Gas-filled plastics, uas sab nraud sawv cev rau cov khoom siv los ntawm cov hlwb ua npuas ncauj, tau muab cais ua npuas dej. Raws li kev tsim cov thev naus laus zis thiab cov khoom siv polymer, cov chav kawm no suav nrog ntau hom khoom siv uas muaj kev siv sib txawv. Tag nrho cov ntawm lawv muaj thermal rwb thaiv tsev cov khoom thiab tsis muaj tshuaj lom. Qhov nrov PSB-S-25 facade rwb thaiv tsev ua npuas ncauj ua tau raws li kev huv thiab huv thiab yog lub hauv paus rau txhua yam ntawm plaster.
cov ntaub ntawv dav dav
Nrog rau kev nce nqi ntawm cov khoom siv hluav taws xob, qhov teeb meem tiag tiag yog kev tiv thaiv cov txheej txheem ntawm lub tsev los ntawm kev tsis txhob tso cua sov rau sab nraud. Qhov tsawg ntom ntawm cov npuas dej muab cov khoom siv nrog kev ua haujlwm siab thermal rwb thaiv tsev. Yog li ntawd, rwb thaiv tsev ntawm facades nrog npuas yas yog ib qho kev daws teeb meem niaj hnub rau kev txuag hluav taws xob. Txawm hais tias qhov no nyob deb ntawm thaj tsam nkaus xwb ntawm kev thov rau cov khoom siv no.
Kuj siv:
- ua ib qho muab tso rau hauv qhov chaw ntawm cov nkoj, uas ua kom lawv cov dej tsis huv;
- hauv kev tsim cov tsho cawm neeg txoj sia, buoys thiab ntab;
- ua cov khoom siv rau kev tsim cov thawv kho mob uas siv los thauj cov khoom pub dawb;
- yog kev tiv thaiv rau cov khoom tawg yooj yim;
- ua lub tshav kub hauv lub tub yees thiab lwm yam khoom siv hauv tsev.
hom rwb thaiv tsev
Muaj cov txheeb cais, uas tsis tau lees paub los ntawm cov ntaub ntawv tswj hwm, qhov kub poob ntawm phab ntsa yog 40%, los ntawm lub ru tsev - 25%. Yog li ntawd, nws muaj peev xwm ua tau kom muaj kev tiv thaiv siab tshaj plaws ntawm vaj tse los ntawm kev poob cua sov los ntawm insulating cov phab ntsa.
Muaj ob txoj hauv kev los cais ib chav los ntawm kev nkag mus ntawm cov dej noo thiab cov cua txias tam sim no: los ntawm sab hauv thiab sab nraud. Nws ntseeg tau tias nws muaj peev xwm tiv thaiv phab ntsa los ntawm kev khov thiab tib lub sijhawm khaws cia thaj chaw sab hauv ntawm lub tsev thaum xaiv cov rwb thaiv tsev sab nraud. Thiab lwm qhov zoo dua ntawm kev tiv thaiv façade ntawm lub tsev yog qhov tseeb tias thaj chaw condensation tsim ntawm cov rwb thaiv tsev sab hauv thiab cov phab ntsa load-cov kabmob. Thiab qhov no yog ib qho chaw zoo tagnrho rau kev loj hlob ntawm fungus thiab pwm. Tab sis ib phab ntsa tiv thaiv sab nraud khaws cua sov ntev dua thiab tsis txias.
Txawm hais tias muaj xwm txheej, piv txwv li, nyob rau hauv rooj plaub ntawm kev ua tiav zoo nkauj ntawm lub tsev lossis lub elevator ncej, thaum nws yog technically tsis yooj yim sua kom insulate nrog npuas yas los ntawm sab nraud. Tom qab ntawd siv cov kev tiv thaiv sab hauv ntawm phab ntsa. Ntxiv nrog rau ua npuas dej, cov neeg tsim khoom siv lwm cov ntaub ntawv.
Tim cov ntaub ntawv
Cov cua kub nrov: cov ntaub plaub ntxhia, polyurethane ua npuas ncauj thiab nthuav polystyrene. Mineral wool yog mounted tsuas yog nyob rau ntawm ib tug hlau ncej, uas yuav tsum tau sheathed nrog plasterboard los xij, siding los yog lwm yam khoom tiav. Polyurethane ua npuas ncauj muaj qhov zoo ib ntus, txij li nws tau thov cia, siv lub tshuab txau. Nyob rau hauv cov ntaub ntawv no, cov ntaub ntawv sau tag nrho cov kab nrib pleb nyob rau hauv lub thav duab, tsim ib tug monolithic txheej. Txawm li cas los xij, kev tiv thaiv cov phab ntsa hauv txoj kev no yuav raug nqi ntau dua li kev siv npuas rau rwb thaiv tsev.
Polystyrene ua npuas ncauj yog tsim nyob rau hauv ob txoj kev, ua rau cov khoom uas tsis yog nias thiab extruded. Marking PS-1 txhais tau hais tias cov npuas dej yog pobzeb xovxwm tsim, thiab PSB-S yog cov khoom siv uas muaj peev xwm tua tus kheej. Ntawd yog, polystyrene nrog txo cov nplaim taws tau siv hauv nws qhov chaw tsim khoom.
yam ntxwv zoo
Rwb thaiv tsev ntawm facades nrog ua npuas ncauj pib nrog kev xaiv ntawm cov khoom. Cov yam ntxwv tseem ceeb uas koj yuav tsum paub thaum yuav khoom rwb thaiv tsev yog qhov ntev ntawm daim hlau, ntom thiab thickness. Raws li GOST 15588-86, qhov nominal qhov ntev ntawm daim hlau tuaj yeem yog:
- thickness hauv 10mm increments: 20-500mm;
- raws qhov ntev hauv qhov nce ntawm 50 mm: 900-5000 mm;
- hauv dav hauv increments ntawm 50 mm: 500-1300 mm.
Tab sis nws tau tso cai, los ntawm kev pom zoo ua ntej, los tsim cov phiaj xwm ntawm qhov ntau thiab tsawg. Foam boards yog tsim los nrog cov nqi ceev hauv qab no: 15, 25, 35 thiab 50 kg / m3. Qhov ntsuas no siab dua, cov khoom siv muaj zog dua thiab qis dua nws lub peev xwm nqus dej noo. Daim ntawv nrog qhov ceev ntawm 35 kg / m3 thickness 50mm yog zoo ib yam nyob rau hauv nws lub cev thiab tshuaj zog rau cov khoom uas muaj ib tug ceev ntawm 25 kg/m3 thiab ib tug tuab ntawm 100 hli. Txawm li cas los xij, tus nqi ntawm polystyrene yog siab dua, qhov ceev ntawm cov rwb thaiv tsev ntau dua.
Xaiv lub rhaub ntawm ib lub thickness, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus account ntau yam thiab ua kom yooj yim xam.
Xaiv lub thickness ntawm cov khoom zoo
Lub thickness ntawm cov rwb thaiv tsev thermal nyob ntawm tus nqi ntawm cov qauv kev hloov hluav taws xob ntawm cov phab ntsa sab nrauv, uas yog tus nqi tas li rau cov cheeb tsam huab cua sib txawv, thiab cov thickness ntawm cov khoom ntawm cov phab ntsa ntawm lub tsev.
Piv txwv li, qhov tsawg kawg nkaus tso cai thermal kuj ntawm phab ntsa rau St. Petersburg yog 3.08m2R/W. Muaj ib lub tsev cib, cov phab ntsa uas ua los ntawm ib-thiab-ib-ib-ib nrab ceramic hollow cib. Lub thermal tsis kam ntawm qhov tsim no yog 1.06m 2 xK / W. Nws yog ib qho tsim nyog los xam qhov tuab npaum li cas thiaj li ua npuas dej rau rwb thaiv tsev.
Txhawm rau ua tiav tus nqi ntawm 3.08, nws yog qhov yuav tsum tau nrhiav qhov sib txawv ntawm cov qauv thiab cov thermal uas twb muaj lawm: 3.08-1.06=2.02 m 2 xK / W. Ntawd yog, tus nqi uas ua npuas ncauj yuav tsum tau paub. Rwb thaiv tsev PSB-25 ntawm qhov zoo tshaj plaws muaj cov thermal conductivity (raws li GOST) 0.039 W / (m K)
Raws li cov qauv uas cov thermal tsis kam yog qhov sib piv ntawm cov txheej tuab rau cov coefficient ntawm thermal conductivity ntawm cov khoom, peb muaj: 2.020.039=0.078 m. Qhov no, PSB-25 ua npuas ncauj 80 mm tuab yuav tsum tau yuav. Qhov kev suav no tsis suav nrog cov thermal tsis kam ntawm plaster txheej, uasmuaj nyob rau hauv thiab sab nraum lub tsev. Yog li ntawd, qhov tseeb, qhov yuav tsum tau ua npuas ncauj thickness yuav tsawg dua 80 hli.
Dab tsi ntxiv tuaj yeem ua npuas dej?
Vim qhov dej nqus coefficient tsawg, cov khoom siv feem ntau siv rau hauv qhov chaw muaj av noo siab. Cov nplooj ntawv Styrofoam tau muab tso rau hauv cov qauv hauv paus, siv hauv kev tsim cov tsev hauv qab daus-dawb.
Txhawm rau tiv thaiv kom tsis txhob khov ntawm lub hauv paus ntawm lub tsev, nws raug nquahu kom nteg cellular rwb thaiv tsev hauv nws cov kab rov tav thiab ntsug. Raws li lub suab rwb thaiv tsev, ua npuas dej tuaj yeem tso rau hauv ib lub phab ntsa cuav ntawm chav. Kev nthuav dav polystyrene kuj tseem siv los thaiv cov plag tsev, balconies, loggias. Ntxiv rau kev tiv thaiv cov qauv los ntawm kev poob cua sov, cov khoom siv yog siv hauv cov tub yees.
Styrofoam nqi
Nqe lus no qhia txog tus nqi ntawm cov chav kawm ua npuas ncauj thaum lub Kaum Ib Hlis 2015 tus nqi.
nthuav polystyrene, ua los ntawm extrusion, hu ua penoplex. Cov phaj zoo li no muaj zog dua li polystyrene, thiab lawv cov nqi ntau dua. Tus nqi ntawm ib phaj (1200x600x50 mm) yog 183 rubles, nyob rau hauv cov nqe lus ntawm 1 m 3 qhov no yog 5080 rubles.
Ntawm cov chaw muag khoom cua sov, xws li cov khoom npe xws li 50 hli polystyrene feem ntau pom. Qhov no yog cov ntaub ntawv zoo tib yam nrog qhov ntev ntawm 1000x2000 mm. Tus nqi ntawm ib phaj yog 180 rubles. Tam sim no, nyob rau hauv kev sib piv nrog foam yas, nws yog tseeb hais tias ib lub voos xwmfab ntawm zoo tib yam ua npuas ncauj yas 50 hli tuab nqi 1800 rubles, thiab qhov no yog 3200 rubles pheej yig dua extrusion. Styrofoam.
Yog li, ib lub voos xwmfab ntawm cov npuas dej zoo tib yam, nyob ntawm qhov ceev, tus nqi:
- PSB-S15 - 2160 rubles;
- PSB-S25 - 2850 rubles;
- PSB-S35 - 4479 rubles;
- PSB-S50 - 6699 rubles.
Myths that Styrofoam for insulation is harm
thawj zaj dab neeg muaj feem cuam tshuam nrog lo lus coined "phab ntsa ua pa". Muaj kev xav tias thaum insulating vaj tse nrog npuas yas, qhov nkag ntawm cov pa vapor txo qis, yog li ua rau lub microclimate tsis zoo, thiab cov av noo siab hauv chav. Tsis muaj lo lus "ua pa phab ntsa" hauv kev tsim kho, thiab cov dej ntws ntawm cov vapor uas ua tau ncig ntawm txoj kev thiab lub tsev los ntawm phab ntsa yog me me heev. Kev tsim cov pwm thiab cov kab mob hauv chav tom qab cov phab ntsa yog insulated nrog npuas yas yog qhov tshwm sim ntawm qhov cua tsis zoo.
Qhov thib ob lus dab neeg yog kev phooj ywg ib puag ncig ntawm cov khoom. Expanded polystyrene hais txog cov khoom uas tsis muaj tshuaj lom neeg ntxiv. Nws yog 98% huab cua thiab 2% polystyrene. Nws yog non-radioactive thiab tuaj yeem 100% rov ua dua. Ua haujlwm kub: -200… + 80 ℃. Tab sis nthuav dav polystyrene raug rau acetone, benzene, yog li qhov tseeb no yuav tsum tau coj mus rau hauv tus account thaum xaiv cov xim rau qhov kawg ntawm lub façade.
