  (2)铜及其合金的化学抛光盛京棋牌。铜和单相铜合金可以在硝酸-硝酸-单乙酸或硫酸-硝酸-铬酸的溶液中进行化学抛光。通常,在使用过程中应加入硝酸。如果在抛光过程中二氧化氮沉淀,则部件表面为深黄色。此时,硝酸可以补充1/3的配置量。为防止多余的水进入水箱,应在抛光前将部件干燥。(3)铝和铝合金的化学抛光。为了获得光亮的表面,必须严格控制抛光液中的硝酸含量。硝酸含量过低,抛光速度慢,抛光后表面光泽差;硝酸含量过高,很可能发生鳞片腐蚀。当磷酸浓度低时,不能获得明亮的表面。为了防止溶液被稀释,抛光前部件的表面应该是干燥的。乙酸和硫酸可以抑制点蚀,使抛光表面均匀细致。硫酸铵和尿素可减少氮氧化物的沉淀,有助于提高抛光质量。少量的铜离子可以防止过度腐蚀,从而提高抛光表面的均匀性,但过量的含量会降低抛光表面的反射能力。铬酸酐可以改善铝-锌-铜合金的抛光质量,并且含锌和高强度铝合金的强度难以在不含铬酐的抛光溶液中获得光亮的表面。化学抛光的部件通常在室温下浸入400-500g/L的硝酸或100-200g/L的铬酐溶液中数秒至数十秒,以除去表面接触的铜。
