Zvinhu zveGraphite zvinodziya, semidziyo yekudziisa inopisa zvakanyanya, inoshandiswa zvakanyanya mumaindasitiri mazhinji, anosanganisira simbi, zvemagetsi, semiconductors, uye makemikari. Zvinhu zveGraphite zvine mafambiro akanaka ekupisa, zvinodzivirira kupisa zvakanyanya, uye kugadzikana kwemakemikari, zvichivabvumira kuchengetedza kushanda kwakasimba kwenguva yakareba, kunyanya munzvimbo dzinopisa zvakanyanya. Zvisinei, tembiricha yepamusoro yekushanda kwezvinhu zvinodziya zvegraphite inokanganiswa nezvinhu zvakasiyana-siyana, nemusiyano mukuru mumiganhu yetembiricha pakati pemhepo nenzvimbo dzevacuum.
Munenharaunda yemhepo, tembiricha yepamusoro yezvinhu zvinodziya zvegraphite inogumira nekuoxidation. Kana chinhu chinodziya chegraphite chikapiswa kusvika pakupisa kwakanyanya, chinopindirana neokisijeni mumhepo kuti chigadzire carbon dioxide (CO₂) kana carbon monoxide (CO₂). Maitiro aya ekuoxidation anotungamira mukuora zvishoma nezvishoma kwezvinhu uye kudzikira kwekushanda, zvichizopedzisira zvakanganisa hupenyu hwechinhu chinodziya. Kazhinji, mumamiriro ekunze akajairwa, tembiricha yepamusoro yekushanda kwezvinhu zvinodziya zvegraphite inenge iri pedyo.3000°CKupfuura tembiricha iyi kunokurumidza kuwedzera kwe oxidation, zvichikonzera kuora kwezvinhu nekukurumidza.
Kusiyana nemhepo, munenzvimbo isina chinhu, oxidation inodzvinyirirwa zvinobudirira. Mu vacuum, huwandu hweokisijeni hunenge zero, saka hapana oxidation inoitika pamusoro pe graphite. Izvi zvinobvumira zvinhu zve graphite kutsungirira tembiricha yakakwira zvikuru. Kutaura zvazviri, mu vacuum, tembiricha yepamusoro ye graphite inogona kusvika3500°Ckana kuti yakakwirira, tembiricha isingawanikwe mumhepo. Zvakanakira zvemamiriro emhepo inoputika hazvingori mukudzora oxidation chete asiwo mukugadzikana kuri nani kwekupisa uye hupenyu hurefu. Izvi zvinoita kuti zvinhu zvinopisa zvegraphite zvive zvakanaka pakushandiswa kwakanyanya kwekupisa kwakanyanya, senge kugadzira semiconductor uye masisitimu ekupisa ekutsvaga muchadenga, uko anowanzo shanda mumamiriro emhepo inoputika kuti ashandise zvizere hunhu hwawo hwezvinhu.
Pamusoro pekuoxidation, simba repamusoro regraphite rinoita basa rakakosha pakuona muganho waro wekupisa. Sezvo tembiricha ichiwedzera, graphite lattice inogona kuchinja zvishoma, kunyanya kana tembiricha ikapfuura huwandu hwakati. Izvi zvinogona kukonzera kuwedzera kwekupisa kana kuumbwa kwekuputika kwepamusoro. Kuchinja uku kwemuviri hakungokanganisi chete hunhu hwe graphite asiwo kunogona kuderedza kugadzikana kwekupisa kwechinhu chinodziya. Naizvozvo, kugara kwenguva refu kwegraphite patembiricha dzakasiyana chinhu chakakosha pakuona kana ichigona kushanda zvakachengeteka uye zvinobudirira munzvimbo dzakati.
Munzvimbo isina chinhu, zvinhu zvinodziya zvegrafiti zvinogona kusvika pakupisa kwakanyanya nekuti hapana oxidation inoparadza zvinhu. Uyezve, mu vacuum, kutamiswa kwekupisa kunoshanda zvakanyanya, sezvo graphite inogona kuendesa kupisa kune workpiece zviri nani pasina kukanganiswa kwe oxidation. Izvi zvinoita kuti zvinhu zvinodziya zvegrafiti zvive zvakanaka kushandiswa mu vacuum fire, laser melting, space heating systems, uye mamwe maapplication ekupisa kwepamusoro-soro.
Zvisinei, pasinei nemabhenefiti akakosha enzvimbo ye vacuum cleaner, zvimwe zvinhu zvinofanirwa kutariswa pakushandisa zvinhu zve graphite mu vacuum cleaner. Semuenzaniso, thermal conductivity ye graphite inogona kuchinja zvishoma nekuda kwekuchinja kwe gas pressure. Saka, kudzora tembiricha yezvinhu zvinodziya zve graphite mumamiriro akasiyana e vacuum kuchiri kufanira kugadziriswa zvichienderana nemamiriro ezvinhu chaiwo. Pamusoro pezvo, kunyangwe oxidation ichidzivirirwa mu vacuum cleaner, mamiriro akanyanya akadai se arc discharge anogona kukanganisa kugadzikana uye kugara kwenguva refu kwe graphite.
Muchidimbu, musiyano uripo mumiganhu yekupisa yezvinhu zvinodziya zvegraphiteMumhepo nenzvimbo dzisina chinhu zvinoratidza kusangana kwakaoma pakati pezvinhu zvezvinhu nezvinhu zvakatipoteredza. Kuokisijeni mumhepo ndicho chinhu chikuru chinodzivisa kugadzikana kwegirafiti pakupisa kwakanyanya, nepo nzvimbo isina chinhu inopa puratifomu isina oxidation, zvichibvumira girafiti kushanda pakupisa kwakanyanya. Pakusarudza zvinhu zvinodziya zvegirafiti zvekushandisa zvakananga, zvakakosha kufunga nezvenzvimbo yekushanda kuti usarudze kana uchishandisa mhepo kana vacuum heating. Kune kupisa kwakasimba uye kwenguva refu, zvinhu zvinodziya zvegirafiti munzvimbo dzisina chinhu pasina mubvunzo zvinobatsira zvikuru.
