Kev nyiam hloov, qee tus neeg zoo siab thiab qee tus neeg nyuaj siab.
WoodMac cia siab tias kev txhim kho kev ntseeg siab yuav siv sijhawm, thiab cov khoom lag luam tsis zoo li yuav rov qab los sai sai. "Txhua tus nqi ntsuas ntawm cov khoom lag luam cuam tshuam yuav raug tshuaj xyuas ntxiv." Lub caij no, Fitch Solutions Lub Tebchaws Risk thiab Kev Tshawb Fawb Kev Lag Luam tau hais tias raws li tus nqi npib tsib xee nce thiab cov nqi roj teeb tsim tau nce siab, cov neeg siv khoom qib siab nickel nrhiav lwm txoj hauv kev muab los ntawm Russia.
Russia yog lub chaw muag khoom ntawm Qeb 1 nickel ore, thaum Tuam Tshoj yog tus tseem ceeb tshaj plaws hauv kev lag luam refining. Fitch tau hais hauv nws daim ntawv tshaj tawm tshiab tias cov neeg tsim tsheb, cov neeg tsim khoom siv roj teeb thiab cov neeg siv khoom lag luam zoo li yuav tsim kev sib koom ua lag luam tshiab los tsim cov khoom siv nickel qib siab, raws li cov khoom siv los ntawm Russia tawm tsam cov keeb kwm yav dhau los ntawm Russia-Ukraine tsis sib haum xeeb. tseem txwv. Txog qhov kawg no, Tuam Tshoj Tsingshan Group thiab lwm lub tuam txhab nquag tsim cov qib qis nickel refining peev yuav tau txais txiaj ntsig.
Fitch kuj tau sau tseg tias kev hloov pauv cov kev nyiam ntawm cov neeg siv khoom, kev rau txim thiab kev xav kom txo qis kev nplua yuav cuam tshuam rau kev yuav khoom ntawm Lavxias teb sab nickel exports. Yog li ntawd, kev ua lag luam mining thiab refining nyob rau hauv "kev nyab xeeb" lub teb chaws nrog ntau ruaj khov kev tswj hwm thiab kev lag luam tswj yuav tau txais txiaj ntsig.Tam sim no, anodic oxidation ntawm titanium thiab titanium alloys yog tsuas yog nqa tawm hauv cov kua qaub. Cov xim, thickness thiab kev ua tau zoo ntawm cov oxide zaj duab xis tau sib txawv nyob ntawm qhov kev daws teeb meem anodizing thiab txheej txheem txheej txheem.
Cov txheej txheem tseem ceeb yog oxalic acid anodizing, pulse anodizing, tuab zaj duab xis anodizing, thiab xim anodizing. Thaum cov yeeb yaj kiab anodized ntawm titanium thiab titanium alloys tsis ua raws li qhov yuav tsum tau ua, nws tseem yuav raug tshem tawm cov yeeb yaj kiab anodized ntawm titanium thiab titanium alloys. Cov hauv qab no yog kev taw qhia rau xim anodizing:
Cov xim ntawm titanium nto tsis yog tsuas yog muaj txiaj ntsig zoo hauv kev tsim khoom, tab sis kuj muaj qee yam khoom muaj nqis. Raws li qhov tsim nyog anodic gasification tej yam kev mob, pob tshab oxide zaj duab xis tsim nyob rau saum npoo ntawm titanium, uas yog ib qho yooj yim los tsim kev cuam tshuam xim, yuav tsim ib tug xim nplua nuj nyob rau hauv artistic tus nqi. muaj peev xwm siv tau.
Thaum cov tam sim no dhau los ntawm titanium anode raug tshem tawm hauv cov electrolyte, cov pa oxygen generated ntawm titanium anode reacts nrog titanium los ua oxide zaj duab xis, lub thickness ntawm uas nce nrog qhov nce ntawm qhov voltage, thiab nyob rau tib lub sij hawm, cuam tshuam cov nyhuv. ntawm oxide zaj duab xis ntawm tam sim no kuj nce. . Qee qhov hluav taws xob sib raug rau qee qhov tuab ntawm oxide zaj duab xis, thiab xim ntawm oxide zaj duab xis hloov nrog lub thickness ntawm oxide zaj duab xis.
