What is problem with MgO Boards made of Magnesium Chloride?
Magnesium chloride oxide board has weakness of halogenide. When it occurs, you can see water droplets lying on the surface of the board. It looks like the board is “sweating”. The “sweats” will corrupt board, which may crack and even fall apart over time. The main reason causing halogenide is excess free available chlorine in the board. Factories and research institutes have made a lot of efforts to ensure the removal of excess free available chlorine.
