Umehluko we-Chermal Expension Coeffred Offeccience phakathi kwengxenye ye-Precisite ye-Granite kanye nengxenye ye-ceramic yokucophelela kanye nesicelo sayo kumishini ephezulu yokunemba
Ekuphokopheleni ukucaciswa okuphezulu nokuqina ensimini yezimboni, i-coefficient yokwanda okushisayo kwezinto zokwakha iba ukucatshangelwa okubalulekile. Izakhi ze-Precision Granite kanye nezinto zokunemba ze-Ceramic, njengoba izinhlobo ezimbili zezinto ezisetshenziswayo ezisetshenziswa kabanzi kumishini enokunemba ephezulu, umehluko wazo we-thermal ebabazekayo unomthelela omkhulu ekusebenzeni kwemishini.
Umehluko ekukhunjweni kokunwebeka okushisayo
Izakhi ze-Precision Granite:
I-Granite njengetshe lemvelo, i-coefficie ekhuphukayo eshisayo iphansi kakhulu, ngokuvamile phakathi kuka-8 × 10 ^ -6/ ℃ ~ 10 × 10 ^ -6 -6 / ℃. Lokhu kusho ukuthi lapho izinga lokushisa lishintsha, ukushintshwa kosayizi kwengxenye yegrenite kuncane, okulungele ukugcina ukuqina nokunemba kwemishini. Ngaphezu kwalokho, uGranite futhi unamandla amahle acindezelayo, ukuqina kanye nokumelana nokugqoka, okwenza kube yinto evame ukusetshenziswa kwemishini yokusebenza okunembayo, imibhede nezinye izinto ezibonakalayo.
Izakhi ze-Parcision Ceramic:
Ngokuphambene nalokho, i-coefficient of thermal ukwanda kwezakhi ze-ceramic ye-ceramic iphansi, imvamisa iphansi kakhulu kunaleyo yezinto zensimbi ezifana nensimbi engagqwali. Lokhu ku-coeffient okuphansi kokwanda okushisayo kwama-ceramics okunemba kukwenza ukuthi kugcinwe ukuqina okuphezulu okuphezulu nokunemba ngaphansi kwezinguquko zokushisa ngokweqile. Lokhu kubaluleke kakhulu emishini edinga ukusebenza ngezimo ezinengqondo eziphezulu isikhathi eside, njengezisetshenziswa ze-aerospace, amathuluzi okulinganisa ngokunemba, njll.
Umthelela emishini ephezulu yokunemba
Ukugcinwa ngokunemba:
Emishini enokunemba okuphezulu, noma yiluphi ushintsho oluncane lwesayizi lungaba nomthelela omkhulu ekusebenzeni okuphelele kwemishini. Izakhi ze-Precision Granite kanye ne-Precision Ceramic Izakhi, ngenxa ye-coeffient yazo ephansi yokwanda okushisayo, ziyakwazi ukugcina ushintsho oluncane olucijile lapho izinga lokushisa lishintsha, ngaleyo ndlela luqinisekise ukunemba kwesikhathi eside nokuqina kwemishini. Lokhu kubaluleke kakhulu emishini edinga ukulinganiswa okuphezulu okunembile, njengokuxhumanisa imishini yokulinganisa, imishini ye-lithography, njll.
Ukwenza umdlalo:
Emishini enokunemba okuphezulu, umdlalo ophakathi kwezinto ezahlukene ubuye ungenye yezinto ezibalulekile ezithinta ukusebenza kwemishini. Ngenxa yomehluko ekukhulisweni kwe-thermal kokunwebeka phakathi kwezakhi ze-granite ngokunemba kanye nengxenye ye-ceramic ye-ceramic, lo mehluko udinga ukucatshangelwa ngokugcwele ekwakhiweni nasekukhiqizeni inqubo yokukhiqiza phakathi kwezakhi. Isibonelo, lapho kuhlanganisa ukunemba kwezakhi ze-ceramic ngezensimbi zensimbi, izindlela zokuxhumana ezikhethekile nezinto zokwakha kudingeka ukunciphisa izinkinga zokuhlushwa kanye nezinkinga zokukhubazeka okubangelwa ukwehlukana kokunwebeka.
Uhlelo lokusebenza oluphelele:
Kuzinhlelo zokusebenza ezisebenzayo, izingxenye zokunemba ze-granite kanye nezinto zokunemba ze-ceramic zivame ikhethwe futhi zisetshenziswe ngokwezidingo ezithile. Isibonelo, ezindaweni zokulinganisa ezinembayo, izingxenye zokunemba ze-granite zingasetshenziswa njengezinto zokwakha zomsebenzi kanye nemibhede ukuqinisekisa ukuqina nokunemba kwemishini; Ngasikhathi sinye, ezingxenyeni ezidinga ukunemba okuphezulu kanye nezinguquko ezincane ezibucayi, izinto zokucimana ze-ceramic kungenziwa. Lolu hlelo lokusebenza oluphelele lunganikeza ukudla okugcwele ezinzuzo zezinto zokwakha ezimbili futhi uthuthukise ukusebenza okuphelele kanye nokwethenjwa kwemishini.
Ngamafuphi, umehluko ekubukeni kokunwebeka okushisayo phakathi kwezingxenye zokunemba ama-granite kanye nengxenye ye-ceramic ye-ceramic inomthelela obalulekile ekusetshenzisweni kwemishini enobumba ephezulu. Ngokukhetha okunengqondo nokusetshenziswa kwalezi zinto ezimbili zokwakha, singaqinisekisa ukuthi imishini isengakwazi ukulondolozela ukunemba okuphezulu nokuqina endaweni yokushisa okushintshile, ukuze kuhlangatshezwane nezidingo zemishini ehlukahlukene enokunemba okunembile nokukalwa.
