8.28-9.1 Ntibisanzwe Isi Isubiramo
Ibiteganijwe ku isoko ryinshi, icyizere ku masosiyete akomeye, hamwe n’impungenge zihishe ku bijyanye n’ubukungu byatumye leta ishaka kuzamuka, kuba ingorabahizi, gushaka gusubira inyuma, no kudashaka kubikora ku isoko ridasanzwe ry’isi muri iki cyumweru (8.28-9.1 ).
Icyambere, mu ntangiriro yicyumweru ,.isi idasanzweisoko ryakomeje kuzamuka mu mpera zicyumweru gishize. Bitewe nubushakashatsi buke buturuka mu bigo binini, inganda zitandukanya n’amasosiyete y’ubucuruzi byatangiye kugerageza kwirukana amagambo menshi. Gutwarwa numubare muto winyongera yinyongera, igiciro cyapraseodymium neodymium oxydeyongeye kugeragezwa kuri 505000 yuan / toni. Nyuma yaho, inganda zicyuma zakomeje kwiyongera, kandi amagambo yatanzwe ninganda za praseodymium neodymium guhera kuri 620000 yuan / toni yongeye kugaragara. Nkaho isoko ryasubukuwe mu cyumweru gishize, ku wa kabiri, amasosiyete y’ubucuruzi yatangiye kongera ibicuruzwa byayo no gutanga kugabanuka. Umuvuduko wa "pragmatique" woherejwe wakurikiyeho, ariko gutandukanya inganda n’ibyuma byarabujijwe kandi biharanira inyungu z’ibiciro, bituma igabanuka ry’imikorere y’isoko muri iki cyumweru. Amasosiyete yo hepfo muri rusange yari ategereje-kureba-no kwitonda mugihe ategereje igiciro cyurutonde rwubutaka budasanzwe bwamajyaruguru mu mpera zukwezi.
Icya kabiri, kubera ibicuruzwa byoherezwa mu mahanga by'agateganyo ku birombe byo muri Miyanimari na politiki yo kurengera ibidukikije mu karere ka Longnan, imyumvire ya dysprosium na terbium yazamutse. Mu ntangiriro z'icyumweru, cyayobowe na praseodymium na neodymium, bituma habaho icyarimwe icyarimwe haba ibiciro ndetse n’ibiciro by’ubucuruzi. Icyakurikiyeho, kubera ihungabana ry’ibicuruzwa bihanitse hamwe n’ingorabahizi mu kubona isoko ry’ibicuruzwa bihendutse, kimwe n’amagambo menshi hamwe no kubuza kohereza ibicuruzwa biva mu nganda zitandukanya, dysprosium n’ibicuruzwa bya terbium byahagaze neza kandi byiyongera gato mu bucuruzi.
Hanyuma, icyerekezo cyagadolinium, holmium, naerbiumiki cyumweru cyabaye gitangaje. Bitewe nibicuruzwa bikuru, ibiciro bya oxyde ya gadolinium, holmium, na erbium byakomeje kwiyongera, kandi ibisobanuro bya politiki muri rusange byemeza ko kugabanuka kwibiciro byahantu bizaba bisanzwe mugihe gito. Kubwibyo, izamuka ryibiciro ryihuta cyane, hamweerbium oxydekuzamuka cyane. Icyakora, iperereza ryakozwe na fer ya gadolinium na fer ya holmium ryerekana kandi ko gutumiza ibikoresho bya magneti bitigeze bitera imbere rwose, bigatuma inganda zibyuma zikibanda kubibazo bito, amasoko make, hamwe n’inyungu zoherezwa.
Kumva bigoye kumanuka no kugora kuzamuka. Guhera ku gicamunsi cyo ku ya 17, hamwe n’ubushakashatsi buke kuri dysprosium na terbium biva mu nganda zikoresha ibikoresho bya magnetiki, imyifatire y’isoko yarakomeje, kandi abaguzi barabikurikiza. Urwego rwohejuru rwa dysprosium na terbium rwashyushye vuba isoko. Mu ntangiriro ziki cyumweru, nyuma yigiciro kinini cyapraseodymium neodymium oxydeyageze kuri 504000 yuan / toni, yasubiye inyuma agera kuri 490000 / toni kubera ibihe by'ubukonje. Ikwirakwizwa rya dysprosium na terbium risa na praseodymium na neodymium, ariko bakomeje gushakisha no kuzamuka mu masoko atandukanye, bigatuma bigorana kongera ibyifuzo. Kubera iyo mpamvu, igiciro cyibicuruzwa bya dysprosium na terbium byashizeho ibihe biri hejuru ntibishobora kuba bike, kandi kubera icyizere gikomeye cyuko inganda ziteganya zahabu, ifeza, na icumi, ntibashaka kugurisha, bikaba bigenda byiyongera bigaragara mugihe gito.
Dushubije amaso inyuma muri iki cyumweru, hari ibintu bikurikira:
1.Ibiciro bya praseodymium na neodymium birahagaze neza kandi birakomeye, kuburyo bigoye gucuruza kubiciro buke. Ihame ryigiciro cyimbere-cyanyuma kiragaragara.
2. Mu ntangiriro zicyumweru, inzira yo gukurura, kureba hagati yicyumweru, no kongera gukora ubushakashatsi muri wikendi biragaragara cyane, ariko kubaza hasi nibiciro biri hasi bikomeza kuba ijwi nyamukuru.
3. Ibicuruzwa byo munsi ya magnetiki yamashanyarazi afite ibyangombwa bisabwa kubiciro, ingano, nigihe cyo gutanga amasoko.
4. Ibintu bidahindagurika imbere yimbere yumurongo winganda bigenda byoroha buhoro buhoro: inganda zitandukanya imyanda zikora cyane mukugabanya ibiciro no gutegura amasoko; Hagati y’izamuka ry’ibiciro by’amabuye y’ibanze, amasosiyete atandukanya ubutare mbisi yitonda mu bucukuzi no kuzuza; Inganda zibyuma zitanga ibiciro kuripraseodymium neodymiumnaicyuma cya dysprosiumgufata ishuri ryisumbuye no kugabanya ibiciro; Isosiyete ikora ibintu bya magnetique yongereyeho gato amagambo yavuzwe haba muburyo bukomeye kandi bushya kubikoresho bya magneti. Birumvikana ko igitekerezo cyo guhana umwanya kubiciro kugirango ugabanye hangovers gikunzwe cyane kumpande zose zinganda.
5. Uruhande rwamakuru rukomeje kuba isoko nyamukuru yumutima wigihe gito. Dysprosium na terbium byibasiwe cyane namakuru muri iki cyumweru, ibiciro bizamuka vuba.
6. Ibivugwa kuri gadolinium, holmium, na erbium birerekana cyane, hamwe nibicuruzwa byibanda cyane hamwe no kuzamuka gake kubiciro byubucuruzi. Ibigo byubucuruzi birabaza byimazeyo ibyateganijwe, ariko gutanga ibicuruzwa bikiri hasi biracyari bibi.
Guhera kuri uyu wa gatanu, ibiciro byuruhererekane rwibicuruzwa ni: 498000 kugeza 503000 yuan / toni yapraseodymium neodymium oxyde; Metal praseodymium neodymium610000 Yuan / toni;Neodymium oxydeni 505-501000 yuan / toni, hamwe nicyumaneodymiumni 62-630000 Yuan / toni; Dysprosium oxyde miliyoni 2.49-2.51 Yuan / toni; Miliyoni 2,4-2.43 yuan / toni yaicyuma cya dysprosium; Miliyoni 8.05-8.15 yuan / toni yaokiside; TerbiumMiliyoni 10-10.2 Yuan / toni; 298-30200 Yuan / toni yaokiside ya gadolinium; 280000 kugeza 290000 Yuan / toni yagadolinium icyuma; 62-630000 Yuan / toni yaokiside; Holmium icyumaigura ibihumbi 63-635 Yuan / toni.
Muri rusange, ibintu biriho ubu byo gupiganira ibicuruzwa bya praseodymium neodymium byaragabanutse, kandi umuvuduko w’amabuye y'agaciro na okiside y’imyanda urakabije. Mu mezi abiri yo koroshya inzira yo kuzamuka, kubara kumpera zose zurwego rwinganda ntibihagije. Ahari, mugihe kizaza, nubwo gahunda yisoko izakomeza kwiganjemo abaguzi, amaherezo izagaruka kubagurisha. Duhereye kuri macro, icyiciro gishya cya politiki yo gukangura kiri munzira, kandi Nzeri izaba idirishya ryingenzi mugushira mubikorwa politiki, yaba imitungo itimukanwa cyangwa politiki yinguzanyo. Urebye kuri microscopique, urebye ihindagurika rya vuba rya praseodymium na neodymium, igabanuka rya okiside ryakomeje kugabanuka, kandi ingufu za kinetic zigenda ziyongera cyane. Kubireba ejo hazaza, nubwo praseodymium neodymium ireba isoko cyane ugereranije na dysprosium na terbium, ibigo byambere byerekana uburyo bwo kuyobora, kandi ibiciro byo hejuru bizakomeza guhagarara neza cyangwa kurushaho kwiyongera. Kubutaka buciriritse kandi buremereye cyane nka dysprosium na terbium, ukurikije imiterere namakuru agezweho, haracyari umwanya wo gukura.
