Izizathu ezininzi zokuba kutheni oomatshini bokugquma be-perovskite baxhomekeke kwiziseko zegranite
Uzinzo olubalaseleyo
Inkqubo yokugquma i-perovskite ineemfuno eziphezulu kakhulu zokuzinza kwezixhobo. Nokuba ukungcangcazela okuncinci okanye ukufuduswa kungakhokelela kubunzima obungalinganiyo bokugquma, nto leyo echaphazela umgangatho weefilimu ze-perovskite kwaye ekugqibeleni kunciphisa ukusebenza kakuhle kokuguqulwa kwefoto yombane webhetri. I-Granite inoxinano oluya kutsho kwi-2.7-3.1g/cm³, iqinile ngokwesimo, kwaye inokubonelela ngenkxaso ezinzileyo kumatshini wokugquma. Xa kuthelekiswa neziseko zetsimbi, iziseko zegranite zinokunciphisa ngokufanelekileyo ukuphazanyiswa kweentshukumo zangaphandle, ezifana neengqungquthela eziveliswa kukusebenza kwezinye izixhobo kunye nokuhamba kwabasebenzi kwifektri. Emva kokuthotywa kwesiseko se-granite, ii-vibrations ezithunyelwa kumacandelo angundoqo omatshini wokugquma azinanto, ziqinisekisa inkqubela ezinzileyo yenkqubo yokugquma.
I-coefficient ephantsi kakhulu yokwandiswa kwe-thermal
Xa umatshini wokugquma we-perovskite usebenza, amanye amacandelo aya kuvelisa ubushushu ngenxa yomsebenzi owenziwe yi-friction yangoku kunye nomatshini, obangela ukuba ukushisa kwezixhobo kunyuke. Ngeli xesha, ubushushu be-ambient kwiworkshop yemveliso bunokuguquguquka ukusa kwinqanaba elithile. Ubungakanani bezinto eziqhelekileyo buya kutshintsha kakhulu xa iqondo lokushisa lihluka, elibulalayo kwiinkqubo zokugqoka i-perovskite ezifuna ukuchaneka kwe-nanoscale. I-coefficient yokwandiswa kwe-thermal ye-granite iphantsi kakhulu, malunga (4-8) × 10⁻⁶/℃. Xa iqondo lobushushu liguquguquka, ubukhulu balo butshintsha kakhulu.
Uzinzo oluhle lweekhemikhali
Izisombululo ze-Perovskite precursor zihlala zinekhemikhali ethile yokuphinda isebenze. Ngexesha lenkqubo yokugquma, ukuba ukuzinza kweekhemikhali zezinto ezisisiseko sezixhobo zihlwempuzekile, kunokungena kwi-chemical reaction kunye nesisombululo. Oku akugcini nje ukungcolisa isisombululo, esichaphazela ukubunjwa kweekhemikhali kunye nokusebenza kwefilimu ye-perovskite, kodwa inokugqwesa isiseko, inciphise ubomi benkonzo yezixhobo. Igranite ikakhulu yenziwe ngamaminerali afana nequartz kunye nefeldspar. Ineempawu zeekhemikhali ezizinzile kwaye iyamelana ne-asidi kunye ne-alkali corrosion. Xa idibana nezisombululo ze-precursor ye-perovskite kunye nezinye i-reagents zamachiza kwinkqubo yokuvelisa, akukho zimpendulo zekhemikhali ezenzekayo, ziqinisekisa ukucoceka kwendawo yokugubungela kunye nokusebenza okuzinzile kwexesha elide lezixhobo.
Iimpawu zokudambisa eziphezulu zinciphisa impembelelo ye-vibration
Xa umatshini wokugquma usebenza, ukuhamba kwamacandelo omatshini angaphakathi kunokubangela ukungcangcazela, njengokujikeleza okuphindaphindiweyo kwentloko yokugubungela kunye nokusebenza kwemoto. Ukuba ezi vibrations azikwazi ukuthotywa ngexesha, ziya kusasaza kwaye zigqithise ngaphakathi kwesixhobo, zichaphazela ngakumbi ukuchaneka kwengubo. I-Granite inophawu oluphezulu lokudambisa, kunye nomlinganiselo wokudambisa ngokubanzi ukusuka ku-0.05 ukuya ku-0.1, nto leyo ephindaphindwe kaninzi kunemathiriyeli yesinyithi.
Imfihlakalo yobuchwephesha yokuzuza ±1μm flatness kwi-10-span gantry frame
Itekhnoloji yokulungiswa okuphezulu
Ukufikelela kwi-flatness ye-± 1μm yefreyimu ye-gantry ye-10-span, ubugcisa obuphezulu bokuchaneka obuphezulu kufuneka bamkelwe kuqala kwinqanaba lokucubungula. Umphezulu wesakhelo se-gantry uphathwa ngokucokisekileyo ngokusebenzisa iindlela ezichanekileyo zokusila kunye nokupolisha.
Ukufunyaniswa okuphezulu kunye nenkqubo yempendulo
Kwinkqubo yokuvelisa kunye nofakelo lwezakhelo ze-gantry, kubalulekile ukuxhotyiswa ngezixhobo zokubona eziphambili. I-laser interferometer inokulinganisa ukuphambuka kwe-flatness yecandelo ngalinye lesakhelo se-gantry ngexesha langempela, kwaye ukuchaneka kokulinganisa kwayo kunokufikelela kwinqanaba le-sub-micron. Idatha yokulinganisa iya kubuyiselwa kwinkqubo yokulawula ngexesha langempela. Inkqubo yokulawula ibala indawo kunye nobungakanani obufuna ukulungiswa ngokusekelwe kwidatha yengxelo, kwaye emva koko ilungelelanise isakhelo se-gantry ngesixhobo esichanekileyo esichanekileyo.
Uyilo lwesakhiwo olulungiselelwe
Uyilo lwesakhiwo olunengqiqo lunceda ukunyusa ukuqina kunye nokuzinza kwesakhelo se-gantry kunye nokunciphisa i-deformation ebangelwa ubunzima bayo kunye nemithwalo yangaphandle. Ulwakhiwo lwesakhelo se-gantry safaniswa kwaye sahlalutywa ngokusebenzisa isoftware yohlalutyo olunqamlekileyo ukuze kulungiswe ubume obunqamlezayo, ubungakanani kunye nendlela yokudibanisa ye-crossbeam kunye nekholomu. Umzekelo, imiqadi enqamlezileyo enamacandelo anqamlezileyo enziwe ngebhokisi inokuqina okuqinileyo kunye nokugoba xa kuthelekiswa nemigangatho ye-I eqhelekileyo, kwaye inokunciphisa ngokufanelekileyo i-deformation kwisithuba seemitha ezili-10. Okwangoku, iimbambo zokuqinisa zongezwa kwiindawo eziphambili ukuqhubela phambili ukuqinisa ukuqina kwesakhiwo, ukuqinisekisa ukuba i-flatness yefreyimu ye-gantry isenokugcinwa ngaphakathi kwe-± 1μm xa iphantsi kwemithwalo eyahlukeneyo ngexesha lokusebenza komatshini wokugubungela.
Ukukhethwa kunye nokulungiswa kwezinto
Isiseko se-granite somatshini wokugquma we-perovskite, kunye nokuzinza kwayo, i-coefficient ephantsi yokwandiswa kwe-thermal, ukuzinza kweekhemikhali kunye neempawu eziphezulu zokumanzisa, kunika isiseko esiqinileyo sokutya okuchanekileyo. Isakhelo se-gantry se-10-span siye safumana i-ultra-high flatness ye-± 1μm ngokusebenzisa uchungechunge lweendlela zobugcisa ezifana neendlela eziphezulu zokuchaneka, ukufumanisa okuphambili kunye neenkqubo zokuphendula, ukucwangciswa kwesakhiwo esilungisiweyo, kunye nokukhethwa kwezinto kunye nonyango, ngokudibeneyo ukukhuthaza ukuveliswa kweeseli zelanga ze-perovskite ukuqhubela phambili ekusebenzeni okuphezulu kunye nomgangatho ophezulu.
