Ib lub raj xa dej nyob sab nraud ntawm qhov chaw yuav tsum tau rwb thaiv tsev. Qhov tshwj xeeb yog txoj kev loj uas tau muab tso rau hauv qab qhov tob tob. Thermal rwb thaiv tsev kuj yuav tsum tau rau ib tug yeeb nkab nyob rau hauv ib tug unheated chav tsev. Rwb thaiv tsev tso cai rau koj los ua kom muaj kev ua haujlwm ntawm cov kab sib txuas lus thiab txuas ntxiv lawv lub neej kev pabcuam. Kev siv cov rwb thaiv tsev zoo rau cov kav dej tso cai rau koj tuaj yeem tiv thaiv lawv los ntawm kev khov, txo cov cua sov los ntawm cov cua sov thiab tshem tawm qhov tsim ntawm condensate.
Vim li cas cov yeeb nkab rwb thaiv tsev tsim nyog?
Kev ua kom zoo thermal rwb thaiv tsev tso cai:
- Txo qhov tsis tsim nyog thiab tsis npaj ua kom sov hauv cov kav dej cua sov.
- Txo qhov muaj peev xwm ntawm condensation ntawm cov kav dej thiab hauv cov insulator.
- Muab qhov ntsuas kub rau saum lub rwb thaiv tsev.
- Txhawb kev pabcuam lub neej ntawm cov kav dej los ntawm kev ua kom qeeb ntawm cov xeb.
- Tiv thaiv polypropylene thiab hlau-yas kav thiab cov kav dej los ntawm kev puas tsuaj.
- rwb thaiv tsev rau cov kav dej cua sov sab nraum zoov khaws cov cua sov thiab tiv thaiv kom tsis txhob khov rau lub caij ntuj no.
Yuav xaiv cov khoom zoo li cas?
Raws li txoj cai, kev xaiv yog raws li cov hauv qab no:
- pipe diameter;
- tshav kub rwb thaiv tsev nqi;
- nyob rau hauv cov xwm txheej yuav ua haujlwm li cas;
- pipeline length;
- kev ua tau zoo.
Yuav ua li cas rwb thaiv tsev rau cov kav dej?
Kev xaiv cov khoom siv rau cov rwb thaiv tsev thermal nyob ntawm, raws li txoj cai, ntawm lub hom phiaj ntawm txoj kab, txoj kab uas hla ntawm cov yeeb nkab thiab kev ua haujlwm. Cov khoom siv rwb thaiv tsev yuav tsum muaj:
- nce cua sov txuag;
- qis thermal conductivity;
- nplaim hluav taws;
- tawm tsam rau lwm qhov tsis zoo;
- yooj yim ntawm kev teeb tsa - rau cov neeg uas xav ua rwb thaiv tsev ntawm lawv tus kheej, qhov no yog qhov tseem ceeb;
- dej resistant;
- durability.
Txhawm rau kom muaj cua sov hauv tsev, nws yog ib qho tsim nyog tsis yog tsuas yog yuav cov kav dej thiab lwm yam khoom, tab sis kuj yuav tsum saib xyuas kom ntseeg tau tias lawv ua haujlwm. Yog li, txhawm rau txhawm rau kev sib txuas lus kom tsis txhob ua kom tsis txhob khov nyob rau hauv qhov cuam tshuam ntawm qhov kub thiab txias, nws yog ib qho tsim nyog yuav tsum tau yuav cov rwb thaiv tsev zoo rau cov kav dej kub ua ntej. Niaj hnub no, ntau yam ntawm cov ntaub ntawv rau thermal rwb thaiv tsev yog loj, tab sis ua ntej txiav txim siab zaum kawg, koj yuav tsum paub koj tus kheej nrog lawvyam ntxwv zoo.
Feem ntau, thermal rwb thaiv tsev rau cov yeeb nkab yog ua los ntawm cov ntaub ntawv hauv qab no:
- YPolyethylene ua npuas ncauj (polyethylene ua npuas ncauj).
- YPolyurethane ua npuas ncauj.
- Mineral wool.
Cov rwb thaiv tsev thermal nyob rau hauv daim ntawv ntawm bas alt thooj voos kheej kheej kuj muaj.
YPolyethylene ua npuas ncauj (polyethylene ua npuas ncauj)
Tam sim no, nrog rau cov cuab yeej cua sov, thermal rwb thaiv tsev rau cov yeeb nkab ua los ntawm polyethylene ua npuas ncauj yog siv dav heev. Hais txog qhov zoo / nqi - qhov no yog qhov kev xaiv zoo tshaj plaws. Foamed polyethylene thermal rwb thaiv tsev yog tsim nyob rau hauv 2 lub ntsiab hom:
- ob-meter raj;
- canvas.
Khoom yuav coated nrog polyethylene, aluminium ntawv ci, thiab lwm yam.
PE ua npuas ncauj thermal rwb thaiv tsev rau cov kav dej muaj cov yam ntxwv hauv qab no:
- Thermal conductivity coefficient (ntawm 40 ° C) - 0.043 W / mK.
- Chav diffusion kuj coefficient - > 3000.
- Kub ntau (ua haujlwm): -80 txog +95 deg.
- Pab pawg combustibility - cov khoom siv hluav taws xob qeeb (G1 thiab G2).
- Scope ntawm daim ntawv thov - cua sov, qhov cua thiab cov kav dej phwj tuaj.
- Kev xa khoom - hauv lub raj.
Cov yeeb nkab rwb thaiv tsev no muaj qhov ntev hauv qab no: phab ntsa thickness yog los ntawm 6mm mus rau 30mm, txoj kab uas hla yog 6mm txog 160mm.
Tus nqi ntau heev. Tus nqi ntawm cov yeeb nkab rwb thaiv tsevSuav ntau lawm yog 5-7 npaug tsawg dua European, txawm li cas los xij, qhov zoo yog qhov qis dua.
Qhov no ua npuas ncauj rwb thaiv tsev yog yooj yim rau nruab. Koj tsuas yog yuav tsum tau txiav tawm qhov tsim nyog strip, qhwv thiab ruaj ntseg nrog daim kab xev.
Raws li nws cov yam ntxwv ua tau zoo, thermal rwb thaiv tsev rau cov yeeb nkab ua los ntawm hluavtaws foamed roj hmab yog qhov zoo tshaj rau txhua hom. Tab sis nws cov nqi siab dua. Yog li ntawd, cov yeeb nkab rwb thaiv tsev no feem ntau yog siv rau hauv cov txheej txheem engineering tseem ceeb tshaj plaws uas yuav tsum tau ua haujlwm rau qhov kub thiab txias, ultraviolet hluav taws xob, hluav taws kub, thiab lwm yam.
Cov yam ntxwv tseem ceeb ntawm cov khoom siv no:
- Thermal conductivity coefficient ntawm 40 deg. yog 0.038 W/mK.
- Kub ntau (ua haujlwm): -80 txog +95 deg.
- combustibility pab pawg ntawm cov khoom - Г1.
- Scope ntawm daim ntawv thov - cua txias thiab tub yees tshuab.
- Muab cov raj, txoj kab uas hla 6-160mm, cov khoom siv phab ntsa thickness 6-32mm.
- Khoom siv yog UV tiv taus.
Kua (txhaj tshuaj thiab xim) insulators
Cov no yog cov ntaub ntawv tshiab hauv kev tsim kho. Muaj ob lub ntsiab ntawm cov kua insulators:
- Sprayed. Lawv raug siv rau saum npoo los ntawm kev txau, siv cov cuab yeej tshwj xeeb (piv txwv li, PPU).
- Painting. Lawv raug siv rau saum npoo zoo li cov xim tsis tu ncua nrog cov menyuam lossis txhuam.
Ob txoj kev xaiv muaj qhov zoo dua: cov insulators tuaj yeem siv tau qhov kev siv yob hom rwb thaiv tsev tsis yooj yim los yog nyuaj.
YPolyurethane ua npuas ncauj
Polyurethane ua npuas ncauj semi-cylinders (PPU plhaub) yog cov rwb thaiv tsev tsis zoo tsim los rau cov yeeb nkab rwb thaiv tsev. Nws yog ua tau los npog nrog ntau hom waterproofing - glassine, ntawv ci, ntawv ci glassine FPGK, polyethylene zaj duab xis, thiab lwm yam. Ib qho ntawm qhov zoo ntawm cov rwb thaiv tsev no yog qhov yooj yim ntawm installation. Rau ib hnub ua haujlwm, ib pab 2 tus neeg yuav tau them 300 m.p. thiab ntau dua.
Khoom specifications:
- Thermal conductivity yog - 0.035 W / mK.
- Kub ntau (ua haujlwm): -150 txog +120 deg.
- combustibility pab pawg ntawm cov khoom - Г3.
- Scope ntawm polyurethane ua npuas ncauj - cua sov thiab dej kub.
- Deliveries- ib nrab lub tog raj kheej.
- Loj rau txoj kab uas hla 32-1020mm yog: phab ntsa thickness - 40mm (los yog customized), ntev - 1-1.5m.
Penoizol
Cov khoom siv no muaj cov yam ntxwv siab thermal. Nws yog siv, raws li txoj cai, ntawm kev lag luam nplai, txij li kev siv tshuaj tsuag tshwj xeeb yuav tsum tau siv rau hauv cov yeeb nkab.
Penoizol yog cov kua dej sib xyaw ua ke siv los ntawm kev txau. Thaum cov khoom solidifies, ib qho airtight sheath yog tsim nyob ib ncig ntawm cov yeeb nkab, uas xyaum tsis kis cua sov.
Yuav tsum hais tias cov khoom zoo li no tsis tuaj yeem hu ua pheej yig.
Mineral thiab fiberglass wool
Nov yog cov khoom pheej yig tshaj plaws uas tsim tawm hauv cov yob thiab daim hlau.
Nws yog qhov zoo tshaj plaws los siv cov yob hom rwb thaiv tsev. Cov khoom siv yog ib qho yooj yim rau nruab (koj yuav tsum qhwv cov yeeb nkab hauv ob peb txheej thiab khi cov qauv nrog cov hlua khi), nrog rau kev siv cov kav dej sib txawv.
thermal rwb thaiv tsev rau cov kav dej hauv qhov qhib cua nrog nws cov kev pab yog nqa tawm los ntawm winding thiab txuas ntxiv txuas nrog hluavtaws twine lossis stainless hlau.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov khoom siv no yuav tsum tau them nrog cov txheej txheem dej tsis zoo. Ntawm txoj kev, qhov no yuav cawm nws kom tsis txhob ntub thiab poob khoom, thiab sab hauv tsev, nws yuav cawm nws ntawm qhov muaj cov khoom siv microparticles hauv huab cua.
Kev ua haujlwm thermal ntawm cov khoom siv no zoo heev.
tshav kub rwb thaiv tsev rau cov kav dej cua sov hauv chav tsev
Nws mus yam tsis tau hais tias tsis tas yuav zais cov roj teeb hauv chav. Cov ntu ntawm cov cua sov network nyob rau hauv cov chav uas muaj qhov kub thiab txias yog tswj kom tsis txhob muaj rwb thaiv tsev.
Rwb thaiv tsev yuav tsum tau siv rau hauv cov cheeb tsam ntawm cov cua sov uas tau muab tso rau hauv cov chav uas tsis muaj qhov kub thiab txias (piv txwv li, hauv qab daus).
Cov rwb thaiv tsev kub rau cov kav dej cua sov sab nraum zoov thiab hauv chav tsev yog sawv cev ntawm cov khoom siv hauv tsev ua lag luam los ntawm cov tuam txhab hauv tebchaws thiab Europe thiab Lavxias.
Xaiv dab tsi los thaiv cov kav dej cua sov, muaj ntau. Feem ntauxav txog kev ua haujlwm thermal, tom qab ntawd yooj yim ntawm kev teeb tsa.
Tsuas kawg, xyuam xim rau tus nqi rwb thaiv tsev, vim qhov no yog qhov nws yuav ua tau los ntsuas qhov ua tau zoo ntawm txhua ruble nqis peev hauv rwb thaiv tsev. Cov khoom pheej yig tab sis cov khoom siv tsis zoo yuav dhau los ua tsis tsim nyog thiab ua haujlwm me me, thiab hloov pauv qhov kev cia siab, nws tsuas yog ua rau kev poob siab thiab teeb meem cuam tshuam.
