ʻO kekahi mau pilikia a me ke kuhikuhi hoʻomohala o ka mākeke pauka graphite

ʻO ka hoʻopuka ʻana ografitima Kina, ʻo ia ka mea kiʻekiʻe loa ma ka honua. I ka makahiki 2020, e hana ana ʻo Kina i 650,000 tone o ka graphite kūlohelohe, e helu ana i 62% o ka huina honua. Akā, ke kū nei hoʻi ka ʻoihana pauka graphite o Kina i kekahi mau pilikia. E hoʻolauna ka graphite Furuite iā ʻoe i nā kikoʻī:

ʻO ka mea mua, ʻo ka hapa nui o nā ʻoihana hana ʻeli a me ka hana ʻana i ka graphite ma Kina aia i loko o kahi "nāwaliwali liʻiliʻi i hoʻopuehu ʻia", me ka hoʻomohala haunaele a me ka hoʻomohala predatory e kū nei, ka hoʻonele nui ʻana i nā kumuwaiwai mineral a me ka hoʻohana haʻahaʻa. ʻO ka lua o ka pilikia, ʻo nā huahana graphite maoli o Kina he mau huahana mua, a he haʻahaʻa ka waiwai i hoʻohui ʻia o nā huahana graphite, a hilinaʻi nui nā huahana kiʻekiʻe i nā mea lawe mai. ʻO ke kolu, ʻo ke kaumaha o nā palena o ke kaiapuni, a ua hoʻoikaika ʻia ka hana ʻana o ka pauka graphite e ka kaohi ʻana i ke kaiapuni. ʻO nā kaʻina hana ʻeli, holoi a me ka hoʻomaʻemaʻe o ka pauka graphite maoli he maʻalahi ke hana i ka lepo, luku i nā mea kanu a hoʻohaumia i ka lepo a me ka wai, ʻoiai ʻo ka hopehana ʻanaʻO nā ʻano hana o nā ʻoihana graphite ma Kina e alakaʻi ai i nā pilikia palekana o ke kaiapuni. ʻO ka hā, ke kaomi o nā kumukūʻai hana, he ʻoihana hana nui ka hana ʻeli pōhaku Kina, a ʻoi aku ka nui o nā kumukūʻai hana ma mua o 10% o ka huina o nā kumukūʻai hana. I nā makahiki i hala iho nei, ua piʻi koke ke kumukūʻai hana ma Kina. ʻO ka lima, ke lilo nei ke kumukūʻai o ka ikehu i mea hiki ʻole ke hoʻomanawanui no nā ʻoihana graphite.
Pauka graphiteHe ʻoihana hoʻopau ikehu nui ka hana ʻana, a ʻo ke kumukūʻai uila ma kahi o 1/4. Me ka piʻi ʻana o nā kaʻa ikehu hou, ua lilo nā mea anode o nā pila lithium i ke kuhikuhi noi nui loa o ka graphite. Ua hoʻopukapuka pū kekahi mau ʻoihana kūloko nui i nā papahana hana hohonu o ka flake graphite, a ua ulu ka flake graphite i nā huahana waiwai nui; I ka manawa like, ke wikiwiki nei ka hoʻohui ʻana o nā kumuwaiwai mineral kūloko, a e hoʻohuli ʻia nā kumuwaiwai kiʻekiʻe o ka ʻoihana graphite i nā ʻoihana hana nui a me ka waena; ʻO ka piʻi nui ʻana o ke koi o ka ʻoihana pauka graphite e hoʻolaha hou aku i ka ulu ʻana o nā lawe mai graphite, a e hoʻokele pū i ka hoʻonohonoho hou ʻana o ka kūloko.graphite ʻāpanamākeke.
