Nrog rau kev txhim kho tas mus li ntawm cov thev naus laus zis niaj hnub no, Kev rwb thaiv tsev sab nraud thiab kev ua tiav (EIFS) tau dhau los ua qhov kev daws teeb meem tseem ceeb hauv kev txuag hluav taws xob hauv tsev. Txhawm rau txhim kho kev ua tau zoo ntawm EIFS, daim ntawv thov ntawmHydroxypropyl methylcellulose (HPMC)tab tom tseem ceeb zuj zus. HPMC tsis yog tsuas yog ua kom zoo dua qhov kev ua haujlwm ntawm kev tsim kho xwb, tab sis kuj tseem ua rau lub kaw lus ruaj khov thiab txuag hluav taws xob zoo dua.
Cov ntsiab cai ua haujlwm thiab cov teeb meem ntawm EIFS
EIFS yog ib lub kaw lus sib xyaw ua ke uas sib xyaw ua ke cov phab ntsa sab nraud rwb thaiv tsev thiab cov haujlwm tiav. Nws feem ntau suav nrog cov vaj huam sib luag rwb thaiv tsev, cov nplaum, cov ntaub mesh txhawb nqa, txheej txheej thiab cov txheej txheem kho kom zoo nkauj. EIFS muaj kev ua tau zoo rwb thaiv tsev zoo heev thiab cov yam ntxwv tsis hnyav, tab sis nws kuj ntsib qee qhov teeb meem kev siv tshuab hauv kev siv, xws li kev ua haujlwm tsis txaus ntawm cov nplaum, txheej tawg, thiab kev nqus dej ntau dhau. Cov teeb meem no cuam tshuam ncaj qha rau qhov ruaj khov ntawm lub kaw lus. poj niam txiv neej thiab kev zoo nkauj.
Cov yam ntxwv ntawm kev ua tau zoo ntawmHPMC
HPMC yog ib qho cellulose ether ua tau zoo heev uas paub txog nws cov khoom zoo heev uas ua rau tuab, khaws dej thiab hloov kho hauv cov ntaub ntawv tsim kho. Nws lub luag haujlwm tseem ceeb hauv EIFS suav nrog:
Kev khaws dej kom zoo dua: HPMC ua rau lub peev xwm khaws dej ntawm cov khoom sib txuas thiab txheej txheej zoo dua, ua kom lub sijhawm ua haujlwm tsim kho ntev dua, thaum xyuas kom meej tias cov khoom siv cement tau sib npaug thaum lub sijhawm ua kom tawv kom tsis txhob muaj zog txaus lossis tawg vim dej poob sai.
Kev txhim kho kev ua haujlwm ntawm kev tsim kho: HPMC txhim kho cov khoom rheological ntawm cov binder thiab ua rau nws tiv thaiv kev sag, ua rau cov txheej yooj yim rau kev thov thiab muaj kev sib kis zoo, yog li txhim kho kev ua haujlwm zoo thiab zoo ntawm kev tsim kho.
Kev sib txuas zoo dua: Kev faib tawm ntawm HPMC tuaj yeem ua kom zoo dua qhov viscosity thiab kev nplaum ntawm cov nplaum, tsim kom muaj kev sib txuas zoo ntawm lub rooj tsavxwm rwb thaiv tsev thiab phab ntsa.
Txhim kho kev tiv thaiv kab nrib pleb: Los ntawm kev ua kom muaj kev ywj pheej ntawm cov mortar, HPMC zoo tiv thaiv cov txheej kom tsis txhob tawg vim yog qhov kub hloov pauv lossis cov txheej hauv paus deformation.
Cov ntawv thov tshwj xeeb ntawm HPMC hauv EIFS
Hauv EIFS, HPMC feem ntau yog siv rau hauv cov hauv qab no:
Cov tshuaj nplaum sib txuas: Tom qab ntxiv HPMC, cov tshuaj nplaum sib txuas muaj kev ua haujlwm zoo dua thiab lo rau, kom ntseeg tau tias lub rooj tsavxwm rwb thaiv tsev yuav tsis txav thaum lub sijhawm tsim kho.
Cov txheej txheem txhawb nqa: Ntxiv HPMC rau txheej txheej txhawb nqa tuaj yeem txhim kho qhov tawv thiab tawg tsis kam ntawm cov mortar, thiab tib lub sijhawm txhim kho cov txheej txheem txheej ntawm cov fiberglass mesh.
Kev txheej txheem kho kom zoo nkauj: Cov yam ntxwv ntawm HPMC uas khaws dej thiab ua kom tuab ua rau cov txheej txheem kho kom zoo nkauj sib npaug dua thiab cov nyhuv pleev xim zoo dua, thaum txuas ntxiv lub sijhawm qhib thiab txo cov qhov tsis zoo ntawm kev tsim kho.
Kev txhim kho kev ua tau zoo ntawm lub tsev
Los ntawm kev siv HPMC hauv EIFS, kev ua haujlwm ntawm lub tsev tau txhim kho thoob plaws lub rooj tsavxwm:
Cov txiaj ntsig zoo dua ntawm kev txuag hluav taws xob: Kev sib txuas nruj ntawm lub rooj tsavxwm rwb thaiv tsev thiab phab ntsa txo qhov cuam tshuam ntawm tus choj thermal, thiab kev faib tawm sib xws ntawm HPMC ua kom muaj kev ncaj ncees thiab kev ua haujlwm rwb thaiv tsev thermal ntawm cov txheej mortar.
Txhim kho kev ruaj khov: Cov mortar thiab txheej txheej uas tau hloov kho lawm tiv taus kev tawg thiab huab cua, ua rau lub neej ua haujlwm ntawm lub kaw lus ntev dua.
Kev txhim kho kev tsim kho kom zoo dua: HPMC txhim kho kev ua haujlwm ntawm kev tsim kho kom zoo dua, ua rau cov txheej txheem tsim kho kom zoo dua thiab meej dua, thiab txo cov nqi kho dua tshiab.
Zoo nkauj dua: Cov txheej txheem kho kom zoo nkauj yog du thiab xim zoo nkauj dua, ua rau lub tsev zoo nkauj dua.
Ua ib qho khoom siv tseem ceeb hauv EIFS,HPMCpab ua kom lub kaw lus zoo tshaj plaws nrog nws qhov kev ua tau zoo heev, muab cov kev daws teeb meem zoo thiab kav ntev rau cov tsev txuag hluav taws xob niaj hnub. Yav tom ntej, thaum kev lag luam tsim kho txuas ntxiv nce nws cov kev xav tau rau kev ua tau zoo thiab kev ruaj khov, cov kev cia siab ntawm daim ntawv thov ntawm HPMC hauv EIFS yuav dav dua.
