Description
Technical field
The invention belongs to the fire-fighting fire extinguishing technical field, relate to a kind of novel hot aerosol extinguishing agent and preparation method thereof.
Background technology
At present, aerosol fire-extinguishing device mainly is to have extinguishing chemical to pass through electronic starter, pass through burning with the pyrotechnic composition form, produce a large amount of inert gases and nano level solid particle, when these materials are discharged in the guard plot, to airborne oxygen consumption and its concentration of dilution, thereby make comburant surface anoxic and realize putting out a fire.
According to the regulation of industry, the aerosol extinguishing agent type that exists on the market has three kinds now, i.e. K type, S type and its alloytype.They are formed by Oxidizing and Reducing Agents, and oxidant divides single-oxidizer and composite oxidant.So-called composite oxidant generally is strontium nitrate (Sr (NO
3)
2), its content is generally at 35%-50%(percentage by weight, down together) and potassium nitrate (KNO
3), its content is generally 10%-70%, or only contains strontium nitrate (Sr (NO
3)
2), its content is 50%-70%; Reducing agent is made up of some combustibles.In the oxidant constituents of these extinguishing chemicals, all contain potassium nitrate (KNO
3), and potassium nitrate (KNO
3) chemical equation is as follows:
So in the combustion product of these panoramic extinguishing chemicals, must contain potassium oxide (K
2O), potash (K
2CO
3), saleratus (KHCO
3) waiting material, these materials run into the material that the water in air steam will form strong corrosion.Thereby to material to be protected, particularly electric equipment can play the secondary destruction; Secondly in reducing agent, gaseous state ammoniacal liquor (NH is arranged also
3.H
2O), gaseous state carbonic acid (H
2CO
3), great amount of carbon dioxide gas (CO
2) wait existence, also can produce corrosiveness to protected object.
In addition, the technical process of these aerosol extinguishing agents is also loaded down with trivial details, and requires the composition material granularity to reach more than 100 orders, has therefore caused the factory building dust big, and the employee is caused great dust injury etc.
