Imodyuli yokunyakaza enembile kakhulu: Isisekelo sokunemba kwe-granite VS isisekelo se-cast.

Ekusetshenzisweni kwemodyuli yokunyakaza enembile kakhulu, isisekelo, njengengxenye eyinhloko esekelayo, sidlala indima ebalulekile ekusebenzeni kwemodyuli. Isisekelo sokunemba kwe-granite kanye nesisekelo se-cast sinezimpawu zazo, futhi umehluko phakathi kwazo usobala.
I. Ukuqina
I-Granite ngemva kwezigidi zeminyaka yezinguquko ze-geological, isakhiwo sangaphakathi siminyene futhi sifana, ikakhulukazi yi-quartz, i-feldspar kanye nezinye izimbiwa ezihlanganiswe eduze. Lesi sakhiwo esiyingqayizivele sinikeza ukuzinza okuhle kakhulu futhi singamelana ngempumelelo nokuphazamiseka kwangaphandle. Eshabhu lokukhiqiza ama-chip kagesi, imishini engaphandle isebenza njalo, futhi isisekelo se-granite singanciphisa ubukhulu bokudlidliza kwemodyuli yokunyakaza eqondile kakhulu edluliselwa emoyeni nge-float engaphezu kuka-80%, okuqinisekisa ukunyakaza okubushelelezi kwemodyuli futhi kunikeze isiqinisekiso esiqinile sezinqubo ezinembile kakhulu njenge-lithography kanye nokuqoshwa kokukhiqiza ama-chip.

Nakuba isisekelo sokuphonsa singavimba ukudlidliza ngezinga elithile, kungase kube neziphambeko ezithile njengemigodi yesihlabathi kanye nemigodi enqubweni yokuphonsa, okuzonciphisa ukufana nokuzinza kwesakhiwo. Uma sibhekene nokudlidliza okuvama kakhulu namandla aphezulu, ikhono lokunciphisa ukudlidliza alilihle njengesisekelo se-granite, okuholela ekuzinzeni okungekuhle kokunyakaza kwemojuli yokunyakaza enembile kakhulu ye-air float, okuthinta ukunemba kokucubungula nokuthola imishini.
Okwesibili, ukugcinwa kokunemba
I-coefficient yokwandisa ukushisa kwe-granite iphansi kakhulu, ngokuvamile ku-5-7 × 10⁻⁶/℃, endaweni yokushintshashintsha kwezinga lokushisa, ushintsho losayizi luncane. Emkhakheni wezinkanyezi, imodyuli yokunyakaza enembile kakhulu yokulungisa kahle ilensi yesibonakude ihambisana nesisekelo se-granite, noma ngabe umehluko wokushisa phakathi kwemini nobusuku mkhulu, ingaqinisekisa ukuthi ukunemba kokubekwa kwelensi kugcinwa ezingeni le-sub-micron, kusize izazi zezinkanyezi ukuthi zibone ngokucacile izidalwa zasezulwini ezikude.
Izinto zensimbi ezisetshenziswa kakhulu njengensimbi ephothiwe, i-coefficient yokwandisa ukushisa iphakeme kakhulu, cishe i-10-20 × 10⁻⁶/℃. Lapho izinga lokushisa lishintsha, usayizi uyashintsha ngokusobala, okulula ukubangela ukuguqulwa kokushisa kwemoduli yokunyakaza enembile kakhulu ye-air float, okuholela ekunciphiseni ukunemba kokunyakaza. Enqubweni yokugaya ilensi ye-optical ezwela izinga lokushisa, ukuguqulwa kwesisekelo sensimbi ephothiwe ngaphansi kwethonya lokushisa kungabangela ukuphambuka kokunemba kokugaya ilensi ngale kwebanga elivunyelwe futhi kuthinte ikhwalithi yelensi.
Okwesithathu, ukumelana nokuguguleka
Ubulukhuni be-granite buphezulu, ubulukhuni be-Mohs bungafinyelela ku-6-7, ukumelana okuqinile kokuguguleka. Elabhorethri yesayensi yezinto zokwakha, imodyuli yokunyakaza evame ukusetshenziswa kakhulu yokuntanta emoyeni, isisekelo se-granite singamelana ngempumelelo nokungqubuzana kwesilayida sokuntanta emoyeni, uma kuqhathaniswa nesisekelo esivamile, singandisa umjikelezo wokugcinwa kwemodyuli ngaphezu kuka-50%, sinciphise izindleko zokugcinwa kwemishini, futhi siqinisekise ukuqhubeka komsebenzi wocwaningo lwesayensi.
Uma isisekelo sokubumba senziwe ngezinto zensimbi ezivamile, ubulukhuni buphansi kakhulu, futhi ubuso kulula ukubugqoka ngaphansi kokungqubuzana kwesikhathi eside okuphindaphindayo kwesilayida sokuntanta emoyeni, okuthinta ukunemba kokunyakaza kanye nokushelela kwemodyuli yokunyakaza enembile kakhulu ye-air float, edinga ukulungiswa kanye nokushintshwa njalo, okwandisa izindleko zokusebenzisa kanye nesikhathi sokuphumula.
Okwesine, izindleko zokukhiqiza kanye nobunzima bokucubungula
Izindleko zokuthola izinto zokusetshenziswa zegranite ziphezulu, ukumba, ukuthutha okuyinkimbinkimbi, ukucubungula kudinga imishini nobuchwepheshe bochwepheshe, njengokusika okunembe kakhulu, ukugaya, ukupholisha, njll., izindleko zokukhiqiza eziphakeme. Futhi ngenxa yobulukhuni bayo obuphezulu, ukuphuka, ubunzima bokucubungula, ukubonakala kulula ukugoba komphetho, imifantu nezinye iziphambeko, izinga lokulahla izinto ezilahliwe liphezulu.
Izinto zokusetshenziswa eziyisisekelo sokuphonsa zitholakala kabanzi, izindleko ziphansi kakhulu, inqubo yokuphonsa isivuthiwe, ubunzima bokucubungula buncane, futhi ukukhiqizwa ngobuningi kungenziwa ngesikhunta, ngokusebenza kahle kokukhiqiza okuphezulu kanye nezindleko ezingalawuleki. Kodwa-ke, ukuze kufezwe ukunemba okuphezulu kanye nokuzinza okufanayo nesisekelo se-granite, inqubo yokuphonsa kanye nezidingo zangemva kokucubungula ziqinile kakhulu, futhi izindleko nazo zizokhuphuka kakhulu.
Ngamafuphi, isisekelo sokunemba kwe-granite sinenzuzo enkulu ezimweni zokusetshenziswa kwamamojula okunyakaza anembile kakhulu anokunemba okuphezulu, ukuzinza kanye nokumelana nokuguguleka. Isisekelo sokukhipha sinezinzuzo ezithile ekulula kwezindleko kanye nokucubungula, futhi sifaneleka ngezikhathi lapho isidingo sokunemba siphansi khona futhi kulandelwa ukuphishekela ukusebenza kahle kwezindleko.
