Xi'an carbon dioxide fire extinguisher is mainly used for fighting valuable equipment, archives, instrumentation, 600 volts of electrical equipment and oil since the beginning of the fire. In use, should first be referred to the fire extinguisher location Xi'an fire equipment, fire extinguishers down, pull the pin, one hand holding the megaphone root handle and the other hand grip pressure to open and close the valve.

Powder extinguishing agent, mainly through mists action under the pressurized gas discharged into contact with the flame, physics, chemistry occurs when mixed fire: first by dry powder of inorganic volatile decomposition products, fuels and combustion process generate free radicals or reactive groups on chemical suppression and vice catalytic combustion chain reaction interruption fire; the second is by dry powder falls on combustible surface, the chemical reaction of fire equipment image, and at high temperature form a glassy coating layer, and thus cut off oxygen, and then suffocate the fire. In addition, there are some dilution of oxygen and cooling. Fire Equipment Pictures | Baoji Fire Equipment | Fire [JW] provided by the quality of the first Fire Equipment Co., Ltd. Shaanxi Jiwei.
