Abstract
Description
Изобретение относится к средствам пожаротушения. The invention relates to fire extinguishing means.
Известны аэрозольные огнетушащие составы (АОС), получаемые путем сжигания твердотопливной композиции (ТТК) окислителя и восстановителя - горючего. В качестве горючего в ТТК используются органические смолы, а в качестве окислителя - нитрат калия и перхлорат калия. Основными компонентами АОС при этом являются карбонат и хлорид калия, диоксид углерода (патент RU N 2019214, кл. A 62 C 2/00, 1994). Known aerosol extinguishing compositions (AOS) obtained by burning a solid fuel composition (TTK) of an oxidizing agent and a reducing agent - fuel. Organic tar is used as a fuel in the TTK, and potassium nitrate and potassium perchlorate are used as an oxidizing agent. The main components of AOC are carbonate and potassium chloride, carbon dioxide (patent RU N 2019214, class A 62 C 2/00, 1994).
Наиболее близким к предложенному является состав ТТК, содержащий (в мас. %): идитол 10 - 45, перхлорат калия или нитрат калия 55 - 90 (заявка WO N 92/17244, кл. A 62 D 1/00, 1992). Closest to the proposed is the composition of the TTC containing (in wt.%): Iditol 10 - 45, potassium perchlorate or potassium nitrate 55 - 90 (application WO N 92/17244, class A 62 D 1/00, 1992).
К достоинствам этих составов относятся высокая огнетушащая способность, отсутствие экологической вредности и токсичности, простота и дешевизна применения и др. The advantages of these compounds include high fire extinguishing ability, the absence of environmental hazards and toxicity, simplicity and low cost of use, etc.
Наряду с достоинствами эти составы обладают и недостатками, основными из которых являются высокая температура АОС и наличие открытого форса пламени, а также агрессивное воздействие на некоторые материалы, препятствующие, например, использованию аэрозольного способа для защиты музеев, галерей и т. п. Агрессивное действие АОС на иконы, картины и т.п. связано с тем, что из карбоната калия образуется щелочь - гидроокись калия. Кроме того, известные составы не обеспечивают надежное тушение тлеющих материалов (пожаров подкласса А1). Along with the advantages, these compositions also have drawbacks, the main of which are the high temperature of the AOS and the presence of an open flame force, as well as the aggressive effect on some materials that impede, for example, the use of the aerosol method to protect museums, galleries, etc. The aggressive effect of AOS on icons, paintings, etc. due to the fact that an alkali is formed from potassium carbonate - potassium hydroxide. In addition, the known compositions do not provide reliable extinguishing of smoldering materials (fires of subclass A1).
Для устранения агрессивного воздействия известных составов предлагается использовать новый состав ТТК, состоящий из красного фосфора (горючее), нитрата калия (окислитель), фосфата калия в качестве разбавителя для регулирования скорости горения ТТК. Использование такого разбавителя обеспечивает также дополнительное количество соединений калия, осуществляющих активное ингибирование реакций, ответственных за развитие процесса горения. To eliminate the aggressive effects of the known compounds, it is proposed to use a new TTK composition, consisting of red phosphorus (fuel), potassium nitrate (oxidizing agent), potassium phosphate as a diluent to control the rate of combustion of the TTK. The use of such a diluent also provides an additional amount of potassium compounds that actively inhibit the reactions responsible for the development of the combustion process.
Предлагается следующая рецептура нового ТТК (в мас.%): фосфор красный (P) 20 - 25, нитрат калия (KNO3) 75 - 80, фосфат калия (K3PO4 или K2HPO4, или KH2PO4) 5 - 50 от суммарной массы ТТК, состоящего из фосфора и селитры.The following new TTK formulation is proposed (in wt.%): Red phosphorus (P) 20–25, potassium nitrate (KNO 3 ) 75–80, potassium phosphate (K 3 PO 4 or K 2 HPO 4 , or KH 2 PO 4 ) 5 - 50 of the total mass of TTK, consisting of phosphorus and nitrate.
Предлагаемый состав (без разбавителя - фосфата калия) имеет следующие характеристики: огнетушащая концентрация 24 г/м3, скорость горения 4 мм/с, температура горения 2200 K. Воздействия на музейные экспонаты не обнаружено. Важным преимуществом предлагаемого нового состава является также его способность тушить пожары подкласса А1. Это качество обусловлено тем, что среди компонентов АОС имеется фосфорный ангидрид P2O5, создающий пленку на поверхности горящего материала, препятствующую доступу кислорода в зону горения.The proposed composition (without diluent - potassium phosphate) has the following characteristics: fire extinguishing concentration of 24 g / m 3 , combustion rate of 4 mm / s, combustion temperature of 2200 K. No effect on museum exhibits was found. An important advantage of the proposed new composition is also its ability to extinguish fires of subclass A1. This quality is due to the fact that among the AOS components there is phosphoric anhydride P 2 O 5 , which creates a film on the surface of the burning material, which prevents the access of oxygen to the combustion zone.
Фосфат калия играет лишь вспомогательную роль и никакого агрессивного влияния на музейные ценности не оказывает. Potassium phosphate plays only an auxiliary role and does not have any aggressive effect on museum values.
Приготовление состава осуществляется простым механическим смешением компонентов с последующим умеренным прессованием вручную. The preparation of the composition is carried out by simple mechanical mixing of the components, followed by moderate pressing by hand.
