Kana flake graphite ichikwizwa nesimbi, firimu rakatetepa regraphite rinoumbwa pamusoro pesimbi uye flake graphite, uye ukobvu hwaro uye kutaridzika kwaro kunosvika kune imwe kukosha, ndiko kuti, iyo flake graphite inopfeka nekukurumidza pakutanga, uye yobva yadonha kusvika isingachinji. value. Iyo yakachena simbi graphite friction surface ine zvirinani kutaridzika, madiki ekristaro firimu ukobvu uye yakakura adhesion. Iyi friction surface inogona kuve nechokwadi chekuti chiyero chekupfeka uye friction data idiki pakupera kwekupokana. Iyo inotevera mupepeti weFuruite Graphite inokutora iwe kuti uongorore kupfeka kuramba zvinhu zveflake graphite:
Graphite ine high thermal conductivity, iyo inobatsira kuendesa kupisa nekukurumidza kubva kune friction pamusoro, kuitira kuti tembiricha mukati mechinhu uye friction surface inogona kuenzana. Kana dzvinyiriro ikaramba ichiwedzera, oriented graphite film ichakuvadzwa zvakanyanya, uye chiyero chekupfeka uye friction coefficient ichawedzerawo nekukurumidza. Kune akasiyana graphite metal friction surfaces, muzviitiko zvese, iyo yakakwirira inotenderwa kudzvanywa, zviri nani kutaridzika kwefirimu regirafu rakaumbwa panzvimbo yekukwesha. Mukati memhepo ine tembiricha ye300 ~ 400 ℃, dzimwe nguva friction coefficient inowedzerwa nekuda kweiyo oxidation yakasimba yeflake graphite.
Kudzidzira kunoratidza kuti flake graphite inonyanya kubatsira mukusarerekera kana kuderedza midhiya ine tembiricha ye300 ~ 1000 ℃. Graphite inodzivirira kupfeka zvinhu zvakamisikidzwa nesimbi kana resin inokodzera kushanda mugasi kana mvura yepakati ine humidity ye100%, asi iyo tembiricha yekushanda kwayo inodzivirirwa nekupikiswa kwekupisa kweresin uye nzvimbo yekunyungudika kwesimbi.
