Precious Hlau Cr nrog corrosion kuj
Kev piav qhia
Chromium hmoov yog siv dav siv hlau hmoov uas pom cov ntawv thov hauv ntau qhov kev lag luam.Nws yog tsim los ntawm kev txo cov chromium oxide nrog txhuas hmoov nyob rau hauv lub qhov cub kub, uas ua rau ib tug nplua, tsaus grey hmoov nrog siab purity.
Ib qho ntawm cov khoom tseem ceeb tshaj plaws ntawm chromium hmoov yog nws zoo heev corrosion kuj.Nws yog dav siv nyob rau hauv zus tau tej cov stainless hlau thiab high-temperature alloys rau aerospace thiab automotive industries.Chromium's corrosion-resistant zog pab ua rau kom lub durability thiab lifespan ntawm cov alloys, ua rau lawv zoo tagnrho rau siv nyob rau hauv hnyav ib puag ncig.
Sib nrug los ntawm nws siv nyob rau hauv zus tau tej cov hlau alloys, chromium hmoov kuj yog siv raws li ib tug pigment nyob rau hauv zus tau tej cov xim, inks, thiab dyes.Qhov loj me me ntawm chromium hmoov ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim cov hlau zoo nkauj tiav.Cov kev ua tiav no muab cov txheej txheem ruaj khov, tiv taus corrosion nrog lub siab ci, ua rau lawv tsim nyog siv rau ntau yam kev siv, suav nrog kev lag luam tsheb thiab aerospace.
Chromium hmoov kuj tseem siv rau hauv kev tsim khoom ntawm lwm cov ntaub ntawv, xws li nickel-chromium alloys, uas yog siv dav hauv kev tsim cov khoom cua sov.Cov alloys no zoo tagnrho rau siv nyob rau hauv high-kub daim ntaub ntawv, ua tsaug rau lawv cov ntsiab lus melting siab thiab corrosion kuj.
Hauv cov ntsiab lus, chromium hmoov yog cov khoom siv ntau yam nrog cov khoom zoo corrosion kuj.Nws yog dav siv nyob rau hauv zus tau tej cov stainless hlau, high-temperature alloys, thiab metallic finishes.Nws cov khoom ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv nyob rau hauv ib puag ncig hnyav thiab kev siv kub kub, ua rau nws yog ib qho khoom siv nrov hauv ntau yam lag luam.
