Kodi mungapewe bwanji aluminium dzimbiri?

Aluminiyamu yosasamalidwa imakhala ndi dzimbiri yabwino kwambiri m'malo ambiri, koma m'malo a asidi kapena amchere, aluminiyamu nthawi zambiri amawononga mwachangu.Nawu mndandanda wa momwe mungapewere zovuta za aluminium corrosion.

Akagwiritsidwa ntchito moyenera, aluminiyamu amakhala ndi moyo wautali kuposa zida zina zambiri zomangira, kuphatikiza chitsulo cha carbon, galvanized steel ndi mkuwa.Kukhalitsa kwake ndikwabwino kwambiri.Zimakhalanso zapamwamba kuposa zida zina zomwe zimakhala ndi sulfure kwambiri komanso m'madzi.

Mitundu yodziwika kwambiri ya dzimbiri ndi:

• Galvanic dzimbiri zikhoza kuchitika pamene pali zonse zitsulo kukhudzana ndi electrolytic mlatho pakati pa zitsulo zosiyanasiyana.
• Pitting dzimbiri kumachitika pamaso pa electrolyte (mwina madzi kapena chinyezi) munasungunuka mchere, kawirikawiri chlorides.
• Kuwonongeka kwa mpata kumachitika m'ming'alu yopapatiza, yodzaza ndi madzi.

Ndiye mungatani kuti mupewe zimenezi?

Nawu mndandanda wanga wamomwe mungapewere dzimbiri:

• Ganizirani kapangidwe kambiri.Mapangidwe a mbiriyo ayenera kulimbikitsa kuyanika - ngalande zabwino, kupewa dzimbiri.Muyenera kupewa kukhala ndi aluminiyamu yosatetezedwa yokhudzana ndi madzi osasunthika, ndipo pewani matumba omwe litsiro lingatolere ndikusunga zinthuzo monyowa kwa nthawi yayitali.
• Samalani ma pH.Makhalidwe a pH otsika kuposa 4 ndi apamwamba kuposa 9 ayenera kupewedwa kuti atetezedwe ku dzimbiri.
• Samalani ndi chilengedwe:M'malo ovuta kwambiri, makamaka omwe ali ndi chloride wochuluka, chidwi chiyenera kuperekedwa ku chiopsezo cha galvanic dzimbiri.M'madera oterowo, njira ina yotsekera pakati pa aluminiyamu ndi zitsulo zolemekezeka kwambiri, monga mkuwa kapena zitsulo zosapanga dzimbiri, zimalimbikitsidwa.
• Kuwonongeka kumawonjezeka ndi kuyimirira:M'makina otsekedwa, okhala ndi madzi, pomwe madzi amakhala osasunthika kwa nthawi yayitali, dzimbiri zimawonjezeka.Ma inhibitors amatha kugwiritsidwa ntchito nthawi zambiri kuti ateteze dzimbiri.
• Pewanisnthawi zonse, zonyowa.Moyenera, sungani aluminiyumu youma.Chitetezo cha cathodic chiyenera kuganiziridwa m'malo ovuta, onyowa kuti asawonongeke.
