Njirimara nke bearings graphite

Njirimara nke bearings graphite

1. Ezigbo nkwụsi ike kemịkalụ
Graphite bụ ihe na-adịgide adịgide na kemịkalụ, ọ dịghịkwa ka ọ dị ala karịa nke ọla dị oké ọnụ ahịa. Ọ na-agbaze naanị site na ọlaọcha a gbazere agbaze bụ 0.001% – 0.002%.Grafitọ naghị agbaze na ihe mgbaze organic ma ọ bụ nke na-adịghị agbaze. Ọ naghị agbaze ma ọ bụ gbazee n'ọtụtụ asịd, ntọala na nnu.
2. Oke okpomọkụ nke graphite bearing
Site na nnwale, okpomọkụ ọrụ nke bearings ọkwa carbon izugbe nwere ike iru 350 ℃; Bearings graphite ọla dịkwa 350 ℃; Bearings ọkwa graphite electrochemical nwere ike iru 450-500 ℃ (n'okpuru ibu dị mfe), ihe onwunwe anụ ahụ na nke mekaniki ya anaghị agbanwe agbanwe, okpomọkụ ọrụ ya nwekwara ike iru 1000 ℃ n'okpuru ikuku ikuku ma ọ bụ ikuku nchebe.
3. Ezigbo arụmọrụ na-eme ka mmanụ dị mma
Graphite na-ebu ihenwere ezigbo ọrụ nke na-eme ka mmanụ dị n'onwe ya maka ihe abụọ. Otu n'ime ihe kpatara ya bụ na atọm carbon dị na lattice graphite dị n'elu plane ọ bụla n'ụdị hexagonal nkịtị. Anya dị n'etiti atọm dị nso, nke bụ 0.142 nm, ebe anya dị n'etiti plane bụ 0.335 nm, ha na-agbagọkwa n'otu ụzọ. Plane nke atọ na-emegharị ọnọdụ nke plane nke mbụ, plane nke anọ na-emegharị ọnọdụ nke plane nke abụọ, wdg. N'elu plane ọ bụla, ike njikọ dị n'etiti atọm carbon siri ike nke ukwuu, ebe anya dị n'etiti plane buru ibu, ike van der Waals dị n'etiti ha adịghịkwa ike nke ukwuu, yabụ ọ dị mfe ịpụ ma mikpuo n'etiti oyi akwa, nke bụ isi ihe kpatara ihe graphite ji nwee ihe ndị na-eme ka mmanụ dị n'onwe ha.
Ihe nke abụọ kpatara ya bụ na ihe ndị e ji graphite mee nwere ike ịrapara n'ọtụtụ ihe e ji ígwè rụọ, ya mere graphite e ji ígwè rụọ nwere ike ịrapara n'elu ígwè ahụ ngwa ngwa mgbe e ji ígwè gwerie ya, wee mepụta oyi akwa nkeihe nkiri graphite, nke na-aghọ esemokwu dị n'etiti graphite na graphite, si otú a na-ebelata oke iyi na oke esemokwu. Nke a bụkwa otu n'ime ihe kpatara bearings carbon graphite ji nwee arụmọrụ magburu onwe ya na arụmọrụ mgbochi esemokwu.
4. Njirimara ndị ọzọ nke graphite bearing
Ma e jiri ya tụnyere ndị ọzọ bearings,graphite bearingsnwekwara ike ime ka okpomọkụ dị elu, obere ihe gbasara mgbasawanye linear, oyi ngwa ngwa na iguzogide okpomọkụ na ihe ndị ọzọ.
