Cov kav dej ntawm ntau lub tshuab, raws li txoj cai, muaj qhov ntev. Lawv qhov chaw yog ob qho tib si rau saum npoo av thiab hauv av. Yog li ntawd, nws yog ib qho tseem ceeb heev uas qhov kev ua tau zoo ntawm kev sib cais ntawm kev sib txuas lus los ntawm qhov txias thiab lwm yam kev cuam tshuam sab nraud yog txaus siab. Cov yeeb nkab rwb thaiv tsev ua haujlwm zoo heev.
Lub hom phiaj ntawm thermal rwb thaiv tsev
Qhov teeb meem loj tshaj plaws thiab muaj ntau tshaj plaws yog qhov khov ntawm cov kav dej nyob rau sab nraum zoov ntawm cov kav dej thiab hauv qhov chaw tsis muaj cua sov. Nws yog qhov ntse dua los siv cov txheej txheem rwb thaiv tsev thawj zaug dua li tshem tawm qhov tshwm sim tom qab.
thermal rwb thaiv tsev ntawm cov kav dej tiv thaiv kev sib txuas lus los ntawm xeb uas tshwm sim ntawm cov hlau ntawm qhov system vim yog qhov tsim ntawm condensate tas li. Raws li qhov tshwm sim, cov kav dej ua thinner thiab ua tsis tiav.
rwb thaiv tsev rau cov kav dej pab kom tsis txhob poob cua sov. Los ntawm kev tswj xyuas qhov kub thiab txias hauv cov kav dej ntawm cov cua sov, tus tswv yuav tuaj yeem txo cov nqi hluav taws xob ntau.
Yuav tsum tau rau cov yeeb nkab rwb thaiv tsev
- Tsawg thermal conductivity, tso caitxo qhov kub poob.
- siab zog thiab ua haujlwm ntev.
- Dav kub ntau yam. Kev hloov pauv kub yuav tsum tsis txhob cuam tshuam rau cov khoom ntawm cov rwb thaiv tsev, tshwj xeeb tshaj yog thaum nws los txog rau cov kav dej kub uas nyob ntawm txoj kev.
- Txhim khu kev ruaj ntseg waterproofing uas yuav tsis cia dej los yog condensate los ntawm rwb thaiv tsev.
- Cov yeeb nkab zoo rwb thaiv tsev tsis raug cuam tshuam rau ib puag ncig tsis zoo.
- Kev nyab xeeb hluav taws. Thaum insulating piping systems nyob rau hauv qhov chaw uas muaj hluav taws kub (chaw da dej, chav chav, thiab lwm yam), tsuas yog siv cov khoom uas tsis yog-combustible.
- Yooj yim rau nruab. Hauv kev tsim kho lossis kev rwb thaiv tus kheej, qhov no yog qhov tseeb ntxiv.
Ntau yam cua sov
- Mineral wool lossis bas alt rwb thaiv tsev. Nws yog cov khoom siv muaj zog nrog lub neej ua haujlwm ntev. Qhov kub ntawm kev siv yog dav heev - los ntawm -60 ° C mus rau + 200 ° C. Flexibility thiab adhesion yog qhov zoo. Cov paj rwb ntaub yog ntxiv dag zog nrog fiberglass los yog ntawv ci.
- iav ntaub plaub muaj qhov coefficient ntawm thermal conductivity - los ntawm 0.028 txog 0.034 W / m. Nws tsis yog-combustible thiab tsis raug rau qhov kub thiab txias. Nws tsuas muaj ib qho tsis zoo - siab hygroscopicity, yog li xav tau ib txheej ntxiv ntawm cov khoom siv insulating rau sab nraud. Raws li lub tshuab cua sov rau cov kav dej cua sov, nws tau siv ntau zaus, ua ib qho ntawm cov khoom pheej yig - los ntawm 60 mus rau 80 rubles ib 1 kg.
- Rwb thaiv tsev ua npuas ncauj polystyrene, qhov tseeb, tib lub npuas dej, tab sis nyob rau hauv daim ntawv tshwj xeeb. Nws muaj txiaj ntsig zoo hauv kev siv ntawm qhov kub ntawm -80 ° C txog + 180 ° C. Nws cov thermal conductivity yog siab dua li ntawm cov ntaub ntawv dhau los - txog 0.05 W / m. Txawm li cas los xij, nws tseem khaws cov cua sov zoo. Nws cov txiaj ntsig muaj xws li kev yooj yim ntawm kev teeb tsa - cov ntsiab lus tau tsim nyob rau hauv daim ntawv ntawm hemispheres, uas nws yooj yim heev los qhwv cov yeeb nkab seem thiab fasten lub halves. Cov txheej txheej ntawm rwb thaiv tsev muaj txheej txheej sab nraud, uas ua rau nws hnav tsis kam. Tus nqi yog nyob ntawm txoj kab uas hla thiab thickness ntawm cov khoom. Qhov thinnest rwb thaiv tsev nqi txog 60 rubles. ib 'meter'.
- rwb thaiv tsev rau cov kav dej "plhaub" yog ua los ntawm polyurethane ua npuas ncauj thiab zoo ib yam hauv nws cov khoom ua npuas ncauj. Nws muaj ob halves, zoo li lub plhaub walnut, uas yog superimposed ntawm cov yeeb nkab los ntawm ob sab thiab khov kho nrog hlau. Muaj qhov ntaug ntom thiab kwv yees tib coefficient ntawm thermal conductivity, cov khoom siv yooj yim ua kom muaj kev kub ntxhov ntawm -180 ° C rau +130 ° C. Thaum dismantled, nws khaws tag nrho nws cov thermal rwb thaiv tsev, yog li nws tuaj yeem rov qab siv dua. Yuav kav txog 30 xyoo. Tus nqi ntawm rwb thaiv tsev txawv ntawm 200 txog 1000 rubles, nyob ntawm seb qhov loj ntawm cov khoom.
pheej yig thiab yooj yim rwb thaiv tsev - polyethylene ua npuas ncauj. Ua tsaug rau cov qauv zoo-mesh, nws zoo kawg nkaus khaws cov cua sov. Nws thermal conductivity tsis siab tshaj 0.05 W / m. Kev khiav hauj lwm kub yog los ntawm -50 ° C mus + 90 ° C. Nws muaj qhov hnyav me me thiab tuab, uas txhais tau tias nws txuag chaw. Durable, yuav kav ntau tshaj 100 xyoo. Tus nqi nyob ntawm qhov tuab ntawm daim ntawv thiab yog kwv yees li 160-200 rubles ib kab meter
Ib qho ntawm cov khoom siv thermal rwb thaiv tsev niaj hnub tshaj plaws yog cov kua dej rwb thaiv tsev. Nws muaj qhov qis tshaj thermal conductivity - 0.01 W / m, diluted nrog dej thiab yooj yim rau kev thov. Thaum qhuav, nws ntseeg tau los tiv thaiv cov dej noo, txuag cua sov zoo. Tus nqi yog 350-400 rubles ib liter
Installation
Nws tag nrho nyob ntawm seb hom rwb thaiv tsev yog coj li cas. Cov iav ntaub plaub feem ntau siv rau cov kav dej cua sov, thiab cov txheej txheem siv nws yog qhov yooj yim heev. Cov txheej yog qhov txhab ntawm cov yeeb nkab thiab fastened nrog nplaum daim kab xev nyob ib ncig ntawm tag nrho cov perimeter. Qhov no ua kom muaj kev ncaj ncees txawm tias cov yeeb nkab yog deformed los ntawm kev hloov hauv av.
Nqe
Qhov ntau ntawm cov nqi rau cov yeeb nkab rwb thaiv tsev yog qhov loj heev, txhua yam nyob ntawm cov khoom siv thiab cov chaw tsim khoom. Qhov pheej yig tshaj yog polyethylene ua npuas ncauj. Qhov kim tshaj plaws yuav raug nqi polyurethane plhaub thiab kua rwb thaiv tsev. Kev ntseeg siab thiab kev ua haujlwm tsis zoo ntawm ntau yam kev sib txuas lus engineering feem ntau txiav txim siab qhov muaj nyob zoo. Nws yog ib txwm muaj peev xwm xaiv cov yeeb nkab rwb thaiv tsev, tus nqi ntawm tus nqi pheej yig, thiab cov yam ntxwv ntawm kev ua haujlwm tau lees tias kev lag luam thiab ceev faj ntawm cov kav dej thiab cua sov.
