Yiziphi izici ezinhle kakhulu ze-graphite enwetshiwe

1. Umsebenzi wemishini:
1.1Ukucindezelwa okuphezulu nokuqina: emikhiqizweni enwetshiwe ye-graphite, kusenezikhala ezincane ezivaliwe eziningi ezingaqiniswa ngaphansi kwesenzo samandla angaphandle. Ngesikhathi esifanayo, banokusimama ngenxa yokushuba komoya ezindaweni ezincane ezivulekile.
1.2Ukuvumelana nezimo: ubulukhuni buphansi kakhulu. Ingasikwa ngamathuluzi ajwayelekile, futhi ingalimala futhi igotshwe ngokungafanele;
2. Imisebenzi engokomzimba neyamakhemikhali:
2.1 Ubumsulwa: Ikhabhoni engaguquki icishe ibe ngama-98%, noma ngaphezulu kwama-99%, eyanele ukuhlangabezana nezidingo zeubumsulwa obuphezuluizimpawu zamandla nakweminye imboni;
2. Ukuminyana: theukuminyana ngobuningiye-flake graphite ngu-1.08g/cm3, ukuminyana kwenqwaba yegraphite enwetshiwe ngu-0.002 ~ 0.005g/cm3, futhi ukuminyana komkhiqizo ngu-0.8 ~ 1.8g/cm3. Ngakho-ke, impahla ye-graphite eyandisiwe ilula futhi ipulasitiki;
3. Ukumelana nezinga lokushisa: ngokwethiyori, i-graphite enwetshiwe ingamelana - 200 ℃ kuya ku-3000 ℃. Njengophawu lokupakisha, lungasetshenziswa ngokuphepha ku-200 ℃ ~ 800 ℃. Inemisebenzi emihle kakhulu yokungabikho kwe-embrittlement, akukho ukuguga ekushiseni okuphansi, akukho ukuthambisa, akukho ukuguquguquka nokubola ekushiseni okuphezulu;
4. Ukumelana nokugqwala: inobuvila bamakhemikhali. Ngaphezu kwamazinga athile okushisa athile ama-oxidants aqinile njenge-aqua regia, i-nitric acid, i-sulfuric acid ne-halogen, ingasetshenziswa emithonjeni eminingi efana ne-asidi, i-alkali, isixazululo sikasawoti, amanzi olwandle, umusi kanye ne-organic solvent;
5. I-conductivity enhle kakhulu ye-thermalkanye ne-coefficient encane yokwandisa ukushisa. Imingcele yayo iseduze ne-oda elifanayo lobukhulu bedatha yezingxenye ezimbili zemishini yokuvala evamile. Ingase futhi ivalwe kahle ngaphansi kwezimo zokusebenza zokushisa okuphezulu, ukuguquka kwe-cryogenic kanye nokushisa okubukhali;
6. I-radiation resistance: ngaphansi kwemisebe ye-neutron γ Ray α Ray β X-ray irradiation isikhathi eside ngaphandle koshintsho olusobala;
7. Ukungangenisi: ukungangeni kahle kwegesi noketshezi. Ngenxa yamandla amakhulu e-graphite eyandisiwe, kulula ukwenza ifilimu yegesi encane kakhulu noma ifilimu ewuketshezi ukuvimbela ukungena okuphakathi;
8. Ukuzithambisa: i-graphite enwetshiwe isagcina isakhiwo esinezingqimba zendiza ene-hexagonal. Ngaphansi kwesenzo samandla angaphandle, izingqimba zendiza kulula ukushelela kancane futhi ukuzigcoba ngokwakho kwenzeka, okungavimbela ngempumelelo ukuguga kwe-shaft noma i-valve rod.
