Shenzhen Xingwu Fire Fighting Equipment Co., Ltd.

The clean and environmentally friendly hot aerosol automatic fire extinguishing device (hereinafter referred to as the automatic fire extinguishing device) is an environmentally friendly mixed gas fire extinguishing product developed and produced by our company using modern chemical technology. It is non-toxic, non-polluting and non-polluting during the production process. It has high efficiency, low pressure and no residue during the fire extinguishing process. It has no corrosion to the protected objects, strong safety, does not exist, and does not damage the fire-extinguishing process. Atmospheric ozone layer. It is an ideal product to replace halon products in the current fire protection field.
The four elements of combustion are combustibles, oxidants, temperature and uninhibited chain reactions. The fire extinguishing mechanism of fire extinguishing gas is to eliminate one or more of the four elements of combustion.
The solid fire extinguishing agent in the aerosol fire extinguishing device is electrically activated, and undergoes an oxidation-reduction reaction to form a large amount of agglomerated fire extinguishing aerosol. Its main components are nitrogen, a small amount of carbon monoxide, and metal salt solid particles.
The mechanism of aerosol fire extinguishing is as follows
Mechanism of endothermic cooling fire extinguishing
Metal salt particles absorb a large amount of heat at high temperatures, causing physical endothermic processes such as hot melting and gasification, and the flame temperature is affected by The heat radiated to the burning surface of the combustible material for gasification of the combustible molecules and the cracking of the gasified combustible molecules into free radicals will be reduced, and the combustion reaction speed will be suppressed to a certain extent.
, fire extinguishing mechanism
, gas phase chemical inhibition. Under the action of heat, the vaporized metal ions or cations that have lost electrons decomposed in the aerosol can undergo affinity reactions with the active groups in combustion, and are repeatedly consumed in large quantities. Active groups reduce burning free radicals.
The particles in solid-phase chemical suppression fire-extinguishing aerosols have a very small particle size (~) and a large surface area and surface energy. They can adsorb active groups in combustion and undergo chemical reactions, consuming a large amount of active groups. group, reducing burning free radicals.
Reduce oxygen concentration Nitrogen and carbon monoxide in aerosols can reduce the oxygen concentration in combustion, but the speed is slow, and the fire extinguishing effect is far less than endothermic cooling and chemical suppression.
