Abstract

The invention discloses a magnesium alloy pickling activator for pickling activation treatment of magnesium alloys, which takes water as a solvent and comprises citric acid at a concentration of 5 to 10g / L, lactic acid at a concentration of 10 to 20g / L and inorganic strong acid at a concentration of 2 to 4g / L. The invention also provides a magnesium alloy pickling method. In the magnesium alloy pickling activator and the magnesium alloy pickling method, a mixture of organic acids and an inorganic acid is used, chromium compounds are eliminated, environment pollution is avoided, the reaction in the solution is mild, the cleaning capacity is high, the oxide, release agent and silicon impurities on the surface of the magnesium alloy can be better removed, and the surface of the magnesium alloy has the texture of silvery white metal.

Description

【Technical field】

[0001] The invention relates to a pickling activator and a pickling method, in particular to a magnesium alloy pickling activator and a pickling method for pickling activation treatment of magnesium alloys. 【Background technique】

[0002] Magnesium alloy is lighter than engineering plastics, and with the gradual reduction in weight and thickness of consumer electronic products, it has gradually become the main basic material in consumer electronic products such as notebook computers, mobile phones, PDAs and projectors, and has become a material for electronic information products. As a rising star, the scope of application of magnesium alloys has rapidly expanded. In industrial production, the surface treatment of magnesium alloys is becoming more and more important. The surface treatment is mainly to improve the appearance of the product and improve the wear resistance and corrosion resistance.

[0003] Before the magnesium alloy chemical conversion treat...
