Hunhu hwemabheyaringi egraphite

Hunhu hwemabheyaringi egraphite

1. Kugadzikana kwakanaka kwemakemikari
Graphite chinhu chinogara kwenguva refu mumakemikari, uye kugadzikana kwayo mumakemikari hakuna kuderera pane kwesimbi dzinokosha. Kunyunguduka kwayo musirivha yakanyungudutswa kunongova 0.001% - 0.002%.GrafitiHainyungudike muzvinhu zvinonyungudutsa zve organic kana inorganic. Hainyungudike kana kunyungudika mu acids, bases nemunyu zvakawanda.
2. Kudzivirira kupisa kwakanyanya kwekubata graphite
Kuburikidza nekuyedza, tembiricha yebasa remabheyaringi emhando yekabhoni inogona kusvika 350 ℃; simbi graphite bearing iriwo 350 ℃; Electrochemical graphite grade bearing inogona kusvika 450-500 ℃ (pasi pemutoro wakareruka), hunhu hwayo hwepanyama uye hwemakanika hunoramba husina kuchinja, uye tembiricha yebasa inogona kusvika 1000 ℃ pasi pemhepo inotonhorera kana inodzivirira.
3. Kushanda zvakanaka kwekuzvizora mafuta
Graphite bearingine simba rakanaka rekuzvizora nekuda kwezvikonzero zviviri. Chimwe chezvikonzero ndechekuti maatomu ekabhoni ari mu graphite lattice akarongwa pane imwe neimwe ndege muchimiro chehexagonal chakajairika. Daro riri pakati pemaatomu riri pedyo, rinova 0.142 nm, nepo daro riri pakati pendege riri 0.335 nm, uye akatsauswa kubva kune mumwe nemumwe munzira imwe chete. Ndege yechitatu inodzokorora nzvimbo yendege yekutanga, ndege yechina inodzokorora nzvimbo yendege yechipiri, zvichingodaro. Mundege yega yega, simba rekubatanidza pakati pemaatomu ekabhoni rakasimba kwazvo, nepo daro riri pakati pendege rakakura, uye simba revan der Waals riri pakati pawo risina simba, saka zviri nyore kusiya nekutsvedza pakati pezvikamu, ndicho chikonzero chikuru nei zvinhu zve graphite zvine hunhu hwekuzvizora.
Chikonzero chechipiri ndechekuti zvinhu zvegrafiti zvinonamatira zvakasimba pazvinhu zvakawanda zvesimbi, saka girafiti yakabviswa inogona kunamira zviri nyore pamusoro pesimbi painokuya nesimbi, zvichiita kuti pave nechikamu chefirimu regirafiti, iyo inova kukweshana pakati pegraphite negraphite, nokudaro ichideredza zvakanyanya kupfeka uye friction coefficient. Ichi ndicho chimwe chezvikonzero nei mabheringi ecarbon graphite ane kugona kwakanaka kwekuzvizora uye kugona kudzivirira kukweshana.
4. Zvimwe zvinhu zve graphite bearing
Zvichienzaniswa nemamwe mabheyaringi,mabheyaringi egirafitiinewo thermal conductivity yakanyanya, linear expansion yakaderera, inotonhorera nekukurumidza uye inodzivirira kupisa nezvimwewo.
