Tel: 021-63574251 15900885584 Fang welcome you to inquire! Carbon dioxide fire extinguishing agent is a hundred years of history of fire extinguishing agent, inexpensive to acquire, easy preparation, which mainly depends on the role and part of the cooling effect of suffocation fire. Carbon dioxide has a high density of about 1.5 times that of air. At atmospheric pressure, the carbon dioxide will be immediately vaporized liquid, generally produce 1kg of liquid carbon dioxide of about 0.5 cubic meters of gas. Thus, when fire, carbon dioxide gas can be ruled out in the combustion air to surround the object surface or distributed in relatively confined space, reducing the oxygen concentration of combustible materials around or inside the protected space, resulting in suffocation and fire. In addition, carbon dioxide is discharged from the storage container, it would quickly vaporize into a gas from a liquid, and absorb some of the heat from the surroundings, play a role in cooling. Scope has good liquidity, injection rate, non-corrosive and non-perishable container and other fine performance, to extinguish books, archives, valuable equipment, precision instruments, beginning of the fire 600 volts electrical equipment and oils. Class B for fighting fires, (such as kerosene, diesel oil, crude oil, methanol, ethanol, asphalt, paraffin fire.) Suitable for fighting class C fires (such as coal, natural gas, methane, ethane, propane, hydrogen, etc. fire.) Fighting Class E fire (charged object burning fire).
