Description
Technical Field
The invention relates to the technical field of forest fire fighting, in particular to a composite forest dry powder extinguishing agent based on ammonium oligomeric phosphate and a preparation method and application thereof.
Background
Forest fires are a frequently occurring natural disaster phenomenon and are strong in burst property and large in destructiveness. The occurrence of forest fire not only causes great loss to national forest resources and lives and properties of people, but also causes serious damage to the ecological environment, and the recovery period after the fire is over takes ten years or even hundreds of years. In order to control and suppress forest fires, fire suppression technologies are constantly being developed and improved in various countries around the world.
In actual fire extinguishing, large water drops are sprayed on combustible substances which are being combusted, so that the method is an effective way for extinguishing forest fires and is a forest fire-fighting strategy commonly used in forest areas. When a forest fire is extinguished, the optimal fire extinguishing effect can be achieved only by extinguishing the flame of combustible materials in a unit area with 1-2.5 times of water.
In many hills, mountains and plateaus with complex terrains and fluctuating terrains, once a forest fire occurs, forest firefighters are difficult to reach a fire scene in time and sometimes even can not reach the fire scene. The aerial fire-extinguishing airplane has the aerial advantages of high speed, no terrain limitation and the like, and can directly fly to a fire scene to carry out water-carrying fire extinguishing. The fire extinguishing by water has good effect on coping with ditch and pond fire, bush fire, grassland fire and tree crown fire, but has unsatisfactory fire extinguishing effect due to the blockage of the tree crown when coping with forest surface fire. At present, chemical fire extinguishing agents for forests generally comprise main agents, auxiliary agents, thickening agents, wetting agents, preservatives, coloring agents and other components, contain a large amount of water, are mainly used for physical fire extinguishing, and have limited fire extinguishing effect.
The fire extinguishing agents commonly used at present can be divided into two categories according to the fire extinguishing mechanism: chemical fire extinguishing and physical fire extinguishing. Chemical fire extinguishing adopts the chemical inhibition effect when chemical substances meet with flames to capture combustion free radicals, block combustion chain reaction and extinguish the flames, so that the fire extinguishing speed is high and the fire extinguishing efficiency is high. Physical fire extinguishing adopts suffocation fire extinguishing, so that fire cannot be extinguished due to combustion oxygen, and therefore, the fire extinguishing speed is low and the efficiency is low. But the physical fire extinguishing mode has unique effect on extinguishing flameless combustion (smoldering) of combustible solid and preventing re-combustion of combustible liquid.
The first dry powder extinguishing agent based on sodium bicarbonate was developed in the United states, and various products have been developed to date. Class ABC: an ammonium phosphate salt; class BC: sodium bicarbonate, potassium bicarbonate, and the like; and D type: graphite fire extinguishing agents, and the like. The dry powder extinguishing agent has excellent extinguishing rate and efficiency. The dry powder extinguishing speed is 2.5 times that of alkyl halide, 4 times that of carbon dioxide, 20 times that of foam and 40 times that of water.
The substances which can play a role in extinguishing fire in the existing domestic products mainly comprise: ammonium phosphate salts, ammonium carbonate salts, sodium chloride, potassium chloride, and the like. The content of fire extinguishing components of the common dry powder fire extinguishing agent is strictly regulated in national standard, the content of ammonium dihydrogen phosphate is more than or equal to 75 percent, and the content of sodium bicarbonate is more than or equal to 82 percent.
The superfine dry powder extinguishing agent consists of active extinguishing component, crushing assistant component, hydrophobic component, inert stuffing component, etc. The fire extinguishing component is the core of the superfine dry powder fire extinguishing agent. The superfine dry powder extinguishing agent organically combines the advantages of chemical extinguishing and physical extinguishing, and has the functions of chemical inhibition of flame combustion, suffocation of flameless combustion, shielding and cooling of heat radiationThe centralized embodiment of the fire extinguishing agent characteristic. The content of fire extinguishing components is not regulated by related industry standards, but the fire extinguishing efficiency index is strictly regulated to be less than or equal to 150g/m 3 。
