The invention has wide application for extinguishing A, B, C fire hazards, with better effect on electric fire, etc. And its extinguishment time is lower than 2s and effect is lower than 60g/m3, on the A, B, and C fire hazards.
Description
Technical field
The present invention relates to the powder extinguishing agent composition, relate in particular to a kind of whole submerged dry chemical extinguishing agent.
Background technology
Halogenated hydrocarbon series extinguishing chemical, being commonly called as Kazakhstan dragon (Halon) extinguishing chemical once was widely used, but it is serious to depletion of the ozone layer, is eliminated by UNEP's regulation time limit, and Chinese Government stipulates to rise on December 31st, 2005 and forbids producing, use and selling the imperial serial extinguishing chemical in Kazakhstan.
Extinguishing chemical commonly used at present has carbon dioxide extinguishing agent, mist extinguishing chemical, aerosol extinguishing agent and ABC powder extinguishing agent etc.Carbon dioxide extinguishing agent reduces the purpose that ambient oxygen concentration reaches fire extinguishing with the carbon dioxide or the interim carbon dioxide that generates of storage, its storage pressure height, and fire-fighting efficiency is low, fire extinguishing in the practicality among a small circle.The mist extinguishing chemical is made up of nitrogen, argon gas and carbon dioxide, and its storage pressure is up to 15MPa, and fire-fighting efficiency is low.Aerosol extinguishing agent, main by the oxidant that contains potassium, potassium nitrate and reducing agent such as resin etc. by the interim inert gas that generates, reduce place on fire oxygen concentration and reach the fire extinguishing purpose, but its security is undesirable.ABC powder extinguishing agent, though can put out A, B, C three class fire, its particle diameter generally surpasses 40 μ m, and powder is bulk inadequately, can not put out a fire in the total flooding mode, fire-fighting efficiency is low.
Publication number is the Chinese patent application of CN1356150A, a kind of superfine powder high-efficiency fire-extinguishant and compound method thereof are disclosed, it mainly is made up of phosphorus ammonium salt fire retardant chemical, silica dispersions and stearate anti-blushing agent, but its powder is bulk inadequately, and its fire-fighting efficiency is not ideal enough.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of powder particle mean size little, powder is bulk, moisture resistance and good fluidity, the powder extinguishing agent that can put out a fire in the total flooding mode.
The technical scheme that realizes above purpose is:
A kind of whole submerged dry chemical extinguishing agent is characterized in that:
