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

Tsanangudzo yekupisa kwekushisa: Kazhinji inomiririrwa nemavara “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 kwekupisa kwezvinhu mamiriro, zvinhu zve 1 metres ukobvu, ine tembiricha mutsauko we1 degree pamativi ese, inotamisa kupisa kuburikidza nenzvimbo ye 1 sikweya mita musekondi imwe yezvinyorwa pachayo, uye yakabatana nemhando, nyika (gasi, mvura, yakasimba) uye mamiriro (tembiricha, kumanikidza, humidity, nezvimwewo) zveNhamba, thermal conductivity yakaenzana nekupisa flux density inogadzirwa nekumisikidza kwemukati kwechinhu pasi pekuita kweyuniti gradient. Nezve izvo zvekuisa mukati zvine chekuita nazvo, Iyo yakakwira yekupisa conductivity, iyo yakanyanya kushata basa. Kazhinji kutaura, kupisa kwekupisa kwezvakaoma kwakakura kupfuura kwezvinwiwa, izvo zvakakura kupfuura zvegasi.

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 kuomera kuti mhute yemvura ipinde mukati, saka iyo yekupisa conductivity inokwira zvishoma nezvishoma, uye nguva yakareba inotora kusvika pakutadza kwekudzivirira. , uye kurebesa hupenyu 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.
