| titleOfInvention | A chemical polishing additive and polishing process for aluminum alloy two-acid chemical polishing |
| abstract | The invention relates to a chemical polishing additive for aluminum alloy two-acid chemical polishing. A chemical polishing additive for two-acid chemical polishing of aluminum alloy, said additive is composed of 70-80 parts by weight of 85% concentrated phosphoric acid, 10-12 parts by weight of mercaptophenyl tetrazolium, and 7-10 parts by weight of brightener , 3-5 parts by weight of the surfactant composition, the additive is used to add aluminum ion concentration of 15-35g/L two-acid chemical polishing bath, the amount of the additive is 8-12% of the volume of the bath. The invention also relates to polishing processes. The chemical polishing additive of the present invention is used when the concentration of aluminum ions in the bath solution is 15-35g/L, which can ensure the polishing effect of 5252 aluminum alloy, and can greatly reduce air marks and flow marks. |
