1, product characteristics: carbon dioxide fire extinguisher, mainly rely on the role of asphyxiation and part of the cooling effect of fire, carbon dioxide has a high density, about 1.5 times the air. Under normal pressure, liquid carbon dioxide will vaporize immediately, and generally 1KG of liquid carbon dioxide can produce about 0.5 cubic meters of gas. Therefore, when extinguishing fire, carbon dioxide gas can exclude air and surround the surface of the burning object or distribute in a relatively closed space, reduce the oxygen concentration around the combustible or in the protective space, and cause suffocation to extinguish the fire. In addition, when the carbon dioxide is ejected from the storage container, it will be rapidly excited into gas by the liquid, and absorb part of the heat from the surrounding, and play a cooling role. After the fire does not pollute the substance, leaving no trace. 2. Scope of application: It has excellent properties such as good fluidity, high injection rate, non-corrosive containers and non-deterioration. It is used to extinguish initial fires of books, archives, valuable equipment, precision instruments, electrical equipment below 600 volts and oil. It can also be applied to Class A fires, but it cannot extinguish fires of flammable and flammable liquids with water depth in Class B, nor can it extinguish fires of live equipment and Class C and D lamps.
