Cov khoom siv rwb thaiv tsev zoo tshaj plaws yog lub tshuab nqus tsev rwb thaiv tsev (VIP), nrog cov thermal conductivity tsawg li 0.008 W / (m·K), ua rau nws ua tau zoo tshaj plaws rwb thaiv tsev khoom tag nrho.
High-cov ntaub ntawv rwb thaiv tsev ua tau zoo nyob rau hauv cov thermal conductivity: Qhov qis dua thermal conductivity, qhov zoo ntawm rwb thaiv tsev kev ua tau zoo. Cov hauv qab no yog qee cov khoom siv nrog kev ua tau zoo tag nrho:
Vacuum rwb thaiv tsev vaj huam sib luag (VIP): Thermal conductivity kwv yees li 0.008 W / (m·K), tam sim no yog cov khoom siv rwb thaiv tsev uas muaj zog tshaj plaws, feem ntau siv hauv cov tsev tsis muaj zog, siab - cov khoom siv txias txias, thiab lwm yam xwm txheej uas muaj zog heev - txuag cov kev xav tau.
Cov khoom siv Airgel: Thermal conductivity kwv yees li 0.02 W / (m·K), nrog rau qhov zoo xws li ultra-lub teeb, hluav taws kub, thiab dej tsis zoo, haum rau aerospace, muaj siab - cov kav dej kub, thiab lwm yam.
Polyurethane (PUR): Nrog rau cov thermal conductivity ntawm 0.017 ~ 0.024 W / (m·K), nws khav theeb qhov kev ua tau zoo tshaj plaws ntawm cov ntaub ntawv rwb thaiv tsev organic thiab yog siv dav hauv cov phab ntsa sab nrauv, cov chaw cia txias, thiab cov tshuaj tsuag rwb thaiv tsev.
Extruded polystyrene (XPS): Nrog lub thermal conductivity ntawm 0.028 ~ 0.030 W / (m·K), nws kaw -cov qauv ntawm tes muab kev tiv thaiv siab thiab noo noo, ua rau nws haum rau qhov chaw ntub dej xws li hauv qab daus thiab ru tsev.
