Kuv puas tuaj yeem siv Gr1 Titanium Tubing hauv Hydrochloric Acid?
Apr 09, 2024
Gr1 titanium yuav hnov mob maj mam nrog dilute hydrochloric acid, tab sis thaum lub sij hawm cov tshuaj tiv thaiv nws yuav maj mam tsim ib oxidized zaj duab xis uas tiv thaiv titanium hlau, yog li txo cov tshuaj tiv thaiv kom nres.
Lwm yam ntxwv ntawm titanium yog corrosion kuj, yog vim nws affinity rau oxygen yog tshwj xeeb tshaj yog loj, muaj peev xwm tsim ib txheej ntawm ntom oxide zaj duab xis rau nws nto, yuav tiv thaiv titanium los ntawm nruab nrab corrosion. titanium hlau tuaj yeem tsim cov purified oxide zaj duab xis ntawm nws qhov chaw nyob rau hauv feem ntau aqueous daws.
Yog li ntawd, titanium nyob rau hauv acidic, alkaline, nruab nrab saline tov thiab oxidizing xov xwm nrog zoo stability, dua li cov uas twb muaj lawm stainless hlau thiab lwm yam non-ferrous hlau corrosion kuj yog zoo, thiab txawm piv rau platinum. Txawm li cas los xij, yog tias nyob rau hauv ib qho nruab nrab, tuaj yeem txuas ntxiv yaj cov oxide zaj duab xis rau saum npoo ntawm titanium, ces titanium hauv qhov nruab nrab no yuav corroded.
Piv txwv li, titanium hauv hydrofluoric acid, concentrated los yog kub hydrochloric acid, sulfuric acid thiab phosphoric acid, vim hais tias cov kev daws teeb meem no dissolves titanium nto oxide zaj duab xis, yog li titanium corroded. Yog tias tus neeg sawv cev oxidizing lossis qee cov hlau ions tau ntxiv rau cov kev daws teeb meem no, cov oxide zaj duab xis ntawm titanium tiv thaiv, thiab kev ruaj ntseg ntawm titanium nce.
