超細干粉滅火技術是當今高能效的滅火技術之一，由于滅火迅速，且對應用場所的密封性沒有要求，可以適用于全封閉空間、半封閉空間以及開方式空間的火災保護。

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.

與普通干粉滅火劑相比，超細干粉滅火劑粒徑小、表面積大，具有高能效滅火、不吸潮、不結塊，對保護對象不造成任何影響、綠色等特點。那么川消超細干粉滅火裝置是如何實現高能效滅火的呢？

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?

這要從它的滅火原理來分析，超細干粉通過化學滅火和物理滅火相結合的方式實施滅火，主要有以下特點：

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、對有焰燃燒的強抑制作用

1、 Strong inhibitory effect on flame burning

有焰燃燒是一種鏈式反應。燃料分子在燃燒的高溫下或其形成的能量作用下被活化，在氧的存在下產生自由基或活性基因，并靠這些具有高能量的自由基傳播反應，維持燃燒的持續進行。超細干粉與火焰混合時，發生分解反應，迅速消耗燃燒自由基，使自由基消耗的速度大于生產的速度，鏈式反應鏈中斷，火焰迅速熄滅。

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、對表面燃燒強窒息作用

2、 Strong suffocation effect on surface combustion

超細干粉對撲滅有焰燃燒有很好的速率和效率，而且對一般固體物質的表面燃燒（陰燃）有很好的熄滅作用。當超細干粉晶體粉體與灼燒的燃燒物表面接觸時，發生一系列化學反應，在固體表面的高溫作用下被熔化并形成一個玻璃狀覆蓋層將固體表面與周圍空氣隔開，使燃燒窒息。

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、對熱輻射的遮隔和冷卻作用

3、 Shielding and cooling effects on thermal radiation

使用超細干粉滅火時，超細干粉的粉霧與火焰相混合，可降低燃燒物的輻射熱，同時受熱分解，產生吸熱作用，可吸收火焰的部分熱量，抑制燃燒。

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、對氧濃度的稀釋作用

4、 Dilution effect on oxygen concentration

使用超細干粉滅火過程中，分解產生的一些不活性氣體如：二氧化碳、水蒸氣等，對燃燒區的氧濃度具有稀釋作用，使火的燃燒反應減弱，破壞物體的燃燒條件，燃燒停止。

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，超細干粉滅火劑對大氣臭氧層耗減潛能值（ODP）為零，溫室效應潛能值(GWP)為零，對人體皮膚和呼吸道無刺激，對保護物無腐蝕，無害。對此，您還有什么事項就來我們網站http://www.xintli.net咨詢吧！

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.
