What are the main components of a fire extinguisher in daily life?
The 1211 main components of fire extinguishing agent machine 1211 is two fluorine monochloromonobromomethane (CF2ClBr), it is a gas at room temperature and atmospheric pressure, the boiling point is 4 DEG. Fire extinguishing agent in a cylinder in compression state. From the liquefaction extinguishing agent cylinder spurting is a mixture of small droplets and vapors with fire extinguishing agent. The combustion contact be heated to produce bromine ion, hydrogen radicals. It produces with combustion, the combustion of the chain reaction quickly stopped, the explosion suppression fire.1211 small peak, the combustible gas is mixed with 6 ~ 7% volume 1211, stop burning. It is especially applicable to extinguish the oil, organic solvent, high voltage electrical equipment and precision instruments. Its fire extinguishing efficiency more than 4 times higher than carbon dioxide, leaving no trace and after the fire.
What can be seen in many places of life is dry powder fire extinguishers.Dry powder fire extinguishing agent is composed of a fire extinguishing material (such as sodium bicarbonate, ammonium carbonate, ammonium phosphate) and the amount of lubricant (magnesium stearate, mica powder, talcum powder, etc.) a small amount of desiccant (silica gel) fine particles mixed together after grinding, as a jet powered by carbon dioxide. The jetted powder concentration dense, fine particles, cover in solid combustion can constitute the isolation layer hinder combustion, and the precipitation is not flammable, so that the oxygen concentration in the air is reduced, the flame is extinguished the fire extinguishing function.8kg injection 14 ~ 18 seconds, a range of about 4.5m. which is suitable for initial fire fighting items oil, combustible gas, electrical equipment wait.
