Incazelo:
Uma ukukhanya kwelanga kushaya phezu kwento, into idonsa amandla okukhanya aseduze ne-infrared ukuze ikhulise izinga lokushisa elingaphezulu, futhi amandla okukhanya okuseduze ne-infrared ahlanganisa u-50% wawo wonke amandla okukhanya kwelanga.Ehlobo, lapho ilanga likhanya phezu kwento, izinga lokushisa elingaphezulu lingafinyelela ku-70~80℃.Ngalesi sikhathi, ukukhanya kwe-infrared kudinga ukuboniswa ukuze kuncishiswe izinga lokushisa elingaphezulu lento;lapho izinga lokushisa liphansi ebusika, ukukhanya kwe-infrared kudinga ukudluliselwa ukuze kulondolozwe ukushisa.Okusho ukuthi, kunesidingo sempahla yokulawula izinga lokushisa ehlakaniphile engabonisa ukukhanya kwe-infrared emazingeni okushisa aphezulu, kodwa idlulise ukukhanya kwe-infrared emazingeni okushisa aphansi futhi idlulisele ukukhanya okubonakalayo ngesikhathi esifanayo, ukuze yonge amandla futhi ivikele imvelo.
I-Vanadium dioxide (VO2) iyi-oxide esebenza ngokushintsha isigaba eduze kuka-68°C.Kungacatshangwa ukuthi uma i-VO2 powder material enomsebenzi wokushintsha isigaba ihlanganiswa ku-base material, bese ihlanganiswa nezinye izingulube nama-filler, inhlanganisela ehlakaniphile yokulawula izinga lokushisa esekelwe ku-VO2 ingenziwa.Ngemuva kokuthi ubuso bento buhlanganiswe nalolu hlobo lopende, lapho izinga lokushisa langaphakathi liphansi, ukukhanya kwe-infrared kungangena ngaphakathi;lapho izinga lokushisa likhuphukela ekushiseni kwenguquko yesigaba esibucayi, ukuguqulwa kwesigaba kwenzeka, futhi ukuhanjiswa kokukhanya kwe-infrared kuncipha futhi izinga lokushisa langaphakathi liyancipha kancane kancane;Uma izinga lokushisa lehlela ezingeni elithile lokushisa, i-VO2 iba noshintsho lwesigaba esihlanekezelwe, futhi ukukhanya kwe-infrared kuyanda futhi, ngaleyo ndlela kuqaphele ukulawulwa kwezinga lokushisa okuhlakaniphile.Kungabonakala ukuthi isihluthulelo sokulungiselela izigqoko zokulawula izinga lokushisa ezihlakaniphile ukulungisa i-VO2 powder ngomsebenzi wokushintsha kwesigaba.
Ku-68℃, i-VO2 ishintsha ngokushesha isuka ku-semiconductor enezinga lokushisa eliphansi, i-antiferromagnetic, kanye nesigaba se-rutile monoclinic esihlanekezelwe njenge-MoO2 siye esigabeni se-metallic, i-paramagnetic, ne-rutile tetragonal yezinga lokushisa eliphezulu, futhi isibopho se-VV sangaphakathi siyashintsha Kuyisibopho sensimbi. , yethula isimo se-metallic, umphumela wokuqhuba wama-electron wamahhala uthuthukiswa ngokucijile, futhi izici zokukhanya zishintsha kakhulu.Lapho izinga lokushisa liphakeme kunephuzu lokushintsha kwesigaba, i-VO2 isesimweni sensimbi, indawo yokukhanya ebonakalayo ihlala isobala, indawo yokukhanya kwe-infrared icwebezela kakhulu, futhi ingxenye yokukhanya kwe-infrared yemisebe yelanga ivimbelwe ngaphandle, kanye nokudluliswa kwe-infrared ukukhanya kwe-infrared kuncane;Lapho iphuzu lishintsha, i-VO2 isesimweni se-semiconductor, futhi isifunda ukusuka ekukhanyeni okubonakalayo kuya ekukhanyeni kwe-infrared sibonisa ngale ngokusesilinganisweni, okuvumela imisebe yelanga eminingi (kuhlanganise nokukhanya okubonakalayo nokukhanya kwe-infrared) ukungena ekamelweni, ngokudluliswa okuphezulu, futhi lolu shintsho buyisela emuva.
Ezisetshenziswa ezingokoqobo, izinga lokushisa lokushintsha kwesigaba elingu-68°C lisephezulu kakhulu.Indlela yokunciphisa izinga lokushisa lokushintsha kwesigaba ekamelweni lokushisa kuyinkinga wonke umuntu ayikhathalelayo.Njengamanje, indlela eqondile yokunciphisa izinga lokushisa lokushintsha kwesigaba i-doping.
Njengamanje, iningi lezindlela zokulungiselela i-VO2 ene-doped i-doping eyodwa, okungukuthi, i-molybdenum noma i-tungsten kuphela efakwe i-doped, futhi kunemibiko embalwa mayelana ne-doping kanyekanye yezinto ezimbili.I-Doping izakhi ezimbili ngesikhathi esifanayo ayikwazi nje ukunciphisa izinga lokushisa lokuguqulwa kwesigaba, kodwa futhi ithuthukise ezinye izakhiwo ze-powder.
