Iyo thermal insulation performance index ye thermal insulation material inotarwa neiyo thermal conductivity yezvinhu.Iyo diki iyo thermal conductivity, zviri nani iyo thermal insulation performance.Kazhinji, zvinhu zvine thermal conductivity zvisingasviki 0.23W/(m·K) zvinodaidzwa kunzi heat insulation materials, uye zvinhu zvine thermal conductivity zvisingasviki 0.14W/(m·K) zvinodaidzwa kuti thermal insulation materials;kazhinji iyo thermal conductivity haina kukura kupfuura 0.05W/(m ·K) zvinhu zvinodaidzwa kuti high-efficiency insulation materials.Zvishandiso zvinoshandiswa pakuvaka insulation zvinowanzoda yakaderera density, yakaderera yekupisa conductivity, kunyura kwemvura yakaderera, yakanaka dimensional kugadzikana, yakavimbika insulation kuita, kuvaka kuri nyore, hushamwari kwezvakatipoteredza, uye mutengo unonzwisisika.

Zvinhu zvinokanganisa thermal conductivity ye thermal insulation materials.

1. Mamiriro ezvinhu.Thermal conductivity yesimbi ndiyo yakakura, inoteverwa neasina simbi.Mvura yacho idiki uye gasi idiki.

2. Inooneka density uye pore maitiro.Zvishandiso zvine density yakaderera ine low thermal conductivity.Kana iyo porosity yakafanana, iyo yakakura iyo pore saizi, iyo huru yekupisa conductivity.

3. Humidity.Mushure mokunge zvinhu zvinotora unyoro, kupisa kwekushisa kuchawedzera.Thermal conductivity yemvura ndeye 0.5W/(m·K), iyo yakakura zvakapetwa makumi maviri pane thermal conductivity yemhepo, iyo 0.029W/(m·K).Thermal conductivity yechando ndeye 2.33W/(m·K), izvo zvinoguma nekuwedzera kwekupisa kwekupisa kwezvinhu.

4. Tembiricha.Iyo tembiricha inowedzera, kupisa kwekushisa kwezvinhu kunowedzera, asi tembiricha haina kukosha kana tembiricha iri pakati pe0-50 ℃.Chete kune zvigadzirwa pane yakakwirira uye yakaipa tembiricha, mhedzisiro yekushisa inofanirwa kutariswa.

5. Heat flow direction.Kana kupisa kunoyerera kuchienderana nefiber direction, iyo thermal insulation performance inoderera;kana kuyerera kwekushisa kuri perpendicular kune iyo fiber kutungamira, iyo yekupisa yekupisa mashandiro eiyo thermal insulation material ndiyo yakanyanya kunaka.
