Inkomba yokusebenza kwe-thermal insulation ye-thermal insulation material inqunywa ukuqhutshwa kokushisa kwezinto.Okuncane kwe-thermal conductivity, kungcono ukusebenza kwe-thermal insulation.Ngokuvamile, izinto ezine-thermal conductivity ezingaphansi kuka-0.23W/(m·K) zibizwa nge-thermal insulation materials, futhi izinto ezine-thermal conductivity ezingaphansi kuka-0.14W/(m·K) zibizwa nge-thermal insulation materials;ngokuvamile i-thermal conductivity ayikho ngaphezu kuka-0.05W/(m ·K) izinto ezibizwa ngokuthi izinto zokuvikela ezisebenza kahle kakhulu.Izinto ezisetshenziselwa ukuvikela amabhilidi ngokuvamile zidinga ukuminyana okuphansi, ukuguquguquka kwe-thermal okuphansi, ukumuncwa kwamanzi okuphansi, ukuqina okuhle kwe-dimensional, ukusebenza okuthembekile kokufakwa ngaphakathi, ukwakhiwa okulungile, ubungane bemvelo, kanye nezindleko ezizwakalayo.

Izici ezithinta conductivity ezishisayo of thermal insulation materials.

1. Ubunjalo bempahla.I-thermal conductivity yezinsimbi yiyona enkulu kunazo zonke, ilandelwa yi-non-metals.Uketshezi luncane futhi igesi incane kakhulu.

2. Ukuminyana okubonakalayo kanye nezici zembotshana.Izinto ezinobukhulu obuncane obubonakalayo zine-conductivity ephansi ye-thermal.Uma i-porosity ifana, ubukhulu be-pore bukhulu, i-conductivity enkulu yokushisa.

3. Umswakama.Ngemuva kokuthi izinto zithatha umswakama, ukuqhutshwa kwe-thermal kuzokwanda.I-thermal conductivity yamanzi ngu-0.5W/(m·K), okuyinkulu ngokuphindwe izikhathi ezingu-20 kunomoya oshisayo, ongu-0.029W/(m·K).I-thermal conductivity yeqhwa ngu-2.33W/(m·K), okuholela ekuphatheni okukhudlwana kwe-thermal kwento.

4. Izinga lokushisa.Izinga lokushisa liyakhula, ukuqhutshwa kokushisa kwezinto kuyakhuphuka, kodwa izinga lokushisa alibaluleki lapho izinga lokushisa liphakathi kuka-0-50 ℃.Kuphela ngezinto zokwakha emazingeni okushisa aphezulu kanye namabi, umphumela wokushisa kufanele ucatshangelwe.

5. Isiqondiso sokugeleza kokushisa.Lapho ukugeleza kokushisa kuhambisana nesiqondiso se-fiber, ukusebenza kokushisa okushisayo kuba buthaka;lapho ukugeleza kokushisa ku-perpendicular kusiqondiso se-fiber, ukusebenza kwe-thermal insulation ye-thermal insulation material kungcono kakhulu.
