Graphite chinhu chakasarudzika uye chakasarudzika chine zvinhu zvinoshamisa zvekupisa. Thermal conductivity yegraphite inowedzera nekuwedzera kwekushisa, uye kupisa kwayo kunogona kusvika 1500-2000 W / (mK) pane tembiricha yekamuri, iyo inenge ka5 yemhangura uye kanopfuura ka10 iyo yesimbi aruminiyamu.
Thermal conductivity zvinoreva kugona kwechinhu kuitisa kupisa.Inopimwa tichitarisa kuti kupisa kunogona kukurumidza sei kufamba muchinhu.Graphite, chimiro chinongoitika chekabhoni, ine imwe yepamusoro-soro conductivities pakati pezvinhu zvese zvinozivikanwa.Iyo inoratidza yakasarudzika yekupisa conductivity munzira inotenderera kune yayo maseru, ichiita iyo yakanakira zvinhu zvekushandisa kwakawanda.
Graphite chimiroine zvidimbu zvemaatomu ecarbon akarongwa mune hexagonal lattice.Mukati mechikamu chimwe nechimwe, maatomu ecarbon anobatwa pamwechete nema bond akasimba akasimba.Nekudaro, zvisungo zviri pakati pezvikamu, zvinozivikanwa seVan der Waals mauto, hazvina kusimba.Ndiko kurongeka kwekabhoni maatomu mukati mezvikamu izvi izvo zvinopa graphite yakasarudzika yekupisa yekupisa maitiro.
Iyo yekupisa conductivity yegraphite inonyanya kukonzerwa neiyo yakakwira kabhoni yemukati uye yakasarudzika crystal chimiro.Iyo carbon-carbon bonds mukati mechikamu chimwe nechimwe inobvumira kupisa kuendesa nyore nyore mundege yedanda.Kubva kune Kubva kumakemikari formular ye graphite, tinogona kunzwisisa simba risina simba re-inter-layer rinoita kuti zvikwanisike kuti phonon (vibrational energy) ifambe nokukurumidza. neparutanda.
Iyo yakakwirira yekupisa conductivity yegraphite yakakonzera kushandiswa kwayo kwakanyanya mumaindasitiri akasiyana.
Ini: Kugadzira graphite electrode.
Graphite chimwe chezvinhu zvakakosha zvekugadzira graphite electrode, iyo ine mabhenefiti ekukwirira kwekushisa kwekushisa, kupisa kwekushisa kwepamusoro, kugadzikana kwakanaka kwemakemikari, kusimba kwemagetsi, saka inoshandiswa zvakanyanya musimbi, indasitiri yemakemikari, simba remagetsi uye mamwe maindasitiri mune electrolytic uye yemagetsi muchoto process.
II: Graphite inoshandiswa mumunda wemagetsi.
Graphite inoshandiswa sechinhu chinopisa chekupisa kuti chiparadze kupisa kunogadzirwa nemagetsi emagetsi senge transistors, integrated circuits, uye magetsi modules.Kukwanisa kwayo kuendesa kupisa kubva kune izvi zvishandiso kunobatsira kuchengetedza kugadzikana uye kudzivirira kupisa.
III: graphite inoshandiswa mukugadzirwa kwecruciblesnezviumbwa zvesimbi.
Yayo yakakwirira yekupisa conductivity inobvumira kufambisa kupisa kwakanaka, kuve nechokwadi chekudziya kweyunifomu uye kutonhora kwesimbi.Izvi, zvakare, zvinovandudza kunaka uye kuwirirana kwechigadzirwa chekupedzisira.
IV: Graphite thermal conductivity inoshandiswa muindasitiri yemuchadenga.
Graphite macomposites anoshandiswa mukuvaka kwendege uye zvinhu zvemuchadenga.Iyo yakasarudzika yekupisa yekupisa zvimiro zvegraphite inobatsira mukugadzirisa tembiricha yakanyanyisa inowanikwa panguva yekushanya kwechadenga uye nendege dzinomhanya.
V: Graphite inoshandiswa semafuta mumaindasitiri akasiyana siyana.
Inowanzo shandiswa mukugadzira maitiro uko kupisa kwakanyanya uye kumanikidza kunobatanidzwa, senge injini dzemotokari uye michina yesimbi.Iko kugona kwegraphite kumira tembiricha yakakwira uku ichidzikisa kukweshera kunoita kuti ive yakanakira lubricant yezvishandiso zvakadaro.
VI: Graphite inoshandiswa mukutsvaga kwesainzi.
Inowanzo shandiswa sechinhu chakajairwa chekuyera kupisa kwemafuta ezvimwe zvinhu.Iyo yakanyatsogadziriswa thermal conductivity values ye graphite inoshanda sechinhu chinotaridzirwa chekuenzanisa uye kuongorora maitiro ekupisa kwekushisa kwezvinhu zvakasiyana-siyana.
Mukupedzisa, graphite thermal conductivity yakasarudzika nekuda kweiyo yakasarudzika crystal chimiro uye yakakwira kabhoni yemukati.Kugona kwayo kufambisa kupisa zvakanaka kwaita kuti ive yakakosha mumaindasitiri akasiyana siyana, kusanganisira zvemagetsi, simbi yekukanda, aerospace, uye lubrication.Uyezve, graphite inoshanda sechiyereso chekuyeresa kudziya kwekupisa kwezvimwe zvinhu.Nekunzwisisa uye kushandisa zvakasarudzikazvinhu zvegraphite, tinogona kuenderera mberi nekuongorora zvikumbiro zvitsva uye kufambira mberi mumunda wekupisa kupisa uye kutonga kwekushisa.
