I-Flake graphite iyiminerali engavuselelwa engavuseleleki, esetshenziswa kabanzi embonini yanamuhla futhi iyinsiza ebalulekile yamasu. I-European Union efakwe ohlwini lwe-graphene, umkhiqizo osuqediwe wokucubungula ama-graphite, njengephrojekthi entsha yezobuchwepheshe be-Flagship ngokuzayo, futhi i-graphite esohlwini njengenye yezinhlobo eziyi-14 "zokufa kwamaminerali. I-United States ibala izinsiza ze-flake graphite njengezinto ezibalulekile zamaminerali zokwenziwa kwezimboni eziphezulu zobuchwepheshe. I-graphite yaseChina igcina i-akhawunti yama-70% omhlaba, futhi iyindawo yokugcina ye-graphite enkulu futhi ethumela ngaphandle emhlabeni. Kodwa-ke, kunezinkinga eziningi kwinqubo yokukhiqiza, enjengokungcola kwezimayini, izinga eliphansi lokusebenzisa izinsiza kanye nomonakalo omkhulu wemvelo. Ukushoda kwezinsizakusebenza kanye nezindleko zangaphandle zemvelo azibonisi inani langempela. Izinkinga ezilandelayo zokwabelana zabahleli bezithombe ze-furuite graphite zibonakaliswa ikakhulukazi ezicini ezilandelayo:
Okokuqala, intela yezinsizakusebenza idinga ukulungiswa ngokuphuthumayo. Izinga lentela eliphansi: Intela yamanje ye-Graphite yamanje yi-3 yuan ngethani ngalinye, elikhanya kakhulu futhi alibonisi ukuswelakala kwezinsizakusebenza kanye nezindleko zangaphandle zemvelo. Uma kuqhathaniswa nomhlaba ongavamile ngokuswelana okufanayo kwamaminerali nokubaluleka, ngemuva kokuguqulwa kwentela yomhlaba engavamile, hhayi kuphela izinto zentela ezifakwe ohlwini ngokwahlukana, kepha futhi nezinga lentela liphakanyiswa izikhathi ezingaphezu kwezingu-10. Ngokuqhathaniswa nokukhuluma, inani lentela yezinsizakusebenza ze-flake graphite liphansi. Inani lentela elilodwa Akunakwesayensi ukubala ngevolumu yokuthengisa: Kubalwa ngevolumu yokuthengisa, hhayi ngenani langempela lamaminerali ambiwe, ngaphandle kokubheka isinxephezelo somonakalo wezemvelo, ukuthuthukiswa kwezimali okunengqondo kwezinsizakusebenza, izindleko zokuthuthuka kanye nokuphekelwa kwezinsiza.
Okwesibili, ukuthekelisa kuqhutshwa kakhulu. I-China ngumkhiqizi omkhulu emhlabeni we-graphite yemvelo yemvelo futhi bekulokhu kungumthumeli omkhulu we-graphite yemikhiqizo yemvelo. Ngokuphikisana kakhulu nokuxhashazwa kwe-flake ngokweqile kwezinsizakusebenza ze-flake, amazwe athuthukile, aholela kubuchwepheshe bemikhiqizo yokucubungula okujulile, basebenzise isu 'lokuthenga esikhundleni sezokumbiwa phansi' nge-graphite yemvelo bese uvimba ubuchwepheshe. Njengemakethe enkulu kunazo zonke ye-graphite eChina, ukungeniswa kwe-Japan's account ngo-32.6% wama-excressions athunyelwa ngaphandle, kanye nengxenye yowakwa-ore ongenisiwe we-graphite ore acwila olwandle; Ngakolunye uhlangothi, iSouth Korea, yavala izimayini zayo ze-graphite futhi ingenise inani elikhulu lemikhiqizo ngamanani aphansi; Ivolumu yonyaka ye-United States i-Akhawunti ye-10.5% yevolumu yokuthumela kwelinye izwe laseChina, futhi izinsiza zalo ze-graphite zivikelwe ngumthetho.
Okwesithathu, ukucubungula kukhulu kakhulu. Izakhiwo zegrafu zihlobene kakhulu nosayizi wesikali sayo. Ubukhulu obuhlukahlukene be-flake graphite banokusetshenziswa okuhlukile, izindlela zokucubungula kanye nezinkundla zohlelo lokusebenza. Njengamanje, kunokuntuleka kocwaningo ngobuchwepheshe be-graphite ore ngezimpawu ezahlukahlukene eChina, kanye nokusatshalaliswa kwezinsizakusebenza ze-graphite ezinesikali esihlukile akukatholakali, futhi ayikho indlela ejulile yokucubungula. Izinga lokutakula lokuzuza kwe-graphite liphansi, futhi isivuno se-flake enkulu siphansi. Izici zomthombo azicacile, futhi indlela yokucubungula ayishadile. Ngenxa yalokhu, i-graphite enkulu ye-flake ayikwazi ukuvikeleka ngempumelelo futhi i-graphite encane ye-flake ayikwazi ukusetshenziswa ngempumelelo ngesikhathi sokucubungula, okuholela ekunciphiseni okukhulu kwezinsiza ezibalulekile zamasu amasu.
Okwesine, umehluko wentengo phakathi kokungenisa kanye nokuthekelisa kuyamangaza. Iningi lemikhiqizo ye-flake yemvelo ye-flake ekhiqizwa eChina yimikhiqizo eyinhloko ecubungulwa, futhi ucwaningo kanye nentuthuko kanye nokukhiqizwa kwemikhiqizo engezwe ngenani eliphakeme ngokusobala kuyantuleka. Thatha i-graphinerite ebumsulwa ephezulu njengesibonelo, amazwe aphesheya athatha ukuhola ku-graphiner amsulwa aphezulu ngezinzuzo zawo zobuchwepheshe, futhi avimbele izwe lethu ngemikhiqizo ephezulu yezobuchwepheshe. Njengamanje, ubuchwepheshe obuphakeme be-graphite obukhulu beChina ngeke bufinyelele ekuhlanzeni ngo-99.95%, futhi ubumsulwa bama-99.99% noma ngaphezulu bungancike ngokuphelele ekungenisweni. Ngo-2011, inani elijwayelekile le-flake ye-flake eChina lalingaba ngu-4,000 yuan / ton, ngenkathi intengo ye-99.99% engeniswe kusuka ku-graphiner punity punity / ithoni, futhi umehluko wentengo wawumangazayo.
