Ndi mitundu iti ya anodizing yomwe imagwiritsidwa ntchitombiri ya aluminiyamu?

Mfundo yaikulu ya Anodizing a aluminiyamu mbiri ndi kudzera electrochemical anachita, koma pali mitundu ingapo ya anodizing.

Pali njira zitatu zofala: oxalic acid, sulfuric acid ndi chromic acid.Njira izi anodizing ali ndi makhalidwe awo.LeroRuiqifeng New Materialadzakupatsani chidule chachidule cha mitundu yosiyanasiyana ya anodizing yomwe imagwiritsidwa ntchito pa mbiri ya aluminiyamu.

1. Njira ya sulfuric acid, yomwe iyenera kukhala njira wamba ya anodic oxidation ya mbiri ya aluminiyamu, filimu ya okusayidi yopangidwa ndi njira iyi ndi yopanda utoto komanso yowonekera, ndipo imakhala ndi mayamwidwe abwino amtundu, omwe ndi oyenera kutulutsa utoto.Mapangidwe a electrolyte ndi osavuta komanso okhazikika, osavuta kugwiritsa ntchito, komanso chofunika kwambiri, mtengo wake ndi wotsika.

2. Njira ya Oxalic acid: makulidwe a filimu ya oxide yomwe imapangidwa motere ndi yokwera kwambiri, ndipo idzabweretsa mitundu yokongoletsera.Komabe, njira imeneyi ndi yokwera mtengo ndipo imafuna mphamvu zambiri zamagetsi.

3. Chromic acid anodizing filimu ndi woonda kuposa sulfuric acid anodizing filimu, ndipo ndi woyera kapena imvi, amene ali ngati zotsatira za kupopera mbewu mankhwalawa pamwamba.Koma chromic acid oxidation siyenera kukongoletsa utoto.Komanso, hexavalent chromium mu chromic acid solution ndi poizoni kwambiri, ndipo mtengo woyankhira ndi mtengo wokonza ndi wokwera, kotero njirayi sigwiritsidwa ntchito mochepera.

4. Palinso njira yatsopano ya okosijeni ku Japan - sulfuric acid-oxalic acid oxidation njira, yomwe imatenga ubwino wa njira ziwirizi ndikukhala njira yaikulu ya okosijeni ku Japan.
