Description
Technical field
The present invention relates to a kind of high-effect fire-extinguishing material that is used for great burning things which may cause a fire disaster, be specially adapted to the fire extinguishing of large-sized fires such as oil product, ignition control compound, building, colliery, forest and other burning things which may cause a fire disaster control etc.
Background technology
Existing extinguish material mainly contains following several:
(1) water.Water is non-flammable fluid, and it is most widely used in fire extinguishing, is the most cheap extinguishing chemical.The effect one of water fire extinguishing is cooling: 1 ℃ of heat that absorbs 1 kilocalorie of temperature rising of per kilogram water; And the vaporization of per kilogram steam the time will absorb 539.9 kilocalories heat; The 2nd, water has diluting effect to oxygen: water runs into that vaporization produces a large amount of steam behind the red-hot comburant, can stop air to enter the combustion zone, and simultaneously, the content of oxygen in the dilute combustion district, the oxygen that makes the combustion zone reduce gradually and weakens combustion intensity.The 3rd, the percussion of water: after fire pump pressurization, be input to water flow pressure that hydraulic giant ejects and can reach tens or the pressure of meter water columns up to a hundred, have very big kinetic energy impulsive force; The 4th, water is to the diluting effect of water-soluble flammable flammable liquid.The deficiency of its existence is that loss speed is fast, and service efficiency is low, and poor adhesive force infiltrates into undergroundly easily, and the less inflammable thing of proportions such as oil product are not had the fire extinguishing effect, causes easily because of using the excessive pollution in wide area that causes.
(2) paste materials such as clay slurry, yellow mud, coal ash pulp.Go out principle and advantage and water of these materials is near, exists because of the solid composition is arranged, and adhesive force is good slightly, but possesses the shortcoming of water simultaneously.
(3) fire foam.Foam fire-fighting is by the effect by chemistry, physics of the aqueous solution of fire foam, fills the countless minute bubbles of formation behind a large amount of gas.The specific gravity range 0.001～0.5 of bubble much smaller than the proportion of flammable flammable liquid, can cover liquid surface, forms foam blanket.The mechanism of action of foam fire-fighting has: (1) foam has formed foam blanket on the comburant surface, can make comburant surface and air isolated.(2) froth bed has sealed the comburant surface, can interdict the heat radiation of flame, stops the evaporation of comburant itself and near combustible.(3) the clear liquid that goes out of foam cools off burning surface.(4) foam is subjected to the steam of thermal evaporation generation can reduce near the concentration of the oxygen of comburant.The deficiency of its existence is: product cost is higher, and use cost is also high; Closely connect only and separate burning things which may cause a fire disaster, bigger to user's security threat; Dosage is generally less, is not suitable for large-sized fire.
(4) powder extinguishing agent.(1) dry-chemical fire extinguishing principle powder extinguishing agent is stored in dry powder extinguisher or the dry-chemical fire extinguishing equipment at ordinary times.Depend on gas-pressurized (CO during fire extinguishing
2Or N
2) pressure dry powder is penetrated from nozzle, form one vaporific powder that clips gas-pressurized stream, the directive comburant.Dry powder contacts a series of physical-chemical reaction principles of generation with flame as follows:
Sodium acid carbonate is decomposed by high temperature action in the dry powder, and its chemical equation is: 2NaHCO
3=Na
2CO
3+ H
2O+CO
2This reaction is the endothermic reaction, and a large amount of carbon dioxide and water are emitted in reaction, and water is heated and becomes steam and absorb a large amount of heats, plays the effect of cooling, dilution fuel gas; After dry powder enters flame,, reduce evaporation of liquid speed because the absorption and the scattering process of dry powder reduce the heat radiation of flame to fuel.(2) scope of application powder extinguishing agent mostly is contained in the fire extinguisher, is mainly used in the fire of the various water-insoluble and water-soluble flammable flammable liquids of putting out a fire to save life and property, and the fire of the fire of fuel gas such as natural gas and liquefied petroleum gas or general charging equipment.The phosphate powder extinguishing chemical can also put out solid fire.The non-water-soluble liquid fire can be effectively put out in phosphate powder and fluoroprotein foam or aqueous film forming foam coupling.The agent of going out of pluses and minuses and foam is similar, though dosage is big slightly, the burning things which may cause a fire disaster object is polluted bigger, the residual quantity height.
(5) solid incombustible such as glass cloth, asbestos quilt, ceramic fiber cloth, river sand, clay, cement.Mainly, intercept air, thereby play the effect of fire extinguishing by burning things which may cause a fire disaster is covered.Advantage: wide material sources, be easy to keeping, easy operating, use cost is low, and some is reusable, and shortcoming is only suitable small size fire, and continuity is carried in a large number, also closely operation only is bigger to fire fighter's life security threat, can't play effect when fire location is higher.
(6) inert gas agent such as carbon dioxide.CO
2Itself do not burn, not combustion-supporting, easily manufactured, be easy to liquefaction, be convenient to tinning and storage, be a kind of good extinguishing chemical.CO
2Be the gas that a kind of colourless nothing is smelt, it is 1.5 to the proportion of air, and common form is a gas, and the way with the cooling pressurization makes its liquefaction usually, is loaded in the steel cylinder; Solid-state CO
2Being called dry ice, is a kind of good refrigerant.Fire-fighting principle: CO
2Extinguishing chemical is to pressurize with the form of liquid state to fill in fire extinguisher, because CO
2The equilibrium vapor pressure height, cylinder valve one is opened, liquid is immediately by siphon pipe, conduit and nozzle and through the ejection of spray tube, liquid CO
2Vaporization rapidly, and from surrounding air, absorb a large amount of heat, (the liquid CO of per kilogram
2Need 138 kilocalories of heats during vaporization.) but because the spray tube has completely cut off heat conduction to external world, so CO
2During liquid the vaporization, can only absorb the heat of self.Cause the moisture of liquid own sharply to reduce, when its temperature drops to 78.5 ℃ (sublimation point), tiny flakes CO is just arranged
2Solid occurs.So that eject from extinguishing chemical is the CO of very low gas of temperature and solid
2Although, CO
2Temperature is very low, and comburant is had certain cooling effect, yet this effect far is not enough to stamp out the flames.Its fire extinguishing effect mainly be increase in the air do not burn, not combustion-supporting composition, airborne oxygen content is reduced, experiment shows: concentration of oxygen in the air of combustion zone≤12%, CO
2Concentration at 30%～35% o'clock, most burnings all can be extinguished.Though almost be applicable to any burning things which may cause a fire disaster, safety and environmental protection, the deficiency of its existence is: production and use cost are higher, keeping requires high, when running into large-sized fire, is difficult to allocate large number quipments, working condition is comparatively complicated, can't in time produce in a large number. and the user of service has relatively high expectations.
(7) other novel organic extinguish material, as: 1211 (difluorochlobromo-methanes).This class extinguishing chemical interrupts burning mainly by suppressing the chemical reaction process of burning, reaches the purpose of fire extinguishing.Its effect is to finish by the activity material in the combustion chain reaction of taking away, and this process is called chain breaking process and process of inhibition, and is similar to the powder extinguishing agent effect.And other extinguishing chemical mostly is physical processes such as cooling and dilution.Because compound itself contains the composition of fluorine etc., thereby has heat endurance and chemical inertness preferably, never degenerate convenient the use.Also be with nitrogen, CO when using as extinguishing chemical
2Or fluorine Lyons--12 are pressed into container, owing to the pressure effect, with vaporific ejection, become extinction using vapour from nozzle rapidly under the effect of the combustion heat during use.Advantage is applied widely, low-residual; Deficiency is that production, use cost are higher, may produce toxic gas under the condition of high temperature, and social storage level is little, and production, storage facilities are had relatively high expectations, and the large tracts of land fire can't be promoted the use of, and also only is applicable to simultaneously closely to use.
Summary of the invention
The object of the present invention is to provide a kind of cheaply, the viscosity height runs off, seepage velocity is slow, and proportion is controlled, and speed of production is fast, and is easy to use, and performance safety can realize the remote extinguish material of carrying.

The said inorganic silicic acid salt material of component A of the present invention is the framework material of this material of preparation, itself has fire-retardant or anti-fire action.As: alumina silicate fibre.
Component B said (1) blowing agent: the proportion of lightening material, improve utilization efficiency of material, in the face of burning things which may cause a fire disaster such as oil products the time, material can be floated on pasta, carry out fire-retardant, as cement blowing agent.(2) surfactant: with inorganic material from block, powdery or fibrously become glue or pulpous state after adding water, dispersion of materials or connection can be changed material tension, increase the viscosity and the adhesive force of material, strengthen the intermiscibility of inorganic material and water, as: butanedioic acid di-sec-octyl sodium sulfonate.(3) dispersant: inorganic material is dispersed into less state, promotes the effect of surfactant, also can disperse tackified finish to inorganic material separately, as: Sodium Polyacrylate.
The said water of component C: be the shank of this material, utilize water the characteristic of fire to be played the effect of cooling, fire-retardant, diluent air.
Component D is auxiliary material: (1), colloidal materials mainly are the absorption affinities that increases material, be convenient to material and be adsorbed on inflammable surface and play the covering effect, as: white glue with vinyl.(2), the pyrolytic material mainly is to produce decomposition reaction under the condition of high temperature, the gas that is generated can produce diluting effect to air, as carbonic hydroammonium.(3), water absorbing agent, increase suction, thickening, the moisture-retaining capacity of material, improve the viscosity and the water content of material, as polyacrylamide.(4), fire proofing material is the main anti-fire action that rises, improve the product resistance to elevated temperatures, as ammonium polyphosphate.(5), inserts mainly rises increases material proportion, improve transporting velocity and less important absorption and iris action, as clay.(6), mainly to act on be control material proportion such as methyl-silicone oil emulsion to defoamer.
Fire-fighting principle of the present invention is: 1, control ignition point: water content reaches as high as 98% above 35% among the present invention, takes away a large amount of heats during because of water evaporates, thereby ignition temperature is played inhibitory action.With traditional water identical effect is arranged.2, combustible is wrapped to form does not fire layer: the present invention is in the combustible overwrite procedure; combustible is formed protective layer; under the situation of the complete evaporate to dryness of moisture content; the remaining incombustible material that is mainly; inorganic material generally can be more than high temperature resistant 200 degree; even run into high temperature, can not burn yet, still can form not flame-proofing protective layer on right thing surface.3, air-isolation: in oil product ignition control compound fire extinguishing, because this material proportion can control, so when controlling to proportion less than the fluent material of required fire extinguishing, it can float at liquid surface, thereby plays the air insulating effect, plays the fire extinguishing effect.4, the non-flammable compressive gas that a large amount of water vapour and other inserts discharged under high-temperature condition also can play certain dilution, buffer action to air.
The prepared material of the present invention is slurry or colloid, can adopt direct conveying of pump housing materials such as underflow pump, gear pump or manpower to splash; Also can adopt concrete delivery truck to transport at a distance; Carry and the high-altitude conveying with pump truck is remote; Fire fighting truck sprays; Spray in the aircraft high-altitude or mode such as high-altitude delivery is delivered near the burning things which may cause a fire disaster or in the burning things which may cause a fire disaster.
The present invention compared with prior art has the following advantages:
