Magnesium chloride has a very wide range of uses and can be used as an excellent fire retardant. Its fire resistance is relatively high. Let me explain why magnesium chloride can play a role in fire protection.
1. Magnesium chloride has strong water absorption, and can form a water-wet film. The wet film will isolate the air, and it will naturally play a fire-proof effect.
2. Magnesium chloride fire retardant changes the ionization characteristics of the surface of flammable molecules, making it less prone to oxidation reaction. Without the continuous accumulation of heat, it naturally plays a good role in fire prevention.
3. Once a flame occurs, after reaching a certain temperature, magnesium chloride can quickly decompose and release chlorine gas to achieve rapid fire extinguishing effect.
