Magnesium Hydroxide uses for Construction
Construction Application (Fire Proof)
As a new type of fire extinguishing material, magnesium hydroxide has higher fire extinguishing performance than the traditional dry powder, and its scope of application is more extensive. The main reason why Superfine magnesium hydroxide powder has high fire extinguishing performance is that it has the function of chemical inhibition and physical cooling.

Ammonia and Brine
Superfine magnesium hydroxide powder has large specific surface area, high activity and strong ability to trap free radicals, it would decompose fast when heated.
1. Decomposition of magnesium hydroxide absorbs potential heat, which is beneficial to reduce the flame combustion temperature.
2. The magnesium hydroxide create water when decomposition, it’s not only the coolant, but also reduce the smoke density obviously.
3. The decomposition of magnesium hydroxide creates MgO, also called the carbon layer, which can easily absorb smoke and cover the combustible material.
