Problems solved by technology

Simultaneously, the fast fuse made by the prior art can only play the role of quickly igniting fireworks products, and the light and color produced during the combustion process cannot become an integral part of the fireworks discharge effect, and cannot bring beauty to the discharge process. visual effects, and sometimes destroys the discharge effect

Embodiment 1

[0012] Example 1: According to the ratio of parts by weight (the same below), take 35 parts of nitrocellulose, 28 parts of bismuth oxide, 18 parts of magnesium aluminum alloy, and 42 parts of titanium powder. The above components are screened and mixed according to the general method, and the humidity is adjusted with an adhesive to form a paste, and the lead wire can be machined according to the known lead-making process. The adhesive can be thinner, paint, dextrin, and low-molecular organic solvents such as ketones, alcohols, and ethers. The setting of the aluminum foil protective layer can be realized by adhesive rolling, such as rolling aluminum foil adhesive paper on the outer layer of the lead wire.

Embodiment 2

[0013] Example 2: The difference from Example 1 is that the composition and weight / number ratio of the pyrophoric agent are: 5 parts of nitrocellulose, 3 parts of bismuth oxide, 3 parts of magnesium aluminum alloy, and 3 parts of titanium powder.

Embodiment 3

[0014] Example 3: The difference from Example 1 is that the composition and weight-to-number ratio of the pyrophoric agent are: 15 parts of nitrocellulose, 18 parts of bismuth oxide, 8 parts of magnesium-aluminum alloy, and 15 parts of titanium powder.

Abstract

The invention discloses a smoke-free quick lead, which comprises an inner core coated with an ignition charge, and a coating layer, wherein the ignition charge comprises the following components in parts by weight: 5-80 parts of nitro-cotton, 3-30 parts of bismuth oxide or red lead, 3-40 parts of magnesium aluminum alloy and 3-50 parts of titanium powder; and the titanium powder is mainly used for raising temperature, accelerating combustion speed and producing metal sparks. A commercially available product comprises metal titanium or sponge titanium with the purity of between 80 percent and 98 percent. The size of a pattern is decided by the particle size (mesh size) of titanium. The smaller the particles are, the smaller the pattern is. The larger the particles are, the larger the pattern is. Due to the adoption of the technical scheme, a produced firework slight-smoke lead drug composition produces very little smog during combustion. Determination of light transmittance indicates that the smog produced by the drug composition is less than 20 percent that of an equivalent amount of the conventional drug. Meanwhile, a flame shape can be produced in the set-off process, so that an artistic effect is provided.

Description

technical field [0001] The invention relates to an ignition fuse for fireworks, in particular to a quick fuse. Background technique [0002] The traditional quick fuse includes an inner core wrapped with pyrophorant, which is made by covering a layer of kraft paper with special equipment. It is used to connect the ignition device of each fireworks product to play the role of rapid ignition or fire transmission. Existing quick fuses, especially the burning of the pyrotechnic drug in them, will produce relatively large smoke. Since the quick fuses are used in a large amount, the smoke generated by them and the smoke caused by product combustion will pollute the environment and affect the physical and mental health of the surrounding people. In order to improve the environmental protection performance of fireworks products, it is also a problem that must be solved to provide a smokeless quick fuse. Simultaneously, the fast fuse made by the prior art can only play the role of ...
