Description

technical field [0001] The invention relates to a metal dry powder fire extinguishing agent. Background technique [0002] With the continuous development and progress of science and technology, the raw materials and procedures of our life and industrial production have made great progress compared with the past. Special metal raw materials such as potassium, titanium, magnesium, sodium and lithium, and alkylaluminum catalysts have also become very important parts in people's lives and production. The fires caused by the above substances are called metal fires. This kind of fire is a very rare and special kind of fire caused by the combustion of metal substances. A large number of casualties, it is quite difficult to extinguish. [0003] For metal fires, non-combustible materials such as dry sand, diatomaceous earth, graphite or vermiculite powder are traditionally used to cover or absorb them to block combustion. [0004] In the existing fire fighting system, whether it ...

Problems solved by technology

[0005] In the prior art, Class D dry powder fire extinguishing agents are generally divided into two categories, one is the special type, which is only suitable for certain or certain types of metal fires, and the applicable area is relatively small, but the fire extinguishing efficiency is often high

The second is the general-purpose type, which has a wider range of applications, but has problems such as fire extinguishing speed and resurgence resistance, especially after extinguishing the fire, resurgence is easy to occur, and the site is difficult to clean up
