Now there are a lot of flame retardant fabric on the market, if you do not understand the product is likely to choose the wrong, then how to choose it? The following points must be taken into consideration when choosing a flame retardant fabric:
The phase of the combustion process and the phase state of the flame retardant effect (gas phase or condensed phase). Clear the combustion process stage (decomposition, lead to or combustion), and flame retardant fabric phase in the corresponding stage of combustion, that is to play gas phase flame retardant mechanism, or condensed phase flame retardant mechanism, or is a synthesis of several mechanisms.
Flame retardant fabrics must be at the right time and the right place to play a role, that is, the decomposition temperature of the flame retardant and the decomposition temperature of the flame retardant cloth. The best flame retardant effect was achieved by using mixed flame retardant fabric. A flame retardant cloth is slightly lower than the decomposition temperature of the flame retardant substrate to play a flame retardant effect, while the other is in the decomposition of the substrate weight loss 5O% and achieve maximum decomposition rate when the flame retardant effect.
Less use or not to be affected by the flame retardant materials. There are many ways to classify the flame retardant fabrics. According to the method of flame retardant fabric and material application can be divided into: adding flame retardant fabric type and reaction type flame retardant fabric, backbone modified flame retardant fabric, flame retardant fabric essence, nano doped flame retardant fabric; according to the element composition and classification: halogen flame retardant fabric, phosphorous flame retardant fabric, nitrogen system flame retardant fabric, silicon flame retardant fabric, boron flame-retardant cloth, inorganic hydroxide, inorganic metal compounds, inorganic non metal compounds, organic and inorganic complex flame retardant cloth and so on. According to the synergistic effects of classification: phosphorus nitrogen synergism, phosphorus halide synergies, phosphorus aluminum synergistic effect and composite flame retardant system (intumescent flame retardant fabric).
