火災特征:
Fire characteristics:
古建筑多為木結構，遇火后容易產生陰燃，是A類火災中難發生的火災。工廠、倉庫(尤其是寺廟)里的古建筑，大部分都鋪著木瓦，木瓦頂端，形狀各異。寺廟和道觀等相當數量的古建筑位于偏遠的山區和村莊。由于交通不利，年久失修，缺少香火，政府文物管理部門管不了，無人看管，或者只是無人看管，不使用。甚其中一些古建筑被列為和省級文物保護單位，具有很大的建筑藝術和文物保護價值。其中一些古建筑甚常年鎖著門，無人看管。只要發生火災，后果不堪設想。
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.
超細干粉滅火劑對工廠、倉庫、古建筑(主要是寺廟)火災的適用性。超細干粉滅火裝置適用性能
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
以磷酸銨鹽為代表的超細干粉滅火劑ABC干粉滅火劑是古老的滅火劑之一，是當前消防產品的主力軍；滅火機理以化學滅火為主，物理滅火為輔，應用于全淹沒固定式滅火系統，低溫性能好，效果好。的技術在于超細粉體的制備，其優異的性能是:
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.它具有很好的滅火速度和效率，對一般固體物質的表面燃燒(陰燃)有很好的滅火效果。超細干粉晶體粉末與燃燒表面接觸時，發生一系列化學反應，在固體表面高溫作用下熔化，形成玻璃狀覆蓋層，將固體表面與周圍空氣隔開，從而使燃燒窒息。
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.超細干粉滅火劑具有零大氣臭氧層消耗潛能(ODP)和零溫室效應潛能(GWP)，對人體皮膚無刺激，對防護物無腐蝕，無害。滅火后殘留物易于清理。
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.屏蔽冷卻熱輻射功能:超細干粉滅火時，濃云狀粉末與火焰混合，分解吸熱反應可吸收火焰部分熱量。這些分解反應產生的一些惰性氣體，如二氧化碳和水蒸氣，可以稀釋燃燒區的氧氣濃度，從而減弱火災的燃燒反應。
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.滅火效率高:單位體積滅火效率是哈龍滅火劑的2-3倍，是普通ABC干粉滅火劑的6-10倍，是七氟丙烷滅火劑的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.
超細干粉滅火劑不僅適用于相對封閉空間的全淹沒，也適用于室外火災危險場所的局部應用。特別是對于A類火災和深層次火災，在工廠、倉庫、古建筑(尤其是寺廟)使用超細干粉滅火劑為有效。
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、倉庫(特別是寺廟)無管網超細干粉自動滅火裝置的設計與應用。
Design and application of ultra-fine dry powder automatic fire extinguishing devices without pipeline network in buildings and warehouses (especially temples).
超細干粉自動滅火裝置的應用是一項非常成熟的技術。該裝置采用氮氣驅動，無聲常壓，可實現局部保護和類氣全淹沒保護。啟動方式有電控、溫控、超導啟動，單個裝置即可使用，多個裝置可以聯動形成一個無管網的滅火系統。
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.
