Electronically controlled superfine dry powder fire extinguishing device : Superfine dry powder fire extinguishing agent, GA578-2005 "Superfine dry powder fire extinguishing agent" stipulates: BC, ABC superfine dry powder fire extinguishing agent 90% particle size is less than or equal to 20um. At the critical particle size, all the particles of the fire extinguishing agent have an inactivating effect, the dry powder fire extinguishing efficiency is greatly improved, and the amount of use is significantly reduced. When the particle size of the fire extinguishing agent is reduced to 5um, or even 0.5um, the fire extinguishing efficiency rises sharply. The fire extinguishing efficiency is dozens of times the capacity of the conventional fire extinguishing agent, and the amount of use is only a few percent. Main reasons: Ultra-fine dry powder has large surface area, high activity, easy to form uniformly dispersed and suspended in the air, forming a relatively stable aerosol, fast decomposition rate when heated, strong ability to capture free radicals, so the fire extinguishing efficiency has been dramatically improved.
Electronically controlled pressure storage suspension type ultrafine dry powder fire extinguishing device is composed of a cylinder, ultrafine dry powder, a nozzle, a pressure indicator, a temperature-sensitive glass ball, a hanging ring, and an electric starter.
System composition : ultra-fine dry powder fire extinguishing device, gas fire extinguishing controller, fire detector, sound and light alarm, gas release indicator, emergency start and stop button, external power supply, etc. to form a complete automatic fire extinguishing system.
