Hauv kev siv cov khoom siv hauv tsev, hydroxypropyl methyl cellulose HPMC yog cov khoom siv hauv tsev uas nquag siv,hydroxypropyl methyl celluloseyog siv dav hauv kev lag luam, thiab muaj ntau hom, hydroxypropyl methyl cellulose tuaj yeem muab faib ua Rau cov dej txias instant hom thiab kub yaj hom.
Cov dej txias tam sim HPMC tuaj yeem siv rau hauv cov hmoov putty, mortar, kua kua nplaum, kua xim thiab cov khoom siv tshuaj txhua hnub.Kub yaj HPMC feem ntau yog siv rau hauv cov hmoov qhuav qhuav thiab sib tov ncaj qha nrog cov hmoov qhuav rau daim ntawv thov, xws li putty hmoov thiab mortar, hydroxypropyl methylcellulose tuaj yeem siv dav los txhim kho kev ua haujlwm ntawm cov cement, gypsum thiab lwm yam khoom siv hauv tsev.Hauv cov cement-based mortars, nws txhim kho cov dej tuav, ncua sij hawm teeb tsa thiab qhib lub sijhawm, thiab txo cov dej ntws tawm.
Hydroxypropyl methylcellulose tuaj yeem siv rau hauv cov khoom siv hauv tsev sib xyaw thiab kev tsim kho, thiab cov qauv sib xyaw qhuav tuaj yeem sib xyaw nrog dej sai sai kom ua tiav qhov xav tau sib xws.Cellulose ether dissolves sai dua yam tsis muaj clumping.Propyl methyl cellulose tuaj yeem sib xyaw nrog cov hmoov qhuav hauv cov khoom siv hauv tsev, nws muaj cov yam ntxwv ntawm cov dej txias dispersion, tuaj yeem tshem tawm cov khoom zoo thiab ua kom cov sib tov zoo dua thiab zoo ib yam.Tsis tas li ntawd, nws txhim khu lubricity thiab plasticity, nce machinability, thiab pab txhawb cov khoom tsim.Txhim kho cov dej tuav, lub sijhawm ua haujlwm ntev dua, pab tiv thaiv kev ntws ntsug ntawm mortar thiab vuas, ua kom lub sijhawm txias thiab txhim kho kev ua haujlwm.
Hydroxypropyl methylcellulose txhim kho lub zog ntawm cov pobzeb nplaum, txhim kho cov kab nrib pleb thiab cov pob qij txha, tsis yog tsuas yog ua kom cov huab cua nyob hauv mortar xwb, tab sis kuj txo qis qhov muaj peev xwm ntawm kev tawg, nws tuaj yeem txhim kho cov tsos ntawm cov khoom thiab tuaj yeem ua rau muaj kev cuam tshuam zoo ntawm cov khoom siv. txhim khu kev tiv thaiv kev ua haujlwm ntawm cov nplais nplaum.
