Cov yeeb nkab ua npuas dej yog corrosion-resistant, muaj kev ua haujlwm zoo thermal rwb thaiv tsev thiab muaj lub neej ua haujlwm ntev. Piv nrog rau lwm cov ntaub ntawv rwb thaiv tsev yeeb nkab, cov nyhuv rwb thaiv tsev ntawm cov yeeb nkab rwb thaiv tsev yog nce los ntawm 4-9 zaug. Cia peb tham txog cov yam ntxwv thiab kev tsim kho ntawm cov yeeb nkab ua npuas ncauj:
Tus nqi nqus dej ntawm cov yeeb nkab ua npuas dej yog qhov tsawg heev, kwv yees li 0.2 kg/square meter. Yog vim li cas rau qhov tsis tshua muaj dej nqus ntawm cov yeeb nkab rwb thaiv tsev yog qhov kaw ntawm tes ntawm polyurethane ua npuas ncauj yog siab li 92 feem pua. Tsawg thermal conductivity, tsis tshua muaj dej nqus, siab ntom polyethylene los yog fiberglass kho plhaub, zoo rwb thaiv tsev, waterproof sab nrauv. Polyurethane txhav ua npuas ncauj rwb thaiv tsev txheej ntawm lub npuas rwb thaiv tsev yeeb nkab yog sib txuas nrog txheej txheej ntawm cov yeeb nkab steel, uas tuaj yeem tiv thaiv huab cua thiab dej nkag mus rau txheej txheej ntawm cov yeeb nkab steel, kom ua tiav cov nyhuv ntawm kev tiv thaiv corrosion.
Lub luag haujlwm tseem ceeb ntawm cov yeeb nkab rwb thaiv tsev yog txhawm rau txo qhov poob ntawm cov cua sov nruab nrab thaum lub sijhawm thauj mus los, txuag roj, tswj cov cua sov kom zoo, thiab ua tau raws li cov neeg siv khoom xav tau. Kev siv cov prefabricated ncaj qha faus thermal rwb thaiv tsev paj rwb cov kav dej tuaj yeem txo qhov ntev ntawm cov kav dej cua sov thiab cov khoom siv, yog li txo cov nqi engineering. Tsis tas li ntawd, cov yeeb nkab rwb thaiv tsev ua npuas dej kuj tuaj yeem txo cov cua kub ntawm cov yeeb nkab rwb thaiv tsev mus rau ib puag ncig, vim tias cov yeeb nkab rwb thaiv tsev yog insulated. Daim ntawv thov ntawm cov yeeb nkab rwb thaiv tsev kuj tseem tuaj yeem tiv thaiv qhov kub ntawm cov yeeb nkab los ntawm kev siab dhau thiab scalding tu cov neeg ua haujlwm.
Txhawm rau tiv thaiv kev xeb ntawm cov yeeb nkab ua npuas dej, qhov chaw ntawm cov yeeb nkab yuav tsum tau coated nrog cov khoom siv los tiv thaiv xeb ua ntej. Lub thickness ntawm cov rwb thaiv tsev txheej yog txiav txim los ntawm kev sib piv ntawm kev lag luam thiab kev lag luam. Cov txheej tiv thaiv feem ntau yog coated nrog asbestos cement los yog asphalt iav ntaub thiab ib lub casing hlau. Yog tias tsim nyog, kev ntsuas dej tsis zoo yuav tsum tau coj mus rau sab nraud ntawm txheej tiv thaiv. Cov txheej txheej txheej tiv thaiv yuav tsum zoo huv si, du, zoo nkauj, thiab nyob rau hauv kev sib raug zoo nrog ib puag ncig ib puag ncig, thiab qee zaum yuav tsum tau siv cov txheej xim xim rau cov yeeb nkab sib txawv.
Thaum lub sij hawm tsim cov yeeb nkab ua npuas ncauj, qhov zawj yuav tsum tiaj tus kom cov hauv qab ntawm qhov zawj qhuav. Nws yuav tsum muaj cov xuab zeb zoo li 200 hli, thiab tsawg kawg yog ob sab thiab sab sauv ntawm cov yeeb nkab rwb thaiv tsev yuav tsum tau them nrog cov xuab zeb zoo li 200 hli. Nws lub hom phiaj yog los tiv thaiv cov khoom tawv los ntawm kev puas tsuaj rau lub tsho insulating, thiab siv cov fluidity ntawm cov xuab zeb kom txaus los ua kom tiav qhov khoob ntawm cov kav dej kom muaj kev sib txhuam txaus.
Tom qab kev teeb tsa lub raj xa dej ntawm cov yeeb nkab ua npuas dej ua tiav, kev ntsuas dej siab ntawm 1.5 npaug ntawm kev ua haujlwm siab yuav tsum tau ua, thiab kev kho lub ntsej muag foaming tuaj yeem nqa tawm tsuas yog tom qab ntsuas dej siab tau tsim nyog. Nws yuav tsum tau ua kom paub tseeb tias sab nrauv ntawm cov yeeb nkab steel yeeb nkab, qhov kawg ntawm qhov kawg ntawm ob sab thiab sab nrauv ntawm lub plhaub ntawm lub puab tsaig yog tshem tawm tag nrho ntawm cov dej, roj, impurities thiab qhov kawg ntawm cov txheej txheem tiv thaiv. Thaum lub interface txais polyurethane ua npuas ncauj, lub ambient kub yuav tsum tsis txhob qis dua 10 degree.
