Needle coke rudzi rwemhando yepamusoro rwakagadzirwa nesimba muzvinhu zvekabhoni. Chitarisiko chayo chakasimba chine maburi ane sirivha grey uye simbi inopenya. Chimiro chayo chine magadzirirwo anooneka ekuyerera, ine maburi makuru asi mashoma uye chimiro cheoval zvishoma. Ndiyo midziyo yekugadzira zvigadzirwa zvekabhoni zvepamusoro-soro zvakaita se ultra-high power electrode, zvinhu zvekabhoni zvakakosha, kabhoni fiber nezvimwe zvinhu zvayo zvakasanganiswa.
Zvichienderana nezvinhu zvakasiyana-siyana zvekugadzira, neelement coke inogona kukamurwa kuita mhando mbiri dze needle coke dzinotevedzana nemafuta uye coal series. Neelement coke inogadzirwa nepetroleum residue sezvinhu zvisina kugadzirwa iineelement coke dzinotevedzana nemafuta. Coal inoyera neelement coke inogadzirwa kubva mucoal tar pitch uye chikamu chayo chinonzi coal measure needle coke.
Ma indekisi anokanganisa kunaka kwe needle coke anosanganisira true density, sulfur content, nitrogen content, volatile content, ash content, thermal expansion coefficient, electrical resistivity, vibration-solid density, nezvimwewo. Nekuda kwemhando dzakasiyana dze index coefficients, needle coefficients dzinogona kukamurwa kuita super grade (superior grade), first grade nesecond grade.
Musiyano wekushanda pakati pechipimo chemarasha che needle coke nechipimo chemafuta che needle coke unosanganisira zvinotevera.
1. Mumamiriro ezvinhu akafanana, graphite electrode yakagadzirwa ne oil series needle coke iri nyore kugadzirwa kupfuura coal series needle coke maererano nekushanda kwayo.
2. Mushure mekunge zvigadzirwa zvegrafiti zvagadzirwa, zvigadzirwa zvegrafiti zveoil series needle coke zvine huremu hwakanyanya uye simba kupfuura zvecoal series needle coke, izvo zvinokonzerwa nekuwedzera kwecoal series needle coke panguva yegraphitization.
3. Mukushandiswa kwakananga kwe graphite electrode, zvigadzirwa zve graphitized zvine oil needle coke zvine coefficient yakaderera yekuwedzera kwekupisa.
4. Panyaya yezviratidzo zve graphite electrode, simba rekushandisa graphite products dze oil series needle coke rakakwirira zvishoma pane re coal series needle coke products.
5. Chinhu chinonyanya kukosha ndechekuti coke yemarasha inoyera needle coke inowedzera kana graphitization yekupisa kwakanyanya, kana tembiricha yasvika 1500-2000 ℃, saka kumhanya kwekupisa kunofanirwa kudzorwa zvakanyanya, kwete kupisa nekukurumidza, zvakanaka kusashandisa series graphitization process production, coke yemarasha inoyera nekuwedzera zvimwe zvinhu kudzora kuwedzera kwayo, kuwedzera kunogona kuderedzwa. Asi zvakaoma kuwana coke yemarasha yakavakirwa pamafuta.
6. Sisitimu yemafuta ane calcium ine huwandu hudiki hwecoke uye saizi yetsanga yakapfava, nepo tsono yekuyera marasha ine huwandu hushoma hwecoke uye saizi yetsanga yakakura (35-40 mm), izvo zvinogona kusangana nehukuru hwetsanga hunodiwa, asi zvinounza kuoma pakupwanya kwemushandisi.
7. Sekureva kweJapan Petroleum Coke Company, zvinofungidzirwa kuti musanganiswa weoil series needle coke uri nyore kupfuura wecoal series needle coke, saka zviri nyore kudzora panguva yekubika.
Kubva pamaonero ari pamusoro apa, oil system needle coke ine mana akaderera: low specific gravity, low strength, low specific resistance, maviri ekutanga akaderera pazvigadzirwa zvegrafiti, maviri ekupedzisira akaderera pazvigadzirwa zvegrafiti akanaka. Kazhinji, performance indexes ye oil series needle coke iri nani pane ye coal series needle coke, uye application inoda mari yakawanda.
Parizvino, graphite electrode ndiyo inonyanya kudiwa ne needle coke, ichipa 60% yekushandiswa kwe needle coke, uye mabhizinesi e electrode ane kudiwa kwakajeka kwe needle coke, pasina kudiwa kwemhando yepamusoro. Zvinhu zve lithium ion battery anode zvine kudiwa kwakasiyana-siyana kwe needle coke, musika wedhijitari wepamusoro unosarudza coke yakabikwa nemafuta, musika wemagetsi ebhatiri unonyanya kutsamira pa coke mbishi inodhura zvishoma.
Kugadzirwa kwe needle coke kune mwero wehunyanzvi, saka kune mabhizinesi mashoma emuno. Parizvino, vagadziri vema needle coke emafuta emuno vanosanganisira Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei New Energy, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, nezvimwewo. Vagadziri vakuru ve coal measure needle coke ndiBaowu Carbon Material, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Group, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri New Energy, Taiyuan Shengxu, nezvimwewo.
