Ukusetshenziswa kwemikhiqizo ye-graphite kuphakeme kakhulu kunalokho ebesikulindele, ngakho-ke yiziphi izinto ezisetshenziswayo zemikhiqizo ye-graphite esiyijwayele njengamanje?
1,Isetshenziswa njengento conductive
Lapho kuncibilika izinsimbi ezihlukahlukene zengxubevange, ama-ferroalloys, noma kukhiqizwa i-calcium carbide (i-calcium carbide) ne-phosphorus ephuzi kusetshenziswa isithando somlilo se-arc sikagesi noma isithando somlilo se-arc esingaphansi kwamanzi, igagasi elinamandla lingeniswa endaweni yokuncibilika yesithando sikagesi ngokusebenzisa ama-electrode e-carbon (noma ukuzibhakela okuqhubekayo. ama-electrode - okungukuthi i-electrode paste) noma ama-electrode enziwe ama-graphitized ukuze akhe i-arc, aguqule amandla kagesi abe amandla okushisa, futhi akhuphule izinga lokushisa libe cishe ku-2000 degrees Celsius, ngaleyo ndlela ehlangabezana nezidingo zokuncibilika noma ukusabela. I-Metal magnesium, i-aluminium, ne-sodium ngokuvamile ikhiqizwa yi-electrolysis kasawoti encibilikisiwe. Ngalesi sikhathi, izinto ze-anode conductive zeseli ye-electrolytic wonke ama-electrode egraphite noma ama-electrode okubhaka aqhubekayo (i-anode paste, kwesinye isikhathi i-anode ebhakwe ngaphambilini). Izinga lokushisa le-electrolysis kasawoti oncibilikisiwe ngokuvamile lingaphansi kuka-1000 degrees Celsius. Izinto ze-anode conductive ezisetshenziswa kumaseli e-electrolysis esisombululo sikasawoti sokukhiqiza i-caustic soda (i-sodium hydroxide) kanye negesi ye-chlorine ngokuvamile ama-anode e-graphitized. Izinto eziqhutshwayo zekhanda lesithando somlilo esisetshenziswa ekukhiqizeni i-silicon carbide futhi zisebenzisa ama-electrode e-graphitized. Ngaphezu kwalezi zinhloso ezingenhla, imikhiqizo yekhabhoni ne-graphite isetshenziswa kakhulu njengezinto ezisetshenziswayo embonini yokukhiqiza izimoto njengezindandatho zokushelela namabhulashi. Ngaphezu kwalokho, asetshenziswa futhi njengama-carbon rods kumabhethri omile, ama-arc light carbon rods wezibani zokusesha noma i-arc light generation, nama-anode kuma-mercury rectifiers.

2,Isetshenziswa njengento ephikisayo
Ngenxa yekhono lemikhiqizo ye-carbon ne-graphite yokumelana namazinga okushisa aphezulu futhi ibe namandla amahle okushisa aphezulu kanye nokumelana nokugqwala, izindwangu eziningi zesithando somlilo zingakhiwa ngamabhulokhi ekhabhoni, njengendawo engezansi, iziko, nesisu seziko lokuncibilikisa insimbi, ulwelwesi lweziko le-ferroalloy kanye neziko le-calcium carbide, kanye nezansi nezinhlangothi zamaseli e-aluminium electrolytic. Izikhisi eziningi ezisetshenziselwa ukuncibilikisa izinsimbi eziyigugu nezingavamile, kanye nezikhisi ezinezithombe ezisetshenziselwa ukuncibilikisa ingilazi ye-quartz, nazo zenziwe ngamabhilidi enziwe ngama-graphitized. Imikhiqizo yekhabhoni kanye ne-graphite esetshenziswa njengezinto eziphikisayo akufanele ngokuvamile isetshenziswe endaweni ene-oxidizing. Ngoba ikhabhoni noma i-graphite ishesha ukucisha ngaphansi kwamazinga okushisa aphezulu endaweni ene-oxidizing.
3,Isetshenziswa njengezinto zesakhiwo ezimelana nokugqwala
Ama-electrode aqoshiwe afakwe ama-organic or inorganic resins anezici zokumelana nokugqwala okuhle, ukuguquguquka okuhle kwe-thermal, kanye nokungeneka okuphansi. Lolu hlobo lwe-graphite olufakiwe lwaziwa nangokuthi i-graphite engavunyelwe. Isetshenziswa kabanzi ekukhiqizeni ama-heaters ahlukahlukene, amathangi okuphendula, ama-condensers, imibhoshongo evuthayo, imibhoshongo yokumuncwa, ama-coolers, ama-heaters, izihlungi, amaphampu, nezinye izinto zokusebenza. Isetshenziswa kabanzi emikhakheni yezimboni efana nokuhluzwa kwe-petroleum, i-petrochemical, i-hydrometallurgy, ukukhiqizwa kwe-asidi ne-alkali, imicu yokwenziwa, ukwenza iphepha, futhi ingasindisa izinto eziningi zensimbi njengensimbi engagqwali. Ukukhiqizwa kwe-graphite engangenisi sekuyigatsha elibalulekile lemboni ye-carbon.

4,Isetshenziswa njengento engagugi futhi yokugcoba
Izinto ze-Carbon ne-graphite azigcini nje ngokuzinza kwamakhemikhali aphezulu, kodwa futhi zinezindawo ezinhle zokugcoba. Ngokuvamile akunakwenzeka ukuthuthukisa ukumelana nokugqoka kwezingxenye ezishelelayo usebenzisa uwoyela wokugcoba ngaphansi kwezimo zejubane eliphezulu, izinga lokushisa eliphezulu, nokucindezela okukhulu. Izinto ezikwazi ukumelana nokugqokwa kwe-graphite zingasebenza ngaphandle kokugcoba uwoyela emithonjeni ebolayo emazingeni okushisa asukela ku -200 kuya ku-2000 degrees Celsius futhi ngesivinini esishelelayo esikhulu (kufika ku-100 amamitha/ngesekhondi). Ngakho-ke, ama-compressor amaningi namaphampu athutha imidiya ebolayo asebenzisa kakhulu izindandatho ze-piston, izindandatho zokuvala, nama-bearings enziwe ngezinto ze-graphite. Azidingi ukungezwa kwamafutha ngesikhathi sokusebenza. Le nto ekwazi ukumelana nokugqokwa yenziwa ngokufaka i-carbon evamile noma izinto ze-graphite nge-organic resin noma izinto eziwuketshezi zensimbi. I-emulsion ye-graphite nayo iyisigcobo esihle sokucutshungulwa kwensimbi okuningi (njengokudweba ngocingo nokudweba kweshubhu).

5,Njengesisetshenziswa esisezingeni eliphezulu se-metallurgical kanye ne-ultrapure
Izinto zesakhiwo ezisetshenziswa ekukhiqizeni, njenge-crystal ukukhula crucibles, iziqukathi zokucwenga zesifunda, abakaki, izinto ezilungiswayo, izifudumezi zokungeniswa, njll., konke kucutshungulwa kusuka ezintweni ezihlanzekile zegraphite. Amabhodi okufakwa kwe-graphite nezisekelo ezisetshenziswa ekuncibilikeni kwe-vacuum, kanye nezingxenye ezinjengamashubhu esithandweni esithandweni sokushisa aphezulu, izinduku, amapuleti, namagridi, nazo zenziwe ngezinto ze-graphite. bheka okuningi ku-www.futmetal.com
