Sei ma electrode e graphite achigona kutsungirira mamiriro ekunze anodziya zvakanyanya?
Ma electrode e graphite anoita basa rakakosha mumaindasitiri emazuva ano, kunyanya mukushandiswa munzvimbo dzinopisa zvakanyanya, senge electric arc furnace steel making, aluminum electrolysis, uye electrochemical processing. Chikonzero chinoita kuti ma electrode e graphite agone kutsungirira nzvimbo dzinopisa zvakanyanya chinokonzerwa nehunhu hwavo hwakasiyana hwepanyama nemakemikari. Chinyorwa chino chichaongorora zvakadzama mashandiro akanaka ema electrode e graphite munzvimbo dzinopisa zvakanyanya kubva pazvinhu zvakaita sechimiro, hunhu hwekupisa, kugadzikana kwemakemikari, uye simba re graphite.
1. Hunhu hwegirafiti
Graphite imhando yechinhu chakaumbwa nemaatomu ekabhoni. Muchimiro chekristaro chegraphite, maatomu ekabhoni akarongwa muchikamu chehexagonal planar layer. Maatomu ekabhoni ari mukati mechikamu chimwe nechimwe akabatana nezvisungo zvakasimba zvecovalent, nepo zvikamu zvichidyidzana kuburikidza nemasimba asina simba evan der Waals. Chimiro ichi chakaumbwa nezvikamu chinopa graphite hunhu hwakasiyana hwepanyama nemakemikari.
Zvisungo zvakasimba zvecovalent mukati mezvikamu: Zvisungo zvecovalent pakati pemaatomu ekabhoni mukati mezvikamu zvakasimba zvikuru, zvichiita kuti graphite irambe yakagadzikana kunyangwe pakupisa kwakanyanya.
Simba risina simba reVan der Waals pakati pezvikamu: Kudyidzana pakati pezvikamu hakuna kusimba, izvo zvinoita kuti graphite ikwanise kutsvedza pakati pezvikamu kana ichishandiswa nemasimba ekunze. Hunhu uhwu hunopa graphite mafuta akanaka uye kugona kushandiswa.
2. Hunhu hwekupisa
Kushanda zvakanaka kwema graphite electrodes munzvimbo dzine tembiricha yakakwira kunonyanya kukonzerwa nehunyanzvi hwavo hwekupisa.
Nzvimbo yekunyunguduka kwakanyanya: Graphite ine nzvimbo yekunyunguduka yakanyanya, inenge 3,652 °C, iyo yakanyanya kupfuura yesimbi dzakawanda ne alloys. Izvi zvinoita kuti graphite irambe yakasimba pakupisa kwakanyanya isina kunyunguduka kana kuchinja.
Kupisa kwakanyanya: Graphite ine kupiswa kwakanyanya, iyo inogona kukurumidza kuendesa nekuparadzira kupisa, ichidzivirira kupisa kwakanyanya munzvimbo. Hunhu uhwu hunogonesa graphite electrode kuparadzira kupisa zvakaenzana munzvimbo dzine tembiricha yepamusoro, kuderedza kushushikana kwekupisa uye kuwedzera hupenyu hwebasa.
Kuwanda kwemafuta eGraphite kwakaderera: Graphite ine kuwanda kwemafuta eGraphite kwakaderera, zvinoreva kuti vhoriyamu yayo inochinja zvishoma kana tembiricha yakakwira. Hunhu uhwu hunogonesa maelectrode eGraphite kuchengetedza kugadzikana kwezvikamu munzvimbo dzine tembiricha yakakwira, zvichideredza kupwanyika kwestress uye kushanduka kunokonzerwa nekuwedzera kwemafuta eGraphite.
3. Kugadzikana kwemakemikari
Kugadzikana kwemakemikari ema graphite electrodes munzvimbo dzine tembiricha yakakwira ndeimwe yezvinhu zvakakosha kuti akwanise kutsungirira tembiricha yakakwira.
Kuramba kuoxidation: Pakupisa kwakanyanya, graphite inochinja-chinja ine okisijeni inononoka, kunyanya mumagasi asina simba kana mumhepo inodzikisa, uko graphite inochinja-chinja ine okisijeni yakaderera. Kuramba kuoxidation uku kunoita kuti maelectrode egraphite ashandiswe kwenguva yakareba munzvimbo dzine tembiricha yakakwira pasina kuoxidation kana kusakara.
Kuramba ngura: Graphite inodzivirira ngura zvakanaka kune akawanda maacid, alkalis nemunyu, izvo zvinoita kuti ma electrode e graphite arambe akagadzikana munzvimbo dzinopisa zvakanyanya uye dzinopisa. Semuenzaniso, panguva yekushandiswa kwe electrolytic ye aluminium, ma electrode e graphite anogona kutsungirira ngura ye aluminium yakanyungudutswa ne fluoride salts.
4. Simba remuchina
Kunyangwe kudyidzana kwepakati pegirafiti kusina kusimba, zvisungo zvakasimba zvecovalent mukati mechimiro chayo chemukati memellar zvinopa girafiti simba rakawanda remuchina.
Simba rekudzvanya rakakwirira: Maelectrode eGraphite anogona kuchengetedza simba rekudzvanya rakakwirira kunyangwe pakupisa kwakanyanya, achikwanisa kutsungirira kumanikidzwa kwakanyanya uye mutoro wekukanganisa mumaovheni emagetsi e arc.
Kudzivirira kupisa kwakanyanya: Kuwanda kwekuwedzera kwekupisa uye graphite yakawanda inoidzivirira kupisa zvakanyanya, zvichiita kuti ikwanise kuchengetedza chimiro chayo panguva yekupisa nekukurumidza uye kuderedza kutsemuka nekukuvadzwa kunokonzerwa nekushushikana kwekupisa.
5. Zvimiro zvemagetsi
Kushanda kwemagetsi kwema graphite electrodes munzvimbo dzinopisa zvakanyanya ndicho chikonzero chakakosha chekushandiswa kwawo kwakafara.
Kufambiswa kwemagetsi kwakanyanya: Graphite ine kufambiswa kwemagetsi kwakanaka kwazvo, izvo zvinogona kufambisa magetsi zvinobudirira uye kuderedza kurasikirwa kwemagetsi. Hunhu uhwu hunogonesa maerekitirodhi egraphite kufambisa simba remagetsi zvinobudirira mumidziyo yemagetsi yearc uye maitiro eelectrolysis.
Kusasimba kwepasi: Kusasimba kwegirafiti kunoigonesa kuchengetedza kusasimba kwepasi pakupisa kwakanyanya, zvichideredza kugadzirwa kwekupisa uye kurasikirwa nesimba, uye kuvandudza kushandiswa kwesimba zvakanaka.
6. Kugadzirisa mashandiro
Kushanda kwema graphite electrodes pakugadzirisa zvinhu chinhu chakakoshawo pakushandiswa kwawo munzvimbo dzinopisa zvakanyanya.
Kugadziriswa kuri nyore: Graphite inogona kugadziriswa zvakanaka uye inogona kugadziriswa kuita maerekitirodhi emhando dzakasiyana-siyana nehukuru kuburikidza nekugadzira michina, kutenderedza, kugaya uye mamwe matekiniki kuti ienderane nezvinodiwa nemamiriro akasiyana ekushandisa.
Kuchena kwakanyanya: Maelectrode egirafiti akachena zvakanyanya ane kugadzikana uye mashandiro ari nani munzvimbo dzinopisa zvakanyanya, izvo zvinogona kuderedza mhedzisiro yemakemikari uye zvikanganiso zvechimiro zvinokonzerwa nekusvibiswa.
7. Mienzaniso yeKushandisa
Maelectrode eGraphite anoshandiswa zvakanyanya muminda yakawanda yemaindasitiri inodziya zvakanyanya. Mienzaniso yekushandiswa kwakajairika:
Kugadzira simbi muchoto chemagetsi: Mukugadzira simbi muchoto chemagetsi chemagetsi, ma electrode e graphite, sezvinhu zvinofambisa mhepo, anogona kutsungirira tembiricha inosvika 3000°C, achishandura simba remagetsi kuita simba rinopisa kuti anyungudise simbi yakapwanyika nesimbi yenguruve.
Aruminiyamu yeElectrolytic: Munguva yekugadzirwa kwearuminiyamu yeelectrolytic, graphite electrode inoshanda seanode, inokwanisa kutsungirira tembiricha yakakwira uye ngura yearuminiyamu yakanyungudutswa nefluoride salts, ichitungamira magetsi zvakadzikama, uye ichikurudzira kugadzirwa kwearuminiyamu yeelectrolytic.
Kugadzira nemagetsi: Mukugadzira nemagetsi, ma electrode e graphite, sema electrode ezvishandiso, anogona kushanda zvakadzikama munzvimbo dzine tembiricha yakakwira uye dzinoparadza, zvichiita kuti kugadzirwa nekuumbwa kuve kwakanyatsojeka.
Mhedziso
Mukupedzisa, chikonzero nei ma electrode e graphite achigona kutsungirira nharaunda dzine tembiricha yepamusoro chiri muchimiro chawo chakasiyana, hunhu hwakanaka hwekupisa, kugadzikana kwemakemikari, simba remakanika, hunhu hwemagetsi uye mashandiro ekugadzirisa. Hunhu uhwu hunogonesa ma electrode e graphite kuti arambe akasimba uye achishanda zvakanaka munzvimbo dzine tembiricha yepamusoro uye dzinopisa, uye anoshandiswa zvakanyanya munzvimbo dzakadai se electric arc furnace steelmaking, electrolytic aluminum, uye electrochemical processing. Nekuvandudzwa kuri kuramba kuchiitwa tekinoroji yeindasitiri, mashandiro uye huwandu hwekushandiswa kwema electrode e graphite huchawedzerwa, zvichipa mhinduro dzakavimbika uye dzinoshanda kumaindasitiri ane tembiricha yepamusoro.
