Izizathu eziningi zokuthi kungani imishini yokumboza i-perovskite ithembele ezisekelweni ze-granite
Ukuqina okuvelele
Inqubo yokumboza i-perovskite inezidingo eziphakeme kakhulu zokuzinza kwemishini. Ngisho nokudlidliza okuncane noma ukufuduka kungaholela ekujiyeni okungalingani kokumboza, okuthinta ikhwalithi yamafilimu e-perovskite futhi ekugcineni kunciphisa ukusebenza kahle kokuguqulwa kwebhethri nge-photoelectric. I-Granite inobuningi obufinyelela ku-2.7-3.1g/cm³, iqinile ekuthungeni, futhi inganikeza ukwesekwa okuzinzile komshini wokumboza. Uma kuqhathaniswa nezisekelo zensimbi, izisekelo ze-granite zinganciphisa ngempumelelo ukuphazamiseka kokudlidliza kwangaphandle, njengokudlidliza okubangelwa ukusebenza kweminye imishini kanye nokuhamba kwabasebenzi efektri. Ngemva kokuncishiswa yisisekelo se-granite, ukudlidliza okudluliselwa ezingxenyeni eziyinhloko zomshini wokumboza akunamsebenzi, okuqinisekisa inqubekela phambili eqinile yenqubo yokumboza.
I-coefficient ephansi kakhulu yokwanda kokushisa
Uma umshini wokumboza we-perovskite usebenza, ezinye izingxenye zizokhiqiza ukushisa ngenxa yomsebenzi owenziwa ukungqubuzana kwamanje nokwemishini, okubangela ukuba izinga lokushisa lemishini likhuphuke. Okwamanje, izinga lokushisa elizungezile endaweni yokukhiqiza lingase lishintshe kakhulu ngezinga elithile. Usayizi wezinto ezivamile uzoshintsha kakhulu lapho izinga lokushisa lishintsha, okuyinto ebulalayo ezinqubweni zokumboza ze-perovskite ezidinga ukunemba kwe-nanoscale. I-coefficient yokwanda kokushisa kwe-granite iphansi kakhulu, cishe (4-8) ×10⁻⁶/℃. Uma izinga lokushisa lishintshashintsha, usayizi walo ushintsha kancane kakhulu.
Ukuqina okuhle kwamakhemikhali
Izixazululo ze-Perovskite precursor zivame ukuba nokusabela okuthile kwamakhemikhali. Ngesikhathi senqubo yokumboza, uma ukuzinza kwamakhemikhali kwezinto eziyisisekelo semishini kukubi, kungase kubhekane nokusabela kwamakhemikhali nesixazululo. Lokhu akugcini nje ngokungcolisa ikhambi, kuthinte ukwakheka kwamakhemikhali kanye nokusebenza kwefilimu ye-perovskite, kodwa futhi kungalimaza isisekelo, kufinyeze impilo yenkonzo yemishini. I-Granite yakhiwe kakhulu ngamaminerali afana ne-quartz ne-feldspar. Inezakhiwo zamakhemikhali ezizinzile futhi imelana nokugqwala kwe-asidi ne-alkali. Uma ihlangana nezixazululo ze-perovskite precursor kanye nezinye izinto zamakhemikhali enqubweni yokukhiqiza, akukho ukusabela kwamakhemikhali okwenzekayo, okuqinisekisa ubumsulwa bendawo yokumboza kanye nokusebenza okuzinzile kwesikhathi eside kwemishini.
Izici zokudambisa okuphezulu zinciphisa umthelela wokudlidliza
Uma umshini wokumboza usebenza, ukunyakaza kwezingxenye zangaphakathi zemishini kungabangela ukudlidliza, njengokunyakaza okuphindaphindayo kwekhanda lokumboza kanye nokusebenza kwemoto. Uma lokhu kudlidliza kungenakuncishiswa ngesikhathi, kuzosakazeka futhi kungene ngaphakathi kwemishini, okuzothinta kakhulu ukunemba kokumboza. I-Granite inesici sokudambisa esiphakeme, esinesilinganiso sokudambisa ngokuvamile esisukela ku-0.05 kuya ku-0.1, okuphindwe kaningana kunezinto zensimbi.
Imfihlakalo yobuchwepheshe yokufinyelela ukuthamba okungu-±1μm kufreyimu ye-gantry engu-10-span
Ubuchwepheshe bokucubungula obunembile kakhulu
Ukuze kufezwe ukuthamba okungu-±1μm kohlaka lwe-gantry oluyi-span eyi-10, amasu okucubungula asezingeni eliphezulu kumele asetshenziswe kuqala esigabeni sokucubungula. Ubuso bohlaka lwe-gantry buphathwa kahle ngamasu okugaya nokupholisha anembile kakhulu.
Uhlelo lokuthola oluthuthukisiwe kanye nempendulo
Enqubweni yokukhiqiza nokufaka ozimele be-gantry, kubalulekile ukuhlonyiswa ngamathuluzi okuthola athuthukile. I-interferometer ye-laser ingalinganisa ukuphambuka okuyisicaba kwengxenye ngayinye yohlaka lwe-gantry ngesikhathi sangempela, futhi ukunemba kwayo kokulinganisa kungafinyelela ezingeni le-sub-micron. Idatha yokulinganisa izobuyiselwa ohlelweni lokulawula ngesikhathi sangempela. Uhlelo lokulawula lubala indawo kanye nobuningi obudinga ukulungiswa ngokusekelwe kudatha yempendulo, bese lulungisa uhlaka lwe-gantry ngedivayisi yokulungisa kahle enembile kakhulu.
Umklamo wesakhiwo olungiselelwe kahle
Ukwakheka kwesakhiwo okunengqondo kusiza ukuthuthukisa ukuqina nokuqina kohlaka lwe-gantry nokunciphisa ukuguquka okubangelwa isisindo salo kanye nemithwalo yangaphandle. Isakhiwo sohlaka lwe-gantry silingiswe futhi sahlaziywa ngokusebenzisa isofthiwe yokuhlaziya i-finite element ukuze kulungiselelwe ukuma kwe-cross-sectional, usayizi kanye nendlela yokuxhuma ye-crossbeam kanye nekholomu. Isibonelo, i-crossbeams ene-cross-sections efana nebhokisi inokumelana okunamandla kokugoba nokugoba uma kuqhathaniswa ne-I-beams evamile, futhi inganciphisa ngempumelelo ukuguquka endaweni engamamitha ayi-10. Okwamanje, izimbambo zokuqinisa zengezwa ezingxenyeni ezibalulekile ukuze kuthuthukiswe ukuqina kwesakhiwo, kuqinisekiswe ukuthi ukuqina kohlaka lwe-gantry kusengakwazi ukugcinwa ngaphakathi kuka-±1μm lapho kufakwa imithwalo eyahlukahlukene ngesikhathi sokusebenza komshini wokumboza.
Ukukhethwa kanye nokucutshungulwa kwezinto zokwakha
Isisekelo segranite somshini wokumboza i-perovskite, ngokuqina kwaso, i-coefficient ephansi yokwanda kokushisa, ukuqina kwamakhemikhali kanye nezici zokunciphisa umswakama ophezulu, kunikeza isisekelo esiqinile sokumboza okunembe kakhulu. Uhlaka lwe-gantry olunezikhawu eziyi-10 lufinyelele ukuqina okuphezulu kakhulu okungu-±1μm ngokusebenzisa uchungechunge lwezindlela zobuchwepheshe ezifana namasu okucubungula okunembe kakhulu, izinhlelo zokuthola ezithuthukisiwe kanye nezimpendulo, ukwakheka kwesakhiwo okwenziwe ngcono, kanye nokukhethwa kwezinto kanye nokwelashwa, okukhuthaza ngokubambisana ukukhiqizwa kwamaseli elanga e-perovskite ukuze kuqhubekele phambili ekusebenzeni kahle okuphezulu kanye nekhwalithi ephezulu.
