HydroxyPropyyl methylcellose (HPMC) yog ntau cov kev siv polymer ntau zog siv hauv kev tsim kho kev lag luam vim nws qhov tshwj xeeb. Qhov cellulose-derived compound tuaj yeem siv rau ntau yam khoom siv hauv tsev los pab txhim kho kev ua haujlwm thiab kav ntev.
Taw qhia rau hydroxyPropyyl Metthylcellulose (HPMC)
Kev txhais thiab cov qauv
Hydroxypropylencellulose yog ib nrab hluavtaws polymer muab tau los ntawm cellulose, lub ntsiab tivthaiv ntawm cov nroj tsuag phab ntsa. Cov qauv tshuaj ntawm HPMC koom nrog kev hloov ntawm hydroxyl pawg hauv cellulose nrog hydroxypropyl thiab methyl pawg.
Cov Khoom Siv Lub Cev
Solubility: HPMC tau ploj mus hauv dej thiab cov kev daws teeb meem kom pom tseeb, ua kom haum rau ntau yam kev siv.
Zaj duab xis-tsim: nws muaj zaj duab xis zoo heev-tsim thiab tuaj yeem tsim cov nplaum thiab cov yeeb yaj kiab hloov tau.
Daim ntawv thov hauv cov ntaub ntawv tsim
1. Cug thiab cov khoom noj raws li cov txiv ntoo
A. Txhim kho kev ua haujlwm
HPMC feem ntau ntxiv rau cov khoom lag luam mortars thiab cov cement-raws los txhim kho kev ua haujlwm. Nws ua raws li dej tuav tus neeg sawv cev, tiv thaiv kom tsis txhob dej sai sai thaum lub teeb txheej txheem. Qhov no ua rau muaj kev siv taus zoo dua thiab yooj yim daim ntawv thov.
b. Nce adhesion
Ntxiv HPMC rau tshuaj khib kev hloov kho cov nplaum rau ntau yam ntawm cov substrates. Nws tsim cov yeeb yaj kiab nyias nyias nyob saum npoo, txhawb kom zoo dua kev sib raug zoo ntawm cov tshuaj khib thiab txheej.
C. Txo cov sagging
Nyob rau hauv cov ntawv thov ntsug, xws li cov vuas luaj ceramic, HPMC pab txo sagging lossis slumping ntawm lub cug. Qhov no yog qhov tshwj xeeb tshaj yog thaum ua haujlwm ntawm phab ntsa lossis lwm qhov chaw ntsug.
2. Pobzeb Adhesive
A. Ncua Sijhawm Qhib
Pobzeb Cov Ntawv Qhia Txog HPMC muaj lub sijhawm qhib sijhawm ntev dua, muab cov hluav taws xob ntxiv rau cov nplais ua ntej cov nplaum ua ntej cov nplaum. Qhov no yog qhov tseem ceeb rau kev ua tiav qhov kev teeb tsa meej.
b. Txhim Kho Cov Khoom Siv Dej
HPMC cov khoom siv dej-khaws cia pab txo cov vuas nqus dej, tiv thaiv cov nplaum los ntawm kev ziab khaub ncaws ua ntej ntxov thiab ua kom pom tseeb.
3. Stucco thiab Plastering
A. tawg tsis kam
HPMC pab kom tau kev hloov pauv tau ntxiv thiab cohesion ntawm cov plasters thiab plasters, txo qhov ntxim nyiam ntawm cov kab nrib pleb. Qhov no yog qhov tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov sab nrauv uas cov khoom yog nthuav tawm huab cua hloov chaw sib txawv.
b. Nto kem
Qhov kev sib txuas ntawm HPMC pab txhim kho qhov smoopess ntawm plastered surfaces, muab ib qho txawm thiab ua kom zoo nkauj ua tiav.
4.Gypsum-based khoom
A. Txheej lub sijhawm tswj
Hauv Gypsum-based khoom xws li sib txuas sib txuas, HPMC yog siv los tswj lub sijhawm. Qhov no tso cai rau kev ua tiav zoo thiab kev smoothing ntawm cov nqaws ua ntej cov khoom hardens.
b. Txhim Kho Kev Ua Haujlwm
Zoo sib xws rau nws lub luag haujlwm hauv Mortars, HPMC txhim kho kev ua haujlwm ntawm cov khoom lag luam ntawm gypsum-based, ua rau lawv yooj yim rau lis thiab thov.
HydroxyPropyyl methylulose yog ib qho tseem ceeb ntxiv hauv kev tsim kho kev tsim kho thiab ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm ntau cov ntaub ntawv hauv tsev. Nws cov versatility hauv kev txhim kho kev ua haujlwm, adhesion thiab kav ntev ua rau nws xaiv thawj zaug ntawm cov kws sau thiab cov neeg ua haujlwm. Raws li thev naus laus zis kev nce qib, HPMC lub luag haujlwm hauv kev tsim kho tshiab yog qhov yuav nthuav dav, kev tsim kho cov kev ua lag luam ntau dua thiab ua haujlwm tau zoo dua.
