The invention discloses an epoxypropane dedicated foam fire extinguishing agent; a polysaccharide polymer and a fluorine-containing polysaccharide polymer are matched in the fire extinguishing agent, so that the disadvantage that a traditional fire extinguishing agent cannot effectively save fire disasters of low-boiling-point polar flammable liquids is overcome, and security assurance is provided for development of research, production and storage of the low-boiling-point water-solubility flammable liquids in China.
Description
Technical field
The invention belongs to a kind of technical field of fire control, relate to a kind of fire foam, the special fire foam of especially a kind of expoxy propane class.
Background technology
Society, fire is common disaster, causes grave danger to the people's lives and property, and increasing extinguishment product is developed endlessly.Common extinguishing chemical comprises above-water method agent, powder extinguishing agent, the products such as fire foam.Wherein, fire foam is mainly used in laboratory, chemical enterprise, oil field, oil depot, the occasions such as oil plant, and the proportion due to foam is less than general flammable liquid, floats on flammable liquid surface and forms froth bed.Rely on the covering effect of froth bed to make comburant surface realize fire smothering effect with air insulated, burning things which may cause a fire disaster is put out rapidly to Initial Stage of Fire or stops the expansion of the intensity of a fire to play huge effect.
Facts have proved, low boiling water-soluble burnable liquid easily evaporates, saturated vapour pressure is higher, and there is very strong polarity, when use traditional water-resistant foam extinguishing chemical to low boiling water-soluble burnable liquid fire go out rescue time, the water of water-soluble burnable liquid very easily in foam is combined and separates out, the closure of foam is deteriorated, flammable liquid steam is caused to penetrate froth bed easily, and in foam surface flash burn, froth bed cannot play to low boiling flammable liquid the smothering effect covering isolation, and extinguishing effect is very poor.This production for the flammable product of low boiling, use, storage and transport bring great potential safety hazard.Therefore, the research direction that a kind of fire foam effectively can putting out a fire to save life and property low boiling water-soluble burnable liquid fire is Fire Escape both at home and abroad is at present studied
Summary of the invention
The present invention, for solving the problems of the technologies described above, have developed a kind of for low boiling water-soluble burnable liquid, especially for the special fire foam of expoxy propane (boiling point is 34 DEG C).
Concrete technical scheme of the present invention is as follows:
The special fire foam of a kind of expoxy propane, comprises the components such as blowing agent, stabilizing agent, visbreaking agent, cosolvent, water, it is characterized in that in fire foam, add polysaccharide polymer or fluorine-containing polysaccharide polymer.
Polysaccharide polymer and fluorine-containing polysaccharide polymer belong to polysaccharide, and glycocalix adds in water can not form genuine solution, but form colloid mixed liquor.In extinguishing chemical, add the technique effect that polysaccharide polymer and fluorine-containing polysaccharide polymer produce is: extinguishing chemical foam generated while, form one deck glued membrane between froth bed surface and expoxy propane liquid; what this layer of glued membrane had intercepted expoxy propane liquid and froth bed moisture directly contacts and combination and precipitation; significantly promote the anti-polarity of extinguishing chemical foam; guarantee that expoxy propane steam cannot penetrate froth bed; ensure that the coverage effect of froth bed to expoxy propane, thus reach the technique effect of froth bed to burning things which may cause a fire disaster fire smothering.
The technical scheme of further improvement is: in the special fire foam of described expoxy propane, select APG as the blowing agent of extinguishing chemical.
Polysaccharide polymer, fluorine-containing polysaccharide polymer is with the addition of in fire foam, although significantly improve the anti-polarity of extinguishing chemical, but the counter productive that simultaneously general foaming performance of foaming agent also can be caused to be deteriorated, the foam that extinguishing chemical produces tails off, slowing of cover ring Ethylene Oxide liquid surface, weakens the effect of fire extinguishing.
APG has the characteristic of conventional nonionic and anion surfactant concurrently, has high surface and good intermiscibility; Foaming characteristic is good, and foaming abundancy is fine and smooth.Through test of many times, when the blowing agent selecting APG as fire foam, can overcome in fire foam, add polysaccharide polymer, counter productive that foam performance that fluorine-containing polysaccharide polymer causes is deteriorated, not only anti-polarity is strong for the foam of generation, and coefficient of foaming is high.
The technical scheme of further improvement is: in the special fire foam of described expoxy propane, add fluorine surfactant.
By taking technique scheme, reduce the surface tension of the foam solution of extinguishing chemical, the foam that extinguishing chemical is produced obtains resistant to elevated temperatures physical characteristic, improves the burn resistance of foam, better covers extinguishing effect to obtain.
The technical scheme further improved is: in fire foam, add polysaccharide polymer, and the mass percent of described polysaccharide polymer in extinguishing chemical is preferably 1%.
The technical scheme further improved is: in fire foam, add fluorine-containing polysaccharide polymer, and the mass percent of described fluorine-containing polysaccharide polymer in extinguishing chemical is preferably 8%.
The technical scheme further improved is: the concentration of described APG in extinguishing chemical is preferably 30%.
The technical scheme further improved is: the concentration of described fluorine surfactant in extinguishing chemical is preferably 8%.
Compared with prior art, technique effect of the present invention is: filled up domestic and international regular-type foam extinguishing chemical and can not effectively to have puted out a fire to save life and property the technological gap of low boiling-point and polarity combustible liquid fire, have developed the special fire foam of expoxy propane class that high, the anti-polarity of a kind of coefficient of foaming is strong, good stability, attack time are short.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be described
Embodiment 1. adopts common water-resistant foam extinguishing chemical and the special fire foam of expoxy propane class to carry out fire attack experiment respectively.
