超细干粉灭火技术是当今高能效的灭火技术之一，由于灭火迅速，且对应用场所的密封性没有要求，可以适用于全封闭空间、半封闭空间以及开方式空间的火灾保护。

Ultra fine dry powder fire extinguishing technology is one of the most energy-efficient fire extinguishing technologies today. Due to its fast extinguishing speed and no requirement for the sealing of the application site, it can be used for fire protection in fully enclosed, semi enclosed, and open spaces.

与普通干粉灭火剂相比，超细干粉灭火剂粒径小、表面积大，具有高能效灭火、不吸潮、不结块，对保护对象不造成任何影响、绿色等特点。那么川消超细干粉灭火装置是如何实现高能效灭火的呢？

Compared with ordinary dry powder fire extinguishing agents, ultrafine dry powder fire extinguishing agents have small particle size, large surface area, high energy efficiency fire extinguishing, no moisture absorption, no agglomeration, no impact on protected objects, and are environmentally friendly. So how does the Chuanxiao ultrafine dry powder fire extinguishing device achieve high energy efficiency fire extinguishing?

这要从它的灭火原理来分析，超细干粉通过化学灭火和物理灭火相结合的方式实施灭火，主要有以下特点：

This needs to be analyzed from its fire extinguishing principle. Ultrafine dry powder is used to extinguish fire through a combination of chemical and physical methods, with the following main characteristics:

一、对有焰燃烧的强抑制作用

1、 Strong inhibitory effect on flame burning

有焰燃烧是一种链式反应。燃料分子在燃烧的高温下或其形成的能量作用下被活化，在氧的存在下产生自由基或活性基因，并靠这些具有高能量的自由基传播反应，维持燃烧的持续进行。超细干粉与火焰混合时，发生分解反应，迅速消耗燃烧自由基，使自由基消耗的速度大于生产的速度，链式反应链中断，火焰迅速熄灭。

Flame combustion is a chain reaction. Fuel molecules are activated at high temperatures during combustion or under the action of the energy they form, producing free radicals or active genes in the presence of oxygen, and relying on these high-energy free radicals to propagate reactions, maintaining the continuous progress of combustion. When the superfine dry powder is mixed with the flame, Chemical decomposition occurs, and the combustion free radical is rapidly consumed, so that the free radical consumption rate is greater than the production rate. The chain reaction chain is interrupted, and the flame is quickly extinguished.

二、对表面燃烧强窒息作用

2、 Strong suffocation effect on surface combustion

超细干粉对扑灭有焰燃烧有很好的速率和效率，而且对一般固体物质的表面燃烧（阴燃）有很好的熄灭作用。当超细干粉晶体粉体与灼烧的燃烧物表面接触时，发生一系列化学反应，在固体表面的高温作用下被熔化并形成一个玻璃状覆盖层将固体表面与周围空气隔开，使燃烧窒息。

Ultra fine dry powder has a good rate and efficiency in extinguishing flame combustion, and has a good extinguishing effect on surface combustion (smoldering) of general solid substances. When the ultrafine dry powder crystal powder comes into contact with the surface of the burning substance, a series of chemical reactions occur, which are melted under the high-temperature action of the solid surface and form a glassy covering layer to separate the solid surface from the surrounding air, causing combustion to suffocate.

三、对热辐射的遮隔和冷却作用

3、 Shielding and cooling effects on thermal radiation

使用超细干粉灭火时，超细干粉的粉雾与火焰相混合，可降低燃烧物的辐射热，同时受热分解，产生吸热作用，可吸收火焰的部分热量，抑制燃烧。

When using ultra-fine dry powder for fire extinguishing, the powder mist of ultra-fine dry powder is mixed with the flame, which can reduce the radiation heat of the combustion material. At the same time, it decomposes when heated, producing an endothermic effect that can absorb some of the heat of the flame and suppress combustion.

四、对氧浓度的稀释作用

4、 Dilution effect on oxygen concentration

使用超细干粉灭火过程中，分解产生的一些不活性气体如：二氧化碳、水蒸气等，对燃烧区的氧浓度具有稀释作用，使火的燃烧反应减弱，破坏物体的燃烧条件，燃烧停止。

During the process of using ultrafine dry powder to extinguish fires, some inactive gases such as carbon dioxide, water vapor, etc. generated by decomposition have a diluting effect on the oxygen concentration in the combustion zone, weakening the combustion reaction of the fire, damaging the combustion conditions of the object, and stopping combustion.

此外，超细干粉灭火剂对大气臭氧层耗减潜能值（ODP）为零，温室效应潜能值(GWP)为零，对人体皮肤和呼吸道无刺激，对保护物无腐蚀，无害。对此，您还有什么事项就来我们网站http://www.cx-fire.com咨询吧！

In addition, ultrafine dry powder fire extinguishing agents have zero ozone depletion potential (ODP) and zero greenhouse effect potential (GWP) in the atmosphere. They are non irritating to human skin and respiratory tract, non corrosive to protective materials, and non-toxic and harmless.
