Flame retardant principle and combustion fake principle

Flame retardant principle:

To clarify the principle of fabric flame retardation, first understand the combustion process of the fabric. The combustion process of the fabric is an extremely complex thermal oxidation reaction, resulting in the basic elements of the combustion of heat, oxygen and flammable gas. It is generally believed that the combustion of fabrics has experienced the following three stages. Thermal initiation process, thermal degradation process and ignition process. The principle of flame retardant flame retardation is to add a certain amount of flame retardant in the fabric, which can increase the oxygen index, and the flame retardant effect is obvious.

Principle:

In the combustion simulation environment laboratory, 6 groups of 12 firefighters were installed around the combustion fake people, each firewer 84 (kW / m2) heat flow can be supplied within 2 seconds to 3 seconds, and the firefighter is simulated in the real fire. At the end of the experiment, by analyzing the number of the dummy output to each sensor , the heat flow can be accurately reported to report the burn level of the skin on the skin of each sensor, the total area of burns, constitute two and three Level burn time.
