Embodiment 1
[0050] An aluminum cover oxidation process disclosed by the invention comprises the following steps:
[0051] Preliminary preparation:
[0052] The first auxiliary agent configuration: 3% of sodium molybdate, 10% of water-soluble phosphoric acid ester, 3% of sodium borate and 84% of water are mixed uniformly by weight percentage.
[0053] Modified degreasing liquid configuration: 30 parts by weight of sodium carbonate, 20 parts of trisodium phosphate, 1 part of sodium metasilicate, 1 part of triethanolamine oleate, 10 parts of the first auxiliary agent, and 3 parts of trisodium citrate , 10 parts of adjuvant, 7 parts of ethanol, 10 parts of water softener and 80 parts of water are mixed evenly for later use.
[0054] Configuration of sealing agent: 30 parts by weight of triethanolamine, 1 part of fatty alcohol polyoxyethylene ether, 20 parts of sodium naphthalene sulfonate, 5 parts of sodium acetate, 1 part of chelating agent and 0.5 part of fading inhibitor are mixed uniform...
