Kev sib raug zoo ntawm putty thiab latex xim yog cov tawv nqaij thiab plaub hau. "Yog tsis muaj tawv nqaij, yuav tsis muaj plaub hau." Lub sijhawm ntawd, peb tau npaj lub tswvyim ntawm "xya qhov chaw ntawm putty thiab peb feem ntawm cov xim", qhia txog qhov tseem ceeb ntawm putty. Txawm li cas los xij, ntau lub tuam txhab pleev xim pleev xim, cov tsim tawm, thiab cov tsev tsim kho tsis paub txog qhov tseem ceeb ntawm putty. Lawv yuam kev xav tias putty tsuas yog rau qib thiab qib. Nws yog ib qho khoom siv rau cov xim latex. Kev tsim khoom yog yooj yim heev. Ib tug tov khoom yog txaus. Stirring, kev tsim kho tsis yog tus qauv, Kuv xav tias ntev npaum li nws tuaj yeem muab tso rau ntawm phab ntsa, nws tuaj yeem raug khawb. Yog li ntawd, muaj ntau yam teeb meem nrog cov pleev xim rau ntawm phab ntsa sab hauv thiab sab nrauv, xws li cov teeb meem ntawm cov hmoov tshem tawm, tawg, efflorescence, thiab tawg. teeb meem, teeb meem daj, thiab lwm yam. Kev cuam tshuam loj rau qhov zoo ntawm qhov project thiab ua rau poob zoo heev. Cov lus nug no ua rau txhua tus paub txog qhov teeb meem loj. Tshwj xeeb tshaj yog txij li thaum lub tsev sab nrauv thermal rwb thaiv tsev mortar tau nrov thoob plaws lub tebchaws, cov kab nrib pleb hauv qhov kawg tau dhau los ua kev txhawj xeeb ntawm cov neeg cog lus, tus neeg cog lus, kev tsim kho, cov chaw tsim khoom, thiab lwm yam. Thaum muaj qhov tawg, ob tog yuav shirk lub luag haujlwm ntawm ib leeg. Raws li kev xyaum ntau lawm thiab kev tsim kho, raws li cov duab ntawm cov kab nrib pleb, peb muaj peev xwm pib delineate tog lub luag hauj lwm rau lub tawg tsim thiab muab ib tug zoo kev daws teeb meem.
Cov kab nrib pleb hauv tsev tuaj yeem muab faib ua plaub hom:
1. Cov kab nrib pleb hauv phab ntsa: Cov kab nrib pleb tsis sib xws nrog kev hloov ntawm lub hauv paus. Kev faib tawm tsis tu ncua ntawm phab ntsa sab nrauv: nws yog kab rov tav faib. Tshem tawm cov kab nrib pleb thiab saib dua; cov kab nrib pleb saum toj no yog tshwm sim los ntawm kev sib haum xeeb thiab deformation ntawm phab ntsa. Kev daws: ⑴. Yog tias lub tsev tau teeb tsa thiab deforming, tsis txhob ua haujlwm kho nws. ⑵ Ntau yam kev daws teeb meem yuav tsum tau txais los kho raws li cov duab thiab qhov ntom ntom ntawm cov kab nrib pleb. Nws tuaj yeem kho tau los ntawm slotting lossis ntxiv cov ntaub mesh, tab sis nws yuav tsum tau kho nrog high-elastic putty.
2. Cracks nyob rau hauv lub stucco txheej: lub leveling mortar tsis saj zawg zog txaus, thiab qhov tiav qhia tau hais tias kuj loj tortoise tawg, uas yog feem ntau sib npaug. Siv high-elastic putty los yog ob-tivthaiv hloov tau yooj yim putty rau ib tug tag nrho batch los yog kho nyias. Cov kab nrib pleb hauv txheej rwb thaiv tsev: Feem ntau, cov kab nrib pleb tsis sib xws yog ntau dua. Nws yog tshwm sim los ntawm ntau yam xws li shrinkage thiab deformation ntawm benzene board los yog polystyrene hais, thiab kev tsim kho ntawm cov ntaub mesh thiab mortar tsis raug. Kev daws yuav tsum tau txiav txim siab raws li qhov loj thiab kev faib tawm ntawm cov kab nrib pleb. Yog tias nws loj heev, nws yog ib qho tsim nyog yuav tau ntxiv cov ntaub mesh thiab siv cov mortar hloov tau los nias nws. Yog tias nws tsis loj, siv ob lub ntsiab lus hloov tau yooj yim los sau nws lossis kho nws cais. Cracks nyob rau hauv lub putty txheej: feem ntau tshwm li zoo tortoise kab nrib pleb, uas yog sib npaug zos faib. Nco ntsoov tias nws tsis yog seam los yog nplej, thiab muaj qhov sib txawv ntawm cov nplej thiab seam.
Hauv qab no peb tsuas yog tham txog kev tawg ntawm putty txheej. Yog hais tias lub putty txheej yog tuab heev, tawg yuav tshwm sim. Feem ntau, lub thickness ntawm lub putty yog 1-2mm, thiab feem ntau tsis ntau tshaj 3 hli. Qee cov phab ntsa sab hauv thiab sab nrauv muaj qhov yuam kev ntau npaum li 3-5 cm nyob rau hauv qhov flatness ntawm lub hauv paus nto. Yog hais tias lawv tag nrho cov leveled nrog putty hmoov, lawv yeej yuav tawg. mortar yuav tsum tau siv rau leveling. Qhov loj dua qhov yuam kev, lub coarser cov xuab zeb ntawm lub mortar yog xav tau. Lub hauv paus txheej yuav tsum tau leveled nrog masonry mortar, thiab cov mortar hloov tau yuav tsum tau siv rau leveling. Yog hais tias tus nqi ntawm inorganic binder ( tshauv calcium hmoov, cement) ntau dhau lawm, lub zog kuj yuav ua rau tawg. Feem ntau, cov kab nrib pleb tshwm nyob rau hauv lub waterproof putty ntawm sab hauv thiab sab nrauv phab ntsa. Yog tias cov kua qaub calcium hmoov thiab cov cement ntxiv tshaj 50 feem pua, lub zog ntawm putty yuav siab dhau, qhov ua tiav yuav nyuaj thiab nkig, thiab cov kab nrib pleb yuav yooj yim tshwm sim. Yav dhau los, cov kua nplaum tau siv nyob rau hauv feem ntau ntawm peb lub teb chaws (tsis yog 107 kua nplaum, vim 107 kua nplaum raug txiav tawm vim muaj teeb meem kev tiv thaiv ib puag ncig), ntxiv rau cov hmoov qub lossis cov kua nplaum rau sab nrauv phab ntsa ntxiv rau cov cement dawb, nws yog ib qho yooj yim los ua hmoov tshem tawm thiab tawg. Lub plaster txheej ntawm sab hauv thiab sab nrauv phab ntsa yog xoob thiab plua plav. Yog hais tias nws tsis tau daws, tag nrho batch ntawm putty yuav khi ib txheej ntawm hmoov rau saum npoo, uas yog ib qho yooj yim rau bulge thiab txheej. Yog hais tias lub suab txawv thaum nws yog khob ntawm tes, cov kab nrib pleb yuav tshwm sim maj mam nrog kev hloov ntawm sab nraud txias thiab kub kub, thiab cov kab nrib pleb yuav qhib rau hauv qhov chaw hollow. Yog tias koj qhib qhov tawg, koj yuav pom tias muaj ob txheej ntawm putty thiab hauv qab ntawm phab ntsa, thiab ib txheej ntawm plua plav hauv nruab nrab. Cov txheej txheej putty tsis nruj ua ke nrog txheej stucco, lub zog sib txuas tsis txaus, thiab cov kab nrib pleb yog bulging.
