Product Details

I. Fire Extinguishing Principle

1. Gas-phase chemical inhibition: Under the action of heat, gasified metal ions or electroless cations decomposed in fire extinguishing aerosols can react affinity with active groups in combustion, consume a large number of active groups repeatedly, and reduce combustion free radicals.
2. Solid-phase chemical inhibition: the particle size of fire extinguishing aerosol is very small (0.001~100μm), and it has a large surface area and surface energy. It can adsorb the active groups in combustion, and has biochemical effects. It consumes a large number of active groups and reduces combustion free radicals.
3. Reducing oxygen concentration: N2 and CO2 in fire extinguishing aerosols can reduce oxygen concentration in combustion, but their speed is slow, and the fire extinguishing effect is far less than endothermic cooling and chemical inhibition.
II. Main Advantages
It has the advantages of high efficiency, fast speed, non-toxicity, no destruction of the ozone layer, simple structure, no occupation or small area, convenient installation and low cost.
