Kushandiswa kwezvigadzirwa zvegraphite kwakakwira zvakanyanya kupfuura zvataitarisira, saka ndezvipi zvinoshandiswa zvezvigadzirwa zvegraphite izvo zvatiri kujairana nazvo izvozvi?
1,Inoshandiswa sechinhu conductive
Pakunyungudutsa simbi dzakasiyana-siyana dzealloy, ferroalloys, kana kugadzira calcium carbide (calcium carbide) uye yero phosphorous uchishandisa electric arc furnace kana undermered arc furnace, simba razvino rinounzwa munzvimbo inonyunguduka yechoto chemagetsi kuburikidza nekabhoni electrodes (kana kuenderera kubhaka). maelectrode - kureva electrode paste) kana ma graphitized electrode kugadzira arc, kushandura simba remagetsi kuita simba rekupisa, uye kukwidza tembiricha kusvika kumadhigirii 2000, zvichizadzisa zvinodiwa pakunyungudika kana kuita.Metal magnesium, aluminium, uye sodium zvinowanzogadzirwa neyakanyungudutswa munyu electrolysis.Panguva ino, anode conductive zvinhu zveelectrolytic cell ese magraphite electrodes kana anoenderera ega ega ega maelectrode (anode paste, dzimwe nguva anode yakabikwa kare).Tembiricha yeyakanyungudutswa munyu electrolysis kazhinji iri pasi pe1000 degrees Celsius.Iyo anode conductive zvinhu zvinoshandiswa mumunyu mhinduro electrolysis maseru ekugadzira caustic soda (sodium hydroxide) uye chlorine gasi anowanzo graphitized anode.Iyo conductive zvinhu zvechoto chechoto chevira rekupikisa rinoshandiswa mukugadzira silicon carbide inoshandisawo graphitized electrodes.Pamusoro pezvinangwa zviri pamusoro, zvigadzirwa zvekabhoni nemagraphite zvinoshandiswa zvakanyanya sezvinhu zvinofambisa muindasitiri yekugadzira mota semaringi anotsvedza uye mabhurashi.Uye zvakare, iwo anoshandiswawo sekabhoni rodhi mumabhatiri akaoma, arc light carbon rods yekutsvaga malights kana arc light generation, uye anodes mune mercury rectifiers.

2,Inoshandiswa se refractory material
Nekuda kwekugona kwekabhoni uye zvigadzirwa zvegraphite kutsungirira tembiricha yakakwira uye kuve nepamusoro-tembiricha simba uye kusagadzikana kwekuora, akawanda metallurgical simbi yevira inogona kuvakwa nekabhoni zvidhinha, senge pazasi, pamoto, uye dumbu resimbi inonyungudutsa mavira. lining ye ferroalloy furnaces uye calcium carbide furnaces, uye pasi uye mativi ealuminium electrolytic masero.Mazhinji ma crucibles anoshandiswa kunyungudutsa simbi dzakakosha uye dzisingawanzo, pamwe nema graphitized crucibles anoshandiswa kunyungudutsa quartz girazi, anogadzirwawo kubva kugraphitized billets.Zvigadzirwa zveCarbon uye graphite zvinoshandiswa sezvinhu zvinoramba hazvifanirwe kushandiswa mumhepo ine oxidizing.Nekuti kabhoni kana graphite inokurumidza kupera pasi pekupisa kwakanyanya mumhepo ine oxidizing.
3,Inoshandiswa sechinhu chinodzivirira corrosion structural material
Graphitized maelectrodes akaiswa mukati meorganic kana inorganic resin ane hunhu hwekugona kunaka kwekupokana, yakanaka yekupisa conductivity, uye yakaderera permeability.Rudzi urwu rwe graphite yakanamirwa inozivikanwawo se impermeable graphite.Inoshandiswa zvakanyanya mukugadzirwa kweakasiyana-siyana ekupisa kupisa, matangi ekuita, macondensers, shongwe dzinopisa, shongwe dzekupinza, zvinotonhorera, zvinopisa, mafirita, pombi, uye zvimwe midziyo.Inoshandiswa zvakanyanya mumaindasitiri akadai sekunatsa peturu, petrochemical, hydrometallurgy, asidhi uye alkali kugadzirwa, synthetic fibers, papermaking, uye inogona kuchengetedza yakawanda simbi zvinhu zvakaita sesimbi isina tsvina.Kugadzirwa kweimpermeable graphite kwave chikamu chakakosha cheiyo carbon industry.

4,Inoshandiswa sechinhu chinodzivirira kupfeka uye mafuta ekuzora
Carbon uye graphite zvinhu hazvina kugadzikana kwemakemikari chete, asiwo zvine maitiro akanaka ekuzora.Kazhinji hazvigoneke kuvandudza kupfeka kuramba kwezvikamu zvinotsvedza uchishandisa mafuta ekuzora pasi pekumhanya-mhanya, kutonhora kwakanyanya, uye kudzvanywa kwemamiriro.Graphite isingagadzirike zvinhu zvinokwanisa kushanda pasina kuzora mafuta mumidhiya inoparadza patembiricha kubva -200 kusvika 2000 madhigirii celsius uye pakutsvedza kwakanyanya (kusvika 100 metres/sekondi).Naizvozvo, macompressor mazhinji nemapombi anotakura corrosive media anoshandisa mhete dzepiston, zvindori zvekuisa chisimbiso, uye mabearings akagadzirwa nezvinhu zvegraphite.Havadi kuwedzerwa kwemafuta panguva yekushanda.Ichi chinodzivirira kupfeka chinogadzirwa nekuisa zvakajairwa kabhoni kana magirafu zvinhu zvine organic resin kana mvura yesimbi zvinhu.Graphite emulsion zvakare yakanaka lubricant kune akawanda simbi kugadzirisa (senge waya kudhirowa uye chubhu kudhirowa).

5,Sechinhu chepamusoro-tembiricha metallurgical uye ultrapure zvinhu
Zvimiro zvekugadzira zvinoshandiswa mukugadzira, senge kristaro yekukura crucibles, yedunhu yekunatsa midziyo, mabhuraketi, zvigadziriso, induction heaters, nezvimwe, zvese zvinogadziriswa kubva kune yakakwira-kuchena graphite zvinhu.Graphite insulation mabhodhi uye mabhesi anoshandiswa muvacuum smelting, pamwe nezvikamu zvakaita seyepamusoro-tembiricha yekudzivirira machubhu, tsvimbo, mahwendefa, uye magidhi, zvakare akagadzirwa nezvinhu zvegraphite.ona zvimwe pa www.futmetal.com
