火灾特征:
Fire characteristics:
古建筑多为木结构，遇火后容易产生阴燃，是A类火灾中难发生的火灾。工厂、仓库(尤其是寺庙)里的古建筑，大部分都铺着木瓦，木瓦顶端，形状各异。寺庙和道观等相当数量的古建筑位于偏远的山区和村庄。由于交通不利，年久失修，缺少香火，政府文物管理部门管不了，无人看管，或者只是无人看管，不使用。甚其中一些古建筑被列为和省级文物保护单位，具有很大的建筑艺术和文物保护价值。其中一些古建筑甚常年锁着门，无人看管。只要发生火灾，后果不堪设想。
Most ancient buildings are made of wooden structures, which are prone to smoldering when exposed to fire, making them a rare occurrence in Class A fires. 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, prolonged disrepair, and lack of incense, the government's cultural relics management department is unable to manage it, leaving it unattended or simply not in use. Even some of these ancient buildings are listed as national and provincial-level cultural relics protection units, with great value in architectural art and cultural relics protection. Some of these ancient buildings even have locked doors all year round and are left unattended. As long as a fire occurs, 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 ultrafine dry powder fire extinguishing agents for fires in factories, warehouses, and ancient buildings (mainly temples). Applicable performance of ultrafine dry powder fire extinguishing equipment
以磷酸铵盐为代表的超细干粉灭火剂ABC干粉灭火剂是古老的灭火剂之一，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:
The ultra-fine dry powder fire extinguishing agent ABC, represented by ammonium phosphate, is one of the ancient fire extinguishing agents and the main force of current fire protection products; The fire extinguishing mechanism is mainly based on chemical fire extinguishing, supplemented by physical fire extinguishing. It is applied to fully submerged fixed fire extinguishing systems with good low-temperature performance and effectiveness. The advanced technology lies in the preparation of ultrafine powders, whose excellent performance is:
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 excellent fire extinguishing speed and efficiency, and has a good fire extinguishing effect on the surface combustion (smoldering) of general solid substances. When ultrafine dry powder crystals come into contact with the combustion surface, a series of chemical reactions occur, which melt under the high-temperature action of the solid surface, forming a glassy covering layer that separates the solid surface from the surrounding air, thereby suffocating 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. Ultra fine dry powder fire extinguishing agents have zero ozone depletion potential (ODP) and zero greenhouse effect potential (GWP), are non irritating to human skin, non corrosive to protective materials, and are non-toxic and harmless. The residue after 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 ultrafine dry powder is used for fire extinguishing, the concentrated cloud like powder is mixed with the flame, and the decomposition endothermic reaction can absorb some heat from the flame. The inert gases generated by these decomposition reactions, such as carbon dioxide and water vapor, can dilute the oxygen concentration in the combustion zone, thereby weakening the combustion reaction in a 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为有效。
Ultra fine dry powder fire extinguishing agents are not only suitable for total flooding in relatively enclosed spaces, but also for local applications in outdoor fire hazard areas. Especially for Class A fires and deep level fires, the use of ultrafine dry powder fire extinguishing agents is effective 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 devices without pipeline 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 ultrafine dry powder automatic fire extinguishing devices is a very mature technology. This device is driven by nitrogen gas, silent and atmospheric pressure, and can achieve local protection and gas like total flooding protection. The starting methods include electric control, temperature control, and superconducting starting. A single device can be used, and multiple devices can be linked to form a non pipe network fire extinguishing system.
