Jinshan Industrial Zone extinguisher factory direct wholesale price annual maintenance of fire extinguishers filled

Jinshan Industrial Zone factory direct fire extinguishers | extinguisher maintenance inspection filling shoots Jiang wholesale Shanghai Fire Equipment Factory set locally and abroad and the company's major manufacturers of fire equipment wholesale agents, sales, maintenance, service in one, the company has a professional management qualification . The main wholesale sales of all types of fire equipment, the company can undertake all sizes of fire engineering. Extinguishing powder extinguishing agent is the core component, it is possible to play the role of fire-fighting substances are mainly: K2CO3, KHCO3, NaCl, KCl, (NH 4) 2S O 4, NH 4H 2S O 4, N a HCO 3, K4Fe (CN ) 6 · 3H2O, Na2CO3, at present, the country has produced products are: ammonium phosphate, sodium bicarbonate, sodium chloride, potassium chloride powder extinguishing agent. Each fire there is an upper limit critical particle diameter, particle size less than the critical role of all particles from the fire, is greater than the critical diameter of the particle extinguishing efficiency drastically reduced, but the momentum of large, small particles through the air to generate aerodynamic Rally, forcing small particles, followed by flames toward the center, and not yet reached the flame was blown away by hot air, reducing the efficiency of fire. Common powder extinguishing agent particle size between 10 ~ 75 μm, such particles diffuse poor, relatively small surface area. Thus, the quantitative powder has a surface area than small, large single particle mass, settling velocity faster, when thermal decomposition is slow, resulting in a smaller ability to capture free radicals, so fire-fighting capability is limited, to some extent limit the use of dry powder extinguishing agent. Powder extinguishing agent particle size directly related to its efficacy fire extinguishing critical component of the larger particle size, the better the effect the fire. Therefore, preparation space can be uniformly dispersed in the fire, suspension of ultrafine powder extinguishing ensure the constituent particles of fire activity, reduce the unit amount of space extinguishing agents are very effective means of fire extinguishing powder to improve efficiency.
