How to Prevent Overheating of Magnesium Oxide Reaction in High Summer Temperatures Leading to Board Deformation?

During the summer, temperatures rise significantly, especially when the ground temperature reaches 30°C. In such conditions, the temperature inside the workshop can reach between 35°C and 38°C. For the highly reactive magnesium oxide, this temperature acts as a negative catalyst, significantly accelerating the reaction time between magnesium oxide and other raw materials. It's important to note that magnesium oxide is extremely reactive and releases a substantial amount of heat during chemical reactions. When the reaction occurs too quickly, the entire board releases a large amount of heat, which primarily affects the evaporation of moisture during the curing process.

When there is a sudden increase in temperature, moisture evaporates too quickly, leading to unstable internal structures in the board as the water required for proper reactions evaporates prematurely. This results in irregular deformation of the board, similar to baking cookies at too high a temperature. Additionally, the molds used for forming the boards may be damaged due to excessive heat.

So, how do we prevent this from happening? The answer is retarding agents. We incorporate additives in the formula to slow down the reaction of magnesium oxide under high temperatures. These additives effectively control the reaction time of the raw materials without negatively affecting the original structure of the boards.

Implementing these measures ensures that our magnesium oxide boards maintain their structural integrity and quality even during the high temperatures of summer. By carefully controlling the reaction process, we can prevent deformation and deliver reliable, high-quality products to our customers.
