Xa ukukhanya kwelanga kubetha umphezulu wento, into ubukhulu becala ifunxa amandla okukhanya akufuphi ne-infrared ukwandisa ubushushu bomphezulu wayo, kwaye amandla okukhanya akufuphi ne-infrared athatha i-50% yamandla ewonke okukhanya kwelanga.Ehlotyeni, xa ilanga likhanya phezu kwento, ubushushu bomphezulu bunokufikelela ku-70~80℃.Ngeli xesha, ukukhanya kwe-infrared kufuneka kubonakaliswe ukunciphisa ubushushu bomphezulu bento;xa iqondo lobushushu lisezantsi ebusika, ukukhanya kwe-infrared kufuneka kudluliswe ukuze kugcinwe ubushushu.Okokuthi, kukho imfuneko yezinto ezihlakaniphile zokulawula ubushushu obunokubonakalisa ukukhanya kwe-infrared kumaqondo aphezulu, kodwa ukuhambisa ukukhanya kwe-infrared kumaqondo aphantsi kunye nokuhambisa ukukhanya okubonakalayo ngexesha elifanayo, ukwenzela ukugcina amandla nokukhusela indalo.
I-Vanadium diokside (VO2) yioksidi enomsebenzi wokutshintsha isigaba esikufutshane ne-68°C.Kucingelwa ukuba ukuba i-VO2 powder impahla kunye nomsebenzi wokutshintsha kwesigaba idityaniswe kwizinto ezisisiseko, kwaye emva koko ixutywe nezinye ii-pigments kunye nezizaliso, i-composite yokulawula ukushisa okuhlakaniphileyo yokulawula ubushushu ngokusekelwe kwi-VO2 inokwenziwa.Emva kokuba ubuso bento bufakwe ngolu hlobo lwepeyinti, xa ukushisa kwangaphakathi kuphantsi, ukukhanya kwe-infrared kungangena ngaphakathi;xa iqondo lokushisa liphakama kwiqondo lokushisa elibalulekileyo lokutshintsha, utshintsho lwesigaba luyenzeka, kwaye ukukhanya kwe-infrared kuyancipha kwaye ukushisa kwangaphakathi kuyancipha kancane kancane;Xa iqondo lobushushu lehla ukuya kubushushu obuthile, i-VO2 iphinda itshintshe, kwaye i-infrared light transmittance iyanda kwakhona, ngaloo ndlela iqonda ulawulo lobushushu obukrelekrele.Ingabonwa ukuba isitshixo sokulungiselela iingubo zokulawula ukushisa okuhlakaniphile kukulungiselela i-VO2 powder kunye nomsebenzi wokutshintsha isigaba.
Kwi-68℃, i-VO2 itshintsha ngokukhawuleza ukusuka kwi-semiconductor yobushushu obuphantsi, i-antiferromagnetic, kunye ne-MoO2-efana ne-rutile monoclinic egqwethekileyo isigaba ukuya kwinqanaba eliphezulu lobushushu bentsimbi, i-paramagnetic, kunye nesigaba se-rutile tetragonal, kunye ne-VV yangaphakathi yokutshintsha ibhondi Yibhondi yentsimbi. , ebonisa i-metallic state, i-conduction effect ye-electrons yamahhala iphuculwe ngokukhawuleza, kwaye iipropati ezibonakalayo zitshintsha kakhulu.Xa iqondo lobushushu liphezulu kunendawo yokutshintsha kwesigaba, i-VO2 ikwimeko yesinyithi, indawo yokukhanya ebonakalayo ihlala elubala, indawo yokukhanya kwe-infrared ibonakalisa kakhulu, kwaye indawo yokukhanya kwe-infrared yemitha yelanga ivalwe ngaphandle, kunye nokuhanjiswa kwe-infrared. ukukhanya kwe-infrared kuncinci;Xa inqaku litshintsha, i-VO2 ikwimeko ye-semiconductor, kwaye ummandla ukusuka ekukhanyeni okubonakalayo ukuya ekukhanyeni kwe-infrared kukhanya ngokuphakathi, okuvumela ukuba uninzi lwemitha yelanga (kubandakanywa ukukhanya okubonakalayo kunye nokukhanya kwe-infrared) ukungena kwigumbi, kunye nokuhanjiswa okuphezulu, kwaye olu tshintsho buyela umva.
Ukusetyenziswa okusebenzayo, iqondo lobushushu besigaba se-68 ° C lisephezulu kakhulu.Indlela yokunciphisa ubushushu besigaba sokutshintsha kwiqondo lokushisa yingxaki ekhathalelwa ngumntu wonke.Okwangoku, eyona ndlela ichanekileyo yokunciphisa ubushushu benguqu yesigaba yi-doping.
Okwangoku, uninzi lweendlela zokulungiselela i-VO2 ye-doped yi-doping eyodwa, oko kukuthi, i-molybdenum okanye i-tungsten kuphela i-doped, kwaye kukho iingxelo ezimbalwa kwi-doping ngaxeshanye yezinto ezimbini.I-Doping izinto ezimbini ngexesha elifanayo azikwazi ukunciphisa kuphela ubushushu benguqu yesigaba, kodwa nokuphucula ezinye iimpawu zepowder.
