Sealing seams yog ib qho ntawm cov txheej txheem thev naus laus zis tseem ceeb hauv kev tsim cov vaj huam sib luag. Sij hawm dhau mus, interpanel seams thiab pob qij txha pib tawg, ua rau pwm, xau thiab fungus, uas ua rau khov ntawm phab ntsa.
Qhov laj thawj tseem ceeb ntawm kev puas tsuaj ntawm interpanel pob qij txha
Cov laj thawj hauv qab no rau kev sib koom ua ke kev nyuaj siab tuaj yeem txheeb xyuas:
- tsis ua raws li cov qauv kev siv tshuab thaum lub sijhawm tsim kho;
- maj mam hloov ntawm phab ntsa panels vim tsis sib haum ntawm cov khoom thauj khoom ntawm cov qauv;
- deformation ntawm panels vim kub hloov pauv;
- cuam tshuam rau cov pob qij txha ntawm cov huab cua xws li "acid nag lossis daus", daus thiab nag.
cov ntaub ntawv kaw lus
Rau sealing thiab rwb thaiv tsev ntawm interpanel pob qij txha, tshwj xeeb sealing mastics thiab tus kheej-nplaum daim kab xev yog siv. Cov sealants no tuaj nyob rau hauv ntau hom, cov khoom xyaw thiab daim ntawv thov.
Cov khoom tseem ceeb uas tsim nyog rau kev sib khi cov pob qij txha yog lub sealant, uas yuav ua tau lub tshav kub tiv thaiv kev ua haujlwm, thiab tseem yog lub hauv paus rau cov ntaub nplaum nplaum thiab nws tus kheej nplaum nplaum.
Cov sealants zoo tshaj plaws yog cov khoom sib xyaw raws li foaming polyurethane (PPU). Vim yog cov xwm txheej no, kev puas tsuaj thiab deformation ntawm interpanel pob qij txha tshwm sim, uas ua rau kom ceev ceev ntawm cov phab ntsa sab nrauv nyob rau lub caij ntuj no, nrog rau lawv cov dej xau thaum los nag hnyav. Raws li qhov tshwm sim ntawm qhov no, tsis tsuas yog lub tsev sab hauv tuaj yeem ua rau tsis zoo, tab sis kev pheej hmoo ntawm kev mob ntawm cov neeg muaj peev xwm kuj tuaj yeem nce ntxiv.
hom kev sib koom ua ke
- Primary sealing yog siv rau hauv kev tsim kho tshiab uas tsis tau siv cov sealant.
- Secondary sealing muaj xws li kho cov pob qij txha ntawm lub tsev uas tab tom ua haujlwm tam sim no.
Primary sealing
hom kev sib khi no feem ntau yog ua hauv vaj huam sib luag tom qab lawv tsim kho.
Interpanel seams ntawm cov tsev tshiab tau ua tiav hauv 3 theem:
- Cov kab noj hniav tsis muaj kab noj hniav yog ntim nrog cov khoom siv hluav taws xob tiv thaiv polyurethane ua npuas ncauj.
- Cov seam interpanel tau kho nrog Vilaterm rwb thaiv tsev tshiab, uas yog ib qho zoo-mesh, cov khoom siv dawb dawb.
- Tsis tas li ntawd, cov seam tau kaw los ntawm sab nraud nrog cov mastic tshwj xeeb,nrog dej zoo.
Kev siv peb theem no tso cai rau koj los tsim ib lub npe hu ua "sov seam", uas tso cai rau koj muab kev ruaj ntseg thermal thiab waterproofing nyob rau hauv tag nrho cov huab cua puag.
Secondary sealing
Ua hauv cov tsev uas qee lub sijhawm dhau los cov kev sib txuas sib txuas tau raug rau cov txheej txheem kho mob no. Nws yog qhov zoo tshaj plaws los ua qhov kev sib khi thib ob 6-8 xyoo tom qab thawj lub rwb thaiv tsev. Interpanel seams, uas tau rov ua dua, raug kaw los ntawm kev npog cov txheej qub ntawm sealant nrog ib qho tshiab.
Interpanel seams. Sealing: cov cai dav dav
Raws li lub xeev ntawm cov seam, qhov kev sib khi thib ob tau muab faib ua ob hom.
Yog tias nws nyob hauv qhov kev txaus siab, yog tias cov rwb thaiv tsev qub tsis tau raug puas tsuaj loj, kev ua haujlwm thib ob tsuas yog txwv rau kev siv cov txheej txheem tshiab ntawm cov dej tsis zoo. Yog tias tag nrho cov cim ntawm kev puas tsuaj loj ntawm cov seams interpanel pom meej, ces qee qhov kev ua haujlwm yuav tsum tau ua thaum lawv rov ua dua. Cov no suav nrog: qhib lub seam, tshem tawm tag nrho cov khoom qub qub uas tau dhau los ua tsis tau, thiab ua tiav tag nrho cov kev sib khi ua haujlwm, xws li hauv qhov kev sib khi tseem ceeb.
Thaum ua haujlwm kho vaj huam sib luag, koj yuav tsum ua raws qee cov cai:
- Nyob rau hauv rooj plaub ntawm kev sib koom ua ke ntawm lub vaj huam sib luag hauv phab ntsa kawg, lub interpanel seams ntawm tag nrho cov phab ntsa kawg raug kawlub façade ntawm lub tsev, nrog rau cov pob qij txha ntawm qhov kawg panels thiab cov phab ntsa longitudinal.
- Yog tias qhov sib txuas ntsug ntawm qhov ntev ntawm lub façade xau, tag nrho cov kab txuas ntsug raws tag nrho qhov siab ntawm lub tsev raug kaw. Tsis tas li ntawd, tag nrho cov kab rov tav cov pob qij txha uas nyob ib sab ntawm nws raug kaw.
- Yog tias pom muaj qhov tsis xws luag hauv kab rov tav, tag nrho cov pob qij txha nyob rau ntawm peb lossis plaub kab ntsug ntawm cov vaj huam sib luag yuav raug muab khi.
- Thaum ua cov haujlwm kho vaj huam sib luag ntawm cov pob qij txha, ib tus yuav tsum tau coj mus rau hauv tus account qhov tseeb tias cov sealants raug nruj thiab compression ntawm cov pob qij txha. Qhov no yog cuam tshuam los ntawm qhov kub thiab txias, shrinkage thiab "creep" ntawm cov pob zeb, nrog rau cov loads tshwm sim los ntawm kev sib haum xeeb ntawm tag nrho lub tsev. Ntxiv mus, nrog rau qhov nce ntawm qhov sib piv ntawm cov thickness ntawm tus neeg sawv cev hermetic txheej rau qhov dav ntawm interpanel seam, xws li loads zog. Vim li no, txheej sealant yuav tsum yog ib nrab ntawm qhov dav ntawm qhov sib koom ua ke.
Sealing ntawm interpanel seams. Technology
Interpanel seams, lub sealing ntawm uas yuav tsum tau zoo tshaj plaws, yog ua tiav nyob rau hauv ob peb theem. Rau qhov ruaj khov tshaj plaws ntawm cov pob qij txha txuas ntxiv, nws yog qhov tsim nyog los qhib lawv.
Peb thov kom txiav txim siab ib ntus kho vaj huam sib luag nrog qhib.
Cov kev sib khi hauv qab ntawm pob qij txha hauv cov tsev prefabricated yog hu ua "sov sib koom ua ke". Nws lub ntsiab sib txawv yog daim ntawv thov ntawm ib txheej ntawm tshwj xeeb tshav kub-shielding ua npuas ncauj rau lub hauv paus ntawm seams.
Qhov kev ua tiav noKev kho seam tau raug sim ntau thiab tau siv ntau lub teb chaws thoob ntiaj teb tau ntev.
Kev sib khi ua ke hauv tsev
Cia peb xav txog yuav ua li cas insulate interpanel seams.
1. Nyob rau thawj theem ntawm kev ua haujlwm, ua ntej kho cov pob qij txha, nws yog ib qho tsim nyog yuav tau ua qee qhov kev npaj ua ntej. Lawv muaj nyob rau hauv kev tshuaj xyuas zoo ntawm interpanel seams thiab kev npaj nto. Qhov no suav nrog:
- ntxuav qhov chaw los ntawm cov xim, plua plav, av thiab cov vaj huam sib luag xoob;
- tshem tawm ntawm cov seams thiab pob qij txha ntawm cov qub, hnav-tawm rwb thaiv tsev thiab sealant;
- Kev sib koom ua ke.
2. Interpanel seams tau ua tib zoo ntim nrog cov cua sov-insulating polyurethane ua npuas ncauj (mounting ua npuas ncauj). Nws yuav tsum tau muab sau tseg tias cov khoom no nyiam nthuav thaum lub sij hawm solidification thiab yog li sau cov void uas twb muaj lawm nyob rau hauv lub seam. Kev ntxuav thiab sib khi ntawm cov seams hauv cov tsev tuaj yeem ua tau ob qho tib si manually thiab mechanically. Ua ntej pib ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas qhov chaw ntawm cov pob qij txha interpanel. Nws yuav tsum qhuav.
3. Rwb thaiv tsev ntawm interpanel seams los ntawm kev txhim kho Vilaterm rwb thaiv tsev, uas muaj nyob rau hauv daim ntawv ntawm hollow hlab. Nws yog dav siv hauv kev kho cov seams hauv vaj huam sib luag vaj huam sib luag. Raws li nws cov khoom, cov khoom muaj elasticity zoo, ntom qauv, nws yooj yim heev rau lawv ua hauj lwm. Pw "Vilaterm" rau ntawm ib txheej ntawm npaus uas tseem tsis tau hardened. Hauv txoj kab uas hla, nws yuav tsum yog 25-30%ntau tshaj qhov dav seam.
Insulation yog pw yam tsis muaj kev tawg raws tag nrho ntev kom muaj chaw rau kev siv cov sealant rau saum cov rwb thaiv tsev.
4. Cov theem kawg yog sealing cov seams nrog sealing mastic (dej-repellent sealant), uas kaw cov rwb thaiv tsev yav dhau los.
Qhov no ua kom tiav kev sib khi ntawm cov pob qij txha interpanel!
Seaming nruab nrab ntawm cov vaj huam sib luag ntawm lub tsev yog ua nyob rau hauv qhov kub ntawm -10 ° C txog +30 ° C. Hauv qhov no, yuav tsum tsis txhob muaj nag lossis daus, txwv tsis pub kev sib khi ntawm cov pob qij txha yuav luv luv.
Vaj huam sib luag uas tau kaw saum toj 2 hauv pem teb yog kaw los ntawm cov neeg ua haujlwm tsim nyog.
