Hydroxypropyl methylcellulose (HPMC) ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ib puag ncig ntawm cov ntaub ntawv tsim kho.
Txhim kho kev siv hluav taws xob zoo: HPMC tuaj yeem txhim kho cov khoom siv thermal thiab mechanical ntawm plaster mortar, txhim kho thermal rwb thaiv tsev los ntawm kev nce qhov porosity ntawm cov khoom, thiab yog li txo kev siv hluav taws xob.
Cov peev txheej rov ua dua tshiab: Kev tsim cov HPMC yog ua los ntawm cov cellulose ntuj, uas yog cov peev txheej rov ua dua tshiab thiab muaj kev cuam tshuam tsawg dua rau ib puag ncig dua li ntau cov khoom siv tshuaj lom neeg.
Kev puas tsuaj ntawm cov khoom siv: HPMC yog cov khoom siv uas lwj tau, uas txhais tau tias nws tuaj yeem lwj tau raws li ntuj tsim thaum kawg ntawm nws lub neej ua haujlwm, txo qhov cuam tshuam ntawm cov khib nyiab tsim kho rau ib puag ncig.
Txo cov pa phem VOC: Siv HPMC hauv cov txheej txheej tuaj yeem txo qhov kev tso tawm ntawm cov organic sib xyaw (VOCs), txhim kho huab cua hauv tsev thiab txo qhov cuam tshuam rau ib puag ncig.
Txhim kho kev tsim kho kom zoo thiab ruaj khov: HPMC tuaj yeem txhim kho kev ua tau zoo ntawm cov ntaub ntawv tsim kho, txo kev ua haujlwm dua thiab kev kho, yog li txuag cov peev txheej thiab txo cov khib nyiab.
Txhim kho kev ruaj khov: HPMC txhim kho kev ruaj khov ntawm cov mortar, txuas ntxiv lub neej kev pabcuam ntawm cov tsev, txo qhov xav tau kev saib xyuas thiab kho, thiab yog li txo cov peev txheej siv.
Txhim kho kev khaws dej: HPMC, ua tus neeg sawv cev khaws dej, tuaj yeem txo qhov dej evaporation, xyuas kom muaj dej noo zoo dua ntawm cov cement, txhim kho kev nplaum, ua rau cov khoom muaj zog thiab ruaj khov dua, thiab txo cov khoom pov tseg.
Txhim kho kev nplaum: HPMC txhim kho kev nplaum ntawm cov khoom siv cement thiab gypsum rau ntau yam khoom siv, txo qhov kev pheej hmoo ntawm kev ua tsis tiav, thiab txo qhov zaus ntawm kev kho thiab hloov pauv, yog li txuag cov peev txheej.
Txo cov pa phem rau ib puag ncig: HPMC ua tau raws li cov qauv ntawm cov tshuaj 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 tsim kho tshiab.
Txhawb kev txhawb nqa cov ntaub ntawv tsim vaj tsev ntsuab: Daim ntawv thov HPMC txhawb nqa kev txhawb nqa thiab kev siv cov ntaub ntawv tsim vaj tsev ntsuab, ua raws li cov cai tiv thaiv ib puag ncig thiab kev txhim kho kev paub txog ib puag ncig rau pej xeem.
HPMC tsis yog tsuas yog txhim kho kev ua tau zoo thiab kev tsim kho kom zoo ntawm cov ntaub ntawv siv hauv tsev xwb, tab sis kuj txo qhov cuam tshuam tsis zoo rau ib puag ncig thiab txhawb nqa kev txhim kho kev lag luam tsim kho kom ruaj khov.
