Hydroxypropylroylrcellulose (HPMC) yog ib feem ntau ntau yam siv hauv kev tsim kho kev tsim kho. Nws yog cov tsis muaj tshuaj lom, tsis muaj kuab, phasless, ph-qis zog synthesized los ntawm kev qhia hydropypropyl thiab methyl pawg rau hauv lub ntuj cellulose. HPMC muaj nyob rau hauv ntau yam qhab nia nrog sib txawv viscosities, particle qhov ntau thiab tsawg thiab hloov chaw. Nws yog cov dej-soluble polymer uas tuaj yeem tsim cov gels ntawm siab siab tab sis muaj tsis zoo me me lossis tsis muaj kev cuam tshuam rau cov dej ntawm cov dej hauv qab. Kab lus no tham txog daim ntawv thov ntawm HPMC hauv ntau yam kev tsim kho.
Daim ntawv thov HPMC hauv plastering thiab rendering
Kev tsim kho ntawm cov tsev yuav tsum tau txhim kho cov khoom uas muaj cov teeb meem ntawm phab ntsa, cov plag tsev thiab qab nthab. HPMC tau ntxiv rau Gypsum thiab Plastering cov ntaub ntawv los txhim kho lawv cov haujlwm ua haujlwm thiab cov nplaum. HPMC txhim kho qhov smoothness thiab sib xws ntawm cov plaster thiab cov ntaub ntawv plastering. Nws nce cov dej-khaws lub peev xwm ntawm kev sib tov, tso cai rau kev ua raws li phab ntsa lossis pem teb. HPMC kuj tseem yuav pab tiv thaiv kom tsis txhob tawg thiab tawg thaum lub sij hawm kho thiab ziab, nce cov txheej txheem durability ntawm txheej.
Daim Ntawv Thov HPMC nyob rau hauv Pobzeb Adhesive
Pobzeb Cov Ntawv Qhia yog qhov tseem ceeb ntawm cov haujlwm tsim kho niaj hnub no. HPMC yog siv rau hauv cov nplais nplaum nplaum los txhim kho lawv cov nplaum, cov dej tuav cia thiab kev tsim kho. Ntxiv HPMC mus rau cov qauv nplaum kom loj hlob tau nce lub sijhawm qhib ntawm cov nplaum, muab cov khoom siv hluav taws xob ntxiv kom hloov ua ntej cov nplais teeb. HPMC kuj tseem nce qhov hloov tau thiab ruaj khov ntawm txoj kev sib koom ua ke, txo qhov kev pheej hmoo ntawm delamination lossis tawg.
Daim Ntawv Thov HPMC hauv Kev Ntsuas Tus Kheej
Kev siv tus kheej txoj kev sib xyaw ua ke yog siv los rau qib plag tsev thiab tsim kom du, txawm tias saum npoo rau kev teeb tsa cov ntaub ntawv hauv av. HPMC ntxiv rau kev ua kom tus kheej-ntsuas kom txhim kho lawv cov khoom ntws thiab ua kom muaj nuj nqis. HPMC txo qhov kev sib xyaw thaum xub thawj ntawm cov sib tov, ua rau nws yooj yim rau kev thov thiab txhim kho qib. HPMC kuj nce cov dej khaws cia ntawm cov sib tov, ua kom muaj zog zoo dua ntawm cov khoom siv hauv av thiab cov substrate.
Daim ntawv thov HPMC hauv Caulk
Cov grout yog siv los sau qhov khoob ntawm cov vuas luaj, cov pob zeb ntuj lossis lwm cov ntaub ntawv flooring. HPMC ntxiv rau kev sib txuas ua ke kom txhim kho nws txoj kev tsim kho thiab ua kom ntev. HPMC nce viscosity ntawm kev sib tov, ua rau nws yooj yim dua mus kis thiab txo cov shrinkage thiab tawg ntawm cov khoom siv rau khoom siv thaum lub sij hawm kho. HPMC kuj tau txhim kho cov nplaum ntawm cov muab tub lim rau cov substrate, txo qhov ntxim nyiam ntawm cov khoob ntawm cov khoob thiab tawg.
HPMC hauv Gypsum-based khoom
Gypsum-based khoom, xws li cov khoom siv plasterboard, qab nthab thiab rwb thaiv tsev laug cam, tau siv dav hauv kev tsim kho kev tsim kho. HPMC yog siv rau hauv gypsum raws los txhim kho lawv cov haujlwm, teeb tsa lub sijhawm thiab lub zog. HPMC txo cov dej yuav tsum tau ua rau cov tsim, tso cai rau cov ntsiab lus khib siab dua, uas ua rau muaj zog dua thiab cov khoom tiav ntawm cov khoom tiav. HPMC kuj tseem txhim kho cov nplaum ntawm cov gypsum hais thiab lub substrate, ua kom muaj kev sib cog lus zoo.
Hauv kev xaus
Hydroxypropylroylsylcellulose (HPMC) yog ib qho kev siv polymer ntau yam nyob hauv ntau yam kev tsim kho. HPMC txhim kho kev ua tau zoo ntawm Gypsum thiab cov ntaub ntawv plastering, cov nplaum sib txuas, cov khoom sib txuas tus kheej, grouts thiab gypsum-raws li cov khoom lag luam. Siv hpmc hauv cov khoom siv no txhim kho cov txheej txheem, cov nplaum, dej tuav thiab ua kom ntev. Yog li, HPMC pab tsim kom muaj zog dua, ntau dua cov ntaub ntawv ruaj khov, ua tau ntev ua tau raws li qhov xav tau ntawm kev ua lag luam tshiab.
