ʻO Kina Neodymium Magnet Situation a me Prospect

He mea nui ka ʻenehana waiwai paʻa mau a Kina i ka honua. ʻAʻole nui nā ʻoihana e hana i ka hana a me ka noi, akā ʻo ka hana noiʻi kekahi i ka ascendant. Mahele nui ʻia nā mea Mākēneki paʻa i ka Mākēneki honua laha ʻole, Mākēneki paʻa paʻa, ʻume mākenēki paʻa paʻa a Ferite Mākēneki paʻa. I waena o lākou, he mea hoʻohana ākea ka magnet magnet Neodymium honua āpau a me ka wikiwiki e hoʻomohala ʻana i ka huahana magnet.

1. Lawe ʻo Kina i nā pono o ka honua Neodymium paʻa pinepine.
ʻO Kina ka mea hana nui o nā minelala honua kakaʻikahi, e helu ana no 62.9% o ka huina nui o nā huahana mineral honua i ʻike ʻia ma ka makahiki 2019, a ukali ʻia e ʻAmelika Hui Pū ʻIa a me ʻAukekulia, no 12.4% a me 10% pakahi. Mahalo i nā mālama honua laha ʻole, ua lilo ʻo Kina i kahua hoʻokumu nui loa o ka honua a me ka waihona hoʻolilo o nā mākēneki honua ʻike ʻole ʻia. Wahi a nā helu helu o Kina Rare Honua ʻoihana ʻĀina, i ka makahiki 2018, ua hana ʻo Kina i 138000 mau tona o nā mākēneka Neodymium, no 87% o ka huina huahana o ka honua, kokoke he 10 mau manawa ma Iapana, ka lua o ka nui ma ka honua.

2. Hoʻohana ākea ka nui o nā mākēneka Neodymium nunui i ka honua.
Mai ke kuanaʻike o nā kahua noi, hoʻohana pinepine ʻia ka magnet Neodymium haʻahaʻa i ka adsorption ʻume mākenēki, hoʻokaʻawale ʻume mākenēki, paikikala uila, pahu ukana, puka kīwī, mea pāʻani a me nā kula ʻē aʻe, ʻoiai hoʻohana nui ʻia ka magnet Neodymium kiʻekiʻe i nā ʻano uila. nā motika, e like me ka moto hoʻōla ikehu, kaʻa kaʻa, hanauna mana makani, pono hana kiʻi leo mua, ka mīkini hoʻokiʻekiʻe, a pēlā aku.

3. Piʻi mau nā mea Neodymium o Kina me ka piʻi mau.
Mai ka makahiki 2000, ua lilo ʻo Kina i mea hana nui loa o ka honua ʻo nā magnet Neodymium rare o ka honua. Me ka hoʻomohala ʻana o nā noi o lalo, ke ulu wikiwiki nei nā huahana o NdFeB manamana ma Kina. Wahi a ka ʻike o ka hui ʻoihana hana honua ʻo China Rare Honua ma 2019, ʻo ka hopena o nā blangko Neodymium sinter he 170000 tona, e helu ana no 94.3% o ka huina huahana o Neodymium magnetic mau mea i kēlā makahiki, ʻo NdFeB i hoʻopaʻa ʻia no 4.4%, a me nā huina huahana ʻē aʻe. helu ʻia no 1.3% wale nō.

4. Kuhi ʻia ka neodymium magnet China e piʻi mau i luna.
Hoʻolālā ʻia ka hānai honua o NdFeB i ka ʻoihana kaʻa, kaʻaahi a me ke kaʻaahi, robot lopako, hanauna mana makani a me nā kaʻa ikehu hou. ʻO ka ulu o nā ʻoihana i luna i nā makahiki ʻelima e hiki mai ana ma mua o 10%, kahi e alakaʻi ai i ka hoʻonui ʻana o ka hana Neodymium ma Kina. Ua manaʻo ʻia ʻo ka hoʻopuka o Neodymium magnet ma Kina e mālama i ka ulu o 6% i nā makahiki ʻelima e hiki mai ana, a ʻoi aku ka nui ma mua o 260000 tonnes e 2025.

5. Koi ʻia nā mea kiʻekiʻe e hana ʻia e nā mea magnet pinepine honua e ulu.
Hoʻohana ākea ka hoʻohana ʻia ʻana o nā mākēneki honua laha ʻole i nā kahua hoʻokele waiwai haʻahaʻa-kalapona, e like me ka mālama ʻana i ka ikehu a me ka ʻoihana pale hana kaiapuni. E like me nā ʻāina a puni ka honua e hoʻopukapuka nui i ka haʻahaʻa-kalapona, ka mālama ʻana i ka ikehu a me ka pale ʻana i nā huahana ʻōmaʻomaʻo a paipai i nā huahana ʻōmaʻomaʻo, hoʻopukapuka nui nā ʻāina i ka haʻahaʻa-carbon, ka mālama ʻana i ka ikehu a me ka pale ʻana i nā hana hana kaiaola a hoʻolaha i nā huahana ʻōmaʻomaʻo nā ʻoihana e kū mai nei e like me nā kaʻa ikehu hou, nā robots hanauna o ka makani a me ka hana akamai, e ulu ana ka makemake no nā hana kiʻekiʻe he laha ʻole o ka honua. Me ka ulu wikiwiki ʻana o nā ʻoihana e kū nei, e ulu ka makemake no ka hana kiʻekiʻe kiʻekiʻe o ka honua āpau.
