Magnesium sulfate monohydrate is currently used in a wide range of industries. When used as a flame retardant, it can also exert its proper performance. Because of its own heat insulation and heat absorption functions, it can play a flame retardant effect. The following is to explain the reasons for flame retardants.
1. Magnesium sulfate monohydrate decomposes when heated (340-490 ° C), absorbs the heat of the surface of the burner to the flame retardant effect, and releases a large amount of water to dilute the oxygen on the surface of the burner, and the active magnesium oxide formed by the decomposition adheres to the surface of the combustible It further prevented the combustion from proceeding.
2. During the entire flame retardant process, magnesium sulfate monohydrate not only produced no harmful substances, but also its decomposition products could absorb a large amount of harmful gases and smoke generated by the combustion of polymers such as rubber and plastic while being flame retardant. Magnesium oxide continuously absorbs the incompletely combusted melting residues, which eliminates smoke and stops molten droplets while stopping combustion quickly. It is an emerging environmentally friendly inorganic flame retardant.
