▎ 摘 要
NOVELTY - Normal temperature 6061 aluminum bright acid washing liquid comprises primary acid washing liquid and secondary acid washing liquid. The primary acid washing liquid comprises 0.5-1 wt.% nitric acid, 1-2 wt.% citric acid, 0.3-0.5 wt.% phytic acid, 0.1-0.3 wt.% brightening agent, 0.1-0.5 wt.% chelating agent and water (balance amount). The secondary acid washing liquid comprises 1.5-3 wt.% nitric acid, 1-2 wt.% citric acid, 0.3-0.5 wt.% sulfamic acid, 0.3-0.5 wt.% ammonium molybdate, 0.2-0.5 wt.% brightening agent, 0.1-0.2 wt.% corrosion inhibitor, 0.005-0.1 wt.% quaternary ammonium salt modified graphene oxide and water (balance amount). USE - The washing liquid is useful in decoration, packaging, building, transportation, electronic, aviation, spaceflight and weapon industries. ADVANTAGE - The washing liquid has excellent corrosion resistance, and can keep the appearance effect with uniform color. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for acid cleaning method of 6061 aluminum alloy.
