Description
Technical field
The present invention relates to fire-fighting quipment field, the extinguishing chemical field more particularly, to put out a fire is a kind of tool specifically
There is the preparation method of the extinguishing chemical of discrete adhesive force.
Background technology
Fire extinguisher is a kind of portable Fire extinguisher.Chemical substance is placed in fire extinguisher, to rescue fire extinguishing calamity.Fire extinguisher is
One of common fireproofing installation, is stored in public place or may occur the place of fire, is loaded in different types of fire extinguisher
Composition it is different, be to aim at different fire alarms and set.It must be noted that when using in order to avoid producing minus effect and causing danger.
Existing extinguishing chemical mainly has two kinds of foam and dry powder, and two kinds of extinguishing chemicals respectively have going out in quality, dry powder extinguisher
Ammonium phosphate salt is filled in fiery agent to be used to put out a fire dry and is easy to stream attritive powder by tool fire extinguishing effectiveness machine salt a small amount of additive through dry
It is dry, crush, mixing micro-solid powder group kind fire-fighting extensively using extinguishing chemical and is mainly used in fire extinguisher except metallic fires of putting out a fire to save life and property
BC powder extinguishing agents (sodium acid carbonate) ABC dry powder (ammonium phosphate salt) two class as the outer powder extinguishing agent of special dry powdered extinguishing chemical is made dry up
Powder machine salt volatility solution thing produces free radical with burning journey fuel or property group hairization suppresses negative catalyst and makes combustion chain reaction
Disconnected fire extinguishing；Two make that powder powder falls the outgoing reaction of combustion things surface and the glassy coating isolating oxygen of high temperature action shape layer enters asphyxia dry up
Put out a fire another external dilution oxygen, play certain cooling effect.Fire foam is a kind of small volume, what surface was surrounded by liquid
Bubble population, proportion is between 0.001~0.5.Because the proportion of foam is far smaller than the proportion of general flammable liquid, thus can be with
The surface of liquid is floated on, a foam blanket is formed.Meanwhile, foam has certain viscosity again, can adhere to general
The surface of flammable solid.The foam blanket that fire foam is formed on comburant surface, can make comburant surface and air insulated.
Different due to occurring the condition of a disaster of fire in actual life, the fire that different materials occurs not only wants specific aim
Selection fire-extinguishing apparatus, so could be more preferable more it is noted that selection extinguishing chemical, faster, safer stamps out a fire.Therefore, carry
Above-mentioned fire-fighting safety is prepared for one kind reliably, and the method meaning of the extinguishing chemical of efficiency high is extremely important.
