HydroxyPropyyl methylcellulose (HPMC)yog dej-soluble tsis muaj tseeb cellulose cellulose cellulose uas tau siv dav hauv kev ua haujlwm cov ntaub ntawv hauv tsev, tshwj xeeb tshaj yog cov khoom noj. Raws li kev ua haujlwm ntxiv, Kimacell® tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom noj khoom haus ntawm lub cev thiab tshuaj kho mob, thiab txhim kho lawv cov haujlwm, cov neeg kho mob thiab ua kom zoo nkauj thiab kav ntev.
1. Txhim kho kev tsim kho kev tsim kho
Cov nyhuv muaj txiaj ntsig zoo tshaj plaws ntawm HPMC yog los txhim kho kev tsim kho kev tsim kho ntawm cov khoom noj qabent-raws. Los ntawm kev kho cov viscosity ntawm cov cement muab tshuaj txhuam, HPMC tuaj yeem txhim kho kev ua haujlwm ntawm cov khoom siv, ua rau nws yooj yim dua thiab ua kom qeeb dua thaum tsim kho. Tshwj xeeb tshaj yog nyob rau hauv tus kheej-level cug, HPMC tuaj yeem tswj cov dej fws thiab dej los ntawm kev tsim kho lossis sagging thaum lub sijhawm tsim kho, yog li ua kom muaj kev ua kom ncaj ncaj. Tsis tas li ntawd, HPMC kuj muaj cov nyhuv zoo heev, uas tuaj yeem txo cov kev sib txhuam ntawm cov cuab yeej siv thiab cov ntaub ntawv, txuas ntxiv txhim kho kev tsim kho.
2. Txhim Kho Cov Dej Ua Haujlwm
HPMC ua si lub luag haujlwm ntawm cov dej muaj zog khaws cov neeg sawv cev hauv cov khoom siv Maas. Cov pab pawg hydrophilic nyob rau hauv nws cov qauv molecular tuaj yeem nqus tau cov dej thiab ncua qhov chaw tsis zoo ntawm cov dej. Cov nyhuv ceev no yog qhov tseem ceeb heev rau cov tshuaj tsw qab ntawm cov khoom siv Maas. Ntawm ib sab tes, HPMC tuaj yeem nthuav tawm thawj zaug thiab lub sijhawm zaum kawg ntawm cov slurry thiab muab cov dej num kom txaus rau kev hloov pauv; Ntawm qhov tod tes, nws lub peev xwm dej rov qab tuaj yeem txo qis kev pheej hmoo ntawm shrinkage backing thiab txhim kho qhov seem ruaj khov ntawm cov khoom thaum lub sijhawm ua kom tawv tawv. Hauv qhov kub thiab txias lossis qis dua ib puag ncig cov nyhuv HPMC tshwj xeeb tshaj yog tshwm sim los ntawm kev muaj teeb meem tsis muaj teeb meem.
3. Txhim Kho Kev Ua Haujlwm
HPMC muaj cov khoom ua neeg ua kom zoo thiab tuaj yeem txhim kho cov nplaum ntawm cov khoom noj kom zoo ntawm cov khoom siv xiss thiab substrates. Hauv cov ntaub ntawv xws li pobzeb cov nplaum thiab plaster mortars, kev sib ntxiv ntawm HPMC tuaj yeem txhim kho lub zog uas muaj zog ntawm cov khoom siv thiab xyuas kom lawv ruaj khov siv sijhawm ntev. Tsis tas li ntawd, HPMC tseem tuaj yeem ua cov yeeb yaj kiab ntom ntom ntom nti, txhim kho cov cua tsis kam thiab lub zog siv hluav taws xob.
4. Txhim Kho Cov Khoom Siv Cov Neeg Kho
Txawm hais tias HPMC yog cov khoom siv polymer polymer feem ntau yog me me, nws kuj muaj cov txiaj ntsig zoo ntawm cov khoom siv tshuab ntawm cov ntxhib. HPMC tuaj yeem txhim kho ntawm cov slurry thiab ua cov khoom siv hydration ntau dua li faib tawm, yog li kev txhim kho lub zog compressive thiab lub zog ntawm cov khoom siv. Ib qho ntxiv, cov nyhuv nruj ntawm HPMC kuj tseem tuaj yeem txo cov brittleness ntawm cov khoom thiab txhim kho nws cov kev tawg tsis kam.
5. Thov cov piv txwv
Hauv kev siv cov ntawv thov,HPMCYog dav siv nyob rau hauv tus kheej txoj kev nphua, pobzeb nplaum, siv lub tsho tshuaj tshuaj tua hluav taws thiab cov khoom siv. Piv txwv li, hauv kev coj tus kheej sib nraws, qhov ntxiv ntawm HPMC tuaj yeem txhim kho flui-saws kev ua haujlwm; Hauv cov nplais nplaum, HPMC cov dej khaws cia thiab ua kom cov khoom siv ua kom ntseeg tau; Hauv cov txheej txheej tiv thaiv dej, HPMC tuaj yeem muab cov dej ua kom zoo thiab ua kom muaj cov teebmeem zoo, yog li kev txhim kho kev sib khi ua haujlwm ntawm txheej.
Raws li kev sib ntxiv ntau ntxiv, HydroxyPropyyl methylpcellulose ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom ua haujlwm ntawm cov khoom siv Maas. Los ntawm kev tsim kho kom zoo, txhim kho cov dej ua ke, txhim kho cov khoom siv neeg kho tshuab, Kimacell® nohpmc muab cov khoom siv kev txhim kho muaj zog rau kev txhim kho tsev. Nyob rau hauv yav tom ntej kev tshawb fawb thiab kev siv, txheej txheem kev ua haujlwm ntawm HPMC hauv cov tshuab sib txawv tuaj yeem tshawb pom ntxiv kom ua tiav cov ntawv thov txuas ntxiv.
