What issues might magnesium sulfate boards encounter?

Many people still associate magnesium sulfate board with magnesium chloride board. If magnesium sulfate board is produced following the methods used for magnesium chloride board, numerous issues will arise.

Firstly, magnesium sulfate board requires an accurate ratio of magnesium oxide and magnesium sulfate. An inaccurate ratio can lead to alkali efflorescence or frost formation.

Next, magnesium sulfate boards are highly prone to deformation if the magnesium content is too high.

Magnesium sulfate boards can lack strength if the magnesium sulfate content is too high, causing them to dry too quickly.

Magnesium sulfate boards are also quite demanding in terms of maintenance conditions. These boards must undergo secondary maintenance or be naturally dried before shipment. Moist boards only have about 60% of the strength of dry boards.

Magnesium sulfate boards are not as simple as making them with a recipe; there are many issues that require attention and improvement.
