Description
Technical field
The invention belongs to extinguishing chemical field more particularly to a kind of efficient ABC dry-chemical fire extinguishing compositions.
Technical background
Dry powder fire extinguishing agent is made of one or more subtle inorganic powders with extinguishing ability, and extinguishing mechanism is as follows:
(1) organoselenocyanate: combustion process is a chain reaction process, OH and H free radical is to maintain burning chain anti-
The crucial free radical answered, they have very high energy, and very vivaciously, and the service life is very short, once generation, causes immediately next
Step reaction, generates more free radicals, combustion process is enable to continue and constantly expand.The fire extinguishing component of dry powder fire extinguishing agent is combustion
The inert matter of burning, freedom after dry powder fire extinguishing agent is added to combustion zone being mixed with flame, in dry powder powder M and flame
When base contacts, free radical is instantaneously adsorbed on powder surface, and following reaction occurs:
M (powder)+OH (free radical) → MOH
MOH+H (free radical) → M+H2O
By above-mentioned reaction, by the effect of powder, the free radical OH and H in combustion reaction are consumed.When a large amount of powder
When end sprays to flame with mist, the free radical in flame is largely adsorbed and is converted, and reduces free radical quantity sharply, is caused
Make combustion reaction chain interruption, finally makes fray-out of flame.
(2) buffer action.The solid powder of ejection is covered on comburant surface, constitutes the separation layer for hindering burning.Especially
When powder covers up to certain thickness, can also play the role of preventing re-ignition.
(3) cooling and smothering action.Powder can release the crystallization water at high temperature or decompose, and it is anti-that these belong to heat absorption
Answer, and decompose the inactive gas that generates can dilute combustion region oxygen purity, to play cooling with asphyxia work
With.
3 seed types are broadly divided into according to fire extinguishing type and use occasion, dry powder fire extinguishing agent.(1) ABC powder extinguishing agent is used
In putting out flammable solid, liquids and gases fire；(2) BC dry powder fire extinguishing agent, for putting out flammable liquid and gas fire；(3)D
Class dry powder fire extinguishing agent, for putting out combustible metal class fire.
ABC powder extinguishing agent can put out flammable solid (such as timber) fire that BC dry powder can not be put out, and have fire extinguishing
High-efficient, speed is fast, and raw material sources are extensive, to environment, people and animals' nonhazardous, does not need special power and, stream broad using temperature
It is dynamic that property is good, storage period is long, not moisture-sensitive agglomeration, good insulating the features such as, be widely used.
ABC powder extinguishing agent refers mainly to ammonium phosphate powder extinguishing agent, and monoammonium phosphate (NH4H2PO4) therein is risen main
Fire extinguishing effect, monoammonium phosphate can form inflaming retarding membrane in solid matter surface after spraying into the scene of a fire, thus by combustible and air
In oxygen keep apart with realize fire extinguishing purpose, according to the difference of ammonium phosphate salt content in extinguishing chemical, fire extinguishing effectiveness is
It is different.Ammonium sulfate plays auxiliary fire extinguishing, remaining auxiliary material has grinding aid, moisture-proof agglomeration resistance, increases the functions such as mobility.
The ABC powder extinguishing agent that the country generally produces at present contains 50% or so monoammonium phosphate, 25% or so sulfuric acid
Ammonium, remaining is auxiliary material, and monoammonium phosphate (NH4H2PO4) content for playing main fire extinguishing is obviously relatively low, and extinguishing effect is owed
It is good；On the other hand, it theoretically analyzes, ABC powder extinguishing agent diameter of particle is higher less than the ratio of 0.04mm, fire extinguishing effectiveness
It is higher, but ratio of the ABC powder extinguishing agent manufacturer by diameter of particle less than 0.04mm controls within 50% at present, goes out
Fiery efficiency is low, this is the major defect of current ABC powder extinguishing agent.
Summary of the invention
Efficient ABC powder extinguishing agent of the present invention refers to that main component monoammonium phosphate (NH4H2PO4) content is greater than
75%, the ABC of the sum of monoammonium phosphate (NH4H2PO4) and another main component ammonium sulfate ((NH4) 2SO4) content greater than 90% is dry
Powder extinguishing chemical.This product is that a kind of monoammonium phosphate (NH4H2PO4) content is high, and ratio of the diameter of particle less than 0.04mm is high, fire extinguishing
The high high-efficiency fire-extinguishant of efficiency.
The present invention is using monoammonium phosphate and ammonium sulfate fire extinguishing component, and wherein monoammonium phosphate mass fraction is greater than 75%, phosphoric acid
The sum of monoammonium and ammonium sulfate mass fraction are greater than 90%, and to reach sufficient extinguishing effect, diameter of particle is reasonably distributed, and powder is logical
The ratio for crossing 0.25mm standard screen is 100%, and the ratio between 0.04~0.25mm standard screen is 35~45%, is passed through
The ratio of 0.04mm standard screen is 55~65%；In the powder that the present invention passes through 0.04mm standard screen, monoammonium phosphate mass fraction
Greater than 75%,
Preferably, in the powder by 0.04mm standard screen, the sum of monoammonium phosphate and ammonium sulfate mass fraction are big
In 90%.Active constituent content is high in chassis, good extinguishing effect.
It preferably, further include auxiliary material in dry powder fire extinguishing agent of the present invention, auxiliary material and mass fraction are white carbon black
1.0~2.5%, quartz sand 1.2~2.6%, silicone oil 0.5~0.9%, mica 1.2~2.5%, atlapulgite 1.2~2.0%,
