Ƙididdigar aikin haɓakar thermal na kayan aikin haɓakar thermal an ƙaddara ta hanyar haɓakar thermal na kayan.Karami na thermal conductivity, mafi kyawun aikin rufin thermal.Gabaɗaya, kayan da ke da ƙarancin zafin jiki na ƙasa da 0.23W / (m · K) ana kiran su kayan daɗaɗɗen zafi, kuma kayan da ke da ƙarancin zafin jiki ƙasa da 0.14W / (m · K) ana kiran su kayan aikin thermal;yawanci ma'aunin zafin jiki bai fi 0.05W/(m ·K) kayan ana kiransu kayan aikin insulation masu inganci ba.Abubuwan da ake amfani da su don rufin gini gabaɗaya suna buƙatar ƙarancin ƙima, ƙarancin zafin jiki, ƙarancin sha ruwa, kwanciyar hankali mai kyau, ingantaccen aikin rufi, ingantaccen gini, abokantaka na muhalli, da farashi mai ma'ana.

Abubuwan da ke tasiri tasirin thermal conductivity na thermal insulation kayan.

1. Yanayin kayan.Thermal conductivity na karafa shi ne mafi girma, sai kuma wadanda ba karafa.Ruwan ya fi karami kuma iskar gas ya fi karami.

2. Bayyanar yawa da halayen pore.Abubuwan da ke da ƙarancin ƙarancin ƙarancin ƙima suna da ƙarancin ƙarancin zafi.Lokacin da porosity ya kasance iri ɗaya, girman girman pore, mafi girma ƙarfin wutar lantarki.

3. Danshi.Bayan abu ya sha danshi, yanayin zafi zai karu.Thermal conductivity na ruwa ne 0.5W/(m·K), wanda shi ne 20 sau girma fiye da thermal conductivity na iska, wanda shine 0.029W/(m·K).Ƙarƙashin zafin jiki na ƙanƙara shine 2.33W / (m · K), wanda ke haifar da mafi girma na thermal conductivity na kayan.

4. Zazzabi.Yawan zafin jiki yana ƙaruwa, ƙaddamarwar thermal na kayan yana ƙaruwa, amma zafin jiki ba shi da mahimmanci lokacin da zafin jiki ya kasance tsakanin 0-50 ℃.Sai kawai don kayan a yanayin zafi mai girma da mara kyau, ya kamata a yi la'akari da tasirin zafin jiki.

5. Matsayin zafin zafi.Lokacin da zafin zafi ya kasance daidai da jagorancin fiber, aikin haɓakar thermal yana raunana;lokacin da zafin zafi ya kasance daidai da jagorancin fiber, aikin haɓakar thermal na kayan haɓakar thermal shine mafi kyau.
