Yiziphi izakhiwo ezinhle kakhulu ze-graphite enwetshiwe

1, Umsebenzi womshini:
1.1Ukucindezelwa okuphezulu nokuqina: ngemikhiqizo ye-graphite enwetshiwe, kusenezindawo eziningi ezivulekile ezincane ezivaliwe ezingaqiniswa ngaphansi kwesenzo samandla angaphandle. Ngesikhathi esifanayo, zinamandla okuqina ngenxa yokucindezeleka komoya ezindaweni ezincane ezivulekile.
1.2Ukuzivumelanisa nezimo: ubulukhuni buphansi kakhulu. Ingasikwa ngamathuluzi ajwayelekile, futhi ingalimala futhi igotshwe ngokungahleliwe;
2, Imisebenzi yomzimba kanye namakhemikhali:
2.1 Ubumsulwa: okuqukethwe kwekhabhoni okungaguquki kungaba ngu-98%, noma ngisho nangaphezu kuka-99%, okwanele ukuhlangabezana nezidingo zeubumsulwa obuphezuluizivalo kwezamandla nakweminye imboni;
2. Ubuningi:ukuminyana kwenqwabai-graphite enwetshiwe ingu-1.08g/cm3, ubukhulu be-graphite enwetshiwe bungu-0.002 ~ 0.005g/cm3, kanti ubukhulu bomkhiqizo bungu-0.8 ~ 1.8g/cm3. Ngakho-ke, izinto ze-graphite enwetshiwe zilula futhi zipulasitiki;
3. Ukumelana nokushisa: ngokwethiyori, i-graphite enwetshiwe ingamelana nokushisa okungu-200 ℃ kuya ku-3000 ℃. Njengesivalo sokupakisha, ingasetshenziswa ngokuphephile ku-200 ℃ ~ 800 ℃. Inemisebenzi emihle kakhulu yokungagugi, ukuguga ekushiseni okuphansi, ukuthambisa, ukuguquguquka kanye nokubola ekushiseni okuphezulu;
4. Ukumelana nokugqwala: inobuvila bamakhemikhali. Ngaphezu kwamazinga okushisa athile ama-oxidant aqinile njenge-aqua regia, i-nitric acid, i-sulfuric acid kanye ne-halogen, ingasetshenziswa ezintweni eziningi ezifana ne-asidi, i-alkali, isixazululo sikasawoti, amanzi olwandle, umusi kanye ne-organic solvent;
5. Ukuqhuba kahle kokushisakanye ne-coefficient encane yokwandisa ukushisa. Amapharamitha ayo asondele ku-oda elifanayo lobukhulu bedatha yezingxenye ezimbili zemishini yokuvala ejwayelekile. Ingaphinde ivalwe kahle ngaphansi kwezimo zokusebenza zokushisa okuphezulu, ukushintsha kwezinga lokushisa okubukhali kanye nokushisa okubukhali;
6. Ukumelana nemisebee: ingaphansi kwemisebe ye-neutron γ Ray α Ray β ukushiswa kwemisebe ye-X isikhathi eside ngaphandle koshintsho olusobala;
7. Ukungangenwa: ukungangenwa kahle kwegesi kanye noketshezi. Ngenxa yamandla amakhulu ebusweni be-graphite enwetshiwe, kulula ukwakha ifilimu yegesi encane kakhulu noma ifilimu yoketshezi ukuvimbela ukungena okuphakathi;
8. Ukuzigcoba ngokwakho: i-graphite enwetshiwe isagcina isakhiwo esinezingqimba zendiza ezinezinhlangothi eziyisithupha. Ngaphansi kwesenzo samandla angaphandle, izingqimba zendiza kulula ukuzishelela ngokulinganisela futhi kwenzeka ukuzithambisa, okungavimbela ngempumelelo ukuguguleka kwenduku yomgodi noma yevalvu.
