Chii chinonzi thermal conductivity ye insulation?

Thermal conductivity, inozivikanwawo se thermal conductivity, chinhu chakakosha chinotaridza mhedzisiro yezvivakwa.Inoyera kugona kwechinhu kuitisa kupisa uye yakakosha kutarisisa kana uchisarudza zvinhu zvekuvakisa insulation.Kunzwisisa thermal conductivity yekuvharisa kunogona kubatsira varidzi vemba nevavaki kuita sarudzo dzine ruzivo nezvemhando yakanakisa yekuvharisa yekushandisa mudzimba dzavo.

Thermal conductivity chiyero chekugona kwechinhu kuitisa kupisa.Inotaridzwa mumawati pamita padhigirii Celsius (W/mK) uye inoratidza mwero wekufambiswa kwekupisa kuburikidza nechinhu.Zvishandiso zvine yakaderera thermal conductivity zviri nani insulators nekuti vanoitisa kupisa zvishoma.

Kana zvasvika pakupisa kwemafuta, kudziya kwekushisa kunoita basa rakakosha pakuona kugona kwechinhu kuchengetedza chivako chichidziya munguva yechando uye kuchitonhorera muzhizha.Insulation inoshanda nekuteya mahomwe emhepo mukati mechimiro chayo, ichigadzira chipingamupinyi chinononoka kutamisa kupisa.Zvishandiso zvine low thermal conductivity zvinodzivirira kupisa kubva pakubuda kana kupinda muchivako, kuderedza mari yemagetsi uye kunatsiridza kugarika kwemugari.

Thermal conductivity yezvigadzirwa zvekudzivirira zvinogona kusiyana zvichienderana nerudzi rwezvinhu zvinoshandiswa.Semuyenzaniso, fiberglass uye cellulose insulation ine thermal conductivities inosvika 0.04-0.05 W/mK, ukuwo spray foam insulation inogona kunge ine thermal conductivities yakaderera se0.02 W/mK.Nekuda kwekuderera kwavo kwekushisa kwekushisa, zvinhu izvi zvinoonekwa sezvishandiso zvinodzivirira.

Paunosarudza rudzi rwakanaka rwekudzivirira kwechivako, zvakakosha kuti unzwisise kupisa kwekushisa kwekushisa.Zvinhu zvakaita semamiriro ekunze, dhizaini yekuvaka uye zvido zvemunhu zvese zvinotora basa mukuona yakanakisa insulation zvinhu.Paunenge uchisarudza yakanyanya kufanirwa sarudzo yeimwe chivako, zvakakosha kufunga nezve insulation material's R-value uye thermal conductivity.

Mumamiriro ekunze anotonhora, uko mari yekudziya inyaya, zvakakosha kuti usarudze zvinhu zvekudzivirira zvine low thermal conductivity kuti uderedze kurasikirwa kwekupisa.Mumamiriro ekunze anodziya, zvinotariswa zvinogona kunge zviri pakudzivirira kuwanda kwekupisa, saka insulation ine yakaderera thermal conductivity yakakosha zvakaenzana.Nekunzwisisa kudziya kwekushisa kwekudzivirira, varidzi vemba uye vavaki vanogona kusarudza iyo inonyanya kushanda yekuvharisa zvichienderana nezvavanoda chaizvo.

Muchidimbu, iyo thermal conductivity ye insulating material ndicho chinhu chakakosha pakuona kugona kwechinhu ichi kuramba kupisa kuchinjika.Zvishandiso zvine yakaderera thermal conductivity zviri nani insulators, zvinobatsira kuvandudza simba rechivakwa uye kunyaradza.Nekunzwisisa kudziya kwekushisa kwekudzivirira uye kukosha kwayo, varidzi vedzimba nevavaki vanogona kuita sarudzo dzine ruzivo nezvemhando yakanakisa yekuvharisa yekushandisa mudzimba dzavo.
