Abstract
The invention relates to a cold aerosol extinguishant. The cold aerosol extinguishant which is prepared from the raw materials of 50-80 parts of solid ammonium polyphosphate, 3-10 parts of talcum powder, 8-22 parts of silica, and 5-15 parts of magnesium stearate is concretely prepared by uniformly mixing the raw materials, and carrying out air flow crushing until the average crushing granularity is less than 5mum. The cold aerosol extinguishant prepared in the invention, which has a test fire extinguishing concentration of 50-70g/m<3> in a closed space, has a very good application prospect.
Description
Technical field
The invention belongs to fire prevention fire extinguishing field, particularly a kind of cold aerosol fire extinguishing agent.
Background technology
In existing fire-fighting automatic fire extinguishing system field, hot aerosol fire-fighting technique obtains promotion and application widely, hot aerosol automatic fire extinguishing technology be place in specific container a kind of synthesis containing oxygen solid fuel substance, i.e. hot-gas sol fire extinguishing agent, this material outer spray after ignition combustion during fire extinguishing, in confined space, produce the colloidal sol shape powder of high degree of dispersion, be evenly distributed in space, reach the object rapidly and efficiently suppressing fire.Because nozzle temperature is high, there is many related problems caused by thermal response, such as: (1) in this fire-fighting technique when putting out a fire. flame outer spray during burning, produces the danger of secondary initiation fire; (2). equipment surface temperature is too high; (3). produce toxic gas; (4). when higher temperatures, particulate floating interval of floating dock is longer.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of cold aerosol fire extinguishing agent is provided.
The technical solution used in the present invention is:
A kind of cold aerosol fire extinguishing agent, prepared by following several raw material: solid APP 50-80 part, talcum powder 3-10 part, silica 8-22 part, dolomol 5-15 part, above-mentioned raw materials is mixed, select air-flow crushing, pulverize particle mean size and be less than 5 microns, obtained cold aerosol fire extinguishing agent.
More preferably, the parts by weight of above-mentioned raw materials are: solid APP 60-80 part, talcum powder 3-8 part, silica 1 2-22 part, dolomol 5-12 part.
More preferably, the parts by weight of above-mentioned raw materials are: solid APP 63 parts, talcum powder 7 parts, silica 14 parts, dolomol 12 parts.
Present invention also offers the application of above-mentioned cold aerosol fire extinguishing agent in fire-fighting fire extinguishing.
The application of cold aerosol fire extinguishing agent of the present invention in fire-fighting fire extinguishing, using method is: be placed on by above-mentioned cold aerosol fire extinguishing agent in extinguishing chemical storage tank, extinguishing chemical storage tank is discharged into after gas receives enabled instruction, cold aerosol fire extinguishing agent by gas dispersion and with gas and vapor permeation to release pressure after sprayed by shower nozzle and formed dissolved colloidal state can be floating in atmosphere gas-solid mixture, burning things which may cause a fire disaster is put out a fire.
Preferably, described gas is inert gas or nitrogen or carbon dioxide.
The beneficial effect that the present invention has:
Cold aerosol fire extinguishing agent of the present invention, its usability, compared with hot-gas sol fire extinguishing agent, does not attach secondary harm, ensure that the security of application; Atmospheric environment is had no adverse effects simultaneously, both can not damage the ozone layer, also can not produce greenhouse effects, have corrosion-free, pollution-free, to human non-toxic, harmless feature; Its fire-fighting efficiency is compared with common powder extinguishing agent, and fire-fighting efficiency is high, speed is fast and the low easy-clear of extinguishing concentration; Its initial cost and life-cycle costing are compared with heptafluoro-propane and mist extinguishing chemical, cheap.Visible, its various performance of cold air sol fire-fighting technique all has obvious superiority, will become the current research direction of fire-fighting automatic fire extinguishing technology, test extinguishing concentration 50-70 gram of/cubic metre of confined space of the cold aerosol fire extinguishing agent that the present invention obtains, has good application prospect.
