Thermal rwb thaiv tsev xav tau ntawm polyurethane rwb thaiv tsev yeeb nkab
Raws li ob txoj kev xaiv tseem ceeb hauv thaj chaw ntawm kev rwb thaiv tsev, cov kav dej polyurethane thiab roj hmab- cov kav dej yas muaj qhov sib txawv ntawm cov ntaub ntawv, kev ua tau zoo, thiab cov xwm txheej siv tau, thiab lawv cov ntsuas hluav taws xob tshwj xeeb kuj tseem muaj qhov sib txawv. Polyurethane rwb thaiv tsev yeeb nkab siv nruj polyurethane ua npuas ncauj raws li lub rwb thaiv tsev txheej thiab yog them nrog ib tug siab - ntom polyethylene tiv thaiv txheej. Nws muaj lub zog muaj zog thiab kev ua haujlwm siab zoo (Ntau dua lossis sib npaug rau 0.3MPa). Nws tuaj yeem tiv taus qhov kub nruab nrab ntawm -196℃rau 120 degree, thiab nrog qhov kub thiab txias li 0.
Nrog rau cov thermal conductivity qis dua 033W / (m·K), nws muaj cov thermal rwb thaiv tsev thiab lub zog-txuag cov teebmeem. Factory prefabricated ntau lawm ua kom ruaj khov zoo thiab tsim lub neej ntev txog 30 xyoo. Nws yog tshwj xeeb tshaj yog haum rau loj -scale ncaj qha faus tej yaam num xws li centralized cua sov, txias, thiab crude roj tsheb thauj mus los. Hauv qhov sib piv, roj hmab- cov kav dej yas yog ua los ntawm nitrile roj hmab ua npuas ncauj. Lawv yog cov mos hauv kev ntxhib los mos, yooj yim rau kev tsim, thiab muaj cov khoom tiv thaiv zoo tshaj -condensation. Txawm li cas los xij, lawv muaj lub zog qis, yooj yim rau hnub nyoog, thiab muaj lub neej tsuas yog 5 txog 10 xyoo. Lawv tsim nyog rau huab cua{14}}cov kav dej txias thiab cov kav dej hauv tsev hauv tsev thiab muaj nqi qis dua. Raws li qhov tseem ceeb ntawm kev rwb thaiv tsev ntawm cov kav dej polyurethane muaj kev txhawj xeeb, GB / T yuav tsum nruj me ntsis raws li 29047-2021 tus qauv, cov npuas ntom ntom yuav tsum tsis pub tsawg dua 60kg / m³, kaw cov xov tooj ntawm tes yuav tsum ntau dua 88%, thiab cov dej nqus dej yuav tsum tau tswj xyuas nyob rau hauv lub sijhawm ntev {2% burial 10% ib puag ncig; Nyob rau tib lub sijhawm, cov cua sov ua haujlwm yuav tsum ua tau raws li 120℃kev ua haujlwm, thiab lub zog axial shear yuav tsum tsis pub tsawg tshaj 0.12MPa ntawm chav tsev kub kom ntseeg tau tias muaj kev sib raug zoo ntawm cov txheej txheem rwb thaiv tsev thiab cov yeeb nkab phab ntsa. Tag nrho hauv tag nrho, kev xaiv ntawm cov khoom siv yuav tsum yog raws li qhov project tiag tiag: yog tias qhov kev tsom mus rau ntev - lub sij hawm txuag hluav taws xob thiab kev ntseeg tau ntawm cov qauv, cov kav dej polyurethane yog qhov kev xaiv zoo tshaj plaws; yog tias qhov kev tsom mus rau luv luv -lub sij hawm kev lag luam thiab kev tiv thaiv kev tiv thaiv sab hauv tsev, cov roj hmab thiab cov yas rwb thaiv tsev cov kav dej muaj txiaj ntsig zoo dua.
