Polyurethane rwb thaiv tsev kav thiab pob zeb wool rwb thaiv tsev kav yog ob hom ntaub ntawv siv nyob rau hauv pipeline rwb thaiv tsev tej yaam num. Lawv cov ntaub ntawv thiab kev ua tau zoo sib txawv, thiab qhov kev xaiv nyob ntawm qhov nruab nrab qhov kub thiab txias, txoj kev tso, thiab ntev - cov nqi khiav lag luam.
Polyurethane rwb thaiv tsev kav yog tam sim no cov khoom siv dav siv hauv cov kav dej hauv cheeb tsam cua sov. Rigid polyurethane ua npuas ncauj muaj cov thermal conductivity ntawm 0.022 txog 0.028 W / (m·K), tso nws cov rwb thaiv tsev ntawm cov khoom siv zoo tshaj plaws. Raws li tus qauv GB/T 29047, qhov ntev -lub sij hawm ua hauj lwm kub yuav tsum tsis txhob ntau tshaj 120 degree, thiab lub sij hawm ncov kub yuav tsum tsis txhob ntau tshaj 130 degree. Nws muaj qhov kaw- xovtooj ntawm ntau dua 90%, kev nqus dej tsawg, thiab kev ua haujlwm tsis zoo, ua rau nws tsim nyog rau kev faus ncaj qha yam tsis tas yuav muaj txheej txheej dej ntxiv ntxiv. Cov yeeb nkab tiv thaiv sab nrauv siv siab - ntom polyethylene, uas tuaj yeem tiv taus av siab thiab av yaig. Yog li ntawd, polyurethane rwb thaiv tsev kav yog lub ntsiab kev xaiv rau faus pipeline rwb thaiv tsev nyob rau hauv lub cheeb tsam cua sov, txias, thiab petrochemical industries.
Pob zeb wool rwb thaiv tsev kav yog tsim los ntawm tej yam ntuj tso minerals xws li basalt, ua tiav los ntawm siab - kub melting thiab fiberization. Nws cov thermal conductivity yog kwv yees li 0.035 txog 0.045 W / (m·K), me ntsis siab dua polyurethane, tab sis nws qhov zoo yog nyob rau hauv siab - kub tsis kam thiab hluav taws kub. Qhov siab tshaj plaws kev khiav hauj lwm kub tuaj yeem ncav cuag 650 degree, thiab nws qhov kev ua tau zoo ntawm kev sib txuas mus txog Qib A (tsis yog-} combustible), ua rau nws tsim nyog rau rwb thaiv tsev ntawm cov khoom siv kub xws li cov kav dej, boilers, boilers, thiab flues. Txawm li cas los xij, pob zeb wool muaj cov dej tsis muaj zog; nws cov rwb thaiv tsev kev ua tau zoo txo qis tom qab nqus dej, xav tau kev kho dej ntxiv hauv qhov chaw ntub dej. Tsis tas li ntawd, polyurethane ncaj qha - cov kav dej faus muaj lub neej ua haujlwm thermal ntawm ntau xyoo caum, thaum cov kav dej pob zeb yuav tsum tau hloov txhua 10 mus rau 15 xyoo, uas ua rau muaj kev ua haujlwm siab dua thiab cov nqi kho mob. Pob zeb wool kav yog feem ntau nteg overhead los yog nyob rau hauv trenches, yuav tsum tau tseem ceeb thawj zaug civil engineering peev thiab tsis tu ncua nqi hloov.
Nyob rau hauv luv luv, polyurethane insulated kav yog tsim rau cua sov thiab cua txias pipelines nrog kub tsis tshaj 120 degree, tshwj xeeb tshaj yog rau centralized cua sov tej yaam num nrog ncaj qha faus; pob zeb wool insulated kav yog tsim rau siab - cov kav dej kub nrog qhov kub siab tshaj 120℃, xws li cov kav dej thiab cov khoom siv kub siab -, tab sis yuav tsum tau them nyiaj rau kev tiv thaiv kev ya raws thiab hloov tsis tu ncua. Qhov kev xaiv nyob ntawm qhov ntsuas kub nruab nrab, tom qab ntawd nyob ntawm qhov chaw tso thiab ntev - cov nqi khiav lag luam.
