Zokonda zimasintha, anthu ena amakhala osangalala pomwe ena amakhala achisoni.
WoodMac akuyembekeza kuti kukonzanso chikhulupiriro kudzatenga nthawi, ndipo ma voliyumu azamalonda sangathe kuyambiranso nthawi yomweyo. "Ziwerengero zonse zamitengo yazinthu zomwe zakhudzidwa zidzawunikidwa kwambiri." Pakadali pano, Fitch Solutions Country Risk and Industry Research idati mitengo ya faifi tambala ikukwera komanso mitengo yopangira batire ikukwera, ogula ma nickel apamwamba amafunafuna Njira Zina zoperekedwa ndi Russia.
Dziko la Russia ndi limene likutsogola pogulitsa miyala ya nickel ya Gulu 1, pamene dziko la China ndilofunika kwambiri pamakampani oyenga. Fitch adanena mu lipoti lake latsopano kuti opanga magalimoto, opanga mabatire ndi ogula mafakitale akuyenera kupanga mgwirizano watsopano wamabizinesi kuti apeze njira zina za nickel zapamwamba, monga momwe zinthu zaku Russia zimavutikira polimbana ndi mkangano waku Russia ndi Ukraine. oletsedwabe. Kuti izi zitheke, Gulu la China Tsingshan ndi makampani ena akukulitsa luso loyenga la nickel otsika adzapindula.
Fitch adawonanso kuti kusintha kokonda kwa omwe akutumiza kunja, zilango komanso kufuna kuchepetsa chiwopsezo cha zilango kukukhudza kugula kwa nickel yaku Russia. Choncho, ntchito zamigodi ndi zoyenga m'mayiko "otetezeka" omwe ali ndi malamulo okhazikika komanso oyendetsa malonda angapindule.Pakali pano, anodic makutidwe ndi okosijeni wa titaniyamu ndi titaniyamu aloyi makamaka ikuchitika mu acidic njira. Mtundu, makulidwe ndi magwiridwe antchito a filimu ya oxide yomwe idalandira ndi yosiyana kutengera yankho la anodizing ndi momwe zinthu ziliri.
Njira zazikulu ndi oxalic acid anodizing, kugunda anodizing, wandiweyani filimu anodizing, ndi mtundu anodizing. Pamene anodized filimu ya titaniyamu ndi titaniyamu aloyi akulephera kukwaniritsa zofunika, kumaphatikizapo kuchotsa anodized filimu titaniyamu ndi titaniyamu aloyi. Izi ndi zoyambira za anodizing wakuda:
Mtundu wa titaniyamu siwothandiza pakupanga, komanso uli ndi luso linalake. Pansi pamikhalidwe yoyenera ya anodic gasification, filimu yowoneka bwino ya oxide yomwe imapangidwa pamwamba pa titaniyamu, yomwe imakhala yosavuta kupanga mtundu wosokoneza, idzatulutsa mtundu wolemera kwambiri waluso. zotheka ntchito.
Pamene panopa akudutsa titaniyamu anode inaimitsidwa mu electrolyte, mpweya kwaiye pa titaniyamu anode amachitira ndi titaniyamu kupanga okusayidi filimu, makulidwe ake ukuwonjezeka ndi kuwonjezeka voteji, ndipo nthawi yomweyo, cholepheretsa zotsatira. filimu ya okusayidi pa panopa imawonjezekanso. . Magetsi ena amafanana ndi makulidwe ena a filimu ya okusayidi, ndipo mtundu wa filimu ya oxide umasintha ndi makulidwe a filimu ya okusayidi.
