In the preparation method of 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, it is stored in public place or the place of fire may occurs, 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 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, crush, mixing the fire-fighting of micro-solid powder group kind extensively using extinguishing chemical and be mainly used in fire extinguisher except metal fire of putting out a fire to save life and property
BC powder extinguishing agents (sodium acid carbonate) ABC dry powder (sodiotartrate) two class as the outer powder 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 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 dry up
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.Because 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, comburant surface and air can be made
