A match is proposed containing a holder 3 and an incendiary head 2, mounted on the end of the holder 3, while the holder is made in the form of a metal rod, on the part of which a combustible material 4 is applied, ignited by the incendiary head 2 at its end. To increase the efficiency of the ignition action, the combustible material is a mixture of combustible materials with a higher calorific value than that of wood and burns without the formation of drops and sparks. To provide a light alarm with a burning substance, non-slag or low-slag pyrotechnic compositions are taken, which create a pronounced color flame and smoke when burning.

Description

The utility model relates to pyrotechnic aids and can be used to kindle fireplaces, stoves, bonfires ("fireplace" match), and also to signal in the dark, functionally being a mini-false lamp ("signal" match).

Long-burning matches are known, including a block of compressed sawdust and fibers impregnated with an emulsion of paraffin from a porous wood material, for example cardboard, with an incendiary mass applied to them for ignition. (Pat. RU No. 2027692, IPC C 06 F 5/00, publ. 1995).

Such matches are inconvenient for igniting large particles of combustible material of fireplaces, bonfires, and other foci. The technology of their production is complex, in the wind they go out.

A match is known consisting of a rod of combustible material, two incendiary heads located at opposite ends of the rod, a sleeve of non-combustible material mounted to move along the rod. (German Patent No. 3300800, class C 06 F 1/24, 1984). Such a match is notable for its complexity.

In A.S. SU No. 546597, class C 06 F 5/00, publ. 1977, a match is presented containing a housing, inside which there are incendiary heads in the form of balls, and a mechanism for moving the ball of the incendiary head to the outlet, which provides the replacement of one head with another.

A match is known containing a hollow rod-holder, a liner located in the cavity of the holder, and a flammable head located at the end of the holder and in contact with the liner (AS SU No. 179686, class C 06 F 5/00, publ.).

The above matches are not reliable enough, especially in outdoor conditions, are inconvenient for kindling fireplaces, are complex in design and have a limited area of use.

Recently, a “gas match” (TU 5551-004-00255208-99) and a “tourist” match (TU 5551-004-54940509-2003) have been developed in Russia. The characteristics of these matches are given in the table.

As a prototype, a match was selected according to GOST 1820-85 (Fig. 1), which is a wood straw 1, impregnated with combustible material (paraffin, etc.) and having an incendiary (match) head 2 from one end of the pyrotechnic composition based on the oxidizing agent - potassium perchlorate and potassium dichromate, combustible sulfur, organic glue and fillers (ground glass, zinc oxide, etc.).

Such a match is ignited by friction against a surface coated with a “grater” phosphorus mass.

The disadvantages of such matches include the need to use natural wood, a short burning period, limited functionality (used only for igniting flammable objects, flammable liquids, gas): unreliable in the field, in the wind, in difficult weather conditions, inconvenient for kindling fireplaces, cannot be applied to signal.

The problem to which the proposed utility model is aimed is to expand the functionality of the device - matches by increasing the reliability of the fire and ensuring sustainable burning for a long period of time outdoors, i.e. in difficult weather conditions, in the wind, etc., ensuring the ignition of large particles of combustible material, such as wood in a fireplace or stove (increasing the efficiency of the ignition action), as well as using it to provide light and smoke alarms in camp conditions.

A match is proposed containing a holder and an incendiary head fixed to the end of the holder, while the holder is made in the form of a metal rod, part of which is coated with combustible material, ignited by the incendiary head at its end.

To increase the efficiency of the ignition action, the combustible material is a mixture of combustible materials with a calorific value higher than that of wood and burns without the formation of drops and sparks.

To provide a light alarm with a burning substance, non-slag or low-slag pyrotechnic compositions are taken, which create a pronounced color flame and smoke when burning.

It is advisable to apply combustible material to 2/3 of the length of the metal rod.

Combustible material from the incendiary head can be separated by a nitrocellulose varnish film or other similar high-energy varnish coating.

To increase the rust resistance of metal rods and increase the moisture resistance, the surface of the match can be coated with a layer of hydrophobic substance, for example, organosilicon varnish, paraffin, ceresin, ozokerite, etc. The table shows the comparative characteristics of the proposed solutions PM “match” and analogues.

The proposed match design is presented in figure 2.

A match product consists of a metal rod 3, which has a length of ~ 180 mm ("fireplace" match) and ~ 85 mm ("signal" match). Other geometrical sizes are possible. A layer of combustible material 4 is deposited on ~ 2/3 of the length of the rod 3. An incendiary head 2 of a flammable composition is placed at the end of the combustible material 4. The varnish film 5 serves to separate the combustible material 4 from the incendiary head 2.

Combustible material 4 of the “fireplace” match is a mixture of combustible materials with a higher calorific value than that of wood and burning without smoke with high heat for> 1-2 minutes (for example, polyethylene, polypropylene, urotropine, etc. )

For the possibility of using flammable material for signaling purposes, pyrotechnic non-slag or low-slag compositions are used, which create a pronounced color flame and smoke (such as a “minisite”) when burning. Such matches (with a rod length of 85 mm) burn out for more than 20 seconds, are not blown by the wind and are quite suitable for making bonfires in camp conditions. have an extended flame torch of a higher temperature.

As the metal for the rod can be used waste metal production.

A match is lit during friction against the so-called "grater", which is a paper base coated with a layer of grater phosphorus-containing composition, similar to all so-called safe, "Swedish" matches (GOST 1820-85).
