Ukusetyenziswa kweemveliso zegraphite kuphezulu kakhulu kunokuba besilindele, ngoko zeziphi ukusetyenziswa kweemveliso zegraphite esiziqhelileyo ngoku?
1,Isetyenziswe njengesixhobo sokuqhuba
Xa kunyibilikiswa iintsimbi ezahlukeneyo zealloyi, iiferroalloys, okanye ukuvelisa icalcium carbide (icalcium carbide) kunye nephosphorous emthubi kusetyenziswa isithando sombane se-arc okanye isithando somlilo esintywiliselweyo, umsinga onamandla ungeniswa kwindawo yokunyibilika yeziko lombane ngokusebenzisa i-carbon electrode (okanye ukubhaka ngokuqhubekayo. i-electrode - oko kukuthi i-electrode paste) okanye i-electrode yegraphitized ukwenza i-arc, ukuguqula amandla ombane abe ngamandla obushushu, kunye nokunyusa amaqondo obushushu aye malunga nama-2000 degrees celcius, ngaloo ndlela ehlangabezana neemfuno zokunyibilikiswa okanye ukusabela. I-Metal magnesium, i-aluminium, kunye ne-sodium ziveliswa ngokubanzi nge-electrolysis yetyuwa etyhidiweyo. Ngeli xesha, imathiriyeli ye-anode conductive yeseli ye-electrolytic zonke zi-electrode zegraphite okanye i-electrodes yokubhaka eqhubekayo (i-anode paste, ngamanye amaxesha i-anode ebhakwe ngaphambili). Ubushushu be-electrolysis yetyuwa enyibilikisiweyo ngokuqhelekileyo bungaphantsi kwe-1000 degrees Celsius. Izixhobo zokuqhuba i-anode ezisetyenziswa kwisisombululo setyuwa iiseli ze-electrolysis zokuvelisa i-caustic soda (i-sodium hydroxide) kunye negesi ye-chlorine zidla ngokuba zii-anode zegraphitized. Izinto eziqhubayo zentloko yesithando somlilo esisetyenziswa ekuveliseni i-silicon carbide ikwasebenzisa i-electrode yegraphitized. Ukongeza kwezi njongo zingentla, iimveliso zekhabhoni kunye negraphite zisetyenziswa ngokubanzi njengezinto zokuqhuba kwishishini lokwenziwa kweemoto njengeringi zokutyibilika kunye neebhrashi. Ukongeza, zikwasetyenziswa njengeentsimbi zekhabhoni kwiibhetri ezomileyo, ii-arc light lights zekhabhoni zokukhangela izibane okanye i-arc light generation, kunye ne-anode kwi-mercury rectifiers.

2,Isetyenziswe njengezinto eziphikisayo
Ngenxa yobuchule bekhabhoni kunye neemveliso zegraphite ukumelana nobushushu obuphezulu kwaye zibe namandla aphezulu obushushu obuphezulu kunye nokumelana nokugqwala, iileyile ezininzi zesithando somlilo zinokwakhiwa ngeebhloko zekhabhoni, ezinje ngasezantsi, eziko, kunye nesisu seziko lokunyibilikisa intsimbi, umgca we-ferroalloy furnaces kunye ne-calcium carbide furnaces, kunye nezantsi kunye namacala eeseli ze-aluminium electrolytic. Izikhonkwane ezininzi ezisetyenziselwa ukunyibilikisa isinyithi esixabisekileyo kunye nenqabileyo, kunye ne-graphitized crucibles esetyenziselwa ukunyibilikisa iglasi ye-quartz, nazo zenziwe kwiibhilithi zegraphiti. Iimveliso zekhabhoni kunye negraphite ezisetyenziswa njengezinto ezichasayo akufuneki zisetyenziswe ngokubanzi kwiatmosphere ezine-oxidizing. Ngenxa yokuba ikhabhoni okanye igraphite ikhawuleza igqabhuke phantsi kobushushu obuphezulu kwiatmosfera ene-oxidizing.
3,Isetyenziswa njengesixhobo solwakhiwo olumelana nokutyiwa
Ii-electrode ezifakwe kwigraphiti ezifakwe kwi-organic or inorganic resins zineempawu zokumelana ne-corrosion elungileyo, ukuhanjiswa kakuhle kwe-thermal, kunye nokungena kancinci. Olu hlobo lwegraphite efakiweyo lukwabizwa ngokuba yigraphite enganyibilikiyo. Isetyenziswa ngokubanzi kwimveliso yeendlela ezahlukeneyo zokutshintsha ubushushu, iitanki zokusabela, i-condensers, iinqaba zokutsha, iinqaba zokufunxa, ii-coolers, izifudumezi, izihluzi, iimpompo kunye nezinye izixhobo. Isetyenziswa ngokubanzi kumacandelo oshishino afana nokucokisa i-petroleum, i-petrochemical, i-hydrometallurgy, i-asidi kunye nokuveliswa kwe-alkali, iifayili zokwenziwa, i-papermaking, kwaye inokugcina izinto ezininzi zetsimbi ezifana nensimbi engenasici. Imveliso yegraphite engagxumekiyo ibe lisebe elibalulekileyo loshishino lwekhabhoni.

4,Isetyenziswa njengesixhobo sokungagugi kunye nokuthambisa
Izinto zekhabhoni kunye negraphite azikho nje ukuzinza kweekhemikhali eziphezulu, kodwa zineempawu ezintle zokuthambisa. Ngokuqhelekileyo akunakwenzeka ukuphucula ukunyanzeliswa kokunxiba kwamacandelo e-sliding usebenzisa ioli yokuthambisa phantsi kwesantya esiphezulu, ubushushu obuphezulu, kunye neemeko zoxinzelelo oluphezulu. Izinto ze-graphite ezikwaziyo ukunxiba zingasebenza ngaphandle kokuthambisa ioli kwimidiya ebolileyo kumaqondo obushushu ukusuka kwi-200 ukuya kuma-2000 degrees Celsius kunye nesantya esiphezulu sokutyibilika (ukuya kuthi ga kwi-100 yeemitha / ngomzuzwana). Ke ngoko, iicompressor ezininzi kunye neempompo ezithutha imidiya ebolileyo zisebenzisa kakhulu amakhonkco episton, imisesane yokutywina, kunye neebheringi ezenziwe ngezinto zegraphite. Abafuni ukongezwa kwee-lubricants ngexesha lokusebenza. Esi sixhobo sokumelana nokunxiba senziwe ngokufaka i-carbon eqhelekileyo okanye izixhobo zegraphite kunye ne-organic resin okanye i-liquid metal materials. I-emulsion ye-graphite ikwasithambisi esilungileyo sokulungiswa kwesinyithi (njengomzobo wecingo kunye nomzobo wetyhubhu).

5,Njengobushushu obuphezulu be-metallurgical kunye ne-ultrapure
Izinto ezisetyenziselwa ukuveliswa kwemveliso, ezifana ne-crystal growth crucibles, iziqulathi zokucoca zengingqi, iibrakethi, izixhobo, izifudumezi ze-induction, njl., Zonke zicutshungulwa kwizinto ezicocekileyo zegraphite. Iibhodi zokugquma i-graphite kunye neziseko ezisetyenziswa kwi-vacuum smelting, kunye namacandelo afana ne-high-temperature resistant furnace tubes, iintonga, iipleyiti kunye neegridi, nazo zenziwe ngezinto zegraphite. bona ngakumbi www.futmetal.com
