Monolithic phab ntsa kho kom zoo nkauj, tsis hais hom khoom siv twg, yuav yeej ib txwm yeej ntawm kev ntseeg tau thiab ua haujlwm ntev ntawm qhov rov qab los. Tab sis nws yog deb ntawm ib txwm muaj kev ncaj ncees kom rhuav tshem cov txheej qub rau kev thov ib qho tshiab, yog li ntawd, kev ntsuas kev kho yuav tsum tsis txhob tso tseg. Feem ntau cov haujlwm ntawm hom no suav nrog kev sib tsoo plaster. Qhov kev ua haujlwm no yog dab tsi? Cov txheej txheem no yog nyob rau hauv qhov kev kho me me nyob rau hauv daim ntawv ntawm sealing ib tug puas tiav. Raws li, nws muaj nws tus yam ntxwv thiab nuances ntawm kev tua.
Sib tsoo nta
Cov txheej txheem no tuaj yeem muab piv rau ib feem ntawm cov primer lossis qhov chaw kho dua tshiab ntawm thaj chaw tsis raug. Tab sis yog tias qhov tsis txaus ntseeg tuaj yeem cuam tshuam nrog putty nrog lub teeb grout sib tov, uas tseem yuav muab cov nyhuv qib, tom qab ntawd sib tsoo lub hom phiaj los kho qhov kev puas tsuaj tob, tab sis nrog me me.cheeb tsam. Qhov no puas txhais tau tias kev ua haujlwm tau yooj yim? Nyob rau hauv ib qho kev txiav txim, yog, vim hais tias lub ntim ntawm nteg tsis tau muab piv nrog complex tsim ntawm phab ntsa nrog ib tug tshiab txheej. Ntawm qhov tod tes, kev kho dua tshiab ntawm tus kheej ntu ib txwm ua txhaum ntawm qhov chaw geometry - tib qhov kev hem thawj tshwj xeeb yog tshwm sim thaum lub sij hawm sib tsoo ntawm plaster. Nws txhais li cas? Muab ib txheej tuab ntawm mortar rau hauv thaj chaw me me tuaj yeem ua rau muaj teeb meem thaum kho qhov chaw. Yog li ntawd, qhov tseeb ntawm kev siv qhov loj thiab kev sib txuas ntxiv yuav yog qhov tseem ceeb. Qhov teeb meem yog tias kev sib xyaw ua ke yuav tsis muab qhov kev xav tau, txij li cov kua dej sib tov tom qab ua haujlwm tseem deformed nyob rau hauv nws tus kheej load.
Npaj ua haujlwm
Lub luag haujlwm theem thaum lub hom phiaj ua haujlwm tau npaj. Qhov saum npoo yog ntxuav ntawm plua plav, av thiab lwm yam khoom txawv teb chaws. Lub teeb xuab zeb kuj tseem tuaj yeem ua kom tshem tawm cov khaubncaws sab nraud povtseg ntawm qub plaster. Nws tsis tsim nyog overdoing qhov kev ua haujlwm no, vim tias qhov kev hloov pauv muaj zog tuaj yeem cuam tshuam rau cov qauv ntawm cov khoom txheej uas nyob ib sab. Yog hais tias, tom qab stripping, cov ntsiab lus ntawm cov hlau reinforcement tshwm sab nraud, lawv yuav tsum xub muab kaw nrog ib tug tshwj xeeb putty uas yuav siv tau nyob rau hauv kev sib cuag nrog hlau nto. Nws tseem yuav yog ib qho tseem ceeb kom muaj xws li ib tug zoo xws li adhesiveness ntawm kev sib tsoo lub plaster ntawm sab hauv. Qhov no yog ib qho cuab yeej uas txiav txim siab qhov adhesion ntawm cov mortar tshiab rau lub hauv paus nto. Ib yam li tshem tawm cov av los ntawm qhov chaw puas tsuaj txhim kho adhesion, yog li ntawdntawm cov nteg putty yuav tsum, tsawg kawg, organically cuam tshuam nrog kev daws ntawm plaster thov. Txawm li cas los xij, qhov kev xaiv ntawm qhov sib tov tsim nyog yuav tsum tau saib xyuas tshwj xeeb.
Koj xav tau dabtsi?
Cov lus nug tseem ceeb hauv kev xaiv cov khoom sib xyaw qhuav rau kev sib tsoo yog dab tsi yuav tsum yog hom puag? Nws yog qhov zoo dua los tsis kam hloov cov kev sib xyaw tam sim ntawd, txij li cov plasticizers suav nrog hauv cov chaw me me hauv kev sib cuag ncaj qha nrog cov sib txawv txawv teb chaws tuaj yeem pom lawv qhov zoo ntawm ntau txoj kev. Tom qab tag nrho, tsis txhob hnov qab dab tsi sib tsoo ntawm plaster txhais tau tias? Qhov no yog kev koom ua ke ntawm cov kev daws teeb meem tshiab rau hauv cov txheej txheem uas twb muaj lawm. Ib qho kev xaiv thoob ntiaj teb yuav zoo li yog ib qho kev sib xyaw ntawm cov cement, nyob rau hauv uas ob qho tib si adhesion yog siab thiab lub zog yuav ua rau nws muaj peev xwm tsim tau ib qho kev ruaj ntseg foob. Txawm li cas los xij, cov cement-xuab zeb sib tov muaj lub sijhawm kho kom ntev, uas yog qhov tsis zoo rau cov huab hwm coj nyob hauv thaj chaw me me.
Gypsum mortar yuav yog qhov kev daws teeb meem zoo tshaj plaws. Ntxiv nrog rau ib puag ncig tus phooj ywg thiab ceev ceev, xws li lub hauv paus yuav ua rau nws muaj peev xwm ua tau cov yas thiab shrinkage-resistant sib tsoo ntawm plaster. Nws yuav muab dab tsi rau hauv kev xyaum? Ua ntej, nws yuav tshem tawm cov teeb meem ntawm kev puas tsuaj tom qab ua tiav, thaum nws yuav tsim nyog los ua kom tiav thiab kho cov haujlwm. Kev ua tiav yog ua tiav ib zaug, tom qab ntawd cov txheej txheem nteg tsis deformed. Qhov thib ob, gypsum yuav tso cai rau koj los kho txawm tias qhov nyuaj thiab nyuaj mus cuag qhov tseeb vim nws cov yas. Hauv qee qhov xwm txheej, xws li plaster tuaj yeem siv los hloov cov putty.
txheej txheem sib tsoo
Nws yog qhov tsim nyog los ua qhov haujlwm manually nrog lub spatula nrog txoj cai me me rau kev kho qhov chaw. Tom qab 2-3 teev tom qab tso lub hauv paus loj nrog ua tiav sealing ntawm qhov chaw puas, nrog kev pab los ntawm ib tug lattice grater, sags thiab txhua yam irregularities yuav tsum tau muab tshem tawm. Los ntawm txoj kev, phab ntsa plaster sib tsoo yuav ua tau nyob rau hauv ob peb txheej yog hais tias lub embedment qhov tob tshaj 25 cm. Nyob rau hauv cov ntaub ntawv no, thawj txheej yuav tsum tau thov yam tsis muaj kev kho mob nruab nrab. Ntxiv mus, txhawm rau kom adhesion nrog cov txheej tom ntej, thawj qhov chaw yuav tsum tau ua kom ntxhib. Thiab tom qab qhov thib ob dhau, qhov ntau dhau raug tshem tawm thiab kev ntxhib los mos ntawm txheej yog leveled.
Kev sib koom ua ke nrog kev sib koom ua ke
Yog tias koj xav tau ua kom sib sib zog nqus ntawm qhov tawg, nws raug nquahu kom ua qhov kev sib koom ua ntej. Qhov no yog ib hom kev tu, tab sis nyob rau hauv ib tug ntau nyob rau hauv-tob tech version. Txoj kev sib koom ua ke muaj nyob rau hauv kev tshem tawm cov seem ntawm cov teeb meem ua vaj tse raws cov npoo hauv thaj tsam tawg. Cov neeg ua tiav tau qhia kom tshuab tawm cov kab noj hniav tsis zoo nws tus kheej kom ntau li ntau tau, uas yuav txwv tsis pub nws kis mus ntxiv. Nyob rau hauv cov txheej txheem ntawm kev sib tsoo plaster nrog kev sib koom ua ke, lub chisel nrog rauj yog siv los tshem tawm cov qub tiav thiab siv lub tshuab nqus tsev vacuum los ntxuav cov pob txha. Qhov seem ntawm kev ua haujlwm yog ua raws li tus qauv mortar nteg qauv.
Txoj haujlwm sab nraum zoov
Kho ntawm facade txheej muaj nws tus kheej tshwj xeeb,rau qhov kev kho hauv qab no tau ua:
- Cov tshuaj yuav tsum tau ua los ntawm kev sib xyaw ua ke rau kev siv sab nraum zoov. Hauv particular, silicate muab tub lim yuav tso cai rau koj ua qhov zoo sib tsoo ntawm facade plaster. Qhov no txhais li cas ntawm kev ua haujlwm cuam tshuam? Yam tsawg kawg nkaus, kev tiv thaiv los ntawm nag lossis daus yuav muab ntxiv rau cov qauv ntawm thaj chaw muaj teeb meem.
- Tsis txhob siv plaster rau ntawm qhov chaw qias neeg. Txhawm rau ntxuav cov facades, siv lub tshuab ntxhua khaub ncaws tshwj xeeb.
- Sealing yog nqa tawm nrog qhov yuav tsum tau ua ntej primer hauv 2-3 txheej nyias. Nyob rau theem kawg, cov qib ntawm plaster tuaj yeem ua tiav nrog lub sealant waterproof.
Zoo kawg
Raws li kev kho thiab kho dua tshiab, kev sib tsoo tso cai rau koj txuag tag nrho cov qauv ntawm lub hauv paus txheej rau qee lub sijhawm, tab sis koj yuav tsum tsis txhob overestimate nws. Lub heterogeneity ntawm cov qauv tiav nyob rau hauv nws tus kheej tsim cov dej num zoo rau yav tom ntej tsim ntawm cov kab nrib pleb tshiab. Yog li ntawd, cov kws txawj siv lub tswv yim ntawm kev sib tsoo ib ntus ntawm plaster. Nws txhais li cas? Kev kho cov kev puas tsuaj thiab qhov tsis xws luag ntawm cov txheej yog nqa tawm tsuas yog rau qee lub sijhawm kom txog thaum kho dua tshiab. Txwv tsis pub, muaj kev pheej hmoo los txheeb xyuas cov cim ntawm tib cov kab nrib pleb hauv qhov chaw sib tsoo los ntawm kev kho kom zoo nkauj tshiab uas twb muaj lawm hauv thawj lub hlis tom qab ua haujlwm.
