Kayayyakin bearings na graphite

Kayayyakin bearings na graphite

1. Kyakkyawan daidaiton sinadarai
Graphite abu ne mai karko a fannin sinadarai, kuma daidaiton sinadaransa bai gaza na karafa masu daraja ba. Narkewarsa a cikin azurfa mai narkewa bai wuce kashi 0.001% – 0.002% kawai ba.Graphiteba ya narkewa a cikin sinadarai masu narkewa na halitta ko marasa tsari. Ba ya narkewa ko narkewa a cikin yawancin acid, tushe da gishiri.
2. Juriyar zafin jiki mai yawa na ɗaukar nauyin graphite
Ta hanyar gwaje-gwaje, zafin sabis na bearings na carbon gabaɗaya zai iya kaiwa 350 ℃; Bearings na ƙarfe graphite kuma yana da 350 ℃; Bearings na electrochemical graphite na iya kaiwa 450-500 ℃ (a ƙarƙashin nauyi mai sauƙi), halayensa na zahiri da na injiniya ba su canzawa ba, kuma zafin sabis ɗinsa na iya kaiwa 1000 ℃ a ƙarƙashin injin ko yanayi mai kariya.
3. Kyakkyawan aikin shafawa mai kyau
graphite bearingyana da kyakkyawan aikin shafawa mai kauri saboda dalilai biyu. Ɗaya daga cikin dalilan shine cewa ƙwayoyin carbon da ke cikin layin graphite an shirya su akan kowane jirgi a cikin siffar hexagonal na yau da kullun. Nisa tsakanin ƙwayoyin suna kusa, wanda shine 0.142 nm, yayin da nisan da ke tsakanin jiragen shine 0.335 nm, kuma suna karkata daga juna a hanya ɗaya. Jirgin sama na uku yana maimaita matsayin jirgin farko, jirgin sama na huɗu yana maimaita matsayin jirgin sama na biyu, da sauransu. A kowane jirgi, ƙarfin ɗaure tsakanin ƙwayoyin carbon yana da ƙarfi sosai, yayin da nisan da ke tsakanin jiragen sama yana da girma, kuma ƙarfin van der Waals da ke tsakaninsu yana da rauni sosai, don haka yana da sauƙin barinwa da zamewa tsakanin layuka, wanda shine babban dalilin da yasa kayan graphite ke da kaddarorin shafawa mai kauri.
Dalili na biyu shi ne cewa kayan graphite suna da mannewa mai ƙarfi tare da yawancin kayan ƙarfe, don haka graphite ɗin da aka cire zai iya mannewa da saman ƙarfe cikin sauƙi lokacin niƙa da ƙarfe, yana samar da Layer nafim ɗin graphite, wanda ya zama gogayya tsakanin graphite da graphite, don haka yana rage yawan lalacewa da gogayya sosai, Wannan kuma yana ɗaya daga cikin dalilan da yasa bearings na carbon graphite suke da kyakkyawan aikin shafawa da kuma aikin hana gogayya.
4. Sauran kaddarorin graphite bearing
Idan aka kwatanta da sauran bearings,bearings na graphitekuma suna da babban ƙarfin lantarki na thermal, ƙarancin yawan faɗaɗa layi, saurin sanyaya da juriya ga zafi da sauransu.
