アルミホイルを金色にするにはどうすればよいですか?
1) 表面前処理: 化学的または物理的方法でプロファイル表面を洗浄します, 純粋なマトリックスを公開する, 完全で緻密な人工酸化膜を得るために. 鏡面またはマット (マットな) 表面は機械的に取得することもできます.
2) 陽極酸化: 表面前処理プロファイルの場合, under certain technological conditions, the substrate surface will be anodized to form a dense, porous and strongly adsorbed Al203 film.
3) Hole sealing: seal the pores of the porous oxide film formed after anodic oxidation to enhance the anti-pollution and anti-corrosion wear resistance of the oxide film.
酸化皮膜は無色透明です. Using the strong adsorption of the oxide film before sealing the hole, some metal salts are adsorbed and deposited in the film hole, giving the appearance of the outline a variety of colors in addition to the natural color (silvery white), such as black, ブロンズ, gold and stainless steel.
