Method of manufacture

 

(57) Abstract:

The invention relates to a method of manufacturing a composition for the energy and gas-generating devices. The method includes preparing and mixing a water-soluble polymeric binder and combustible substances and then molding the resulting mixture. As the combustible substance use repiratory metal powder, which is a powdered aluminum or magnesium, or an alloy of aluminum with magnesium. As the binder used solution of polyethylene oxide in dioxane or methyl alcohol. In preparation components repiratory metal powder is crushed when mixed with water-soluble polymeric binder to provide chemical activity in the reaction with water and prevent air oxidation. The invention improves the efficiency and safety of the manufacture and operation of composition.

The invention relates to a method of manufacturing gidrologiya compositions intended in particular for use in the energy and gas-generating devices, and for thermochemical processing of wells in order to increase their debit and CMOS components, which consists in grinding and drying; preparing a powder composition by mixing the components; granulating, drying and compaction [A. A. Shidlovskiy. Fundamentals of pyrotechnics. M: “Defence industry”, 1954, S. 14-15].

The disadvantage of this method is its fire and explosion hazards when preparing a powder composition.

The known method of manufacture consists in preparing and mixing the binder and combustible substances, followed by molding the mixture [Brief encyclopedic dictionary. “Energetic condensed systems” M.: “the Janus-K, 1999, S. 457-459].

The disadvantage of this method is the high explosive.

The closest in technical essence and the number of common features is a method of making the composition, taken as a prototype and consists in preparing, mixing the water-soluble polymeric binder and a pyrophoric metal-containing fuel, followed by molding the mixture. At the stage of preparing the metal-containing substances carry out his preliminary mixing with the water-soluble polymeric binder, preventing, telesomatic solution of polyethylene oxide in dioxane or methyl alcohol, and as pyrophoric metal-containing substances - ultrafine powdered aluminum, magnesium or aluminium alloy with magnesium [RF Patent for application No. 2000115019 from 15.6.2000/Method of manufacture/ Mazalov Y. A. 2000].

The essence of the claimed method is that for efficiency and safety in the manufacture of composition consists in preparing, mixing the water-soluble polymeric binder and metallic fuel and subsequent molding of the mixture, as the metal-containing fuel is used nevirapine metal-containing substance, preparation of metal-containing substances carry out his preliminary grinding in the process of mixing the water-soluble polymer binder to improve the chemical activity in the reaction with water and prevent oxidation of the metal with oxygen.

The task we address the proposed method is to increase the efficiency and safety of manufacture and operation.

The technical result from the use of the inventive method is to provide a high reaction activity of metal-containing fuel and an EOI product.

The above technical result is achieved due to the fact that in the method of manufacturing hydroregime composition, including the preparation and mixing of components in the form of a water-soluble polymeric binder and fuel and their subsequent molding, according to the invention as a metal-containing fuel use nairatmya metal-containing substances, and high chemical reactivity apirogennogo metal-containing fuel in the reaction with water is provided by preliminary grinding in the process of mixing the water-soluble polymer binder to improve the chemical activity in the reaction with water and prevent oxidation by air oxygen.

As a binder in the known compositions are water-insoluble substances, which excludes the interaction of the components with water. Therefore, in the known hydroregime compositions are introduced powdered oxidizing agents decomposition products which are necessary for ignition (activation) of particles of metal that provides a flow of secondary chemical reaction of metal with water [A. A. Shidlovskiy. Fundamentals of pyrotechnics, M.: the Defense industry, 1954, S. 47].

Isues powdered metals with increasing dispersion more actively interact with the oxygen in the air. Starting from a certain critical diameter, the conditions under which the heat release rate due to oxidation of the metal begins to exceed the rate of heat removal. Breakdown of thermal equilibrium inevitably leads to spontaneous combustion of the powder. Under normal conditions in air critical parameters of spontaneous combustion in the first place, will be determined by the size of the particles. For example, the critical size of aluminum, in which the powder to become pyrophoric, is 0,7-0,85 mm.

Powdered metal powders to avoid spontaneous combustion Passepartout slow oxidation at the stage of production of powders or capsulebuy water-insoluble polymer films (e.g. silicon). This ensures the safety of the production process of manufacture formulations, but leads to a significant reduction in energy performance and virtually eliminates direct interaction between the metal fuel gidrologiya compositions with the main oxidant - water [Brief encyclopedic dictionary. “Energetic condensed systems” M.: “the Janus-K, 1999, S. 183].

The use of water-soluble polymer films for encapsulation pyrophoric Mediline in the process of manufacture and its use [RF Patent for application No. 2000115019 from 15.6.2000/Method of manufacture/ Mazalov Y. A. 2000]. Thus, the use of pyrophoric ultrafine metal powders by pre-mixing with water-soluble polymeric binder provides manufacturing gidrologiya compositions, their safe use and effective application through direct interaction with water. At the same time, the cost ultrafine metal-containing pyrophoric powders [Mazalov, Y. A., Meleshko C. Y., Pavlovets, J. Modeling and framework for the process of combustion of heterogeneous condensed systems. - M.: VA strategic missile forces. Peter The Great, 2001. 281 S.], get energy-consuming and unproductive ways (electrical explosion, plasma reconcretion and others), in 100 or more times higher than the cost of repiratory fine powders produced on an industrial scale. In addition, pyrophoric powders prior to their encapsulation of water-soluble film are dangerous ignition source and require special storage conditions.

In the proposed method, high chemical activity in the reaction with water (at the level of ultrafine powders) is provided for repiratory metal-containing substances by grinding in the medium of water-soluble polymeric binder is eperformax powders, reduced particle size and replace the protective oxide film on water-soluble. This provides the possibility of manufacturing high-performance gidrologiya compositions based repiratory powders produced on an industrial scale.

From the foregoing it is seen that there are technical solutions to achieve the mentioned technical result, while in the claimed method provides direct interaction with water repiratory metal particles by pre-grinding in the medium of water-soluble polymeric binder. This gives you the opportunity to be excluded from the expensive and explosive ultrafine metallic powders.

The applicant is not found technical solutions containing the operation to ensure a high chemical activity in the reaction with water and to prevent the air oxidation apirogennogo metallic fuel for the preparation of components by grinding and mixing with water-soluble polymeric binder, is not found use as components for the preparation of hydroregime pyrotechnic composition but the compliance of the way the criteria of the invention of “novelty” and “inventive step”.

In addition, for the preparation of components repiratory metal powder is crushed when mixed with water-soluble polymeric binder (binder content in the mixture is from 10 to 50%) to provide chemical activity in the reaction with water and prevent oxidation by air oxygen.
