Nekuchera matope pasi pegungwa, Japan inogona here kurega kuvimba kwayo nezviwanikwa zveChina zvisingawanzoonekwi?

Pakati paNdira 2026, Japan yakatumira chikepe chesainzi chekuchera mvura che "Chikyu" kuSouth Bird Island iri kure muPacific Ocean kuti iite "chirongwa chekutanga chekubvisa mvura isina kujeka pasi rose". Shi Xuefa, muongorori paFirst Institute of Oceanography yeMinistry of Natural Resources uye director weKey Laboratory of Marine Geology and Mineralization yeMinitary Resources, akataura mupepa rake kuti China ndiyo nyika yakakura pasi rose panyaya yevhu, kugadzirwa, kushandiswa uye kutengeswa kwezviwanikwa zvenyika isina kujeka. Kuwanikwa kwezviwanikwa zvenyika isina kujeka pasi pegungwa kunopa dambudziko kune chinzvimbo cheChina senyika huru ine zviwanikwa zvenyika isina kujeka pasi pevhu.

Mari yekudzosa nekutakura ivhu remadhaka, pamwe nezvinodiwa zvehunyanzvi kuti zvibudirire pakukura kukuru, inyaya dzakaomawo. Sezvo basa iri richida kudzosa ivhu kubva pasi pegungwa uye riri kure nenyika, mari yekufambisa inoenderana ichawedzerawo. Pamusoro pezvo, pane musiyano pakati pevhu remadhaka remadhaka remadhaka remadhaka remadhaka rakacherwa pasi pegungwa nezvinhu zvakacherwa panyika, uye matekinoroji ekuchenesa anoenderana haasati agadzirwa zvizere. Nekuda kwehunhu hwemakemikari hwakafanana hwezvinhu gumi nenomwe zvemadhaka, kupatsanurwa nekugadziriswa kunoda kemikari yepamusoro uye chaiyo. Semuenzaniso, matanho angangoita mazana maviri anodiwa kupatsanura zvinhu zvinodiwa uchishandisa solvent extraction.

Semuenzaniso, oxide lanthanum (Lanthanum Oxide, chemical formula La₂O₃, CAS: 1312-81-8) inogadzirwa neWONAIXI imhando huru ye rare earth oxide muzvinhu zvitsva zve rare earth. Nekuda kwehunhu hwayo hwe optical, catalytic uye electrical, yave chinhu chakakosha mukugadzira zvinhu zvepamusoro uye matekinoroji emiganhu. Mumakore achangopfuura, nekukura nekukurumidza kwesimba idzva, ruzivo rwemagetsi uye indasitiri dzekuchengetedza zvakatipoteredza, huwandu hwekushandiswa kweoxide lanthanum hwakaramba huchiwedzera, zvichiratidza kugona kukuru kwemusika uye kukosha kwetekinoroji. Parizvino, WONAIXI yakawana kugadzirwa kukuru kwe high-purity oxide lanthanum kuburikidza nematekinoroji epamusoro akadai sematekinoroji akasiyana-siyana epatenti, kutsigira zviratidzo zvakagadzirwa uye kukurudzira kuwedzera kwecheni yeindasitiri kubva pakutorwa kwezviwanikwa kusvika kune zvigadzirwa zvine kukosha kwakanyanya.

Japan ndeimwe yenyika dzinoshanda zvakanyanya mumigodhi yepasi rose yekuchera pasi pegungwa. Zvisinei, Japan inotarisanawo nematambudziko akawanda mukushandiswa kwehurongwa hwayo hwezvicherwa. China yakagadzira indasitiri ye rare earth yakakura mumakumi mashoma emakore, ichiunganidza hwaro hwakadzama hwehunyanzvi uye ine mutengo wakakwira wezvigadzirwa. Izvi hazviitike kamwe kamwe. Tichifunga kuti kugona kwepasi rose kuchenesa nekugadzira rare earth kwakanyanya muChina, kunyangwe Japan ikakwanisa kuchera zvinhu zvitsva, icharamba ichivimba zvakanyanya nemasisitimu ekugadzira ekunze.
