Nrog rau kev txhim kho txuas ntxiv ntawm cov cuab yeej siv niaj hnub no, Sab Nraud Rwb Thaiv Tsev thiab Finish System (EIFS) tau dhau los ua ib qho kev daws teeb meem tseem ceeb hauv thaj chaw ntawm lub tsev txuag hluav taws xob. Txhawm rau txhim kho kev ua tau zoo ntawm EIFS, daim ntawv thov ntawmHydroxypropyl methylcellulose (HPMC)tau dhau los ua qhov tseem ceeb. HPMC tsis tsuas yog txhim kho kev tsim kho kev ua tau zoo, tab sis kuj tseem txhim khu kev ruaj ntseg thiab txuag hluav taws xob ntawm lub cev.
Lub hauv paus ntsiab lus ua haujlwm thiab cov teeb meem ntawm EIFS
EIFS yog ib qho kev sib xyaw ua ke uas sib xyaw ua ke sab nrauv phab ntsa rwb thaiv tsev thiab ua tiav cov haujlwm. Nws feem ntau suav nrog rwb thaiv tsev vaj huam sib luag, cov nplaum nplaum, cov ntaub nplaum ntxiv, cov txheej txheej thiab cov txheej txheem zoo nkauj. EIFS muaj cov thermal rwb thaiv tsev zoo thiab cov yam ntxwv ntawm lub teeb yuag, tab sis nws kuj tseem ntsib qee qhov teeb meem hauv kev siv cov tswv yim, xws li kev siv cov nplaum tsis txaus, txheej txheej tawg, thiab kev nqus dej ntau dhau. Cov teeb meem no cuam tshuam ncaj qha rau tag nrho cov durability ntawm lub system. kev sib deev thiab kev zoo nkauj.
Kev ua haujlwm yam ntxwv ntawmHPMC
HPMC yog ib qho kev ua tau zoo ntawm cellulose ether paub txog nws cov thickening zoo heev, dej tuav thiab hloov kho cov khoom siv hauv tsev. Nws lub luag haujlwm tseem ceeb hauv EIFS suav nrog:
Txhim kho dej tuav: HPMC ua kom muaj peev xwm tuav tau dej ntawm cov ntawv khi thiab txheej txheej, txuas ntxiv lub sijhawm ua haujlwm, thaum ua kom cov ntaub ntawv cement-raws li cov khoom sib npaug ntawm cov txheej txheem hardening kom tsis txhob muaj lub zog txaus lossis tawg los ntawm kev poob dej sai.
Kev tsim kho kev ua tau zoo: HPMC txhim kho cov khoom rheological ntawm cov ntawv khi thiab ua kom nws cov kev tiv thaiv sag, ua rau cov txheej txheem yooj yim siv thiab muaj kev sib kis tau zoo, yog li txhim kho kev tsim kho thiab ua haujlwm zoo.
Txhim kho kev sib raug zoo zog: Kev faib tawm ntawm HPMC tuaj yeem ua kom zoo dua qhov viscosity thiab adhesion ntawm cov nplaum, ua kom muaj kev sib raug zoo ntawm cov rwb thaiv tsev thiab phab ntsa.
Txhim kho kev ua haujlwm tawg: Los ntawm kev ua kom yooj yim ntawm cov tshuaj khib nyiab, HPMC zoo tiv thaiv cov txheej txheem ntawm kev tawg vim qhov kub thiab txias los yog txheej txheej deformation.
Cov ntawv thov tshwj xeeb ntawm HPMC hauv EIFS
Hauv EIFS, HPMC feem ntau yog siv hauv cov hauv qab no:
Bonding mortar: Tom qab ntxiv HPMC, lub tsev cog khoom mortar muaj kev ua haujlwm zoo dua thiab ua kom zoo dua qub, kom ntseeg tau tias lub rwb thaiv tsev yuav tsis hloov thaum lub sijhawm tsim kho.
Txhim kho txheej txheej mortar: Ntxiv HPMC rau cov txheej txheem ntxiv tuaj yeem txhim kho qhov tawv thiab tawg tsis kam ntawm mortar, thiab tib lub sijhawm txhim kho cov nyhuv txheej ntawm fiberglass mesh.
Kho kom zoo nkauj txheej txheej: Cov dej khaws cia thiab thickening ntawm HPMC ua rau cov hniav txheej ntau dua thiab cov xim pleev xim zoo dua, thaum txuas lub sijhawm qhib thiab txo cov kev tsim kho.
Txhim kho kev ua haujlwm hauv tsev
Los ntawm kev siv HPMC hauv EIFS, lub tsev qhov kev ua tau zoo tau txhim kho thoob plaws lub rooj tsavxwm:
Txhim khu kev txuag hluav taws xob: Cov kev sib raug zoo ntawm cov ntaub ntawv rwb thaiv tsev thiab phab ntsa txo cov thermal txuas txuas, thiab kev faib tawm ntawm HPMC kom ntseeg tau tias muaj kev ncaj ncees thiab thermal rwb thaiv tsev ua haujlwm ntawm mortar txheej.
Txhim kho durability: Cov mortar hloov kho thiab txheej yog ntau resistant rau cracking thiab weathering, ho expanding lub neej kev pab cuam ntawm lub system.
Txhim kho kev tsim kho kom zoo: HPMC txhim kho kev tsim kho kev ua tau zoo, ua rau kev tsim kho kom zoo dua qub thiab meej, thiab txo cov nqi rov ua dua.
Optimized zoo li zoo: cov hniav txheej yog flatter thiab cov xim yog sib xws, ua rau lub tsev zoo nkauj dua.
Raws li ib qho tseem ceeb additive nyob rau hauv EIFS,HPMCpab txhim kho lub system nrog nws cov kev ua tau zoo heev, muab cov kev daws teeb meem zoo thiab kav ntev rau cov tsev niaj hnub txuag hluav taws xob. Nyob rau hauv lub neej yav tom ntej, raws li kev tsim kho kev lag luam txuas ntxiv nce nws cov kev xav tau rau kev ua haujlwm siab thiab kev ruaj khov, daim ntawv thov kev cia siab ntawm HPMC hauv EIFS yuav yog qhov dav dua.
