Has the dry fire extinguisher done any damage to the environment?

Answer:

The characteristics of fire suppression, such as suffocation, cooling and chemical inhibition of flame burning, are the concentrated expression of extinguishing efficiency of dry powder, in which chemical inhibition is the basic principle of extinguishing fire and plays a major role in extinguishing fire. Dry powder fire extinguishing agent in the fire fighting group is an inactive substance of the combustion reaction when it enters into the combustion zone in the flame, and the free radical generated by the decomposition of the combustion flame produced in the reaction of H and OH and other free radicals react with each other, capture and termination of combustion reaction of free radicals, reducing the rate of combustion reaction. When the concentration of dry powder in the flame is high enough, and the contact area of the flame is large enough, and the rate of free radical stopping is greater than the rate of combustion reaction, the chain combustion reaction is terminated, thus the flame is extinguished. Dry powder extinguishing agent absorbs heat in burning flame and decomposes, because each decomposition reaction is endothermic reaction, so it has better cooling action. In addition, two high temperature decomposition of ammonium hydrogen phosphate, generating glass layer covers on the surface of residues in the solid surface, prevent combustion, and to prevent the resurgence of.
Dry powder fire extinguisher is a kind of fire extinguisher. According to the type of dry powder extinguishing agent, it can be divided into: ordinary dry powder extinguisher; superfine dry powder fire extinguisher.
As long as the use is good, there is no damage, it is a good fire extinguishing tool.
