Ipeyinti yepolymer epholisa izakhiwo

Iinjineli ziphuhlise ukusebenza okuphezulu kwangaphandle kwe-PDRC (ukuphola kwemitha yasemini yokupholisa) ukutyabeka iipolymer kunye nezikhewu zomoya ezisusela kwiinanometer ukuya kwiminiscels ezinokusetyenziswa njengomoya opholileyo ozenzekelayo ophahleni, izakhiwo, iitanki zamanzi, izithuthi nkqu nesiphekepheke - nantoni na enako Basebenzise indlela yokuguqula isigaba-isisombululo ukunika ipolymer ifomathi enjenge-foam.Xa ibonakaliswe esibhakabhakeni, isambatho sePolymer sePDRC sibonisa ukukhanya kwelanga kunye nokufudumeza ukufezekisa amaqondo obushushu asezantsi kunezinto zokwakha eziqhelekileyo. umoya.

Ngokunyuka kwamaqondo obushushu kunye namaza obushushu aphazamisa ubomi kwihlabathi liphela, isisombululo sokupholisa siya sisiba yinto ebaluleke ngakumbi Lo ngumcimbi ophambili, ngakumbi kumazwe asaphuhlayo, apho ubushushu behlobo bunokuba bukhulu kwaye kulindeleke ukuba buqine Kodwa iindlela eziqhelekileyo zokupholisa, ezinjengomoya Ukulungisa imeko, kuyabiza, kusebenzisa amandla amaninzi, kufuna ukufikelela okulungeleyo kumbane, kwaye kuhlala kufuna i-ozone-depleting or greenhouse-warming coolants.

Enye indlela kwezi ndlela zokupholisa amandla ngamandla yi-PDRC, into apho iindawo ezipholileyo ziphola ngokuzenzekelayo ngokubonisa ukukhanya kwelanga kunye nokutshisa ubushushu kwimozulu epholileyo.Ukuba umphezulu ubonakalisa ilanga (R) unokunciphisa ukwanda kobushushu belanga, kunye ngeqondo eliphezulu le-thermal radiation (Ɛ) inokunyusa isibhakabhaka sokuphulukana nobushushu, i-PDRC isebenze kakhulu.Ukuba iR kunye no-Ɛ iphakame ngokwaneleyo, nokuba ilahleko yokushisa kobushushu iya kwenzeka elangeni.

Ukuphuhlisa uyilo olusebenzayo lwe-PDRC ngumceli mngeni: uninzi lwezixazululo zoyilo zakutshanje zinzima okanye ziyabiza, kwaye azinakho ukuphunyezwa ngokubanzi okanye zisetyenziswe eluphahleni nakwizakhiwo ezinobume obahlukeneyo kunye noburhabaxa Ukuza kuthi ga ngoku, ngexabiso eliphantsi kwaye kulula ukufaka ipeyinti emhlophe kuye kwaba luphawu lwePRC. Nangona kunjalo, iingubo ezimhlophe zihlala zinee-pigments ezifunxa ukukhanya kwe-ultraviolet kwaye azibonisi ubude obude belanga, ngenxa yoko ukusebenza kwazo kumodareyitha kuphela.

Abaphandi bobunjineli baseColumbia baqulunqe ukusebenza okuphezulu kwe-PDRC yokugquma nge-nanometer-to micron-scale air gaps ezinokusetyenziswa njengomoya opholileyo kwaye zinokudaywa zipeyintwe eluphahleni, kwizakhiwo, kwiitanki zamanzi, kwizithuthi, nakwiziphekepheke - nantoni na enokupeyintwa basebenzise isisombululo esisekwe kwisiseko sobuchule ukunika iPolymer ubume obunje ngegwebu Ngenxa yomahluko kwisalathiso sokuphinda ubonakalise phakathi komoya opholileyo kunye nepolymer ejikelezileyo. Ukusasazeka kwaye kubonakalise ukukhanya kwelanga. I-Polymer yenza mhlophe kwaye ke kuthintele ukufudumeza kwelanga, ngelixa ubume bayo obuyimfihlakalo buvumela ukuba bukhanye ngokufanelekileyo ubushushu esibhakabhakeni.
