A firecracker fuse

Abstract

The invention relates to firecracker firing cable charge, which is characterized in that the firecracker firing cable charge consists of the following raw materials by mass percent: 15-40 percent of potassium perchlorate, 20-60 percent of nitrate barium, 1-10 percent of potassium hydrogen phthalate, 10-40 percent of hemp stalk charcoal or flue-cured tobacco stem charcoal, 2-10 percent of titanium powder and 1-5 percent of aluminum powder. A processing method of the firecracker firing cable charge comprises the following steps of: weighing the raw materials according to the mass percent and evenly mixing the raw materials; adding water into the evenly mixed raw materials and mixing to prepare paste; and penetrating a nitrated cotton thread through the prepared raw material paste to enable the cotton thread to be evenly coated with the firing cable charge, air-drying or drying and cutting the cotton thread into sections, packaging the cotton thread sections and storing the cotton thread sections indoors. A firecracker fuse-filling firing cable charge produced by adopting a wet process is simple and convenient to operate, the production efficiency is high, and process links such as starching, cable winding and air-drying are saved.

Description

Technical field [0001] The invention relates to a firecracker fuse. Background technique [0002] People in the field of firecracker production technology know that the current medicine for producing firecrackers and fuse is composed of potassium chlorate as the oxidant as the leading drug for the production of firecrackers. [0003] As everyone knows, firecrackers are made up of single-shot firecrackers of a certain specification by manual or mechanical knotting. The explosion of a single firecracker depends mainly on the fire transmission performance of the fuse inserted in the firecracker cartridge in a sealed and closed state, and whether it can ignite the effect of the firecracker and produce an explosion. Firecrackers have a high ignition rate and a high rate of firecrackers. Otherwise, there will be a lot of "dumb" and low rate of explosion. At present, domestic civilian firecrackers have not yet replaced the chlorate as the component of the firecrackers inserted fuse prod...

Problems solved by technology

Therefore, this kind of firecracker insertion lead wire with chlorate as the formula is too large in the semi-manual and semi-mechanized operation links, which not only affects the improvement of production efficiency, but also leaves a huge gap for the firecracker automatic assembly line. security risk
