Kedu ihe bụ njirimara mara mma nke graphite gbasaa

1, Mechanical ọrụ:
1.1Nnukwu mkpakọ na resilience: maka ngwaahịa graphite gbasaa, a ka nwere ọtụtụ oghere oghere mechiri emechi nke nwere ike ịgbatị n'okpuru ọrụ nke ike mpụga. N'otu oge ahụ, ha nwere nkwụghachi n'ihi esemokwu nke ikuku na obere oghere oghere.
1.2Mgbanwe: isi ike dị nnọọ ala. Enwere ike iji ngwá ọrụ nkịtị bee ya, ma nwee ike merụọ ahụ ma gbadaa n'aka aka ike;
2. Ọrụ anụ ahụ na kemịkal:
2.1 Ịdị ọcha: ọdịnaya carbon nke edobere bụ ihe dịka 98%, ma ọ bụ karịa 99%, nke zuru ezu iji gboo ihe achọrọ.elu-ọchaakara na ike na ụlọ ọrụ ndị ọzọ;
2. Njupụta: nannukwu njupụtanke graphite flake bụ 1.08g/cm3, nnukwu njupụta nke graphite gbasaa bụ 0.002 ~ 0.005g/cm3, na njupụta ngwaahịa bụ 0.8 ~ 1.8g/cm3. Ya mere, ihe graphite gbasaa bụ ìhè na plastik;
3. Nguzogide okpomọkụ: usoro iwu, na gbasaa graphite nwere ike idi - 200 ℃ ka 3000 ℃. Dị ka akara nkwakọ ngwaahịa, enwere ike iji ya mee ihe n'enweghị nsogbu na - 200 ℃ ~ 800 ℃. Ọ nwere ọrụ magburu onwe ya nke enweghị mgbatị, ọ dịghị ịka nká na obere okpomọkụ, ọ dịghị nro, ọ dịghị nrụrụ na ọ dịghị ire ere na elu okpomọkụ;
4. Nguzogide corrosion: o nwere ume umengwụ. Na mgbakwunye na ụfọdụ okpomọkụ kpọmkwem nke oxidants siri ike dị ka aqua regia, nitric acid, sulfuric acid na halogen, enwere ike iji ya na ọtụtụ mgbasa ozi dị ka acid, alkali, nnu ngwọta, mmiri mmiri, uzuoku na organic mgbaze;
5. Ezigbo thermal conductivityna obere ọnụọgụ mgbasawanye thermal. Akụkụ ya dị nso n'otu usoro nke ịdị ukwuu nke data akụkụ abụọ nke akụrụngwa akara izugbe. Enwere ike mechie ya nke ọma n'okpuru ọnọdụ ọrụ nke okpomọkụ dị elu, cryogenic na mgbanwe okpomọkụ dị nkọ;
6. Ihe mgbochi radieshone: dabere na ụzarị neutron γ Ray α Ray β X-ray irradiation ruo ogologo oge na-enweghị mgbanwe doro anya;
7. Impermeability: ezigbo impermeability na gas na mmiri mmiri. N'ihi nnukwu ike elu nke graphite gbasaa, ọ dị mfe ịmepụta ihe nkiri gas dị oke mkpa ma ọ bụ ihe nkiri mmiri mmiri iji gbochie ntinye nke ọkara;
8. Mmanya onwe: graphite gbasaara ka na-edobe ihe owuwu hexagonal ụgbọelu. N'okpuru omume nke mpụga ike, ụgbọelu n'ígwé dị mfe slide dịtụ na onwe lubrication emee, nke nwere ike n'ụzọ dị irè gbochie iyi nke aro ma ọ bụ valvụ mkpanaka.
