Most ancient buildings are of wood structure, which is easy to smolder in case of fire. It is a fire that is difficult to occur in class a fire. Most of the ancient buildings in factories and warehouses (especially temples) are covered with wooden tiles with different shapes at the top. A considerable number of ancient buildings such as temples and Taoist temples are located in remote mountainous areas and villages. Due to poor transportation, disrepair and lack of incense, the government's cultural relics management department can't take care of it, or it's just unattended and doesn't use it. Even some of these ancient buildings are listed as national and provincial cultural relics protection units, which has great architectural art and cultural relics protection value. Some of these ancient buildings are even locked and unattended all year round. As long as there is a fire, the consequences are unimaginable.

超细干粉灭火剂对工厂、仓库、古建筑(主要是寺庙)火灾的适用性。超细干粉灭火装置适用性能

Applicability of superfine dry powder fire extinguishing agent to fires in factories, warehouses and ancient buildings (mainly temples). Applicable performance of superfine dry powder fire extinguishing device

以磷酸铵盐为代表的超细干粉灭火剂ABC干粉灭火剂是Z古老的灭火剂之一，是当前消防产品的主力军；灭火机理以化学灭火为主，物理灭火为辅，应用于全淹没固定式灭火系统，低温性能好，效果好。的技术在于超细粉体的制备，其优异的性能是:

Superfine dry powder fire extinguishing agent represented by ammonium phosphate ABC dry powder fire extinguishing agent is one of the ancient fire extinguishing agents and the main force of current fire-fighting products; The fire extinguishing mechanism is mainly chemical fire extinguishing, supplemented by physical fire extinguishing. It is applied to the total submerged fixed fire extinguishing system, with good low temperature performance and good effect. The advanced technology lies in the preparation of ultra-fine powder, and its excellent properties are:

1.它具有很好的灭火速度和效率，对一般固体物质的表面燃烧(阴燃)有很好的灭火效果。超细干粉晶体粉末与燃烧表面接触时，发生一系列化学反应，在固体表面高温作用下熔化，形成玻璃状覆盖层，将固体表面与周围空气隔开，从而使燃烧窒息。

1. It has good fire extinguishing speed and efficiency, and has good fire extinguishing effect on the surface combustion (smoldering) of general solid substances. When the ultra-fine dry powder crystal powder is in contact with the combustion surface, a series of chemical reactions occur, which melt under the action of high temperature on the solid surface to form a glassy covering layer, which separates the solid surface from the surrounding air, so as to suffocate the combustion.

2.超细干粉灭火剂具有零大气臭氧层消耗潜能(ODP)和零温室效应潜能(GWP)，对人体皮肤无刺激，对防护物无腐蚀，无害。灭火后残留物易于清理。

2. Superfine dry powder fire extinguishing agent has zero atmospheric ozone layer depletion potential (ODP) and zero greenhouse effect potential (GWP). It has no irritation to human skin, no corrosion to protective articles, non-toxic and harmless. The residue after fire extinguishing is easy to clean.

3.屏蔽冷却热辐射功能:超细干粉灭火时，浓云状粉末与火焰混合，分解吸热反应可吸收火焰部分热量。这些分解反应产生的一些惰性气体，如二氧化碳和水蒸气，可以稀释燃烧区的氧气浓度，从而减弱火灾的燃烧反应。

3. Shielding cooling heat radiation function: when extinguishing with ultra-fine dry powder, the dense cloud powder is mixed with the flame, and the decomposition endothermic reaction can absorb part of the heat of the flame. Some inert gases produced by these decomposition reactions, such as carbon dioxide and water vapor, can dilute the oxygen concentration in the combustion zone, so as to weaken the combustion reaction of fire.

4.灭火效率高:单位体积灭火效率是哈龙灭火剂的2-3倍，是普通ABC干粉灭火剂的6-10倍，是七氟丙烷灭火剂的10-12倍。

4. High fire extinguishing efficiency: the fire extinguishing efficiency per unit volume is 2-3 times that of halon fire extinguishing agent, 6-10 times that of ordinary ABC dry powder fire extinguishing agent and 10-12 times that of heptafluoropropane fire extinguishing agent.

超细干粉灭火剂不仅适用于相对封闭空间的全淹没，也适用于室外火灾危险场所的局部应用。特别是对于A类火灾和深层次火灾，在工厂、仓库、古建筑(尤其是寺庙)使用超细干粉灭火剂Z为有效。

Superfine dry powder fire extinguishing agent is not only suitable for the total submergence of relatively closed space, but also suitable for local application in outdoor fire dangerous places. Especially for class a fires and deep-seated fires, it is effective to use ultra-fine dry powder extinguishing agent Z in factories, warehouses and ancient buildings (especially temples).

建筑、仓库(特别是寺庙)无管网超细干粉自动灭火装置的设计与应用。

Design and application of ultra-fine dry powder automatic fire extinguishing device without pipe network in buildings and warehouses (especially temples).

超细干粉自动灭火装置的应用是一项非常成熟的技术。该装置采用氮气驱动，无声常压，可实现局部保护和类气全淹没保护。启动方式有电控、温控、超导启动，单个装置即可使用，多个装置可以联动形成一个无管网的灭火系统。

The application of ultra-fine dry powder automatic fire extinguishing device is a very mature technology. The device is driven by nitrogen, silent and normal pressure, and can realize local protection and gas like total flooding protection. The startup modes include electric control, temperature control and superconducting startup. A single device can be used, and multiple devices can be linked to form a fire extinguishing system without pipe network.
