Hydroxypropylmethylcellulose (HPMC) yog cov khoom siv hluav taws xob ntau yam siv dav hauv kev tsim kho kev lag luam.Nws yog cov khoom tsis muaj tshuaj lom, tsis muaj ntxhiab, pH ruaj khov los ntawm kev qhia hydroxypropyl thiab methyl pawg rau hauv ntuj cellulose.HPMC muaj nyob rau hauv ntau qib nrog sib txawv viscosities, particle loj thiab qib hloov.Nws yog cov dej-soluble polymer uas tuaj yeem tsim cov gels ntawm qhov siab, tab sis tsis muaj kev cuam tshuam me me los yog tsis muaj kev cuam tshuam rau rheology ntawm dej ntawm qhov tsis tshua muaj siab.Kab lus no tham txog kev siv HPMC hauv ntau yam khoom siv.
Kev siv ntawm HPMC hauv plastering thiab rendering
Kev tsim kho vaj tse yuav tsum tau txhim kho qhov chaw ntawm phab ntsa, pem teb thiab qab nthab.HPMC tau ntxiv rau gypsum thiab plastering cov ntaub ntawv los txhim kho lawv cov kev ua haujlwm thiab adhesion.HPMC txhim kho qhov smoothness thiab sib xws ntawm plaster thiab plastering cov ntaub ntawv.Nws ua rau kom muaj peev xwm khaws dej ntawm cov khoom sib tov, cia lawv ua raws li cov phab ntsa lossis hauv pem teb.HPMC kuj tseem pab tiv thaiv kom tsis txhob shrinkage thiab tawg thaum lub sij hawm kho thiab ziab, ua kom lub zog ntawm cov txheej.
Daim ntawv thov ntawm HPMC hauv pobzeb nplaum
Pobzeb nplaum yog ib feem tseem ceeb ntawm kev tsim kho niaj hnub.HPMC yog siv rau hauv cov nplais nplaum los txhim kho lawv cov adhesion, dej tuav thiab kev tsim kho.Ntxiv HPMC rau daim ntawv nplaum ua kom lub sijhawm qhib ntawm cov nplaum, muab cov neeg siv sijhawm ntxiv los hloov kho ua ntej cov pobzeb teeb.HPMC kuj ua rau kom qhov yooj yim thiab ua haujlwm ntev ntawm txoj hlua khi, txo qhov kev pheej hmoo ntawm delamination lossis tawg.
Daim ntawv thov ntawm HPMC hauv tus kheej-leveling compounds
Self-leveling tebchaw yog siv rau theem pem teb thiab tsim ib tug du, txawm nto rau installation ntawm flooring cov ntaub ntawv.HPMC tau ntxiv rau tus kheej-leveling tebchaw los txhim kho lawv cov dej ntws thiab qib theem.HPMC txo qhov pib viscosity ntawm qhov sib tov, ua kom yooj yim rau kev thov thiab txhim kho qib.HPMC tseem ua rau kom cov dej tuav ntawm qhov sib tov, ua kom muaj zog dua ntawm cov khoom siv hauv pem teb thiab cov substrate.
Kev siv HPMC hauv caulk
Grout yog siv los sau qhov khoob ntawm cov vuas, pob zeb ntuj lossis lwm yam ntaub ntawv hauv pem teb.HPMC tau ntxiv rau kev sib koom ua ke los txhim kho nws txoj kev tsim kho thiab ua haujlwm ntev.HPMC ua kom cov viscosity ntawm cov khoom sib xyaw ua ke, ua kom yooj yim rau kev sib kis thiab txo qis shrinkage thiab tawg ntawm cov khoom muab tub lim thaum kho.HPMC kuj tseem txhim kho qhov adhesion ntawm qhov muab tub lim rau hauv lub substrate, txo qhov kev pheej hmoo ntawm yav tom ntej qhov khoob thiab tawg.
HPMC hauv cov khoom siv gypsum
Gypsum-based khoom, xws li plasterboard, qab nthab vuas thiab rwb thaiv tsev boards, yog dav siv nyob rau hauv kev tsim kho kev lag luam.HPMC yog siv rau hauv cov khoom siv gypsum los txhim kho lawv cov kev ua haujlwm, teeb tsa lub sijhawm thiab lub zog.HPMC txo cov dej xav tau ntawm cov qauv tsim, tso cai rau cov ntsiab lus siab dua, uas ua rau kom muaj zog thiab ua haujlwm ntev ntawm cov khoom tiav.HPMC kuj tseem txhim kho qhov adhesion ntawm gypsum hais thiab cov substrate, ua kom muaj kev sib raug zoo.
nyob rau hauv xaus
Hydroxypropylmethylcellulose (HPMC) yog ntau yam polymer siv nyob rau hauv ntau yam khoom siv.HPMC txhim kho kev ua tau zoo ntawm gypsum thiab plastering cov ntaub ntawv, pobzeb nplaum, tus kheej-leveling compounds, grouts thiab gypsum-based khoom.Kev siv HPMC hauv cov ntaub ntawv no txhim kho kev ua tau zoo, adhesion, dej tuav thiab kav ntev.Yog li, HPMC pab tsim kom muaj zog, ruaj khov dua, cov khoom siv lub tsev ntev ntev uas ua tau raws li qhov xav tau ntawm cov qauv niaj hnub no.
