Njirimara nke graphite bearings

Njirimara nke graphite bearings

1. Ezigbo nkwụsi ike nke kemịkal
Graphite bụ ihe kwụsiri ike na kemịkal, nkwụsi ike kemịkal ya adịghịkwa ala karịa nke ọla dị oke ọnụ ahịa. Solubility ya na ọlaọcha a wụrụ awụ bụ naanị 0.001% - 0.002%.Graphitebụ insoluble ke organic ma ọ bụ inorganic solvents. Ọ naghị emebi ma gbarie n'ọtụtụ acid, bases na salts.
2. Nnukwu okpomọkụ na-eguzogide nke graphite
Site nnwale, ọrụ okpomọkụ nke izugbe carbon ọkwa bearings nwere ike iru 350 ℃; Igwe graphite metal bụkwa 350 ℃; The electrochemical graphite ọkwa ibu nwere ike iru 450-500 ℃ (n'okpuru ìhè ibu), ya anụ ahụ na n'ibu Njirimara na-agbanweghi agbanwe, na ya ọrụ okpomọkụ nwere ike iru 1000 ℃ n'okpuru agụụ ma ọ bụ nchebe ikuku.
3. Ọmarịcha mma mmanye onwe ya
Ihe ngosi eseresenwere ezigbo ọrụ mmanye onwe ya maka ihe abụọ. Otu n'ime ihe kpatara ya bụ na a na-ahazi carbon carbon dị na lattice graphite n'ụgbọelu ọ bụla n'ụdị hexagonal mgbe niile. Ebe dị anya n'etiti atom dị nso, nke bụ 0.142 nm, ebe anya n'etiti ụgbọ elu bụ 0.335 nm, ha na-esikwa n'otu ụzọ ahụ na-atụgharị. Ụgbọ elu nke atọ na-emegharị ọnọdụ nke ụgbọ elu mbụ, ụgbọ elu nke anọ na-emegharị ọnọdụ nke ụgbọ elu nke abụọ, na ihe ndị ọzọ. N'ime ụgbọ elu ọ bụla, ike na-ejikọta n'etiti carbon carbon dị nnọọ ike, ebe ebe dị anya n'etiti ụgbọ elu dị ukwuu, na ike van der Waals dị n'etiti ha adịghị ike, ya mere ọ dị mfe ịhapụ na slide n'etiti ọkwa, nke bụ isi ihe kpatara ya. ihe mere ihe graphite ji nwee ihe na-eme mmanụ onwe ya.
Nke abụọ kpatara ya bụ na graphite ihe nwere ike adhesion na ọtụtụ metal ihe, otú exfoliated graphite nwere ike mfe na-arapara n'elu metal elu mgbe egweri na metal, na-akpụ a oyi akwa nke.ihe nkiri graphite, nke na-aghọ esemokwu dị n'etiti graphite na graphite, si otú a na-ebelata ịdị arọ na ọnụ ọgụgụ esemokwu, Nke a bụkwa otu n'ime ihe kpatara carbon graphite bearings ji enwe ezigbo mmanye onwe ya na arụmọrụ mgbochi.
4. Njirimara ndị ọzọ nke ibu graphite
E jiri ya tụnyere ndị ọzọ bearings,graphite bearingsnwekwara nnukwu okpomọkụ conductivity, obere ọnụọgụ nke mgbasawanye linear, ngwa ngwa jụrụ oyi na nguzogide okpomọkụ na ihe ndị ọzọ.
