Menene nau'ikan anodizing daban-daban da ake amfani da sualuminum profiles?
ByRuiqifeng Sabon Kayaat www.aluminum-artist.com
Babban ka'idar Anodizing na bayanan martaba na aluminum shine ta hanyar amsawar electrochemical, amma akwai nau'ikan anodizing da yawa.
Akwai hanyoyin gama gari guda uku: oxalic acid, sulfuric acid da chromic acid.Wadannan hanyoyin anodizing suna da nasu halaye.YauRuiqifeng Sabon Kayazai ba ku taƙaitaccen gabatarwa na nau'ikan anodizing daban-daban da ake amfani da su akan bayanan martaba na aluminum.
1. Sulfuric acid Hanyar, wanda ya kamata ya zama na kowa hanya domin anodic hadawan abu da iskar shaka na aluminum profiles, da oxide fim kafa ta wannan hanya ne colorless kuma m, kuma yana da kyau launi sha yi, wanda ya dace da hadawan abu da iskar shaka canza launi.Abubuwan da ke tattare da electrolyte yana da sauƙi kuma barga, mai sauƙin aiki, kuma mafi mahimmanci, farashin yana da ƙananan ƙananan.
2. Hanyar Oxalic acid: kauri na fim din oxide da aka samar ta wannan hanya yana da girma, kuma zai kawo wasu launuka na ado.Duk da haka, wannan hanya yana da tsada kuma yana buƙatar babban adadin makamashin lantarki.
3. Chromic acid anodizing film ne siririn fiye da sulfuric acid anodizing film, kuma shi ne kashe fari ko launin toka, wanda shi ne kamar sakamakon surface spraying.Amma oxidation chromic acid bai dace da canza launi ba.Bugu da ƙari, chromium hexavalent a cikin maganin chromic acid yana da guba sosai, kuma farashin maganin da farashin sarrafawa yana da yawa, don haka wannan hanya ba ta da amfani.
4. Har ila yau, akwai sabuwar hanyar oxidation a Japan - hanyar sulfuric acid-oxalic acid oxidation, wanda ke shayar da amfanin hanyoyin guda biyu kuma ya zama babban hanyar oxidation a Japan.
