[0014] Example 1
[0015] A low-polluting aluminum alloy polishing process. The polishing liquid is made of the following components in parts by weight: 15 parts of phosphoric acid, 14 parts of sulfuric acid, 12 parts of nitric acid, 11 parts of citric acid, 9 parts of sodium polyphosphate, 8-hydroxyl 5.5 parts of quinoline, 4.2 parts of thiourea, 20 parts of polyethylene glycol, 25 parts of hydrogen peroxide, 10 parts of copper sulfate, 2.5 parts of sodium hexametaphosphate, 1.5 parts of urea, 1.0 part of nickel sulfate, 0.5 part of sodium hydroxide, polishing treatment The process includes the following steps:
[0016] (1) After washing and drying the chemically degreasing aluminum alloy, immerse it in the polishing solution. After polishing for 60 seconds, take it out. Immediately wash the polished aluminum alloy with water to completely wash off the remaining polishing solution on the surface. Rinse with deionized water 3 times;
[0017] (2) Then place the aluminum alloy in a s...

[0028] Example 3
[0029] A low-polluting aluminum alloy polishing process. The polishing liquid is made of the following components in parts by weight: 18 parts of phosphoric acid, 16 parts of sulfuric acid, 14 parts of nitric acid, 13 parts of citric acid, 10 parts of sodium polyphosphate, 8-hydroxyl Quinoline 5.8 parts, thiourea 4.5 parts, polyethylene glycol 25 parts, hydrogen peroxide 30 parts, copper sulfate 12 parts, sodium hexametaphosphate 2.8 parts, urea 1.8 parts, nickel sulfate 1.2 parts, sodium hydroxide 0.8 parts, polishing treatment The process includes the following steps:
[0030] (1) After washing and drying the chemically degreasing aluminum alloy, immerse it in the polishing solution. After polishing for 90 seconds, take it out. Immediately wash the polished aluminum alloy with water to completely wash off the remaining polishing solution on the surface before using it. Rinse with deionized water 5 times;
[0031] (2) Then place the aluminum alloy in a solution ...
