1. Ultra-fine dry powder high efficiency fire extinguishing agent is a combination of chemical and physical fire extinguishing method, so it solves the problem of slow fire extinguishing speed and low fire extinguishing efficiency existing in physical fire extinguishing.
The extinguishing concentration of ultra-fine dry powder extinguishing agent is 64.4g/m3, which is the lowest extinguishing concentration, the highest extinguishing efficiency and the fastest extinguishing speed among the extinguishing agents invented at home and abroad. The extinguishing efficiency per unit volume is 2-3 times of halon extinguishing agent, 6-10 times of common dry powder extinguishing agent, more than 10 times of sevoflurane extinguishing agent, and 15 times of carbon dioxide.
2. Ultra-fine dry powder highly effective extinguishing agent has strong inhibition on flame combustion.
Flame burning is a chain reaction. Fuel molecules are activated at the high temperature of combustion or under the action of the energy they form. Free radicals or active genes are generated in the presence of oxygen, and these high-energy free radical propagation reactions maintain the continuous combustion. When the ultrafine dry powder is mixed with the flame, the fire-extinguishing components quickly capture the combustion free radicals, making the rate of free radicals consumption greater than that of production, the combustion free radicals are quickly exhausted, the chain reaction process is terminated, and the flame is quickly extinguished.
3. Ultra-fine dry powder highly effective extinguishing agent has strong asphyxiating effect on surface combustion.
Ultrafine dry powder has a good rate and efficiency to extinguish flame combustion and has a good extinguishing effect on surface combustion (smouldering) of general solid materials. When the ultrafine dry crystal powder comes into contact with the surface of the burning combustor, a series of chemical reactions take place. Under the action of the high temperature of the solid surface, it is melted and forms a vitreous covering layer to separate the solid surface from the surrounding air, suffocating the combustion.
4. Ultra-fine dry powder highly effective fire extinguishing agent has shielding and cooling effect on thermal radiation.
When using ultrafine dry powder to put out a fire, thick cloud like powder and flame mix, decompose endothermic reaction, can absorb part of the heat of flame, some of the inactive gases produced by these decomposition reaction, such as: carbon dioxide, water vapor, etc., have dilution effect on the oxygen concentration in the combustion area, so that the fire combustion reaction weakened.
5. Ultrafine dry powder extinguishing agent can realize complete annihilation.
Ultra-fine dry powder extinguishing agent can realize total submergence extinguishing because of its small particle size, light weight, good fluidity, ability to suspend in the air for a certain time, and its heat drive property. This is the only dry powder extinguishing agent that can realize total submergence extinguishing. It can put out a fire anywhere in a protected area.
6. Super fine powder automatic fire extinguishing device is easy to install and use.
Super fine powder automatic fire extinguishing device is easy to install, low work volume, no need to perforate through the wall, install a large number of pipes and auxiliary facilities. The device only needs to be suspended above the protected object. It has three starting modes and reliable performance.
