Zvinhu zve graphite bearings

Zvinhu zve graphite bearings

1. Kugadzikana kwakanaka kwemakemikari
Graphite ikemikari yakagadzikana zvinhu, uye kugadzikana kwayo kwemakemikari hakusi pasi peiyo yesimbi inokosha. Kunyungudika kwayo musirivheri yakanyungudutswa inongova 0.001% - 0.002%.Graphiteisinganyunguriki muorganic kana inorganic solvents. Iyo haina kuora uye inonyungudika mune akawanda acids, mabhesi uye munyu.
2. Kunyanya kupisa kwekushisa kwegirafu inotakura
Kuburikidza nemiedzo, tembiricha yebasa ye general carbon grade bearings inogona kusvika 350 ℃; Metal graphite kubereka zvakare 350 ℃; Iyo electrochemical graphite giredhi inotakura inogona kusvika 450-500 ℃ (pasi peyakaremerwa mutoro), yayo yemuviri uye michina zvimiro zvinoramba zvisingachinji, uye tembiricha yayo yebasa inogona kusvika 1000 ℃ pasi pevacuum kana inodzivirira mamiriro.
3. Yakanaka yekuzvizora kuita
Graphite kuberekaine yakanaka yekuzvizora kuita nekuda kwezvikonzero zviviri. Chimwe chezvikonzero ndechekuti maatomu ekabhoni ari mugiredhi rendiro akarongwa pandege yega yega nenzira yenguva dzose ine hexagonal shape. Chinhambwe chiri pakati pemaatomu chiri padyo, chinova 0.142 nm, nepo chinhambwe chiri pakati pendege chiri 0.335 nm, uye dzakadzedzereka dzichibva kune imwe neimwe munzira imwechete. Ndege yechitatu inodzokorora nzvimbo ye ndege yekutanga, ndege yechina inodzokorora nzvimbo yechipiri ndege, zvichingodaro. Mundege imwe neimwe, simba rinosunga pakati peatomu kabhoni rakasimba kwazvo, nepo chinhambwe chiri pakati pendege chakakura, uye van der Waals simba riri pakati padzo harina kusimba, saka zviri nyore kusiya nekutsvedza pakati pezvikamu, ndicho chikonzero chakakosha. nei graphite zvinhu zvine self-lubricating properties.
Chikonzero chechipiri ndechekuti girafu zvinhu zvine kunamatira kwakasimba nemidziyo yakawanda yesimbi, saka iyo exfoliated graphite inogona kunamatira nyore kune pamusoro pesimbi kana ichikuya nesimbi, ichigadzira layer yesimbi.graphite film, iyo inova kupesana pakati pe graphite ne graphite, nokudaro kuderedza zvakanyanya kupfeka uye friction coefficient, Ichi zvakare chimwe chezvikonzero nei carbon graphite bearings ine yakanakisa self-lubricating performance uye antifriction performance.
4. Zvimwe zvinhu zvekubereka graphite
Kuenzaniswa nemamwe mabhengi,graphite bearingszvakare ine yakakwirira yekupisa conductivity, yakaderera coefficient yekuwedzera kwemutsara, kukurumidza kutonhora uye kupisa kuramba uye zvichingodaro.
