Fire Extinguisher Ball

What is the fire extinguishing principle of a fire extinguisher ball?

The fire extinguisher ball device consists of a foam shell, an internal dry powder drive device, and ABC dry powder extinguishing agent. When the external fuse is ignited, the driving medium is activated and the shell rapidly expands and ruptures. The dry powder extinguishing agent is rapidly sprayed to the protected area and quickly diffuses around to form a fully submerged fire extinguishing state, and the flame is extinguished under the dual physical and chemical effects of the dry powder extinguishing agent. The basic principle of fire extinguisher ball extinguishing actually integrates the four methods mentioned above. First, the dry powder isolates the combustible material and combustible material, destroying the possibility of continuous combustion; secondly, the dry powder isolates the combustible material and air, so that the combustible material is isolated from oxygen and cannot continue to burn; then, the dry powder will react at high temperatures, not only to absorb heat but also to form salt and water to reduce the temperature of the combustible material, so that the temperature of the combustible material is reduced to below the ignition point; finally, the dry powder is in contact with the combustible material, inhibiting the combustible factors. To sum up, the fire extinguisher ball has a good fire extinguishing effect and can prevent the flame from reigniting to a large extent.
