SU624910A1 - Incendiary mass - Google Patents

Description

The invention relates to pyrotechnic compositions and can be used in the manufacture of matches.

Known pyrotechnic incendiary matches based on potassium chlorate, sulfur, animal glue, capi dichromate, pyrolusite, and various fillers i.

The disadvantage of these compositions is their high sensitivity to impact and friction.

The closest to the proposed composition is the incendiary mass, which, unlike other known compositions, additionally contains a gum sitter as an adhesive. Sulfur and glue are also contained in this mass as the main combustible substances, due to which it is also very sensitive to impact and friction and has a low ignition temperature (20 ° -210 ° C),

Match heads made with the use of such a mass often flames during production and transportation, which causes material damage from product losses and semi-finished products, resulting in damage to the equipment and burns of workers.

The purpose of the invention is to reduce the sensitivity to impact and friction.

This is achieved by the fact that the mass instead of sulfur contains pyrite (iron pyrites) in the following ratio of components, wt.%:

Potassium chlorate 53-54

Potassium dichromate 1.4-1.5

Pyrite (iron pyrites) 6.0-8.0 White zinc, O-8, O

Minium irony6, O-7.0

Pyrolusit1,2-1,5

Animal glue10-12

Gummitragant 0.2-0.3.

The mass is made and applied to matches according to the technology adopted in the match industry and on the equipment available. The proposed incendiary mass has a sensitivity to impact 1, O kgm (with a known composition of 0.22–0.25 kgm), the seam is sensitive to the terenro test, and the flame of the proposed mass is composed of 26O- .. Matches made using the proposed mass meet the requirements m GOST 1820-69 Matches. The load has been used with a positive effect on the Balabanovsky experimental plant and the Cherepovets match factories, P {I change the proposed igniter mass during production; allow the matches to increase the safety of production and cause loss associated with the ignition of matches in the process during the process of matches in the course of matches during the production process. The invention Incendiary mass for the manufacture of heads of matches, including potassium chlorate, potassium dichromate, zinc white. iron oxide, pyrolusite, zinc glue, gummitragant, ground glass and inorganic fuel, in order to reduce the sensitivity to impact and friction, it contains pyrite in the form of inorganic fuel, with the following component ratio , wt.%: Potassium chlorate 53-54 Potassium dichromate 1.4-1.5 Cyrite (iron pyrites) 6.0-8.0 Zinc white 6.0-8.0 Minium iron 6.0-7.0 Pyrolusite 1.2-1.5 Animal glue 10-12 Gummitragant 0.2-0.3 Ground glass Else.
