O a ituaiga eseese o anodizing o loʻo faʻaaogaina i lugafa'ailoga alumini?

O le mataupu faavae o le Anodizing o tala'aga alumini e ala i le electrochemical reaction, ae e tele ituaiga o anodizing.
E tolu auala masani: oxalic acid, sulfuric acid ma chromic acid. O nei auala anodizing ei ai o latou lava uiga. O aso neiRuiqifeng Mea Fouo le a tuʻuina atu ia te oe se faʻamatalaga puupuu o ituaiga eseese o anodizing faʻaaogaina i luga o faʻamatalaga alumini.
1. Sulfuric acid metotia, lea e tatau ona avea ma auala masani mo anodic oxidation o talaaga otooto alumini, o le oxide ata tifaga faia i lenei auala e le lanu ma manino, ma e lelei le faatinoga absorption lanu, lea e talafeagai mo oxidation valivali. O le faʻaogaina o le electrolyte e faigofie ma mautu, faigofie ona faʻaogaina, ma sili atu ona taua, o le tau e maualalo.
2. Oxalic acid method: o le mafiafia o le oxide ata tifaga gaosia i lenei auala e fai si maualuga, ma o le a aumaia ai ni lanu teuteu. Ae ui i lea, o lenei metotia e taugata ma e manaʻomia ai le tele o le eletise.
3. Chromic acid anodizing ata e manifinifi nai lo sulfuric acid anodizing ata tifaga, ma e ese paʻepaʻe po o le efuefu, lea e pei o le aafiaga o luga spraying. Ae o le chromic acid oxidation e le talafeagai mo le valivali. E le gata i lea, o le hexavalent chromium i le chromic acid solution e sili ona oona, ma o le tau o le fofo ma le tau o le gaosiga e maualuga, o lea e le faʻaaogaina ai lenei metotia.
4. O loʻo i ai foʻi se auala fou faʻamaʻi i Iapani - sulfuric acid-oxalic acid oxidation method, lea e faʻaaogaina ai le lelei o auala e lua ma avea ma auala autu faʻamaʻi i Iapani.
