Ndehupi hukama pakati peiyo thermal conductivity uye wet rendi chinhu cheiyo insulation material?

Tsanangudzo yekupisa kwekushisa: Inowanzomiririrwa nechimiro che "λ", uye chikwata ndeichi: Watt/meter·degree (W/(m·K), apo K inogona kutsiviwa ne ℃. Thermal conductivity (inozivikanwawo sekuti thermal conductivity kana thermal conductivity) chiyero chekupisa kwekushisa kwechinhu. Inofananidzira mamiriro ekugadzirisa kupisa pasi pemamiriro ekupisa kwekushisa pasi pekushisa kwekushisa. Mamiriro, chinhu che 1 metres ukobvu, ine tembiricha ye1 degree pamativi ese, inotamisa kupisa kuburikidza nenzvimbo ye 1 square mita musekondi 1 inoratidza kuti kupisa kwemafuta ndeimwe yezvakasikwa uye kemikari zvimiro zvechigadzirwa chacho, uye ine hukama nerudzi, nyika (gasi, mvura, yakasimba) uye mamiriro (tembiricha, kumanikidza, hunyoro hwehunyoro, hunyoro). flux density inogadzirwa nekumisikidza kwemukati kwechinhu pasi pechiito cheunit gradient.

Iyo wet rendi factor µ parameter inoratidza kugona kwechinhu kuramba kupinda kwemhute yemvura uye haina dimensionless huwandu. Iyo unit is m, zvinoreva kuti yakaenzana nemhute yemvura permeability yemhepo yem. Inotsanangura maitiro ezvinyorwa, kwete kuita kwechigadzirwa kana chimiro.

Nezvemidziyo yekudzivirira ine imwechete yekutanga thermal conductivity K asi yakasiyana µ, iyo yakakwirira iyo µ kukosha, zvakanyanya kuoma kuti mhute yemvura ipinde muzvinhu, saka iyo yekupisa conductivity inokwira zvishoma nezvishoma, uye iyo yakareba inotora kusvika pakutadza kwekudzivirira, uye kureba kwehupenyu hwesevhisi.
Kana iyo µ kukosha kwakadzikira, thermal conductivity inosvika pakutadza kukosha munguva pfupi nekuda kwekukurumidza kupinda kwemhute yemvura. Naizvozvo, chete kukora dhizaini ukobvu hunogona kuwana humwe hupenyu hwesevhisi seyakakwira µ kukosha kwezvinhu.
Zvigadzirwa zveJinfulai zvinoshandisa yakakwira mvura yekurenda zvinhu kuti ive nechokwadi chekudzikama kwekupisa, saka kutetepa kwekutanga ukobvu kunogona kuve nechokwadi chehupenyu hwesevhisi.

Zvigadzirwa zveKingflex zvinoshandisa yakakwira mvura yekurenda zvinhu kuti ive nechokwadi chakagadzikana chekushisa conductivity, saka kutetepa kwekutanga ukobvu kunogona kuve nechokwadi chehupenyu hwesevhisi.
Kana iwe uine chero mumwe mubvunzo wehunyanzvi, ndapota inzwa wakasununguka kubata neKingflex timu.
