We did some research about how to strip the anodized aluminum. After several tests, we found that we can use stronger hydrofluoric acid, by which I mean, 5 part of HF into 20 part of water. But be careful when you dip the anodized aluminum. Daniel Herman S Suhendra, drs. -

Aluminum parts are particularly prone to chemical attack of the basis metal when stripping chem film or anodic coatings. Stripping solutions should not cause intergranular attack in excess of .0002" or end grain pitting greater than .001 (BAC 5771). if the free alkalinity and complexing agent in the solution are not under good
A. We have had some success using a mixture of phosphoric acid (35 mL/L), chromium trioxide (20 g/L) and water to strip Type I (chromic acid), Type II (sulfuric acid) and Type III (sulfuric acid/oxalic acid) anodize coatings from aluminum. The solution is heated to 100 C and usually takes less than 15 minutes to strip the anodize.
2) By incorporating chelating or complexing agents in the stripping solution that have a greater affinity for the metal being removed than for the base material. 3) By adding inhibitors to stripping processes to chemically or physically adsorb onto the substrate and rotect it

Oct 17, 2014.ABSTRACT. Aluminum corrosion is commonly encountered when performing chemical process operations involving surface finishing, predominantly in preparation for paint application. The protective oxide film of aluminum is only stable in a pH range of 4.5 -8.5. However, many process solutions intentionally exceed this pH range for the purpose of
Nov 01, 2000.Another method of stripping the anodic coating uses various combinations of sulfuric acid and chromic acid at about 130-140F. This chemistry will readily remove the anodic coating but will not remove aluminum in the process, as caustic soda does. This was a popular stripper and desmutter in anodizing lines until about 1970 when environmental

There is a simple explanation for the difference. Aluminum strip costs more to fabricate. Because of the metals inferior corrosion resistance in the radiator environment, it has to be clad with a sacrificial alloy on the water side in addition to the brazing alloy that is clad on the air side.
Chitosan has been used alone or in conjunction with a salt, such as aluminum sulphate, as an aid for the removal of various waterborne contaminants. Modified chitosan relates to grafted anionic or cationic groups onto the C-6 hydroxyl group or the amine group at C-2 on the glucosamine monomer of chitosan.
