20140183400 | FIRE EXTINGUISHING COMPOSITION OF COPPER SALTS - Disclosed is a fire extinguishing composition of copper salts, which comprises a compound of copper salts and a fire retardant component with the content of 30 wt %--95 wt % for the former and 5 wt %-70 wt % for the latter respectively. A pyrotechnic agent in the composition serves as heat source and power source, and through being ignited, the pyrotechnic agent is burnt to generate high temperature to enable the composition to perform decomposition reaction so that a large quantity of the resulting fire extinguishing substances can be spouted out with the pyrotechnic agent to achieve an object of fire extinguishing. The fire extinguishing composition of copper salts can decrease the quantity of heat released by combustion of the pyrotechnic agent rapidly and efficiently, thus greatly reducing the nozzle temperature of a fire extinguishing apparatus and a sprayed substance, avoiding use of a complicated cooling system of the fire extinguishing apparatus, and also eliminating the danger of a secondary fire. the fire extinguishing composition releases a great deal of an effective fire extinguishing substance at the moment of being heated, through the synergistic effect of various particles, the fire extinguishing time is greatly shortened. | 07-03-2014 |
