Kuva mu mpera za Gicurasi kugeza mu ntangiriro za Kamena, hazatangizwa gahunda nshya yo kuvugurura ibiciro ku isoko rya needle coke. Ariko, ubu, isoko rya needle coke riyobowe n'imyumvire yo gutegereza no kureba. Uretse ibigo bimwe na bimwe bivugurura igiciro muri Kamena bigafata iya mbere mu kuzamura amayuni 300 kuri toni, amasezerano nyayo ntaragera aho ahagarara. Ni gute igiciro cy'isoko rya needle coke mu Bushinwa cyakwitwara muri Kamena, kandi gishobora gukomeza kwiyongera muri Gicurasi?
Ukurikije uko ibiciro bya needle coke bigenda bizamuka, bigaragara ko igiciro cya needle coke gihagaze neza kandi kikazamuka kuva muri Werurwe kugeza muri Mata, hanyuma kigakomeza kuzamuka nyuma yo kuzamuka mu ntangiriro za Gicurasi. Muri Gicurasi, igiciro rusange cya needle coke gishingiye kuri peteroli ni yuan 10.500-11.200/toni, icya coke gishingiye kuri peteroli ni yuan 14.000-15.000/toni, icya coke gishingiye ku makara ni yuan 9.000-10.000/toni, naho icya coke gishingiye ku makara ni yuan 12.200/toni. Kuri ubu, hari impamvu nyinshi zituma needle coke itegereza ikabona:
1. Igiciro cya peteroli ya coke ifite sulfure nke cyaragabanutse. Mu mpera za Gicurasi, igiciro cya coke isanzwe ifite sulfure nke muri Dagang na Taizhou cyafashe iya mbere, hanyuma Jinzhou Petrochemical irakurikiraho. Ku ya 1 Kamena, igiciro cya Jinxi Petrochemical cyaragabanutse kigera kuri yuan 6.900 kuri toni, kandi itandukaniro ry'ibiciro hagati ya coke ya peteroli ya Daqing na Fushun nziza ryariyongereye rigera kuri yuan 2.000 kuri toni. Kubera kugabanuka kwa coke ya peteroli ya sulfure nke, bimwe mu bigo byo mu gace k'uburasirazuba byongereye igipimo cyo kuvanga coke ya peteroli, byagize ingaruka ku busabe bwa coke ya needle ku rugero runaka. Inganda za needle coke zigomba kuvuga ku giciro cya coke ya peteroli muri Daqing na Fushun. Kuri ubu, nta gitutu kiri mu migabane yombi, kandi nta gahunda yo kugabanya igabanuka, bityo isoko rya needle coke rizategereza rikareba.
2. Ubusabe bwo kugura electrode mbi bugabanuka. Bitewe n’icyorezo, amadosiye y’amashanyarazi na bateri za digitale yagabanutse muri Gicurasi. Ibikoresho fatizo bya needle coke by’ibikoresho bya anode byatunganyijwe cyane cyane mu ntangiriro, kandi umubare w’amadosiye mashya waragabanutse. Ibigo bimwe na bimwe, cyane cyane ikoreshwa mu mashanyarazi, byongereye ububiko bwabyo.
3. Umusaruro wa electrode ya grafiti wakomeje kuba muto. Inyungu y’inganda zikora ibyuma ni nke, kandi ibigo bikora electrode ya grafiti bigizweho ingaruka n’icyorezo, kurengera ibidukikije n’ibiciro biri hejuru by’ibikoresho fatizo, bityo ishyaka ryabo ryo gutangira kubaka ntiriri hejuru kandi umusaruro wabo ni muto. Kubwibyo, ingano ya needle coke ni ntoya. Amwe mu masosiyete mato akorera mu nganda akoresha peteroli nkeya aho gukoresha needle coke.
Isesengura ry’uko isoko rihagaze: Mu gihe gito, ibigo by’ubucuruzi bya anode ahanini bicukura ibikoresho fatizo mu ntangiriro, kandi bigasinya amabwiriza mashya make. Byongeye kandi, igiciro cy’ibiro bya peteroli bya coke ifite sulfur nkeya kizagira ingaruka ku kohereza kwa needle coke. Ariko, ibigo by’ubucuruzi bya needle coke bifite ibiciro biri hejuru by’umusaruro, kandi birashoboka ko igiciro kizagabanuka ku nyungu. Kubwibyo, isoko rya needle coke rizakomeza kuzamuka muri Kamena mu gihe cyo gutegereza no kureba. Mu gihe kirekire, bitewe n’icyorezo i Shanghai n’ahandi hantu hagenzurwa, umusaruro w’imodoka witezwe kugaruka buhoro buhoro, kandi icyifuzo cya nyuma cyitezwe kwiyongera. Byongeye kandi, mu gihembwe cya gatatu, ibikoresho bimwe na bimwe bya electrode mbi bizakomeza gushyirwa mu musaruro, bizongera ubushake bw’ibikoresho fatizo bya needle coke. Iyo ibigo by’ubucuruzi bya electrode mbi bitangiye kuzuza ibikoresho fatizo, ikibazo cya needle coke kizongera gutera inkunga ibiciro.
