Effect of acid washing treatment on magnesium ingots

Remove impurities attached to the surface of magnesium ingots and add processes to prevent film oxidation. Magnesium is one of the metals with poor corrosion resistance, and magnesium ingots are exposed to corrosion in the atmosphere. In addition, some impurities attached to the surface of magnesium ingots, such as inorganic chloride salts and electrolytes, can also have a strong corrosive effect on magnesium. Therefore, the refined magnesium ingot must undergo appropriate surface protection to reduce the corrosion loss of magnesium. Magnesium ingots during storage. The surface treatment method of magnesium ingots varies depending on the length of storage time and user requirements.

Appearance requirements for magnesium ingots: smooth surface, glossy finish, no black oxidation spots, and no obvious shrinkage pores
