Izizathu eziningi zokuthi kungani imishini yokumboza i-perovskite incike ezisekelweni ze-granite
Ukuzinza okuvelele
Inqubo yokumboza i-perovskite inezidingo eziphezulu kakhulu zokuzinza kwemishini. Ngisho nokudlidliza okuncane noma ukugudluzwa kungase kuholele ekujikeni kwe-coating engalingani, okubuye kuthinte ikhwalithi yamafilimu e-perovskite futhi ekugcineni kunciphisa ukusebenza kahle kokuguqulwa kwe-photoelectric kwebhethri. I-Granite inokuminyana okufika ku-2.7-3.1g/cm³, iqinile ngokwakheka, futhi inganikeza ukusekela okuzinzile komshini wokumboza. Uma kuqhathaniswa nezisekelo zensimbi, izisekelo ze-granite zinganciphisa ngempumelelo ukuphazamiseka kokudlidliza kwangaphandle, njengokudlidliza okukhiqizwa ukusebenza kwezinye izinto zokusebenza kanye nokunyakaza kwabasebenzi efektri. Ngemva kokuncishiswa isisekelo se-granite, ukudlidliza okudluliselwa ezingxenyeni eziyinhloko zomshini wokumboza akunakwa, kuqinisekisa ukuqhubeka okuzinzile kwenqubo yokumboza. .
I-coefficient ephansi kakhulu yokunwetshwa kwe-thermal
Lapho umshini wokumboza we-perovskite usebenza, ezinye izingxenye zizokhiqiza ukushisa ngenxa yomsebenzi owenziwe ukungqubuzana kwamanje kanye nemishini, okwenza izinga lokushisa lemishini likhuphuke. Ngaleso sikhathi, izinga lokushisa le-ambient ku-workshop yokukhiqiza lingaguquguquka ngokwezinga elithile. Ubukhulu bezinto ezivamile buzoshintsha kakhulu lapho izinga lokushisa lihluka, elibulalayo ngezinqubo zokugqoka i-perovskite ezidinga ukunemba kwe-nanoscale. I-coefficient yokunwetshwa okushisayo kwegwadle iphansi kakhulu, cishe (4-8) ×10⁻⁶/℃. Lapho izinga lokushisa lishintshashintsha, ubukhulu balo bushintsha kancane kakhulu.
Ukuzinza okuhle kwamakhemikhali
Izixazululo ze-precursor ze-Perovskite zivame ukuba ne-chemical reactivity ethile. Ngesikhathi senqubo yokumboza, uma ukuzinza kwamakhemikhali ezinto eziyisisekelo zemishini kukubi, kungase kubhekane nokusabela kwamakhemikhali ngesixazululo. Lokhu akugcini nje ukungcolisa isisombululo, okuthinta ukwakheka kwamakhemikhali nokusebenza kwefilimu ye-perovskite, kodwa futhi kungase kudle isisekelo, kunciphise impilo yesevisi yemishini. I-Granite yakhiwe ikakhulukazi ngamaminerali afana ne-quartz ne-feldspar. Inezici zamakhemikhali ezinzile futhi imelana ne-asidi ne-alkali corrosion. Uma ihlangana nezixazululo ze-precursor ye-perovskite namanye ama-reagents amakhemikhali ohlelweni lokukhiqiza, akukho ukusabela kwamakhemikhali okwenzekayo, okuqinisekisa ukuhlanzeka kwemvelo yokugqoka kanye nokusebenza okuzinzile kwesikhathi eside kwemishini. .
Izici zokumanzisa okuphezulu zinciphisa umthelela wokudlidliza
Lapho umshini wokumboza usebenza, ukunyakaza kwezingxenye zemishini yangaphakathi kungabangela ukudlidliza, njengokunyakaza okuphindaphindiwe kwekhanda elimbozayo kanye nokusebenza kwemoto. Uma lokhu kudlidliza kungakwazi ukuncishiswa ngesikhathi, kuzosabalalisa futhi kuphakame kakhulu ngaphakathi kwemishini, kuphinde kuthinte ukunemba kokumboza. I-Granite inesici sokudambisa okuphezulu uma kuqhathaniswa, enesilinganiso sokumanzisa ngokuvamile esisuka ku-0.05 siye ku-0.1, esiphindwe izikhathi ezimbalwa kunezinto zensimbi.
Imfihlakalo yobuchwepheshe yokuzuza ukucaba okungu-±1μm kuzimele we-gantry we-span engu-10
Ubuchwepheshe bokucubungula okuphezulu
Ukuze kuzuzwe flatness engu-±1μm yohlaka lwe-gantry lwe-span 10, izindlela zokucubungula ezinembayo ezithuthukisiwe kufanele zamukelwe kuqala esigabeni sokucubungula. Ingaphezulu lefreyimu ye-gantry liphathwa kahle ngokusebenzisa amasu okugaya nokunemba okuphezulu.
Ukutholwa okuthuthukile nesistimu yempendulo
.
Enqubweni yokukhiqiza nokufakwa kwamafreyimu e-gantry, kubalulekile ukuhlonyiswa ngamathuluzi okubona athuthukile. I-laser interferometer ingakala ukuchezuka kwe-flatness kwengxenye ngayinye yefreyimu ye-gantry ngesikhathi sangempela, futhi ukunemba kwayo kokulinganisa kungafinyelela izinga le-sub-micron. Idatha yokulinganisa izobuyiselwa kusistimu yokulawula ngesikhathi sangempela. Isistimu yokulawula ibala indawo nenani elidinga ukulungiswa ngokusekelwe kudatha yempendulo, bese lilungisa uhlaka lwe-gantry ngedivayisi yokunemba okuphezulu.
Idizayini yesakhiwo elungiselelwe
Idizayini yesakhiwo enengqondo isiza ukuthuthukisa ukuqina nokuzinza kwefreyimu ye-gantry futhi inciphise ukuguqulwa okubangelwa isisindo sayo kanye nemithwalo yangaphandle. Isakhiwo se-gantry frame salingiswa futhi sahlaziywa kusetshenziswa isofthiwe yokuhlaziya isici esilinganiselwe ukuze kuthuthukiswe umumo wesigaba esiphambene, usayizi kanye nendlela yokuxhuma ye-crossbeam nekholomu. Isibonelo, ama-crossbeam anezigaba eziphambanayo ezimise okwebhokisi anokumelana okuqinile nokugoba uma kuqhathaniswa nemishayo ye-I evamile, futhi anganciphisa ngempumelelo ukuwohloka endaweni engamamitha ayi-10. Phakathi naleso sikhathi, izimbambo eziqinisayo zengezwa ezingxenyeni ezibalulekile ukuze kuqhutshekwe kuthuthukiswe ukuqina kwesakhiwo, ukuqinisekisa ukuthi flatness yefreyimu ye-gantry isengagcinwa ngaphakathi kwe-± 1μm uma ingaphansi kwemithwalo ehlukahlukene ngesikhathi sokusebenza komshini wokumboza. .
Ukukhethwa nokucubungula kwezinto
.
Isisekelo se-granite somshini wokumboza we-perovskite, ngokuzinza kwawo, i-coefficient ephansi yokwanda okushisayo, ukuzinza kwamakhemikhali kanye nezici eziphezulu zokuswakama, kunikeza isisekelo esiqinile sokugqoka okunembayo okuphezulu. Uhlaka lwe-gantry oluyi-10-span luzuze ukucaba okuphezulu okungu-±1μm ngochungechunge lwezindlela zobuchwepheshe ezifana namasu okucubungula okunemba okuphezulu, ukutholwa okuthuthukisiwe nezinhlelo zokuphendula, ukwakheka okuthuthukisiwe kwesakhiwo, nokukhethwa kwezinto kanye nokwelashwa, ukukhuthaza ngokuhlanganyela ukukhiqizwa kwamaseli elanga e-perovskite ukuze aqhubekele phambili ekusebenzeni kahle okuphezulu kanye nekhwalithi ephezulu.
