12.9 bawuti yamagalimoto amtundu wa phosphated

Ukadaulo wokutira pamwamba pa zomangira monga ma U-bolts nthawi zambiri amakhala ozizira ngati malata, omwe amatha kuyambitsa dzimbiri atagwiritsidwa ntchito kwazaka zopitilira 1.Kamodzi dzimbiri, sizidzangokhudza maonekedwe ndi maonekedwe, komanso zimakhudza ntchito Yake imakhudza kwambiri kugwiritsa ntchito zipangizo, kotero mu ntchito yathu, tiyenera kulabadira zinthu zotsatirazi kuti tipewe dzimbiri.
Choyamba, lolani pamwamba pa U-bolt youma momwe tingathere kuti tipewe zambiri.
1. Kuphatikizika kwa fumbi kapena tinthu tating'ono ting'onoting'ono tating'onoting'ono, mumlengalenga wonyezimira, zomangira zomangika zamadzi ndi zomangira zitsulo zosapanga dzimbiri, zimalumikiza ziwirizo mu batri yaying'ono, zomwe zimayambitsa machitidwe a electrochemical, ndipo filimu yoteteza imawonongeka mosavuta, yotchedwa electrochemical Analyze corrosion..
2. Chitsulo chosapanga dzimbiri cha U-bolt chimakhala ndi zomatira pamwamba pa madzi a organic, popanda madzi ndi mpweya kuti apange organic acid, organic acid ndi chiwonongeko chautali pamwamba pa zitsulo zachitsulo.
3. Kumamatira kwazitsulo zosapanga dzimbiri za U-bolts, alkali ndi malo okhala ndi mchere wambiri kumayambitsa dzimbiri m'deralo kwa ophunzira.
4. Mu mpweya wina woipitsidwa (monga mlengalenga ndi wolemera mu mitundu yambiri ya sulfides, carbon oxides, nitrogen oxides m'dziko langa), madzi osasunthika amapanga madzi a sulfuric acid, nitric acid, ndi acetic acid, zomwe zimayambitsa ophunzira. ku chemistry structural corrosion.
