Impembelelo yoxinano lwegrafiti ekusebenzeni kwe-electrode ibonakala kakhulu kwezi zinto zilandelayo:
- Amandla oomatshini kunye ne-Porosity
- Ulwalamano oluhle phakathi koxinano kunye namandla oomatshini: Ukwandisa uxinano lwee-electrode ze-graphite kunciphisa ukubola kwaye kwandisa amandla oomatshini. Ii-electrode ezinoxinano oluphezulu zimelana ngcono neempembelelo zangaphandle kunye noxinzelelo lobushushu ngexesha lokunyibilikisa i-arc furnace yombane okanye i-electrical discharge machining (EDM), kunciphisa umngcipheko wokuqhekeka okanye ukuqhekeka.
- Impembelelo ye-porosity: Ii-electrode ezinoxinano oluphantsi, ezine-porosity ephezulu, zinomngcipheko wokungena kwe-electrolyte okungalinganiyo, nto leyo ekhawulezisa ukuguguleka kwe-electrode. Ngokwahlukileyo koko, ii-electrode ezinoxinano oluphezulu zandisa ubomi benkonzo ngokunciphisa i-porosity.
- Ukumelana ne-Oxidation
- Ulwalamano oluhle phakathi koxinano kunye nokumelana ne-oxidation: Ii-electrode ze-graphite ezinoxinano oluphezulu zinesakhiwo sekristale esixineneyo, esithintela ngokufanelekileyo ukungena kwe-oksijini kwaye sinciphise amazinga e-oxidation. Oku kubaluleke kakhulu kwiinkqubo zokunyibilikisa okanye ze-electrolysis kubushushu obuphezulu, kunciphisa ukusetyenziswa kwe-electrode.
- Imeko yokusetyenziswa: Kwi-electric arc furnace steelmaking, ii-electrode ezinoxinano oluphezulu zinciphisa ukuncipha kobubanzi obubangelwa yi-oxidation, zigcina ukusebenza kakuhle kokuqhuba kombane okuzinzileyo.
- Ukumelana noTshabalalo oluTshisayo kunye nokuHanjiswa koBushushu
- Ukutshintshiselana phakathi koxinano kunye nokumelana noxinzelelo lobushushu: Uxinano oluphezulu kakhulu lunokunciphisa ukumelana noxinzelelo lobushushu, lunyuse ukuchaneka kokuqhekeka phantsi kotshintsho olukhawulezileyo lobushushu. Umzekelo, kwi-EDM, ii-electrode ezinoxinano oluphantsi zibonisa uzinzo olukhulu ngenxa yomlinganiselo wazo wokwandiswa kobushushu ophantsi.
- Amanyathelo okuphucula: Ukuphucula ukuhanjiswa kobushushu ngokunyusa ubushushu begrafiti (umz., ukusuka kwi-2800°C ukuya kwi-3000°C) okanye ukusebenzisa i-needle coke njengezinto eziluhlaza ukunciphisa i-thermal expansion coefficient kunokuphucula ukumelana noxinzelelo lobushushu ngelixa kugcinwa uxinano oluphezulu.
- Ukuqhuba koMbane kunye nokuSebenza kakuhle
- Uxinano kunye nokuhanjiswa kombane: Ukuhanjiswa kombane kwee-electrode ze-graphite kuxhomekeke kakhulu kwi-crystalline structure integrity endaweni yoxinano kuphela. Nangona kunjalo, ii-electrode ezinoxinano oluphezulu zihlala zibonelela ngeendlela zamandla ezifanayo ngenxa yokuncipha kwe-porosity, nto leyo enciphisa ubushushu obuphezulu bendawo.
- Ukukwazi ukusebenza ngomatshini: Ii-electrode zegrafiti ezinoxinano oluphantsi zithambile kwaye kulula ukuzisebenzisa ngomatshini, zinesantya sokusika esiphindwe kathathu ukuya kahlanu kunee-electrode zobhedu kwaye zincinci kakhulu ukuguguleka kwezixhobo. Nangona kunjalo, ii-electrode ezinoxinano oluphezulu zibalasele ngokuqina komlinganiselo ngexesha lokwenziwa ngomatshini ngokuchanekileyo.
- Ukunxiba kwe-Electrode kunye nokusebenza kakuhle kweendleko
- Uxinano kunye nezinga lokuguguleka: Ii-electrode ezinoxinano oluphezulu zenza iileya zokukhusela (umz., amasuntswana ekhabhoni anamatheleyo) ngexesha lokwenziwa komatshini wokukhupha, zihlawulela ukuguguleka kwaye zifezekisa "ukuguguleka okungekho" okanye ukuguguleka okuphantsi. Umzekelo, kwi-EDM yezinto zokusebenza zentsimbi yekhabhoni, izinga lokuguguleka kwazo linokuba ngaphantsi ngama-30% kunelee-electrode zobhedu.
- Uhlalutyo lweendleko-inzuzo: Nangona iindleko eziphezulu zezinto ezikrwada, ii-electrode ezinoxinano oluphezulu zinciphisa iindleko zokusetyenziswa ngokubanzi ngenxa yobomi bazo obude kunye nokungonakali kwazo, ingakumbi kwi-mold machining enkulu.
- Ukulungiswa kwezicelo ezikhethekileyo
- Ii-anode zebhetri yeLithium-ion: Uxinano lwetaphu lwee-anode ze-graphite (1.3–1.7 g/cm³) luchaphazela ngokuthe ngqo uxinano lwamandla ebhetri. Uxinano lwetaphu oluphezulu kakhulu luthintela ukufuduka kwee-ion, lunciphisa ukusebenza kwesantya, ngelixa uxinano oluphantsi kakhulu lunciphisa ukuhanjiswa kwe-elektroniki. Ukulinganisela ukusebenza kufuna ukuhlelwa kobukhulu bee-particle kunye nokuguqulwa komphezulu.
- Iimodareyitha ze-neutron kwi-reactors zenyukliya: I-graphite enoxinano oluphezulu (umz., uxinano oluyi-2.26 g/cm³) iphucula iindawo ezinqamlezayo ze-neutron, iphucula ukusebenza kakuhle kwe-nuclear reaction ngelixa igcina uzinzo lweekhemikhali.
