Katundu wa ma graphite bearing

Katundu wa ma graphite bearing

1. Kukhazikika kwabwino kwa mankhwala
Graphite ndi chinthu chokhazikika pa mankhwala, ndipo kukhazikika kwa mankhwala ake sikotsika poyerekeza ndi kwa zitsulo zamtengo wapatali. Kusungunuka kwake mu siliva wosungunuka ndi 0.001% - 0.002% yokha.GraphiteSisungunuka mu zinthu zachilengedwe kapena zopanda chilengedwe. Sizimawononga ndi kusungunuka mu ma acid ambiri, ma base ndi mchere.
2. Kukana kutentha kwambiri kwa graphite
Kudzera mu zoyeserera, kutentha kwa ntchito ya ma bearing a carbon grade general kumatha kufika 350 ℃; Kubearing kwa graphite yachitsulo ndi 350 ℃; Kubearing kwa graphite yamagetsi kumatha kufika 450-500 ℃ (pansi pa katundu wopepuka), mawonekedwe ake akuthupi ndi amakina sakhala osasinthika, ndipo kutentha kwake kwa ntchito kumatha kufika 1000 ℃ pansi pa vacuum kapena mlengalenga woteteza.
3. Kugwira ntchito bwino kodzipaka mafuta
Kutengera kwa graphiteIli ndi mphamvu yabwino yodzipaka mafuta pazifukwa ziwiri. Chimodzi mwa zifukwa zake ndichakuti maatomu a kaboni omwe ali mu graphite lattice amakonzedwa pa ndege iliyonse mu mawonekedwe ofanana a hexagonal. Mtunda pakati pa maatomu uli pafupi, womwe ndi 0.142 nm, pomwe mtunda pakati pa ndege ndi 0.335 nm, ndipo amasinthasintha kuchokera kwa wina ndi mnzake mbali imodzi. Ndege yachitatu imabwereza malo a ndege yoyamba, ndege yachinayi imabwereza malo a ndege yachiwiri, ndi zina zotero. Mu ndege iliyonse, mphamvu yomangirira pakati pa maatomu a kaboni ndi yamphamvu kwambiri, pomwe mtunda pakati pa ndege ndi waukulu, ndipo mphamvu ya van der Waals pakati pawo ndi yofooka kwambiri, kotero ndikosavuta kuchoka ndikutsetsereka pakati pa zigawo, chomwe ndi chifukwa chachikulu chomwe zida za graphite zili ndi mphamvu zodzipaka mafuta.
Chifukwa chachiwiri n’chakuti zinthu za graphite zimamatira kwambiri ku zinthu zambiri zachitsulo, kotero graphite yochotsedwa imatha kumamatira mosavuta pamwamba pa chitsulo ikapera ndi chitsulo, ndikupanga wosanjikiza wafilimu ya graphite, zomwe zimakhala kukangana pakati pa graphite ndi graphite, motero zimachepetsa kwambiri kutopa ndi kupsinjika kwa coefficient. Ichi ndi chimodzi mwa zifukwa zomwe ma bearing a carbon graphite ali ndi magwiridwe antchito abwino kwambiri odzipaka mafuta komanso magwiridwe antchito oletsa kukangana.
4. Zina mwa zinthu zomwe zimapanga graphite
Poyerekeza ndi ma bearing ena,mabearing a graphiteali ndi kutentha kwakukulu, kufalikira kochepa kwa mzere, kuzizira mwachangu komanso kukana kutentha ndi zina zotero.
