8.28-9.1 Ndemanga ya Padziko Lapansi Pasabata
Zoyembekeza zamsika zapamwamba, chidaliro chamakampani otsogola, ndi nkhawa zobisika zokhuza chuma chapangitsa kuti pakhale mkhalidwe wofuna kuwuka, kukhala wovuta, wofuna kubwerera, komanso wosafuna kutero pamsika wosowa padziko lapansi sabata ino (8.28-9.1) ).
Choyamba, kumayambiriro kwa sabata, adziko losowamsika udapitilira zomwe zikuchitika kumapeto kwa sabata yatha. Poyendetsedwa ndi mafunso otsika kuchokera kumakampani akuluakulu, mafakitale olekanitsa ndi makampani ogulitsa adayamba kuyesa kuthamangitsa mawu apamwamba. Moyendetsedwa ndi pang'ono malamulo owonjezera, mtengo wapraseodymium neodymium okusayidiidayesedwanso pa 505000 yuan/ton. Pambuyo pake, mafakitale azitsulo adapitilira kukwera, ndipo mawu a mafakitale a praseodymium neodymium kuyambira 620000 yuan/ton adawonekeranso. Monga ngati msika udayambiranso sabata yatha, Lachiwiri, makampani ochita malonda adayamba kuonjeza zotumiza ndikupereka kuchotsera. Mayendedwe a "pragmatic" otumizira adatsatiranso, koma kulekanitsa ndi mafakitale azitsulo anali oletsedwa komanso osasunthika pamitengo yokhazikika, zomwe zinapangitsa kuti msika ukhale wochepa kwambiri sabata ino. Makampani apansi panthaka nthawi zambiri anali kudikirira-ndi-kuwona komanso kusamala podikirira mtengo wamndandanda wamayiko osowa kumpoto kumapeto kwa mwezi.
Kachiwiri, chifukwa cha zoletsa kwakanthawi kochepa pamigodi ku Myanmar komanso mfundo zoteteza chilengedwe m'chigawo cha Longnan, malingaliro a dysprosium ndi terbium akwera. Kumayambiriro kwa sabata, idayendetsedwa ndi praseodymium ndi neodymium, zomwe zimapangitsa kuti pakhale kuwonjezeka kwapanthawi yomweyo kwamitengo yamtengo wapatali komanso yogulitsa. Pambuyo pake, chifukwa cha kukhazikika kwa malonda amtengo wapatali komanso zovuta kupeza magwero otsika mtengo a katundu, komanso kutchulidwa kwakukulu ndi kuletsa kutumizidwa kuchokera ku zomera zolekanitsa, mankhwala a dysprosium ndi terbium akhazikika ndikuwonjezeka pang'ono pazochitikazo.
Pomaliza, azimuth agadolinium, holmium,ndierbiumsabata ino yakhala yamatsenga. Motsogozedwa ndi zinthu zodziwika bwino, mitengo ya oxide ya gadolinium, holmium, ndi erbium ikupitilira kukwera, ndipo kutanthauzira kwa mfundo kumakhulupirira kuti kutsika kwamitengo kudzakhala kwanthawi yayitali. Chifukwa chake, kuwonjezeka kwamitengo kumakhala mwachangu, ndierbium okusayidikuchuluka kwambiri. Komabe, kufunsa kwa gadolinium iron ndi holmium iron kukuwonetsanso kuti kuyitanitsa zida zamaginito sikunapite patsogolo, zomwe zidapangitsa kuti mafakitale azitsulo azingoyang'anabe mafunso otsika, kugula kochepa, komanso kutumiza kwa phindu.
Kumva movutikira kutsika komanso kuvutikira kukwera. Kuyambira masana a 17, ndi mafunso otsika a dysprosium ndi terbium kuchokera ku mafakitale apamwamba a maginito, malingaliro a msikawo adakhala osasinthasintha, ndipo ogula amatsatira mwakhama. Kuthamanga kwapamwamba kwa dysprosium ndi terbium kunatenthetsa msika mwachangu. Kumayambiriro kwa sabata ino, pambuyo pa mtengo wapamwamba wapraseodymium neodymium okusayidiinafika pa 504000 yuan/tani, idabwereranso ku 490000 yuan/tani chifukwa cha kuzizira. Mchitidwe wa dysprosium ndi terbium ndi wofanana ndi wa praseodymium ndi neodymium, koma akhala akufufuza nthawi zonse ndikukwera m'mabuku osiyanasiyana a nkhani, zomwe zimapangitsa kuti zikhale zovuta kuonjezera kufunika. Chotsatira chake, mtengo wa mankhwala a dysprosium ndi terbium wapanga mkhalidwe wamakono wapamwamba sungakhale wotsika, ndipo chifukwa cha chidaliro champhamvu muzoyembekeza zamakampani za golidi, siliva, ndi khumi, sakufuna kugulitsa, zomwe zikuchulukirachulukira. zowonekera mu nthawi yaifupi.
Tikayang'ana mmbuyo sabata ino, pali makhalidwe awa:
1. Mtengo wa praseodymium ndi neodymium ndi wokhazikika komanso wamphamvu, zomwe zimapangitsa kuti zikhale zovuta kugulitsa pamitengo yotsika. Kukhazikika kwa mtengo wakutsogolo kumakhala koonekeratu.
2. Kumayambiriro kwa sabata, chizolowezi chokoka, kuyang'ana pakati pa sabata, ndi kufufuza kachiwiri kumapeto kwa sabata ndizoonekeratu, koma mafunso otsika ndi mitengo yotsika amakhalabe liwu lalikulu.
3. Kutsika kwa maginito madongosolo ochuluka azinthu ali ndi zofunikira zomveka pamtengo, kuchuluka, ndi nthawi yogula.
4. Zinthu zokhotakhota kutsogolo kwa unyolo wa mafakitale zikuchepa pang'onopang'ono: mafakitale omwe amalekanitsa zinyalala akugwira ntchito kwambiri pakuchepetsa mitengo ndikukonzekera kugula; Pakati pa kukwera kwamitengo ya miyala yaiwisi yaiwisi, makampani olekanitsa miyala yaiwisi amakhala osamala pakukumba ndi kubwezeretsanso; Mafakitole azitsulo akupereka mitengo yakepraseodymium neodymiumndiDysprosium ironkuthandizira kusukulu yasekondale ndikuchepetsa kutsika mtengo; Makampani opanga maginito awonjezera pang'ono mawu awo m'maoda ovuta komanso atsopano azitsulo zamaginito. Zowonadi, lingaliro la kusinthanitsa nthawi kuti lichepetse kutsekeka limachitika ponseponse m'mbali zonse zamakampani.
5. Mbali ya nkhani imakhalabe gwero lalikulu la malingaliro amsika akanthawi kochepa. Dysprosium ndi terbium zinakhudzidwa kwambiri ndi nkhani sabata ino, ndi mitengo ikukwera mofulumira.
6. Kulingalira kwa gadolinium, holmium, ndi erbium ndi chidziwitso chapamwamba, ndi katundu wochuluka kwambiri komanso kuwonjezeka pang'ono kwa mitengo yamalonda. Mabizinesi akufunsa mwachangu za maoda, koma kubweretsa kutsika kudakali koyipa.
Pofika Lachisanu lino, mitengo yazinthu zosiyanasiyana ndi: 498000 mpaka 503000 yuan/ton ofpraseodymium neodymium okusayidi; Metal praseodymium neodymium610000 yuan/tani;Neodymium oxidendi 505-501000 yuan/tani, ndi zitsuloneodymiumndi 62-630000 yuan/ton; Dysprosium oxide 2.49-2.51 miliyoni yuan/tani; 2.4-2.43 miliyoni yuan/tani yaDysprosium iron; 8.05-8.15 miliyoni yuan/tani yaterbium oxide; Metal terbium10-10.2 miliyoni yuan/tani; 298-30200 yuan/tani wagadolinium oxide; 280000 mpaka 290000 yuan/tani yagadolinium chitsulo; 62-630000 yuan/tani yaholmium oxide; Holmium chitsulomtengo 63-635,000 yuan/ton.
Ponseponse, zomwe zikuchitika pano za kuyitanitsa kutumiza kwa praseodymium neodymium zatsika, ndipo kukakamiza kwa ore yaiwisi ndi zinyalala za oxides ndizovuta kwambiri. M'miyezi iwiri yochepetsera kukwera, kuwerengera kumapeto kwa bizinesi sikukwanira. Mwinamwake, m'tsogolomu, ngakhale kuti malonda a msika adzayang'aniridwa ndi ogula, pamapeto pake adzabwerera kwa ogulitsa. Kuchokera pamawonedwe akuluakulu, ndondomeko yatsopano yotsitsimutsa ili m'njira, ndipo September adzakhala zenera lofunika kwambiri pa kukhazikitsidwa kwa ndondomeko, kaya ndi nyumba kapena ndondomeko za ngongole. Kuchokera pamawonedwe ang'onoang'ono, poyang'ana kusinthasintha kwaposachedwa kwa praseodymium ndi neodymium, kuchepa kwa ma oxides kwakhala kukucheperachepera, ndipo mphamvu ya spiral m'mwamba ya kinetic yachuluka kwambiri. Pachiweruzo chamtsogolo, ngakhale praseodymium neodymium imakonda kwambiri msika poyerekeza ndi dysprosium ndi terbium, mabizinesi otsogola amawonetsa utsogoleri wawo, ndipo mitengo yokwera idzapitilirabe kukhazikika kapena kuwonjezerekanso. Pazinthu zapakatikati ndi zolemera zapadziko lapansi monga dysprosium ndi terbium, kutengera machitidwe ndi nkhani zamakono, pali malo oti akule.
