Abstract
The invention relates to a special foam extinguishing agent for F-class fire. The special foam extinguishing agent consists of the following components in percentage by mass: 40-70 percent of alkali metal salt, 0.1-0.5 percent of a stabilizer, 3-5 percent of an anti-freezing agent, 1-3 percent of a solubilizer and the balance of water. According to the special foam extinguishing agent for the F-class fire, on the basis of the fire extinguishing performance, all the used raw materials are environmentally friendly, non-toxic and safe to use; the special foam extinguishing agent is a safe and environment-friendly green product and is suitable for prevention and extinguishing of F-class fire (fire on cooking substances (such as animal and plant oil) in cookware).
Description
Technical field
The present invention relates to the special fire foam of a kind of F class fire, belong to fire-fighting consumptive material technical field.
Background technology
F class fire, namely betides the vegetable oil in cooking apparatus or animal oil fire.The fire caused by culinary art is that countries in the world family meets with maximum condition of a fire always, and it is also the arch-criminal causing house person injured equally.Culinary art oil is on fire is the main cause of cooking fire.Because oil firing produces high temperature, people is difficult to close, if gone out with water, can encourage the intensity of a fire and propagate and worsen the condition of a fire, very easily resume combustion again after putting out, the therefore wayward condition of a fire, be the most difficult fire put out.
Conventional fire foam, powder extinguishing agent and CO2 extinguishing chemical all can not put out this kind of fire effectively.Adopt traditional extinguishing chemical to go out foam that F class concrete on fire produces also is not reduced to below self-ignition point just froth breaking in oil temperature, causes putting out a fire.Therefore, F class of going out fire can only lean on automatic spray, even completes primarily of fire brigade.Domesticly at present not yet find that there is the special extinguishing chemical being applicable to F class fire.
Summary of the invention
The technical problem that the present invention solves is to provide the special fire foam being applicable to prevention and F class fire of putting out a fire to save life and property of a kind of safety, environmental protection.
In order to solve the problems of the technologies described above, the invention provides the special fire foam of a kind of F class fire, the component comprised and mass percentage content thereof are:
Being preferably of technique scheme:
The component that described fire foam comprises and mass percentage content thereof are:
Being preferably further of technique scheme:
The component that described fire foam comprises and mass percentage content thereof are:
Being preferably further of technique scheme: described alkali metal salt is the composition of potash, potassium acetate.
Being preferably further of technique scheme: the mass ratio of described potash, potassium acetate is 1: 3 to 1: 0.5.
Being preferably further of technique scheme: the mass ratio of described potash, potassium acetate is 1: 1.
Being preferably further of technique scheme: described stabilizing agent is sodium alginate or xanthans.
Being preferably further of technique scheme: described antifreeze is ethylene glycol or glycerine.
Being preferably further of technique scheme: described solubilizer is urea.
The special fire foam of F class fire of the present invention adopts conventional production method, first stabilizing agent and water is carried out predissolve, after again alkali metal salt, antifreeze, solubilizer and water are added in proportion, mix.
The present invention creatively introduces alkali metal salt component, and by the complementary compatibility with antifreeze, solubilizer and stabilizing agent, extinguishing property is good.In the basic conditions, can there is saponification (Saponification) in ester and alkali metal salt, and the extinguishing chemical utilizing this principle to make is very effective to edible oil fire, is also to put out a fire to save life and property the extinguishing chemical of edible oil fire mature and reliable the most at present.These alkali metal salts are added to the water by a certain percentage, can extinguishing chemical be formed.When this kind of extinguishing chemical puts on deep fat face, possess certain cooling, cooling effect, particularly under the effect of overflowing gas and soap in a large number, a froth bed can be formed, thus isolated air and high-temperature edible oil, and limit the evaporation of high-temperature oil gas, thus play the effect of fire extinguishing.
Beneficial effect of the present invention:
(1) the special fire foam product of F class fire of the present invention is domestic initiation at present, and all researching and developing this series products energetically both at home and abroad at present, is the irreplaceable products of other fire foams.
(2) safety, environmental protection, use safety: F class extinguishing chemical is applicable to kitchen, product of the present invention, on the basis ensureing extinguishing property, guarantees the equal environmental protection of raw materials, nontoxic, use safety, because of but a kind of name environment-friendly product.
(3) the special fire foam of F class fire of the present invention, is mainly used in the prevention of F class fire and puts out a fire to save life and property.
