Non-combustible is the substance itself cannot burn, flame retardant is not burning ability or not easy to burn.
The difference between flame retardant and non-flammable
1, non-combustible is the substance itself can not burn, flame retardant is not burning ability or not easy to burn.
2, flame retardant can sometimes be close to or contact with fire, such as asbestos flame retardant, gasoline fire prevention. Flame retardant can also be understood as fire resistance, which is different from non-flammability, which means that the substance is not inflammable, rather than not inflammable.
3, all flame retardant materials
Not all of them are flammable, flammable materials. Flame retardants are mainly organic and inorganic, halogen and non-halogen. Organic is bromine series, nitrogen series and red phosphorus and compounds as the representative of some flame retardants, inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flame retardant system.
Endothermic action
The heat released in the combustion process heats the raw material, so that it quickly reaches the ignition point. The principle of endothermic flame retardant is that the material needs to absorb a lot of heat in the combustion process, so that the material can reduce the heating process, so that the combustible molecules of gasification pyrolysis free radicals
It is difficult to reach the ignition point, which inhibits the combustion to some extent.
The high temperature generated by the combustion of the material makes the flame retardant form a glassy or stable foam covering layer, which cuts off oxygen. In this way, it is not only heat insulation and oxygen insulation, but also prevents the escape of the gas outside the body, so as to achieve the purpose of flame retardant.
Inhibitory chain reaction
Action According to the chain reaction theory of combustion, free radicals are needed to sustain combustion. Flame retardants can act on the gas phase combustion zone to capture the free radicals in the combustion reaction, thus preventing the spread of the flame, reducing the flame density in the combustion zone, and finally reducing the combustion reaction speed until the termination.
Non-flammable gas asphyxiation flame retardant when heated decomposing non-flammable gas, the concentration of combustible gas decomposed from combustible material diluted to below the lower limit of combustion. At the same time, the oxygen concentration in the combustion zone has the effect of dilution, prevent the continuation of combustion, to achieve the role of flame retardant.
