Hydroxypropyl methylcellulose (HPMC) yog lub hom phiaj dav dav siv polymer feem ntau siv hauv kev tsim kho kev lag luam.Nws cov khoom tshwj xeeb tso cai rau nws tsim cov ntawv cog lus ruaj khov nrog cov cement thiab mortar, ua rau nws muaj qhov tseem ceeb hauv ntau cov khoom siv hauv tsev.
Hydroxypropyl methylcellulose (HPMC) yog dab tsi?
HPMC yog ib qho hluavtaws polymer muab los ntawm cellulose, ib txwm tshwm sim hauv cov nroj tsuag.Nws yog feem ntau siv nyob rau hauv kev lag luam tshuaj thiab zaub mov ua cov thickener, emulsifier thiab stabilizer.Hauv kev tsim kho kev lag luam, nws yog siv los ua cov thickener, nplaum thiab dej tuav tus neeg sawv cev.
HPMC ua haujlwm li cas nrog cov cement thiab mortar?
Thaum ntxiv rau cov cement thiab mortar, HPMC ua raws li cov dej khaws cia.Nws nqus dej thiab tsim cov khoom zoo li gel uas pab txhim kho kev ua haujlwm thiab sib xws ntawm qhov sib tov.Qhov no ua rau cov cement thiab mortar yooj yim dua rau kev sib kis thiab ua haujlwm nrog, muab lub ntsej muag smoother thiab txo qhov kev pheej hmoo ntawm kev tawg thiab shrinkage.
Ntxiv nrog rau nws cov khoom tuav dej, HPMC tuaj yeem siv los ua cov ntawv khi hauv cov cement thiab mortar.Nws tsim kev sib raug zoo nrog lwm cov khoom xyaw, pab txhim kho tag nrho lub zog thiab kav ntev ntawm cov khoom kawg.Qhov no ua rau nws yog ib qho kev xaiv nrov rau cov ntawv thov uas xav tau lub zog siab, xws li kev tsim kho cov choj, cov tsev siab siab, thiab lwm yam kev ua haujlwm.
Dab tsi yog qhov txiaj ntsig ntawm kev siv HPMC hauv cov cement thiab mortar?
Siv HPMC hauv cov cement thiab mortar muaj ntau qhov zoo:
1. Txhim kho kev ua haujlwm zoo: HPMC pab txhim kho kev ua haujlwm thiab kev sib xyaw ua ke, ua kom yooj yim rau kev sib kis thiab siv.
2. Txo cov shrinkage thiab cracking: HPMC cov dej-retaining zog pab tiv thaiv shrinkage thiab cracking, ib qho teeb meem tshwm sim ntawm cov cement thiab mortar.
3. Ua kom muaj zog thiab ua haujlwm ntev: HPMC ua raws li kev khi, pab ua kom tag nrho lub zog thiab ua haujlwm ntev ntawm cov khoom kawg.
4. Txhim kho adhesion: HPMC tsim muaj kev sib raug zoo nrog lwm cov khoom xyaw, uas muaj txiaj ntsig zoo rau kev ua kom zoo dua ntawm cov cement txheej thiab mortar txheej.
5. Txhim kho huab cua tiv thaiv: HPMC pab txhim kho huab cua tsis kam ntawm cov cement thiab mortar, ua rau lawv tiv taus dej thiab huab cua hnyav dua.
nyob rau hauv xaus
Kev sib koom tes ntawm HPMC thiab Cement thiab Mortar yog kev koom tes tseem ceeb uas tuaj yeem muaj txiaj ntsig zoo rau kev tsim kho kev lag luam hauv ntau txoj hauv kev.Los ntawm kev txhim kho constructability, txo shrinkage thiab cracking, txhim kho lub zog thiab durability, txhim khu adhesion thiab ua rau huab cua tsis kam, HPMC pab tsim cov khoom siv hauv tsev zoo tsim nyog rau kev txhim kho cov txheej txheem niaj hnub no.Raws li kev tsim kho kev lag luam txuas ntxiv zuj zus thiab hloov zuj zus, kev sib koom tes ntawm HPMC thiab cov cement thiab mortar yuav ua lub luag haujlwm tseem ceeb hauv kev tsim kho lub neej yav tom ntej.
