Izizathu ezininzi zokuba kutheni oomatshini bokugquma be-perovskite bexhomekeke kwiziseko ze-granite
Uzinzo olubalaseleyo
Inkqubo yokugquma i-perovskite ineemfuno eziphezulu kakhulu zokuzinza kwezixhobo. Nokuba kukungcangcazela okanye ukufuduka okuncinci kunokukhokelela kubukhulu bokugquma obungalinganiyo, nto leyo echaphazela umgangatho weefilimu ze-perovskite kwaye ekugqibeleni inciphise ukusebenza kakuhle kokuguqulwa kwebhetri ngefotoelectric. I-Granite inoxinano olufikelela kwi-2.7-3.1g/cm³, iqinile kwimo yayo, kwaye inokubonelela ngenkxaso ezinzileyo kumatshini wokugquma. Xa kuthelekiswa neziseko zesinyithi, iziseko ze-granite zinokunciphisa ngempumelelo ukuphazamiseka kokungcangcazela kwangaphandle, okufana nokungcangcazela okubangelwa kukusebenza kwezinye izixhobo kunye nokuhamba kwabasebenzi kumzi-mveliso. Emva kokuba kuncitshiswe sisiseko se-granite, ukungcangcazela okudluliselwe kwiindawo eziphambili zomatshini wokugquma akunamsebenzi, okuqinisekisa inkqubela phambili ezinzileyo yenkqubo yokugquma.
I-coefficient ephantsi kakhulu yokwandiswa kobushushu
Xa umatshini wokugquma i-perovskite usebenza, ezinye izinto ziya kuvelisa ubushushu ngenxa yomsebenzi owenziwe kukungqubana kwamandla kagesi kunye noomatshini, nto leyo ebangela ukuba ubushushu bezixhobo bunyuke. Okwangoku, ubushushu obujikeleze indawo yokusebenza bunokutshintshatshintsha ukuya kwinqanaba elithile. Ubungakanani bezinto eziqhelekileyo buya kutshintsha kakhulu xa ubushushu butshintshatshintsha, nto leyo ebulalayo kwiinkqubo zokugquma i-perovskite ezifuna ukuchaneka kwe-nanoscale. I-coefficient yokwandiswa kobushushu be-granite iphantsi kakhulu, malunga (4-8) ×10⁻⁶/℃. Xa ubushushu butshintshatshintsha, ubungakanani bayo buyatshintsha kancinci kakhulu.
Uzinzo oluhle lweekhemikhali
Izisombululo zePerovskite precursor zihlala zine-reactivity ethile yeekhemikhali. Ngexesha lenkqubo yokugquma, ukuba uzinzo lweekhemikhali zezinto ezisisiseko sezixhobo alulunganga, lunokungenelela kwiikhemikhali kunye nesisombululo. Oku akungcolisi nje kuphela isisombululo, okuchaphazela ukwakheka kweekhemikhali kunye nokusebenza kwefilimu yeperovskite, kodwa kunokonakalisa isiseko, kufinyeze ubomi benkonzo yesixhobo. I-Granite yenziwe kakhulu ngeeminerali ezifana ne-quartz kunye ne-feldspar. Ineempawu zeekhemikhali ezizinzileyo kwaye iyamelana nokugqwala kwe-asidi kunye ne-alkali. Xa idibana nezisombululo ze-perovskite precursor kunye nezinye ii-reagents zeekhemikhali kwinkqubo yemveliso, akukho ziphumo zeekhemikhali ezenzekayo, okuqinisekisa ubunyulu bendawo yokugquma kunye nokusebenza okuzinzileyo kwexesha elide kwesixhobo.
Iimpawu zokudambisa eziphezulu zinciphisa impembelelo yokungcangcazela
Xa umatshini wokugquma usebenza, ukuhamba kwezinto zangaphakathi zoomatshini kunokubangela ukungcangcazela, njengokunyakaza okubuyelana kwentloko yokugquma kunye nokusebenza kwemoto. Ukuba ezi ngcangcazela azinakuncitshiswa ngexesha, ziya kusasazeka kwaye zigqume ngaphakathi kwesixhobo, nto leyo echaphazela ngakumbi ukuchaneka kokugquma. I-Granite ineempawu zokugquma eziphezulu, kunye nomlinganiselo wokugquma ngokubanzi ukusuka kwi-0.05 ukuya kwi-0.1, ophindwe kaninzi kunezixhobo zesinyithi.
Imfihlakalo yobugcisa yokufikelela kwi-±1μm flatness kwisakhelo se-gantry esine-span ezili-10
Itekhnoloji yokucubungula echanekileyo kakhulu
Ukuze kufunyanwe ubume obuyi-±1μm kwifreyimu ye-gantry ye-span ezili-10, iindlela eziphambili zokucubungula ezichanekileyo kufuneka zisetyenziswe kuqala kwinqanaba lokucubungula. Umphezulu wefreyimu ye-gantry uphathwa kakuhle ngeendlela zokugaya nokupolisha ezichanekileyo kakhulu.
Inkqubo yokufumanisa ephucukileyo kunye nempendulo
Kwinkqubo yokuvelisa nokufakela iifreyimu ze-gantry, kubalulekile ukuba uxhotyiswe ngezixhobo zokufumanisa eziphambili. I-interferometer yelaser inokulinganisa ukuphambuka okuthe tyaba kwenxalenye nganye yefreyimu ye-gantry ngexesha langempela, kwaye ukuchaneka kwayo kokulinganisa kunokufikelela kwinqanaba le-sub-micron. Idatha yokulinganisa iya kubuyiselwa kwinkqubo yolawulo ngexesha langempela. Inkqubo yolawulo ibala indawo kunye nobungakanani obufuna ukulungiswa ngokusekelwe kwidatha yempendulo, ize ilungise ifreyimu ye-gantry ngesixhobo sokulungisa kakuhle esichanekileyo.
Uyilo lwesakhiwo olulungiselelwe kakuhle
Uyilo olufanelekileyo lwesakhiwo lunceda ekuphuculeni ukuqina kunye nokuzinza kwesakhelo se-gantry kunye nokunciphisa ukuguquguquka okubangelwa bubunzima baso kunye nemithwalo yangaphandle. Ulwakhiwo lwesakhelo se-gantry luye lwalinganiswa kwaye lwahlalutywa ngokusebenzisa isoftware yohlalutyo lwezinto ezilinganiselweyo ukuze kuphuculwe imo, ubungakanani kunye nendlela yoqhagamshelo lwe-cross-sectional beam kunye nekholamu. Umzekelo, ii-cross beams ezinee-cross-sections ezimile okwebhokisi zinokumelana okunamandla okujika kunye nokugoba xa kuthelekiswa nee-I-beams eziqhelekileyo, kwaye zinokunciphisa ngempumelelo ukuguquguquka kwi-10-meter span. Okwangoku, iimbambo zokuqinisa zongezwa kwiindawo ezibalulekileyo ukuze kuphuculwe ukuqina kwesakhelo, ukuqinisekisa ukuba ukuqina kwesakhelo se-gantry kusenokugcinwa ngaphakathi kwe-±1μm xa kuthwaxwa yimithwalo eyahlukeneyo ngexesha lokusebenza komatshini wokugquma.
Ukukhethwa kunye nokucutshungulwa kwezinto
Isiseko segranite somatshini wokugquma i-perovskite, kunye nozinzo lwaso, i-coefficient ephantsi yokwandiswa kobushushu, uzinzo lweekhemikhali kunye neempawu zokudambisa eziphezulu, sinika isiseko esiqinileyo sokugquma okuchanekileyo. Isakhelo se-gantry esine-span ezili-10 sifikelele kwi-flatness ephezulu kakhulu ye-±1μm ngokusebenzisa uthotho lweendlela zobugcisa ezifana neendlela zokucubungula ezichanekileyo, iinkqubo zokufumanisa eziphambili kunye nempendulo, uyilo oluphuculweyo lwesakhiwo, kunye nokukhethwa kwezinto kunye nonyango, kunye nokukhuthaza ukuveliswa kweeseli zelanga ze-perovskite ukuze zihambele phambili ekusebenzeni okuphezulu kunye nomgangatho ophezulu.
