[Features]: Ultra-fine dry powder has a large surface area, high activity, easy to form uniformly dispersed and suspended in the air, and forms a relatively stable aerosol. It decomposes quickly when heated, has strong ability to capture free radicals, and has a dramatic improvement in fire extinguishing efficiency.
[System composition]: Temperature-controlled storage pressure hanging superfine dry powder fire extinguishing device is composed of a cylinder, superfine dry powder, a nozzle, a pressure indicator, a temperature-sensitive glass ball, and a ring.
：在GA578-2005«超细干粉灭火剂»规定：BC 、ABC超细干粉灭火剂90%粒径小于等于20um.当干粉灭火剂粒径小于临界粒径时，灭火剂粒子全部起灭活作用，干粉灭火效能大大提高，用量明显减少。 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. When the dry powder fire extinguishing agent particle size is less than the critical particle size, All play an inactivating role, the dry powder fire extinguishing efficiency is greatly improved, and the dosage 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.
：温控贮压悬挂式超细干粉灭火装置由筒体，超细干粉，喷头，压力指示器，感温玻璃球，吊环组成。 System composition : Temperature-controlled storage and pressure-suspended ultra-fine dry powder fire extinguishing device consists of a cylinder, ultra-fine dry powder, a nozzle, a pressure indicator, a temperature-sensitive glass ball, and a ring. The cylinder is filled with low-pressure nitrogen. When the ambient temperature reaches the temperature setting value of the temperature-sensitive glass bulb, the glass bulb bursts, and the valve is opened to release the fire extinguishing agent, thereby achieving the purpose of extinguishing the fire.
