HydroxyPropyyl methylcellulose (HPMC) yog qhov sib txuas dav dav dav hauv kev tsim kho. Nws yog ib qho tsis-ionic cellulose cellulose siv los ua cov ntaub ntawv kho mob, cov khoom siv ua kom zoo nkauj, kev siv tus kheej sib txuas, ua kom muaj pob zeb. Lub viscosity ntawm HPMC yog qhov tseem ceeb hauv kev txiav txim siab nws cov kev ua tau zoo hauv kev kho cov ntawv thov. Hauv tsab xov xwm no, peb yuav kawm txog kev xaiv HPMC viscosity rau kev siv cov ntawv thov thiab nws cov kev cuam tshuam rau cov khoom lag luam kawg.
Viscosity ntsiab lus
Viscosity yog ib qho kev ntsuas ntawm cov kua dej tsis kam mus ntws. Nws txhais cov kev sib txhuam sab hauv ntawm cov kua thiab nws muaj peev xwm tiv taus deformation nyob rau hauv kev ntxhov siab. Rau HPMC, Viscosity txiav txim siab qhov sib xws ntawm kev daws teeb meem, uas cuam tshuam nws cov yam ntxwv thov thiab kev ua tau zoo ntawm cov khoom kawg.
HPMC Viscososity Xaiv
Qhov kev xaiv ntawm HPMC viscosity nyob ntawm lub chaw tsim khoom siv tshwj xeeb thiab cov khoom xav tau ntawm cov khoom kawg. Feem ntau hais lus, ntau dua qhov viscosity, cov tuab tuab ntawm kev daws teeb meem thiab qhov zoo dua cov dej khaws cia. Txawm li cas los xij, cov viscosities ntau dua kuj tshwm sim muaj kev nyuaj ntau dua, siv sijhawm ntau zaug, thiab qeeb qeeb txheej teeb lub sijhawm. Txo cov viscosity HPMC, tso rau ntawm qhov tod tes, tso cai rau lub sijhawm sib xyaw nrawm dua, tab sis tuaj yeem hloov kho dej kom yooj yim thiab cov khoom siv nplaum.
Cov kua nplaum
Nyob rau hauv cov nplais nplaum cov qauv, HPMC yog siv los ua cov tuab thiab dej khaws cia. Lub viscos ntawm HPMC nyob ntawm seb hom pobzeb nplaum, qhov loj thiab hom pobzeb, thiab sau cov nplais. Feem ntau hais lus, vwg cov khoom nplaum rau cov hom vuas loj yuav tsum tau sag viscosity HPMC yog qhov tsim nyog rau cov qauv viscc kom ua kom tau zoo thiab yooj yim dua. Cov.
Kev Ntsuas Tus Kheej
Kev Ntsuas Tus Kheej (SLC) yog siv rau qib thiab du tsis sib xws qhob ncig ua ntej txhim kho cov npoo av. Hauv SLC, HPMC ua raws li phau ntawv qhia thiab rheology kho dua tshiab. Qhov kev xaiv ntawm HPMC viscosity nyob ntawm cov dej ntws tau xav tau rau SLC. HPMC siab dua HPMC ua kom zoo siab leveling thiab sag tsis kam, thaum qis viscosity HPMC tso cai rau kev hloov pauv sai thiab yooj yim dua.
Cov cement-raws rendering thiab mortars
Cov neeg nplua nuj ua raws li cov plasters thiab cov neeg yuav khoom hauv phab ntsa thiab cov txheej txheem pem teb, kho dua tshiab thiab ua kom zoo dua. HPMC yog siv los ua cov tuab thiab dej khaws cia tus neeg sawv cev hauv cov qauv no. Qhov kev xaiv ntawm HPMC viscosity nyob ntawm cov txheej txheem xav tau thiab muaj txiaj ntsig, teeb tsa lub sijhawm, thiab cov khoom xav tau ntawm cov khoom kawg. HPMC siab dua HPMC muab cov dej ua kom zoo dua thiab cov khoom sib txuas lus, thaum qis viscosity HPMC nrawm nrawm thiab teeb tsa lub sijhawm thiab txhim kho cov txheej txheem.
Qhov kev xaiv ntawm HPMC viscosity yog qhov tseem ceeb rau kev ua tau zoo ntawm cov khoom tsim vaj tsev. Qhov zoo tshaj Viscosity nyob ntawm cov ntawv thov tshwj xeeb, cov khoom xav tau ntawm cov khoom kawg, thiab kev ua haujlwm. Txoj cai HPMC viscosity muaj cov ua haujlwm zoo heev, kev ua haujlwm zoo heev, nplaum thiab ua kom muaj nuj nqis thaum ua kom lub sijhawm ua haujlwm zoo thiab teeb tsa. Los ntawm kev xaiv cov viscosity, cov tub ceev xwm tsim kho tau tuaj yeem ua tiav kev ua tau zoo, ua kom ntev thiab zoo hauv lawv cov khoom
