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 base specifically
In the fire foam of acid solution.
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 the place of fire may occur, filling in different types of fire extinguisher
Component it is different, be to aim at different fire alarms and set.It must be noted that during use in order to avoid producing minus effect and causing danger.
Existing extinguishing chemical mainly has two kinds of a foam and dry powder, and two kinds of extinguishing chemicals respectively have a quality, going out in dry powder extinguisher
Dipotassium hydrogen phosphate salt is filled in fiery agent to be used to put out a fire dry and be easy to flow attritive powder by tool fire extinguishing effectiveness machine salt a small amount of additive
Extensively using extinguishing chemical and it is mainly used for fire extinguisher except metal of putting out a fire to save life and property through drying, crushing, the fire-fighting of mixing micro-solid powder group kind
BC dry powder fire extinguishing agents (sodium acid carbonate) ABC dry powder (dipotassium hydrogen phosphate salt) as the outer dry powder fire extinguishing agent of the special dry powdered extinguishing chemical of fire
Two classes produce free radical with burning journey fuel by dry powder machine salt volatility solution thing or property group hairization suppresses negative catalyst and makes combustion
Chain reaction is burnt to break fire extinguishing；Two fall the outgoingization reaction of combustion things surface and the glassy coating isolation of high temperature action shape layer by dry powder powder
Oxygen plays certain cooling effect into the another external dilution oxygen of fire smothering.Fire foam is a kind of small volume, and surface is by liquid
The bubble population that body surrounds, proportion is between 0.001~0.5.Since the proportion of foam is far smaller than the proportion of general flammable liquid,
The surface of liquid can be thus floated on, forms a foam blanket.Meanwhile foam has certain viscosity again, can glue
Invest the surface of general flammable solid.The foam blanket that fire foam is formed on comburant surface, can make comburant surface with
Air insulated.
