Firework safety fuse and manufacturing method thereof

Abstract

The invention discloses a firework safety fuse and a manufacturing method thereof. The drug core of the firework safety fuse is composed of cotton yarn adhered with fuse medicine; The organic solvent is stirred evenly, so that the drug becomes a viscous fluid slurry state; and then the fluid slurry is evenly adhered to the drug-introduced cotton yarn as a lead-in drug core by improving the structure of the lead-in machine. Its advantages are: reducing multiple high-risk technological processes in the processing of fuse drugs, eliminating the disadvantages of drug dust spreading in the production site in the cotton yarn package, and qualitatively improving production safety; improving product quality and eliminating The phenomenon of broken medicine, less medicine, and medicine leakage is avoided; there is no dust pollution in production and use, and the production personnel are prevented from being injured by occupational diseases such as silicosis.

Description

technical field [0001] The invention relates to a fuse for fireworks and firecrackers, in particular to a safety fuse for fireworks and a manufacturing method thereof. Background technique [0002] Firework fuse is a pyrotechnic product used to ignite, spread fire, and control time. According to the material of the outer wrapping layer, it can be divided into yarn paper fuse, safety fuse and kraft paper quick fuse. There are big differences in the production methods of various fuses. In the present fireworks production, the use of safety fuse is more and more, and safety fuse is to take pyrotechnic powder as medicine core, makes wrapping thing with cotton thread, is woven into outer weaving layer, is coated with the fuse of moisture-proof material. It is characterized by good moisture-proof and mildew-proof performance, high tensile strength, firmness and toughness, can burn in water, and is difficult to ignite from the side of the fuse. [0003] The manufacture method of ...

AI Technical Summary

Problems solved by technology

[0014] Existing technological procedure is longer, and operation is complicated, and manual operation link is many, and potential safety hazard point is many, and safety accident occurs from time to time; drug core interruption), less drug (the diameter of the ignition wire drug core is less than the normal value), drug leakage (the drug core leaks from the outer cladding) and other phenomena; moreover, the production and use of the existing process has too much drug dust, causing great environmental pollution , which not only poses a serious safety hazard, but also easily causes occupational disease injuries such as silicosis to workers even in normal production
