Dab tsi yog cov yam ntxwv ntawm tooj liab thiab tooj liab alloys

Bronze Ameslikas hais txogtooj liab alloysnrog tin ua lub ntsiab additive.Niaj hnub no, tag nrho cov tooj liab alloys tshwj tsis yog tooj dag suav nrog hauv qeb ntawm bronze, xws li tin bronze, aluminium bronze, thiab beryllium bronze.Nws tseem yog kev cai los faib bronze rau hauv ob pawg: tin bronze thiab Wuxi bronze.Nws yog tsuas yog siv los tsim cov corrosion-resistant thiab hnav-resistant qhov chaw, xws li lub tes tsho ncej, thrust bearing pads, thiab lwm yam. Vim yog cov peev txheej tsawg ntawm cov tin, qee cov khoom siv alloying tau dav siv hauv kev lag luam tsis ntev los no los hloov cov tin.Cov khoom siv ntau tshaj yog aluminium bronze, lead bronze thiab beryllium bronze.Aluminium bronze muaj kev tiv thaiv corrosion zoo dua li tin bronze, thiab feem ntau yog siv los tsim cov khoom tiv thaiv corrosion thiab hnav-tiv taus, xws li lub zog, worm gears, bushings, thiab lwm yam. Beryllium bronze feem ntau yog siv rau cov springs tseem ceeb thiab elastic qhov chaw, thiab. raws li hluav taws xob contactors, electrodes rau hluav taws xob vuam tshuab, moos thiab moos qhov chaw, thiab lwm yam.

Ntau txoj hauv kev tau siv los tiv thaiv tooj liab, qhov tseem ceeb tshaj plaws yog qhov kev vam meej hauv kev tshawb fawb thiab kev loj hlob siv ntau yam corrosion inhibitors.Tam sim no, Nyiv muaj ntau thiab ntau dua kev tshawb fawb ntawm tooj liab thiab tooj liab alloy nto tiv thaiv technology, tshwj xeeb tshaj yog nyob rau hauv nam ntawm lub tsev cov ntaub ntawv kho kom zoo nkauj, thiab tau ua tiav ntau yam kev vam meej.Kev ua haujlwm hauv tsev tsuas yog tsom mus rau qhov chaw polishing thiab kev kho cov xim ntawm cov khoom siv tooj liab, thiab qee qhov kev nce qib kuj tau ua.

Cov txheej txheem ntws ntawm tooj liab thiab tooj liab alloy nto passivation yog: degreasing - dej kub ntxuav - dej txias ntxuav - pickling (concentrated hydrochloric acid los yog loj feem ntawm 10%, chav tsev kub 30s) - tshuab ntxhua khaub ncaws - muaj zog acid ntxuav - dej ntxuav - nto txias (30-90g / LCrO3, 15-30g / LH2S04, 15-30s) -> ntxuav-pickling (112804 nrog ib pawg loj ntawm 10%)-> ntxuav-passivation-ntxuav- ziab.Tsis tsim nyog passivation films ntawm tooj liab thiab tooj liab alloys yuav raug tshem tawm los ntawm soaking nyob rau hauv H2S04 tov nrog ib tug kub loj feem ntawm 1,000, concentrated hydrochloric acid los yog 300g / L sodium hydroxide tov.
