Neodymium oxide (Nd₂O₃)ali ndi ntchito zofunika paukadaulo wobiriwira, makamaka muzinthu izi:
1. Munda wazinthu zobiriwira
High-ntchito maginito zipangizo: Neodymium okusayidi ndi kiyi zopangira zopangira mkulu-ntchito NdFeB okhazikika maginito zipangizo. NdFeB okhazikika maginito zipangizo ndi ubwino wa mankhwala mkulu maginito mphamvu ndi coercivity mkulu, ndipo chimagwiritsidwa ntchito magalimoto magetsi, m'badwo mphamvu mphepo, zida zamagetsi ndi madera ena. Zida za maginito zokhazikika izi zakhala ndi gawo lofunikira pakuwongolera mphamvu zamagetsi komanso kuchepetsa kugwiritsa ntchito mphamvu, ndipo ndi chimodzi mwazinthu zofunika kwambiri paukadaulo wamagetsi obiriwira.
Matayala obiriwira: Neodymium oxide amagwiritsidwa ntchito popanga mphira wa butadiene wopangidwa ndi neodymium, womwe umakhala wolimba kwambiri komanso wosasunthika ndipo ungagwiritsidwe ntchito kupanga "matayala obiriwira". Kugwiritsa ntchito matayala oterowo kumatha kuchepetsa kuwononga mafuta komanso kutulutsa mpweya wamagalimoto, ndikuwongolera chitetezo komanso kulimba kwa matayala.
2. Ntchito zoteteza chilengedwe
Kuyeretsa utsi wagalimoto: Neodymium oxide ikhoza kugwiritsidwa ntchito kupanga zopangira zoyeretsera utsi wamagalimoto. Zinthu zapadziko lapansi zomwe sizipezeka muzothandizira zimatha kuchepetsa kutulutsa kwa zinthu zovulaza (monga carbon monoxide, nitrogen oxides ndi ma hydrocarbons) mu gasi wopopa, potero kuchepetsa kuipitsidwa kwa chilengedwe.
Mphamvu zongowonjezwdwa: M'magawo opangira mphamvu yamphepo ndi mphamvu ya dzuwa, zida za maginito zokhazikika zopangidwa ndi neodymium oxide zimagwiritsidwa ntchito m'majenereta ndi ma mota, zomwe zimathandizira kutembenuka kwamphamvu komanso kulimbikitsa kugwiritsa ntchito mphamvu zongowonjezwdwa.
3. Ukadaulo wokonzekera wobiriwira
Njira yobwezeretsanso zinyalala ya NdFeB: Iyi ndi njira yobiriwira komanso yosamalira zachilengedwe yokonzekera neodymium oxide. Neodymium oxide imapezedwanso ku zinyalala za neodymium iron boron kudzera munjira monga kuyeretsa, kusefera, mpweya, kutentha ndi kuyeretsa. Njirayi sikuti imangochepetsa migodi ya ore yoyamba, komanso imachepetsa kugwiritsa ntchito mphamvu komanso kuwononga chilengedwe popanga.
Njira ya Sol-gel: Njira yokonzekera iyi imatha kuphatikizira kuyeretsa kwambiri kwa neodymium oxide pamtunda wocheperako, kuchepetsa kugwiritsa ntchito mphamvu komanso kutulutsa mpweya wa kaboni chifukwa cha kuwotcha kwambiri.
4. Ntchito zina zobiriwira
Utoto wa Ceramic ndi Magalasi: Neodymium oxide imatha kugwiritsidwa ntchito kupanga utoto wa ceramic ndi magalasi kuti apange zobiriwira za ceramic ndi magalasi okhala ndi luso lapamwamba kwambiri. Zidazi zimagwiritsidwa ntchito kwambiri pomanga ndi kukongoletsa, ndipo njira yopangira zinthu imakhala yogwirizana ndi chilengedwe.
Zida za laser: Neodymium oxide ikhoza kugwiritsidwa ntchito popanga zida za laser, zomwe zimagwiritsidwa ntchito kwambiri muzachipatala, kukonza mafakitale ndi madera ena ndipo ndizogwirizana ndi chilengedwe.
Kusintha kwa msika ndi machitidwe amtengo wa neodymium oxide
Mphamvu zamsika
Perekani:
Kukula kwa ntchito zapakhomo: Motsogozedwa ndi kufunikira kwa msika, mabizinesi ambiri apakhomo a praseodymium-neodymium oxide awonjezera kuchuluka kwa magwiridwe antchito, ndipo mabizinesi ena akugwira ntchito mokwanira. Mu February 2025, kutulutsa kwa praseodymium-neodymium oxide kudakwera ndi 7% mwezi-pa-mwezi. Akuti mu 2025, zotulutsa za dziko langa za praseodymium-neodymium oxide zidzawonjezeka ndi matani 20,000-30,000, ndipo zotsatira zake zidzafika matani 120,000-140,000.
Ziletso zochokera kumayiko ena: Kuchokera mu Okutobala mpaka Disembala 2024, chifukwa cha kutsekedwa kwa nkhondo yapachiweniweni ku Myanmar, kuchuluka kwa nthaka zomwe zidatumizidwa kuchokera ku Myanmar zidapitilirabe kutsika, ndipo kuchulukira kwa miyala yochokera kunja sikunachepe.
Kufuna:
Motsogozedwa ndi minda yomwe ikubwera: Monga zida zopangira maginito a neodymium iron boron okhazikika, praseodymium-neodymium oxide imayendetsedwa ndi chitukuko cha minda yomwe ikubwera monga maloboti a humanoid ndi AI, ndipo kufunikira kwake kukupitilira kutulutsidwa.
Kufuna kwamakampani apansi panthaka ndikovomerezeka: Tikatengera momwe zinthu zidachitikira mu February 2025, ngakhale makampani opanga maginito nthawi zambiri amasiya kupanga patchuthi cha Chikondwerero cha Spring, amawonjezera kuchuluka kwa magwiridwe antchito pakatha Chaka Chatsopano, makamaka kuthamangira kukapereka katundu. Ngakhale pali kugula ndi kusunga Chaka Chatsopano chisanafike, kuchuluka kwake kuli kochepa, ndipo pakufunikabe kugula pambuyo pa Chaka Chatsopano.
Makhalidwe a ndondomeko: Pamene ndondomeko zoyendetsera makampani zikuchulukirachulukira, mphamvu yobwerera m'mbuyo ya praseodymium-neodymium oxide imachotsedwa pang'onopang'ono, ndipo msika ukupitiriza kusonkhana kumakampani omwe ali ndi ubwino waukadaulo ndi masikelo. M'tsogolomu, msika wa praseodymium-neodymium oxide ukuyembekezeka kuwonjezeka kwambiri.
Mitengo yamitengo
Mtengo waposachedwa: Pa Marichi 25, 2025, mtengo wofananira wa neodymium oxide mu Sino-Foreign Exchange unali RMB 472,500/ton; pa March 21, 2025, Shanghai Nonferrous Network anasonyeza kuti mtengo osiyanasiyana okusayidi neodymium anali RMB 454,000-460,000/tani, ndi mtengo avareji RMB 457,000/tani.
Kusintha kwamitengo:
Kukwera mu 2025: Pambuyo pa Chikondwerero cha Spring mu 2025, mtengo wa praseodymium-neodymium oxide unakwera kuchokera ku RMB 400,000 / tani chikondwerero chisanachitike kufika ku RMB 460,000 / ton, ndikuyika kukwera kwatsopano m'zaka zitatu zapitazi. Mu Januwale-February 2025, mtengo wapakati wa neodymium oxide unali RMB 429,778/tani, kukwera 4.24% pachaka.
Kugwa mu 2024: Mu 2024, mtengo wonse wa neodymium oxide udawonetsa kutsika kotsika. Mwachitsanzo, mtengo wa neodymium oxide wa Northern Rare Earth mu Marichi 2024 unali RMB 374,000/tani, kutsika ndi 9.49% kuyambira February.
Mtsogolomu: Potengera kukwera kwakukulu kwa mtengo wa praseodymium-neodymium oxide koyambirira kwa 2025, mtengo wa neodymium oxide ukhoza kukhala wokwera pakanthawi kochepa. Komabe, m’kupita kwa nthaŵi, pamakhalabe zosatsimikizirika m’zinthu monga mmene chuma chapadziko lonse chikuyendera, kusintha kwa ndondomeko, ndi kapezedwe kake ndi kufunikira kwa msika, ndipo mkhalidwe wamitengo umafunika kuunikiranso.
