Production method of firework leading yarn

Abstract

The invention discloses a production method of a firework leading yarn. The production method sequentially comprises the following steps: 1, adhering pyrotechnic slurry to a yarn to obtain a wet core;drying the wet core obtained in step 1 to obtain a dry core; and wrapping the dry core obtained in step 2 by using a paper tape to obtain a finished product of the leading yarn. Due to the adoption of the technical scheme, the wet core is wrapped and molded after being directly dried. The finished product of the leading yarn does not need to be dried. No overcladding is provided during drying, sothat both the drying efficiency and quality are greatly improved; and meanwhile, drying and molding are integrally completed without transition, so that the working efficiency is also greatly increased, the labor load is relieved, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to a production method of fireworks and firecracker lead wires. Background technique [0002] Firework fuses are used for the ignition and transmission of fireworks and are an important part of fireworks. Firework yarn lead is a kind of lead wire made based on wet method lead wire. Due to the production and use of powdery pyrotechnic powder, there is too much drug dust and environmental pollution, which not only poses a serious safety hazard, but is also easy to Occupational diseases such as silicosis are caused to workers. For this reason, a pyrotechnic drug wet treatment process has occurred. After taking the drug in proportion, the powdered drug is mixed evenly, and an appropriate amount of solvent (such as a moisture-proof agent for fireworks) is added and stirred evenly, so that the drug becomes a viscous fluid slurry state (called For wet medicine) for standby. [0003] The yarn is used to adhere the gunpowder slurry to t...

Problems solved by technology

[0006] The disadvantage of the existing technology is that the existing yarn leads are formed first and then dried. After the formed leads are reeled, they are transported to the drying place or drying equipment, uncoiled, dried or dried, and then rewound and stored for use. , the workload of transit transportation is heavy; and the drug core of the formed lead is wrapped by the outer cladding composed of paper tape or yarn, resulting in long drying cycle of the lead, high energy consumption, high production cost, and low drying quality; at the same time, the transit transportation of a large number of leads There is a serious safety hazard in concentrated drying
