⑵ proportion: ＞1.0

⑶ PH value : ＜7.0

4. Usage method:

This product is mixed with water two times, blackening time is 3-5 minutes, blackening temperature is 80℃±5℃.

Operation flow: 

⑴ Magnesium alloy is removed oil, grinded, polished, you can clean and bright magnesium alloy surface.

⑵ Black deactivation of magnesium alloy agent is added 2 times of the water, and is heated to 80℃±5℃. Mg alloy is immersed in blackening agent for 3-5 minutes.

⑶ washing and drying at 80℃.

5. Matters needing attention:

⑴This product is corrosive, do not contact with the skin.

⑵You should replenish the blackening agent solution to restore the effect, due to the consumption of ingredient during operation.The amount of supplement is 2% - 3%.

⑶Waste water before discharging  go through the biological degradation in sewage tank and filtration treatment.
