj yog cov huab cua sov thiab cov nyias txheej kub thiab cov lus thov kom zoo me me los txhim kho cov dej khaws cia.
Zoo siab ntawm kev sib txawv ntawm hydroxypropyl cellulose, nws tuaj yeem npaj cov pa dej, nws tuaj yeem npaj cov pa roj av, nws tuaj yeem ua kom muaj kev nyab xeeb ntawm kev tiv thaiv kev nyab xeeb, ncav cuag cov dej noo.
Zoo siab ntawm hydroxypropyl cellulose tuaj yeem tso tawm hauv lub hauv paus ntev, thiab inorganic raws li cov khoom siv ntub dej, thiab ua kom cov khoom sib xyaw ua ke, kom paub meej tias cov khoom sib raug zoo thiab lub zog compressive. Yog li ntawd, hauv kev siv kub lub caij ntuj sov, txhawm rau kom ua tiav cov tshuaj kom muaj txiaj ntsig, nws yuav tshwm sim los ntawm cov lus nug tsis txaus, tsis muaj qhov tsis txaus, tab sis kuj ntxiv cov neeg ua haujlwm tsim teeb meem. Thiab ib yam li cov tee kub, tuaj yeem txo cov dej hydroxypropyl methylropulose ntxiv, thiab tuaj yeem ncav cuag tib cov nyhuv khaws cia.
