济南铝板http://www.jngdly.com/在浸蚀前先用机械方法去除表面的毛刺、熔合线及铸造残渣,然后经碱性脱脂剂脱脂干净后进行浸蚀,已钎焊的铝板在浸蚀前应先去焊渣。铝是两性金属,即可溶于酸也能溶于碱。所以浸蚀液既有酸性的也有碱性的,但大多数光亮浸蚀是在酸性浸蚀剂中进行的。

1、济南铝板酸性浸蚀剂常选用硫酸、硝酸、铬酸及磷酸。硝酸的存在易造成大量黄烟生成,污染环境。采用磷酸和硫酸再配以一些含硫的杂环有机物可以取代硝酸,其光泽很好,缺点是对铝板效果较差。
Ji'nan aluminum acid etching agent sulfuric acid, nitric acid, often choose chromic acid and phosphoric acid. Nitrate is easy to cause a large number of tobacco production,pollution of the environment. Using phosphoric acid and sulfuric acid combined with heterocyclic organic compounds containing sulfur can replace some of nitric acid, the luster is very good, the disadvantage is poor effect on aluminum plate.

2、济南铝板http://www.jngdly.com/在碱性浸蚀剂中常用火碱、纯碱和磷酸三钠,另加少量表面活性剂。铝板在一般的碱性脱脂剂中即可进行,温度要在40℃以上。
Ji'nan aluminum in alkaline etchant used in caustic soda, soda ash and sodium phosphate three, plus a small amount of surface active agent. Aluminum can be carried out in alkaline degreasing agent in general to 40 DEG C, the temperature on.

3、选用双氧水和氢氟酸,也可选用双氧水和冰醋酸。例如,选用双氧水45mL/L、冰醋酸80 mL/L在室温下浸10~15s即可。济南铝板浸蚀操作要在通风条件下进行,铝及铝板的品种繁多,要根据不同材质选择不同的浸蚀剂。
Selection of hydrogen peroxide and hydrofluoric acid, can also use hydrogen peroxide and acetic acid. For example, the selection of hydrogen peroxide, 45mL / L acetic acid 80 mL/ L at room temperature and soak for 10 ~ 15s to. Ji'nan aluminum etching operations to be carried out under the conditions of ventilation in the aluminum and the aluminum

plate, a wide variety, according to the different material choose different chemical etchant.
