1. Kupisa: Kupisa kune simba rakananga pamusoro pekupisa kwekushisa kwezvinhu zvakasiyana-siyana zvekupisa.Sezvo kutonhora kunowedzera, thermal conductivity yezvinhu zvinokwira.

2. Hunyoro hwemukati: Zvose zvinopisa zvinopisa zvinopisa zvine chimiro cheporous uye zviri nyore kutora unyoro.Kana hunyoro hwemukati hwakakura kupfuura 5% ~ 10%, hunyoro hunotora chikamu chepore nzvimbo yakatanga yakazadzwa nemhepo mushure mekunge zvinhu zvatora hunyoro, zvichiita kuti hunoshanda hwekupisa huwedzere zvakanyanya.

3. Kuwanda kwehuwandu: Kuwanda kwehuwandu chiratidzo chakananga cheporosity yezvinhu.Sezvo thermal conductivity yegasi gasi kazhinji iri shoma pane iyo yechikamu chakasimba, thermal insulation zvinhu zvine porosity yakakura, kureva, diki diki density.Mumamiriro ezvinhu akajairwa, kuwedzera ma pores kana kuderedza kuwanda kwehuwandu kuchaita kuti kuderera kwekupisa kwekushisa.

4. Particle saizi yezvinhu zvakasununguka: Patembiricha yekamuri, iyo yekupisa conductivity yezvinhu zvakasununguka inoderera sezvo saizi yechinhu ichiderera.Kana iyo particle size yakakura, ukuru hwepakati pakati pezvimedu hunowedzera, uye kupisa kwekupisa kwemhepo iri pakati kuchawedzera.Iyo diki saizi yechikamu, idiki iyo tembiricha coefficient ye thermal conductivity.

5. Heat flow direction: Ukama huri pakati pekupisa kwekushisa uye kutungamira kwekupisa kunongowanikwa mune anisotropic zvinhu, kureva, zvinhu zvine maitiro akasiyana-siyana mumativi akasiyana-siyana.Kana iyo yekupisa inotungamira inotenderera kune iyo fiber kutungamira, iyo yekupisa insulation performance iri nani pane iyo yekutamisa kupisa inofananidzwa nefiber direction;zvakafanana, iyo thermal insulation performance yechinhu chine nhamba huru yevhavha yakavharwa zvakare iri nani pane iyo ine yakakura yakavhurika pores.Zvishandiso zvestomatal zvinopatsanurwazve kuita mhando mbiri: chinhu chakasimba chine mabhubhu uye zvimedu zvakasimba mukusangana kudiki.Kubva pakuona kwekurongeka kwezvinhu zvefibrous, pane zviitiko zviviri: kutungamira uye kuyerera kwekupisa kwakanangana neperpendicular uye iyo fiber kutungamira uye kupisa kuyerera kunofanana.Kazhinji, iyo fiber kurongeka kwefiber insulation material ndeyekupedzisira kana padyo neiyo yekupedzisira.Iyo yakafanana density mamiriro ndeimwe, uye yayo kupisa conduction Iyo coefficient yakanyanya kudiki pane thermal conductivity yemamwe marudzi e porous insulation zvinhu.

6. Mhedzisiro yekuzadza gasi: Muchigadzirwa chekudzivirira kupisa, kunyanya kupisa kunoitwa kubva kune gasi mumapores.Nokudaro, iyo inopisa conductivity ye insulating material inonyanya kugadziriswa nemhando yekuzadza gasi.Muinjiniya yekudzikira-tembiricha, kana helium kana hydrogen izere, inogona kutorwa seyekutanga-yekurongeka yekufungidzira.Inofungidzirwa kuti kupisa kwekushisa kwezvinhu zvinodzivirira zvakaenzana nemafuta ekupisa kwemagasi aya, nokuti kupisa kwekushisa kwehelium kana hydrogen kwakakura.

7. Kunyanya kupisa simba: Iyo chaiyo yekupisa huwandu hweiyo insulating zvinhu inoenderana nekutonhora kwesimba (kana kupisa) kunodiwa kutonhora nekudziya kweiyo insulating chimiro.Pakudziya kwakadzika, iyo chaiyo yekupisa kugona kwezvinhu zvese zvakaonda inosiyana zvakanyanya.Pasi peyakajairika tembiricha uye kumanikidzwa, mhando yemhepo haipfuure 5% yezvinhu zvekudzivirira, asi sezvo tembiricha inodonha, chikamu chegasi chiri kuwedzera.Naizvozvo, chinhu ichi chinofanirwa kutariswa kana uchiverenga thermal insulation zvinhu zvinoshanda pasi pekumanikidzwa kwakajairwa.

8. Coefficient yekuwedzera kwemutsara: Paunenge uchiverenga kusimba uye kugadzikana kwechimiro chekudzivirira mukati mekugadzirisa kutonhora (kana kupisa), zvakakosha kuziva coefficient yekuwedzera kwemutsara wezvinyorwa zvekudzivirira.Kana iyo mutsara wekuwedzera coefficient ye thermal insulation material idiki, iyo thermal insulation chimiro hachinyanyi kukuvadzwa nekuda kwekuwedzera kwekupisa uye kuputika panguva yekushandiswa.Iyo coefficient yemutsara wekuwedzera weakawanda emafuta ekudzivirira zvinhu anodzikira zvakanyanya sezvo tembiricha inodzikira.
