An explosion-venting method for an aerosol fire suppression apparatus, comprising the following steps: 1) when the aerosol fire suppression apparatus explodes, an explosion-venting apparatus matching the aerosol fire suppression apparatus generating a limited displacement along a direction that a hot air stream of the aerosol fire suppression apparatus is jetting towards; 2) when an extremity of the explosion-venting apparatus reaches an edge of the aerosol fire suppression apparatus, being limited, the explosion-venting apparatus stops the displacement along the direction that the hot air stream of the aerosol fire suppression apparatus is jetting towards, thus achieving for the aerosol fire suppression apparatus the effects of explosion-venting and reduced recoil force. The explosion-venting method, within a limited displacement of the explosion-venting apparatus, completely consumes powerful kinetic energy of a relative motion between a canister body and a canister cover component generated by the explosion, thus allowing smooth ventilation of the powerful explosion, thereby preventing a powerful recoil force generated thereby from injuring an operator, while at the same time preventing the canister cover component from flying outwards at a great speed and causing accidents resulting in injuries and damages.

The present invention relates to a fire-extinguishing composition comprising an organic acid compound, wherein the fire-extinguishing composition comprises an organic acid compound. The content of the organic acid compound is 50% by mass or more, and preferably 70% to 90% by mass. The organic acid compound according to the present invention may absorb heat and be decomposed at a high temperature, and release a fire-extinguishing substance. The fire-extinguishing substance may react, by means of free radicals, with one or more of O·,OH·,H· free radicals that are necessary for chemical-looping combustion, thus cutting off the chemical-looping combustion, or may reduce the oxygen partial pressure by physical action to inhibit the flame, or achieve the fire-extinguishing effect by both the physical and chemical inhibition effects. At the same time, the organic acid compound achieve a synergistic effect together with a firework powder, thereby further improving the fire-extinguishing performance of the fire-extinguishing agent, and greatly shortening the effective fire-extinguishing time.

The present invention relates to a fire-extinguishing composition, wherein the fire-extinguishing composition comprises a main fire-extinguishing component of 60% to 95% by mass and an auxiliary fire-extinguishing component of 5% to 35% by mass. In use, the fire-extinguishing composition absorbs heat generated by combustion of firework powder and produce a fire-extinguishing substance through thermal decomposition, and the fire-extinguishing substance ejects along with a hot aerosol generated by combustion of the firework powder, to achieve the fire-extinguishing effect. The fire-extinguishing composition makes up performance loss of a common cooling layer on an aerosol generating agent, enhances the fire-extinguishing performance of the whole fire-extinguishing product, and at the same time, reduces the temperature of the product at the spout.

A new fire extinguishing composition is provided. The composition comprises ferrocene of 5-39 mass% and a fire retardant component of 61-95 mass%. A firework medicament is used as the heat source and power source of said fire extinguishing composition, and the firework medicament is combusted to generate high temperature to enable the composition to perform heat decomposition reaction so that the resulting fire extinguishing substances can be spouted with the firework medicament to achieve an effect of fire extinguishing. The mixing ratio of the ferrocene is precisely determined and optimized. Fire extinguishing substances can be released by heating the ferrocene to make it decompose and sublimate so that the fire extinguishing efficiency of the ferrocene composition is greatly improved and the fire extinguishing period is shorten.
