Abubuwan halayen graphite bearings

Abubuwan halayen graphite bearings

1. Kyakkyawan kwanciyar hankali
Graphite abu ne mai tsayayye na sinadarai, kuma kwanciyar hankalinsa bai kai na karafa masu daraja ba. Solubility a cikin zurfafan azurfa shine kawai 0.001% - 0.002%.Graphiteba a iya narkewa a cikin kwayoyin halitta ko abubuwan kaushi. Ba ya lalacewa da narkewa a yawancin acid, tushe da gishiri.
2. High zafin jiki juriya na graphite hali
Ta hanyar gwaje-gwaje, yawan zafin jiki na sabis na ƙimar ƙimar carbon na gaba ɗaya zai iya kaiwa 350 ℃; Karfe graphite hali kuma 350 ℃; A electrochemical Grafite grade bearing iya isa 450-500 ℃ (a karkashin haske load), ta jiki da kuma inji kaddarorin zama ba canzawa, kuma ta sabis zazzabi iya isa 1000 ℃ karkashin injin ko m yanayi.
3. Kyakkyawar aikin shafa mai
Mai ɗaukar hotoyana da kyakkyawan aikin mai mai da kansa don dalilai biyu. Daya daga cikin dalilan shi ne cewa carbon atoms a cikin graphite lattice an shirya su akan kowane jirgin sama a cikin sifar hexagonal na yau da kullun. Tsakanin atom ɗin yana kusa, wanda ya kai 0.142 nm, yayin da tazarar da ke tsakanin jiragen ya kai 0.335 nm, kuma suna yin tagulla daga juna ta hanya ɗaya. Jirgin na uku yana maimaita matsayin jirgin farko, jirgin na hudu yana maimaita matsayin jirgin na biyu, da sauransu. A cikin kowane jirgin sama, daurin dauri tsakanin carbon atom yana da ƙarfi sosai, yayin da tazarar da ke tsakanin jirage tana da girma, kuma ƙarfin van der Waals a tsakanin su yana da rauni sosai, don haka yana da sauƙin fita da zamewa tsakanin yadudduka, wanda shine ainihin dalilin. dalilin da yasa kayan graphite suna da kaddarorin lubricating.
Dalili na biyu shi ne cewa graphite kayan suna da ƙarfi mannewa tare da mafi karfe kayan, don haka exfoliated graphite iya sauƙi manne da karfe saman a lokacin da nika da karfe, forming Layer na karfe.fim ɗin graphite, wanda ya zama gogayya tsakanin graphite da graphite, don haka da yawa rage lalacewa da gogayya coefficient, Wannan kuma shi ne daya daga cikin dalilan da ya sa carbon graphite bearings da kyau kwarai kai lubricating yi da antifriction yi.
4. Sauran kaddarorin masu ɗaukar hoto
Idan aka kwatanta da sauran bearings,graphite bearingsHar ila yau, suna da high thermal conductivity, low coefficient na mikakke fadada, m sanyaya da zafi juriya da sauransu.
