Kamora Letsatsi la Naha, theko ea liodara tse ling 'marakeng oa graphite e tla nyoloha ka hoo e ka bang 1,000-1,500 yuan/ton ho tloha nakong e fetileng. Hona joale, ho ntse ho e-na le maikutlo a ho leta le ho bona ha ho rekoa liindasteri tsa tšepe tsa graphite electrode tse theohelang tlaase, 'me litšebelisano tsa' maraka li ntse li fokola. Leha ho le joalo, ka lebaka la phepelo e thata ea 'maraka oa graphite electrode le litšenyehelo tse phahameng, lik'hamphani tsa graphite electrode li sutumelletsa ka matla theko ea li-electrode tsa graphite ka lebaka la ho se rate ho rekisa, 'me theko ea' maraka e fetoha ka potlako. Mabaka a itseng a susumetsang ke a latelang:
1. Tlas'a tšusumetso ea khaello ea motlakase, phepelo ea 'maraka oa li-electrode tsa graphite e lebelletsoe ho fokotseha
Ka lehlakoreng le leng, kamora ho sebelisoa ha likhoeli tse ka bang 2, lenane la 'maraka oa li-electrode tsa graphite le fokotsehile, 'me lik'hamphani tse ling tsa li-electrode tsa graphite li bontšitse hore khamphani ha e na lenane la lintho tse rekisoang;
Ka lehlakoreng le leng, tlas'a tšusumetso ea khaello ea phepelo ea motlakase e qalileng bohareng ba Loetse, liprofinse tse fapaneng li tlalehile lithibelo tsa motlakase ka tatellano, 'me lithibelo tsa motlakase li eketsehile butle-butle. Tlhahiso ea 'maraka oa graphite electrode e lekanyelitsoe 'me phepelo e fokotsehile.
Ho fihlela jwale, moedi wa motlakase dibakeng tse ngata o shebane le 20%-50%. Ho Inner Mongolia, Liaoning, Shandong, Anhui, le Henan, tshusumetso ya dithibelo tsa motlakase e tebile haholo, ha e le hantle e ka ba 50%. Har'a tsona, dikgwebo tse ding ho Inner Mongolia le Henan di thibetswe haholo. Tshusumetso ya motlakase e ka fihla ho 70%-80%, mme dikhamphani ka bomong di na le ho kwalwa ha mesebetsi.
Ho ya ka dipalopalo mabapi le tlhahiso ya dikhamphani tse 48 tse kgolo tsa electrode ya graphite naheng, tse itshetlehileng hodima palo ya tlhahiso ya di-electrode tsa graphite ka Loetse, mme di balwa ho ya ka karolo ya motlakase o fokolang mmarakeng wa electrode ya graphite pele ho nako ya "Eleventh", ho lebelletswe hore tlhahiso ya kgwedi le kgwedi ya mmaraka wa electrode ya graphite e tla fokotseha ka ditone tse 15,400 ka kakaretso; Kamora nako ya "Eleventh", mmaraka wa electrode ya graphite o lebelletswe ho fokotsa tlhahiso yohle ya kgwedi le kgwedi ka ditone tse 20,500. Ho ka bonwa hore moedi wa matla wa mmaraka wa electrode ya graphite o matlafetse kamora matsatsi a phomolo.
Ho phaella moo, ho utlwisiseha hore dikhamphani tse ding Hebei, Henan le dibakeng tse ding di fumane tsebiso ya moedi wa tlhahiso ya tshireletso ya tikoloho ya hoetla le mariha, mme dikhamphani tse ding tsa di-electrode tsa graphite di ke ke tsa qala kaho ka lebaka la boemo ba lehodimo ba mariha. Sekgahla le dithibelo tsa mmaraka wa di-electrode tsa graphite di tla eketswa le ho feta.
2. Litšenyehelo tsa 'maraka oa li-electrode tsa graphite li ntse li eketseha
Litheko tse holimo tsa thepa e tala bakeng sa li-electrode tsa graphite li ntse li eketseha
Kamora Letsatsi la Naha, litheko tsa coke ea petroleum e nang le sulfur e tlase, sekontiri sa mashala le nale coke, e leng thepa e tala e holimo ea li-electrode tsa graphite, li nyolohile ho pholletsa le boto. Ka lebaka la ho phahama ha theko ea sekontiri sa mashala le seretse sa oli, ho lebeletsoe hore li-coke tsa needle tse tsoang kantle ho naha le nale coke tsa lapeng li tla tsoela pele ho nyoloha ka matla. Tsoela pele ho hatella ka boemo bo holimo.
Ha ho baloa ho latela litheko tsa hona joale tsa thepa e tala, ka khopolo-taba, litšenyehelo tse felletseng tsa tlhahiso ea li-electrode tsa graphite ke hoo e ka bang li-yuan tse 19,000/tonne. Likhamphani tse ling tsa li-electrode tsa graphite li boletse hore tlhahiso ea tsona e lahlehetsoe.
Tlas'a tšusumetso ea khaello ea motlakase, litšenyehelo tsa ts'ebetso ea 'maraka oa li-electrode tsa graphite li eketsehile
Ka lehlakoreng le leng, tlas'a tšusumetso ea phokotso ea matla, ts'ebetso ea graphitization ea lik'hamphani tsa electrode ea graphite e thibetsoe haholo, haholo-holo libakeng tse nang le litheko tse tlase tsa motlakase joalo ka Inner Mongolia le Shanxi; ka lehlakoreng le leng, phaello ea graphitization ea electrode e mpe e tšehetsoa ke phaello e phahameng ho hapa mehloli ea 'maraka. , Lik'hamphani tse ling tsa graphitization ea electrode ea graphite li fetohetse ho graphitization ea electrode e mpe. Ho phahamisoa ha lintlha tse peli ho lebisitse khaello ea hajoale ea mehloli ea graphitization 'marakeng oa electrode ea graphite le ho phahama ha litheko tsa graphitization. Hona joale, theko ea graphitization ea li-electrode tse ling tsa graphite e nyolohetse ho 4700-4800 yuan/ton, 'me tse ling li fihlile ho 5000 yuan/ton.
Ho phaella moo, dikhamphani dibakeng tse ding di fumane ditsebiso tsa dithibelo tsa tlhahiso nakong ya sehla sa ho futhumatsa. Ntle le ho etsa di-graphitization, ho besa le ditshebetso tse ding le tsona di thibetswe. Ho lebelletswe hore ditjeo tsa dikhamphani tse ding tsa di-electrode tsa graphite tse se nang sete e felletseng ya ditshebetso di tla eketseha.
3. Tlhoko ea 'maraka ea li-electrode tsa graphite e tsitsitse ebile ea ntlafala
Li-mold tsa tšepe tsa graphite electrode tse theohelang tlase li hloka feela ho busa
Haufinyane tjena, difeme tsa tshepe tse theohelang tlase tsa dielektrode tsa graphite di ela hloko haholo phokotso ya matla a mmaraka wa dielektrode tsa graphite, empa difeme tsa tshepe di ntse di na le tlhahiso e fokolang le matla a motlakase, mme difeme tsa tshepe ha di sebetse hantle, mme ho ntse ho na le maikutlo a ho leta le ho bona theko ya dielektrode tsa graphite.
Mabapi le tšepe ea sebōpi sa motlakase, libaka tse ling li lokisitse phokotso ea motlakase ea "boholo bo lekanang bohle" kapa phokotso ea carbon ea "mofuta oa motsamao". Hona joale, lifeme tse ling tsa tšepe ea sebōpi sa motlakase li qalile tlhahiso hape kapa li ka hlahisa liphetoho tse phahameng. Sekhahla sa ts'ebetso ea lifeme tsa tšepe ea sebōpi sa motlakase se eketsehile hanyane, e leng se molemo bakeng sa lifeme tsa tšepe ea sebōpi sa motlakase. Tlhoko ea electrode ea graphite.
Ho lebeletsoe hore 'maraka oa li-electrode tsa graphite o romelloe kantle ho naha o eketsehe
Kamora Letsatsi la Naha, ho ya ka dikhamphani tse ding tsa di-electrode tsa graphite, mmaraka ka kakaretso wa thepa e romellwang kantle ho naha o tsitsitse, mme dipotso tsa thepa e romellwang kantle ho naha di eketsehile, empa kgwebo ya sebele ha e a eketseha haholo, mme tlhoko ya di-electrode tsa graphite e tsitsitse.
Leha ho le jwalo, ho tlalehilwe hore sekgahla sa thepa ya dikepe tse romelang di-electrode tsa graphite se theohile morao tjena, mme tse ding tsa di-stock tse setseng koung di ka romelwa. Ka lebaka la keketseho e kgolo ya thepa ya lewatle selemong sena, dikhamphani tse ding tsa di-electrode tsa graphite di boletse hore ditjeo tsa thepa di ne di ikarabella bakeng sa hoo e ka bang 20% ya ditjeo tsa thepa ya kantle ho naha tsa di-electrode tsa graphite, e leng se ileng sa etsa hore dikhamphani tse ding tsa di-electrode tsa graphite di fetohele thekisong ya lehae kapa thomellong dinaheng tse haufi. Ka hona, ho theoha ha ditheko tsa thepa ya lewatle ho molemo bakeng sa dikhamphani tsa di-electrode tsa graphite ho eketsa thepa e romelwang kantle ho naha.
Ho phaella moo, qeto ea ho qetela ea ho thibela ho lahla thepa ea Yuropa e se e kentsoe tšebetsong 'me e tla beha ka molao mesebetsi ea ho thibela ho lahla thepa ea China ho tloha ka la 1 Pherekhong 2022. Ka hona, lik'hamphani tsa mose ho maoatle li ka ba le li-stock tse itseng kotara ea bone, 'me ho romelloa ha li-electrode tsa graphite kantle ho naha ho ka eketseha.
Tebello ea 'maraka: Tšusumetso ea phokotso ea matla e tla atoloha butle-butle, 'me lithibelo tsa tlhahiso le tšireletso ea tikoloho ea hoetla le mariha le litlhoko tsa tikoloho tsa Liolimpiki tsa Mariha li tla beoa holim'a tsona. Moeli oa tlhahiso ea 'maraka oa electrode ea graphite o ka tsoela pele ho fihlela ka Hlakubele 2022. Phepelo ea 'maraka oa electrode ea graphite e lebelletsoe ho tsoela pele ho fokotseha, 'me theko ea li-electrode tsa graphite e tla tsoela pele. Phahamisa litebello.
