More Information
Summary:The present invention discloses a cooling type dry powder fire extinguishing agent and a preparation method and application thereof, which belongs to the technical field of fire control. Through a static mixing technology, an aqueous solution and a solid hydrophobic material are dispersed and mixed efficiently to form a cooling type dry powder fire extinguishing agent. The fire extinguishing agent is a micron solid particle of the aqueous solution wrapped by the hydrophobic material microscopically, and is in a dry powder state macroscopically, which can significantly reduce the electrical conductivity of the fire extinguishing agent. Meanwhile, a field rapid preparation method is adopted, which can realize real-time preparation. The preparation method is simple and efficient. The technology can be used for fighting a battery fire, has significant cooling and anti-reignition effects and can avoid the problem of electrical conduction of a traditional water-based fire extinguishing agent.
