KimaCell® HPMC (Hydroxypropyl Methylcellulose) yog cov khoom siv ua haujlwm polymer uas siv dav hauv cov khoom siv hauv tsev. Nws yog tsuas yog siv los ua cov thickener, dej tuav tus neeg sawv cev, nplaum, lubricant thiab zaj duab xis-tsim tus neeg sawv cev. Nws ua lub luag haujlwm tseem ceeb hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov cement-based thiab gypsum-raws li cov ntaub ntawv, txhim kho kev ua tau zoo ntawm cov khoom siv hauv tsev.
1. Txhim kho dej tuav
Kev tuav dej yog ib qho tseem ceeb tshaj plaws ntawm HPMC hauv kev tsim cov ntawv thov. KimaCell® HPMC muaj peev xwm nqus dej thiab khaws cov dej noo hauv cov khoom sib xyaw. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov khoom xws li cov cement mortars, cov khoom siv plaster thiab pobzeb adhesives.
Thaum cov khoom cement lossis gypsum sib xyaw nrog dej, cov dej noo tau yooj yim absorbed los ntawm substrate los yog qhuav tej yam kev mob nyob rau hauv cov huab cua, ua rau lub cev qhuav dej thaum ntxov thiab cuam tshuam rau cov kev ua tau zoo ntawm cov tshuaj tiv thaiv hydration. HPMC tuaj yeem txuas ntxiv lub sijhawm hydration ntawm cov cement los ntawm kev tuav dej, kom ntseeg tau tias cov khoom yuav tsis qhuav tawm ntxov thaum lub sijhawm tsim kho, thaum kawg txhim kho lub zog thiab kev sib raug zoo. Rau cov cement mortars thiab gypsum-raws li cov khoom lag luam, cov dej tuav tau zoo kuj tsis txhob muaj teeb meem tawg thiab chalking.
2. Txhim kho kev ua haujlwm
Hauv kev tsim kho, kev ua haujlwm ntawm cov ntaub ntawv ncaj qha cuam tshuam rau kev tsim kho. KimaCell® HPMC txhim kho qhov ntws thiab kis tau ntawm cov ntaub ntawv xws li mortars, plasters thiab pobzeb adhesives los ntawm thickening thiab lubricating teebmeem, ua rau lawv yooj yim dua rau kev siv thiab siv thaum siv. Piv txwv li, ntxiv HPMC rau pobzeb nplaum tuaj yeem ua rau nws yooj yim dua rau khawb, txo txoj hlua thaum ua haujlwm, thiab ua kom smoothness.
Tsis tas li ntawd, HPMC yuav tsis ua kom lub ntsej muag nruj thaum kho qhov sib xws ntawm cov khoom, tso cai rau cov khoom siv kom muaj kev sib kis tau zoo, txo qis qis, thiab txhim kho kev tsim kho kom zoo.
3. Txhim kho adhesion
Adhesion yog ib qho tseem ceeb uas txiav txim siab qhov ua tau zoo ntawm cov khoom siv hauv tsev. KimaCell® HPMC ua kom cov viscosity thiab lubrication ntawm cov tshuaj khib lossis cov nplaum, ua rau nws zoo dua rau kev sib cuag nrog cov substrate thiab tsim cov txheej txheem sib txuas. Hauv cov khoom xws li cov nplais nplaum thiab cov neeg ua haujlwm sib txuas, kev taw qhia ntawm HPMC tuaj yeem txhim kho qhov adhesion ntawm cov khoom rau cov substrates sib txawv.
Rau cov khoom xws li pobzeb kua nplaum thiab cov hmoov putty, zoo adhesion txhais tau hais tias cov khoom yuav tsis yooj yim poob los yog tev tom qab kev tsim kho tiav, yog li ncua lub neej kev pab cuam ntawm lub tsev. Qhov no tsis yog tsuas yog txo cov nqi rov ua haujlwm xwb tab sis kuj tseem txhim kho tag nrho cov khoom zoo ntawm lub tsev.
4. Txhim khu kev ua haujlwm tawg
Kev tawg yog ib qho teeb meem tshwm sim hauv kev tsim kho thiab feem ntau tshwm sim los ntawm kev poob dej thaum ntxov lossis tsis sib npaug ntawm cov khoom siv. KimaCell® HPMC muaj peev xwm tiv thaiv kev poob dej ntxov ntxov thaum lub sij hawm hardening txheej txheem los ntawm nws cov dej tuav cov nyhuv, yog li txo qhov shrinkage tawg los ntawm dej poob. Ntxiv HPMC rau mortar, gypsum khoom thiab putty hmoov tuaj yeem cuam tshuam qhov tawg ntawm cov khoom thiab txhim kho cov kav ntev thiab kev zoo nkauj ntawm lub tsev.
5. Ua kom lub sij hawm tsim kho
Kev siv sijhawm txuas ntxiv (cov sijhawm qhib) yog qhov xav tau loj hauv kev tsim kho vaj tsev, tshwj xeeb tshaj yog thaum ua haujlwm ntawm thaj chaw loj. KimaCell® HPMC txuas ntxiv lub sijhawm ua haujlwm ntawm mortar thiab plaster cov khoom los ntawm nws qhov tshwj xeeb tuav dej thiab ua kom tuab, muab sijhawm rau cov neeg ua haujlwm ntau dua los kho thiab kho. Qhov no yog qhov tseem ceeb tshwj xeeb los xyuas kom muaj kev tsim kho kom zoo thiab txo cov khoom pov tseg.
Piv txwv li, thaum lub sij hawm txheej txheem ntawm cov pobzeb tso, ncua sij hawm qhib cia cov neeg ua haujlwm tau yooj yim kho qhov chaw ntawm cov vuas yam tsis muaj cov khoom ziab ntxov ntxov, ua rau cov khoom tsis muaj zog lossis xav tau kev rov ua haujlwm dua.
6. Txhim kho kev ua haujlwm tiv thaiv sag
Hauv kev tsim vaj tsev, cov khoom tiv thaiv sag ntawm cov ntaub ntawv tshwj xeeb yog qhov tseem ceeb los xyuas kom meej qhov kev tsim kho ntawm phab ntsa thiab qab nthab. KimaCell® HPMC txo cov sagging ntawm mortars, putties thiab pobzeb adhesives ntawm ntsug nto los ntawm nws thickening thiab nce viscosity khoom.
Qhov no feature yog tshwj xeeb tshaj yog haum rau scenes uas yuav tsum tau ntsug kev tsim kho xws li plastering thiab pobzeb nteg. Lub mortar los yog pobzeb nplaum ntxiv nrog HPMC tuaj yeem ua kom muaj zog adhesion thiab dai, tiv thaiv cov khoom los ntawm ntws los yog zawv zawg hauv cov txheej txheem tsim kho, yog li ua kom cov smoothness thiab zoo nkauj ntawm qhov chaw tsim kho.
7. Txhim khu khov-thaw tsis kam
Thaum cov khoom siv hauv tsev raug raug rau qhov chaw sab nraum zoov, lawv feem ntau ntsib lub voj voog khov-thaw los ntawm kev hloov pauv kub. Lub voj voog khov-thaw tuaj yeem ua rau micro-cracks kom nthuav tawm hauv cov khoom siv, cuam tshuam rau tag nrho cov qauv kev ruaj ntseg ntawm lub tsev. Los ntawm nws cov dej tuav tau zoo thiab cov khoom ua yeeb yaj kiab, KimaCell® HPMC tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm cov khoom siv, txo qhov kev txav dawb ntawm cov dej molecules hauv cov khoom, yog li txhim kho nws cov dej khov-thaw thiab txuas ntxiv lub neej kev pab cuam. khoom siv tsev.
8. Txhim kho tshuaj corrosion kuj
Cov khoom siv hauv tsev yuav raug ntau yam tshuaj thaum siv, xws li acids, alkalis, ntsev, thiab lwm yam. Cov tshuaj no tuaj yeem ua rau cov khoom siv thiab cuam tshuam rau lawv lub neej kev pab. KimaCell® HPMC nce cov khoom tiv thaiv rau cov tshuaj no vim nws cov tshuaj tsis muaj zog tshwj xeeb. Tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv tsis muaj dej tsis zoo thiab siv cov nplaum nplaum, kev taw qhia ntawm HPMC tuaj yeem txhim kho cov khoom siv tshuaj tiv thaiv corrosion, yog li tswj kev ua haujlwm ruaj khov hauv cov cheeb tsam tshuaj hnyav.
KimaCell® HPMC txhim kho kev ua tau zoo ntawm cov khoom siv hauv tsev los ntawm kev txhim kho cov dej tuav, txhim kho adhesion, txhim kho kev ua haujlwm thiab kev ua haujlwm tawg. Kev taw qhia ntawm no multifunctional polymer additive tsis tsuas yog txhim kho kev tsim kho yooj yim thiab kev pab lub neej ntawm cov ntaub ntawv hauv tsev, tab sis kuj pab txhim kho tag nrho cov khoom zoo thiab zoo nkauj ntawm lub tsev. Hauv kev tsim kho niaj hnub no, KimaCell® HPMC tau dhau los ua qhov tseem ceeb thiab tseem ceeb ntxiv, thiab nws txoj kev siv dav hauv cov khoom siv hauv tsev tau txhawb nqa kev tsim kho technology ntxiv.
