What are the requirements for the storage of magnesium hydroxide?

What are the requirements for the storage of magnesium hydroxide?

Magnesium hydroxide alias caustic magnesite, light burned magnesia, etc., is a white powder material, is also a new type of filling type flame retardant. By releasing bound water during thermal decomposition and absorbing a large amount of latent heat, the surface temperature of the synthetic material filled with it in the flame is reduced, which has the effect of inhibiting the decomposition of the polymer and cooling the combustible gas generated. However, magnesium hydroxide has certain requirements during storage. The following is a brief introduction to how magnesium hydroxide should be stored. 1. The environment is relatively basic. It is necessary to adhere to the monotony and ventilation of the storage environment, together with the need to lay a layer of plastic film between the product and the ground.
