How does the flame retardant short fiber flame retardant?

(1) Sucking effect. A flame retardant having a high heat capacity, a heat insulating reaction such as phase change, dehydration or dehydrogenation, reduces the temperature of the surface of the fibrous material, and slows the temperature of the thermal cracking reaction, and suppresses the rate of the thermal cracking reaction in high temperature.

(2) Cover the protection effect. After the flame retardant is heated, the glass-shaped cover layer is melted in the surface of the flame retardant short fiber material, which is a barrier between the coagulation phase and the flame. Both oxygen, block the diffusion of the flammable gas, but also block heat conduction and heat radiation, reduce heat feedback to the fiber material, thereby suppressing thermal cracking and combustion reactions.

(3) Gas dilution effect. The flame retardant heat-absorbing decomposition releases nitrogen, carbon dioxide, sulfur dioxide and ammonia and other non-fuel gases such that the flammable gas concentration of the fibrous material cleavage is diluted to the combustion limit. Or insufficient oxygen in part in the center of the flame center, prevent combustion continues. In addition, this intra-fuel gas also has heat dissipation. Their flame retardant effect is: N2> CO2> SO2> NH3.

(4) Combined phase flame retardant. Through the action of the flame retardant, the thermal cracking reaction process of the fiber generic chain is changed in the coagulation phase reaction zone, which causes dehydration, condensation, cyclization, cross-linking, etc. until carbonization, to increase carbonized residue, reduce flammable gas. Produce, the flame retardant exerts a flame retardant effect in the agglomeration phase. The effect of aggluting flame retardant effects is closely related to the matching of the flame retardant in the chemical structure.

(5) gas phase flame retardation. A small amount of inhibitor is added, capturing a large number of lightweight free radicals and hydrogen radicals in the flame region, reducing the radical concentration, thereby inhibiting or interrupting the combustion chain reaction, and exerts a flame retardant effect in the gas phase. The chemical structure of a gas-phase flame retardant to fibrous material is not sensitive.

(6) Surface effect of fine particles. If there is a certain amount of inert fine particles in the combustible gas, it can not only absorb the combustion heat, reduce the flame temperature, and, as the wall surface of the container, a large amount of high energy hydrogen radicals in the gas phase combustion reaction is applied to the surface of the particles. It is converted to a low energy hydrogen peroxy-free radical, thereby inhibiting gas phase combustion.

(7) Sollow drop effect: some thermoplastic synthetic fibers, such as polyamides, polyesters, shrinkage droplets in heating, decreased with air contact area, even droplets falling to leave the fire source, so that combustion is subject to certain Hinder.
