Description

A kind of multipurpose extinguishing chemical prepared based on modified sodium salt dry powder
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 multipurpose extinguishing chemical prepared by modified sodium salt dry powder.
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 Sodiotartrate 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 warp Dry, crushing, the fire-fighting of mixing micro-solid powder group kind extensively using extinguishing chemical and are mainly used for fire extinguisher except metal fire of putting out a fire to save life and property BC dry powder fire extinguishing agents (sodium acid carbonate) ABC dry powder (sodiotartrate) two class as the outer dry powder fire extinguishing agent of the special dry powdered extinguishing chemical of calamity Free radical is produced with burning journey fuel or property group hairization suppresses negative catalyst and makes pyric chain by dry powder machine salt volatility solution thing The disconnected fire extinguishing of reaction；Two by dry powder powder fall the reaction of combustion things surface outgoingization and the glassy coating isolating oxygen of high temperature action shape layer into The another external dilution oxygen of fire smothering, plays certain cooling effect.Fire foam is a kind of small volume, and surface is by liquid bag The bubble population enclosed, proportion is between 0.001~0.5.Since the proportion of foam is far smaller than the proportion of general flammable liquid, thus The surface of liquid can be floated on, forms a foam blanket.Meanwhile foam has certain viscosity again, can be adhered to The surface of general flammable solid.The foam blanket that fire foam is formed on comburant surface, can make comburant surface and air Isolation.The prior art：Chinese invention patent application, application number：201210236483.6 Publication No.：102772877A, it is open A kind of extinguishing chemical, the extinguishing chemical are made of the raw material of following each component：0.1-0.2 parts of organic silicone oil, 2-3 parts of carbamide, 3.5-4.5 parts of ammonium phosphate, 6.1-6.2 parts of potassium hyperchlorate, 32-35 parts of concentrated latex, 11-12 parts of water.The extinguishing chemical of the present invention, energy The deficiency of general extinguishing chemical is enough made up, cost of manufacture is relatively low, and raw material is easy to get, and the making raw material of extinguishing chemical is harmless, does not have Pollution, securely and reliably.
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, more it is noted that selection extinguishing chemical, so could more preferably, faster, safer stamps out a fire.
