古建筑多為木結(jié)構(gòu),，遇火后容易產(chǎn)生陰燃,，是A類火災中Z難發(fā)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(shù)量的古建筑位于偏遠的山區(qū)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(shù)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(fā)生火災,，后果不堪設想。
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 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
以磷酸銨鹽為代表的超細干粉滅火劑ABC干粉滅火劑是Z古老的滅火劑之一,，是當前消防產(chǎn)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(tǒng),，低溫性能好，效果好,。的技術(shù)在于超細粉體的制備，其優(yōu)異的性能是:
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.它具有很好的滅火速度和效率,，對一般固體物質(zhì)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(fā)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 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. 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(chǎn)生的一些惰性氣體,，如二氧化碳和水蒸氣，可以稀釋燃燒區(qū)的氧氣濃度,，從而減弱火災的燃燒反應,。
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.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Z為有效,。
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,、倉庫(特別是寺廟)無管網(wǎng)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 device without pipe 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(shù),。該裝置采用氮氣驅(qū)動,，無聲常壓，可實現(xiàn)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(lián)動形成一個無管網(wǎng)的滅火系統(tǒng)。
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.
