The fluidity of dry powder fire extinguishing agent has significant influence on fire extinguishing effect. The following is a specific analysis and induction from several aspects:
1.Overlay effect
Dry powder extinguishing agents with good fluidity can spread more quickly and cover the surface of the fire source. For example, the closer the shape of the dry powder particle is to the round, the smoother the surface of the particle, the better the fluidity, and the faster it can cover the fire source.
Good coverage effect can block the contact between oxygen and fire source, inhibit the spread of fire, and improve the fire extinguishing efficiency.
2.Reaction speed
The flow performance of dry powder fire extinguishing agent determines its reaction speed. Dry powder with good fluidity can quickly react with the heat in the flame to form inert gases and salts, which can quickly suppress the flame.
In contrast, dry powder with poor fluidity may have a delay in covering the fire source, resulting in reduced fire suppression effectiveness.
3.Extinguishing agent dosage
Dry powder fire extinguishing agent with good fluidity can be distributed more evenly in the fire extinguishing process and reduce the waste of fire extinguishing agent.
On the contrary, the dry powder with poor fluidity may lead to the accumulation of fire extinguishing agent on the surface of the fire source, increasing the amount of fire extinguishing agent and reducing the fire extinguishing effect.
4.Extinguishing agent residue
The dry powder extinguishing agent with good fluidity can be cleaned up more easily after extinguishing the fire, reducing the impact of the extinguishing agent residue on the equipment and the environment.
Dry chemical powder with poor fluidity may leave a large residue after extinguishing the fire, requiring additional cleanup work.
5.Safety performance
Dry powder fire extinguishing agents with good fluidity are easier to control during use, reducing potential hazards to operators.
Poor flow of dry powder can cause the fire extinguishing agent to form dust clouds during spraying, increasing the health risk for operators.
6.Environmental adaptability
Dry powder fire extinguishing agent with good fluidity can maintain good fire extinguishing performance under different environmental conditions (such as temperature, humidity, etc.).
Dry powder with poor fluidity may be affected by environmental factors, resulting in reduced fire extinguishing effect.
In summary, the fluidity of dry powder fire extinguishing agent has an important influence on the fire extinguishing effect. In order to improve fire extinguishing efficiency and safety, dry powder fire extinguishing agents with good fluidity should be selected to ensure that their performance advantages can be fully utilized during use.
