1. Blocking oxygen: The bicarbonate contained in the fire extinguishing agent generates carbon dioxide when it is heated, and carbon dioxide blocks the burning.
The contact of the burnt surface with oxygen suppresses the occurrence of combustion.
2, inhibit chemical chain reaction: the ammonium phosphate contained in the fire extinguishing agent and the main fire extinguishing agent react to produce ammonia gas,
Ammonia can form a negative catalyst for the combustion chain reaction.
3. Cooling effect: The fire extinguishing liquid is scattered from the resin bottle that is thrown to the vicinity of the fire source. At this time, due to moisture moment
Evaporation causes the combustion to cool rapidly.
4, to prevent re-ignition: ammonium sulfate in the fire extinguishing agent can increase the burning point of the burning material, fundamentally eliminate the re-ignition
The possibility.
