Needle coke ine chimiro chakafanana netsono uye yakagadzirwa nemafuta anotsvedza anobva muzvicheneswa kana kuti coal tar pitch. Ndiyo chinhu chikuru chekugadzira ma electrode e graphite anoshandiswa mukugadzira simbi uchishandisa electric arc furnace (EAF). Kuongorora uku kwemusika we needle coke kunotarisa kutengeswa kubva kuindasitiri ye graphite, indasitiri yemabhatiri, nedzimwe. Kuongorora kwedu kunotarisawo kutengeswa kwe needle coke muAPAC, Europe, North America, South America, uye MEA. Muna 2018, chikamu cheindasitiri ye graphite chaive nemusika wakawanda, uye maitiro aya anotarisirwa kuenderera mberi munguva yekufungidzira. Zvinhu zvakaita sekuwedzera kwekudiwa kwema electrode e graphite enzira ye EAF yekugadzira simbi zvichatamba basa rakakosha muchikamu cheindasitiri ye graphite kuchengetedza chinzvimbo chayo mumusika. Zvakare, mushumo wedu wepasi rose wemusika we needle coke unotarisa zvinhu zvakaita sekuwedzera kwekugona kuchenesa mafuta, kuwedzera kwekushandiswa kwemotokari dzegirini, kuwedzera kudiwa kwema electrode e UHP graphite. Zvisinei, kuwedzera kwekusawirirana pakati pezvinodiwa ne lithium nekupa zvinhu kwakatarisana nekuunza mari muindasitiri yemarasha nekuda kwemitemo inorambidza kusvibiswa kwekabhoni, kuchinja kwemitengo yemafuta asina kucheneswa nemarasha zvinogona kukanganisa kukura kweindasitiri ye needle coke munguva yakatarwa.
Musika weGlobal Needle Coke: Pfupiso
Kuwedzera kwekudiwa kwema electrodes e UHP graphite
Ma electrode eGraphite anoshandiswa mukushandiswa, senge maovheni e arc akadzika pasi uye maovheni e ladle ekugadzira simbi, zvinhu zvisiri zvesimbi, uye simbi. Anonyanya kushandiswa muEAFs pakugadzira simbi. Ma electrode eGraphite anogona kugadzirwa uchishandisa petroleum coke kana needle coke. Ma electrode eGraphite akakamurwa kuita simba renguva dzose, simba guru, simba guru, uye UHP zvichibva pamatanho akadai se resistivity, electric conductivity, thermal conductivity, resistance to oxidation and thermal shock, uye mechanical strength. Pakati pemhando dzese dzema electrode eGraphite, ma UHP graphite electrodes ari kuwana kutariswa muindasitiri yesimbi. Kudiwa uku kwema UHP electrodes kuchatungamira mukuwedzera kwemusika wepasi rose we needle coke paCAGR ye6% munguva yekufanotaura.
Kubuda kwesimbi yegirini
Kuburitswa kweCO2 idambudziko guru riri kutariswa neindasitiri yesimbi pasi rese. Kuti dambudziko iri rigadziriswe, mabasa akawanda ekutsvaga nekusimudzira (R&D) akaitwa. Mabasa aya ekutsvaga nekusimudzira akaita kuti simbi yegirini ibude. Vaongorori vakawana nzira itsva yekugadzira simbi inogona kubvisa kuburitswa kweCO2 zvachose. Munzira yechinyakare yekugadzira simbi, panguva yekugadzira simbi, utsi hwakawanda, kabhoni, uye moto unopfuta zvinoburitswa. Maitiro echinyakare ekugadzira simbi anoburitsa CO2 kaviri kupfuura huremu hwesimbi. Zvisinei, nzira itsva iyi inogona kugadzira simbi isina kuburitswa. Tekinoroji yekubata nekuchengetedza marasha yakapwanywa uye kabhoni (CCS) ndeimwe yeiyi. Kubudirira uku kunotarisirwa kuve nemhedzisiro yakanaka pakukura kwemusika wese.
Nzvimbo Yemakwikwi
Nekuvapo kwevatambi vashoma vakuru, musika wepasi rose we needle coke wakanyanya kuwanda. Ongororo iyi yakasimba yevatengesi yakagadzirirwa kubatsira vatengi kuvandudza chinzvimbo chavo pamusika, uye zvinoenderana neizvi, mushumo uyu unopa ongororo yakadzama yevagadziri veneedle coke vanotungamira, vanosanganisira C-Chem Co. Ltd., GrafTech International Ltd., Mitsubishi Chemical Holdings Corp., Phillips 66 Co., Sojitz Corp., uye Sumitomo Corp.
Zvakare, mushumo wekuongorora musika we needle coke unosanganisira ruzivo nezvemafambiro nematambudziko ari kuuya achakanganisa kukura kwemusika. Izvi ndezvekubatsira makambani kuronga uye kushandisa mikana yese yekukura iri kuuya.
