Fire Extinguisher 2kg-9kg Product Feature
High Efficiency: Fire extinguishing powder extinguishes fires quickly, effectively controlling and extinguishing them in a short period of time. It is particularly effective in early-stage fires.
Portability: Fire extinguishing powder is typically contained in fire extinguishers, which are compact and lightweight, making them easy to carry and move, allowing for quick access and initial extinguishing of fires.
Storage Stability: Fire extinguishing powder is chemically stable and can withstand long-term storage under appropriate conditions (such as dry, well-ventilated conditions, and out of direct sunlight). Its shelf life is typically 5-10 years.
Wide Temperature Range: Fire extinguishing powder maintains effective extinguishing performance in both high and low temperature environments, making it suitable for both cold regions and high-temperature workplaces.
Fire extinguishing powder fire extinguishing principle
Chemical inhibition: The active ingredient decomposes at high temperatures to produce free radicals, which combine with active free radicals in the combustion chain reaction, directly interrupting the combustion reaction.
Smothering and isolation: The powder covers the surface of the burning material, isolating it from oxygen; the inert gas produced by decomposition further dilutes the oxygen concentration.
Auxiliary cooling: The powder spraying and decomposition process absorbs some heat, reducing the temperature of the burning material.
What is the main ingredient of this fire extinguishing powder? What types of fires is it suitable for?
Our fire extinguishing powder is made of ammonium dihydrogen phosphate (ABC type), with some special versions containing auxiliary ingredients such as ammonium sulfate. It is suitable for Class A (solid fires, such as wood and cloth), Class B (liquid fires, such as gasoline and diesel), and Class C (gas fires, such as natural gas and coal gas), quickly suppressing the spread of flames and interrupting the combustion chain.
What is the shelf life of the fire extinguishing powder? What precautions should be taken during storage?
The shelf life is 5 years when sealed. Once opened, use within 1 year. Store away from direct sunlight and high temperatures (no more than 40°C). Keep away from humid areas (relative humidity ≤ 80%), and avoid stacking to a height of no more than 3 meters to prevent the packaging from being crushed and causing the powder to clump.
