Njirimara nke graphite gbasaa

① Ike nrụgide nrụgide,mgbanwe, plasticity na mmanu onwe;

② ike iguzogide elu, ala okpomọkụ,corrosionna radieshon;

③ Njirimara seismic siri ike;

④ Ike dị oke egwuconductivity;

⑤Njirimara mgbochi ịka nká na mgbochi mgbagha siri ike.

⑥ Ọ nwere ike iguzogide agbaze na ntinye nke ọla dị iche iche;

⑦ Ọ naghị egbu egbu, enweghị ihe ọ bụla carcinogens na ọ dịghị emerụ gburugburu ebe obibi.

Ọtụtụ ntụziaka mmepe nke graphite gbasaa bụ ndị a:

1. Mgbasa graphite maka ebumnuche pụrụ iche

Nnwale gosiri na ikpuru graphite nwere ọrụ nke ịmịkọrọ ebili mmiri electromagnetic. Grafite gbasaa ga-enwerịrị ihe ndị a chọrọ: (1) obere okpomọkụ mgbasawanye mbụ na nnukwu mgbasawanye; (2) Njirimara kemịkalụ kwụsiri ike, echekwara maka afọ 5, yana mmụba n'ụzọ bụ isi anaghị ere ure; (3) N'elu nke graphite gbasaa na-anọpụ iche na enweghị corrosion na katrij case.

2. Granular gbasaara graphite

Obere urughuru gbasaa graphite na-ezo aka na 300 ntupu na-agbasa graphite nwere mmụba nke 100ml / g. A na-ejikarị ngwaahịa a maka ire ọkụmkpuchi, nke a na-achọsi ike.

3. Mgbasa graphite na elu mmalite mgbasawanye okpomọkụ

Okpomọkụ mgbasawanye nke mbụ nke graphite gbasaa nwere nnukwu okpomoku mgbasawanye mbụ bụ 290-300 ℃, na mmụba olu bụ ≥ 230ml / g. A na-ejikarị ụdị graphite gbasaara nke a maka ire ọkụ nke plastik injinia na rọba.

4. Elu gbanwetụrụ graphite

Mgbe ejiri graphite gbasaa dị ka ihe na-egbochi ire ọkụ, ọ gụnyere ndakọrịta n'etiti graphite na ihe ndị ọzọ. N'ihi nnukwu mineralization nke elu graphite, ọ bụghị lipophilic ma ọ bụ hydrophilic. Ya mere, a ghaghị gbanwee elu nke graphite iji dozie nsogbu nke ndakọrịta n'etiti graphite na ihe ndị ọzọ. A na-atụ aro ka ọ na-achacha elu graphite, ya bụ, iji kpuchie elu graphite na ihe nkiri na-acha ọcha siri ike, nke bụ nsogbu siri ike iji dozie ya. Ọ na-agụnye kemịkalụ membrane ma ọ bụ kemistri elu. Ụlọ nyocha ahụ nwere ike ịme ya, ma enwere ihe isi ike na mmepụta ihe. Ụdị graphite na-acha ọcha na-agbasawanye ka a na-ejikarị dị ka mkpuchi ire ọkụ.

5. Obere okpomọkụ mgbasawanye mbụ na obere okpomọkụ gbasaa graphite

Ụdị graphite gbasaara na-amalite ịgbasa na 80-150 ℃, na mgbasawanye ibu ruru 250ml / g na 600 ℃. Ihe isi ike dị n'ịkwado graphite ịgbasawanye ọnọdụ a bụ: (1) ịhọpụta onye nnọchite mmekọrịta kwesịrị ekwesị; (2) Njikwa na njikwa ọnọdụ ihicha; (3) Mkpebi nke mmiri; (4) Ngwọta nsogbu nchebe gburugburu ebe obibi.
