Hydroxypropyl methylcellulose (HPMC) plays lub luag haujlwm tseem ceeb hauv kev txhim kho ib puag ncig kev ua haujlwm ntawm cov khoom siv hauv tsev.
Txhim kho kev siv hluav taws xob: HPMC tuaj yeem txhim kho cov thermal thiab mechanical zog ntawm plaster mortar, txhim kho thermal rwb thaiv tsev los ntawm kev ua kom cov porosity ntawm cov khoom, thiab yog li txo lub zog noj.
Cov peev txheej tauj dua tshiab: Kev tsim tawm ntawm HPMC yog ua raws li cov cellulose ntuj, uas yog cov khoom siv txuas ntxiv dua tshiab thiab tsis muaj kev cuam tshuam rau ib puag ncig ntau dua li ntau cov khoom siv tshuaj.
Biodegradability: HPMC yog cov khoom siv biodegradable, uas txhais tau hais tias nws tuaj yeem decomposed nyob rau hauv qhov kawg ntawm nws cov kev pab cuam lub neej, txo cov kev cuam tshuam ntawm kev tsim cov pov tseg rau ib puag ncig.
Txo VOC emissions: Siv HPMC hauv cov txheej txheej tuaj yeem txo qhov tso tawm ntawm cov organic sib txuas (VOCs), txhim kho huab cua hauv tsev thiab txo kev cuam tshuam ib puag ncig.
Txhim kho kev tsim kho kom zoo thiab ruaj khov: HPMC tuaj yeem txhim kho kev tsim kho ntawm cov khoom siv hauv tsev, txo kev rov ua dua thiab kho dua tshiab, yog li txuag cov peev txheej thiab txo cov khoom pov tseg.
Txhim khu kev ruaj khov: HPMC txhim kho qhov ua haujlwm ntawm cov mortar, txuas ntxiv lub neej kev pab cuam ntawm cov tsev, txo qhov xav tau kev saib xyuas thiab kho, thiab yog li txo cov peev txheej siv.
Txhim kho dej tuav: HPMC, ua tus neeg saib xyuas dej, tuaj yeem txo cov dej evaporation, ua kom cov dej zoo dua ntawm cov cement, txhim kho adhesion, ua kom cov khoom muaj zog thiab ruaj khov, thiab txo cov khoom pov tseg.
Txhim kho adhesion: HPMC txhim kho cov adhesion ntawm cement-based thiab gypsum-based khoom rau ntau yam substrates, txo qhov kev pheej hmoo ntawm kev ua tsis tiav, thiab txo qhov zaus ntawm kev kho thiab hloov, yog li txuag cov peev txheej.
Txo cov pa phem ib puag ncig: HPMC ua tau raws li cov qauv ntawm cov tshuaj ntsuab ntsuab thaum lub sijhawm tsim khoom, txo cov pa phem rau ib puag ncig, thiab ua raws li kev tiv thaiv ib puag ncig hauv kev lag luam ntawm cov khoom siv niaj hnub no.
Txhawb kev txhawb nqa cov khoom siv vaj tsev ntsuab: Daim ntawv thov ntawm HPMC txhawb nqa kev txhawb nqa thiab kev siv cov khoom siv vaj tsev ntsuab, ua raws li cov cai tiv thaiv ib puag ncig thiab txhim kho kev paub txog pej xeem ib puag ncig.
HPMC tsis tsuas yog txhim kho kev ua tau zoo thiab kev tsim kho ntawm cov khoom siv hauv tsev, tab sis kuj txo cov kev cuam tshuam tsis zoo rau ib puag ncig thiab txhawb kev tsim kho kom ruaj khov ntawm kev tsim kho kev lag luam.
