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

Embodiment Construction

[0039] see figure 2 , the firework safety fuse includes a wrapped sleeve 31 formed by weaving cotton yarn, the sleeve 31 is provided with a waterproof layer, and the sleeve 31 is wrapped with a drug core 30 composed of cotton yarn adhered with fuse medicine .

[0040] The preferred specific manufacturing method of the safety fuse is composed of the following steps in sequence:

[0041] Step 1, fuse drug preparation:

[0042] 1), get rid of the impurities in the medicine and take the medicine according to the following proportioning ratio: 25kg of potassium perchlorate; 7kg of fireworks whistle agent (potassium hydrogen terephthalate); 6kg of charcoal powder (Chinese fir charcoal powder);

[0043] 2), the above-mentioned powdery medicine is repeatedly sieved and mixed evenly;

[0044] 3), add 15kg of alcohol to the above-mentioned medicine and stir evenly, make the medicine into a viscous fluid slurry state, put it into storage for standby;

[0045] As common fireworks raw...

Abstract

The invention discloses a fireworks safety firing cable and a manufacturing method thereof. The fireworks safety firing cable comprises an ignition-composition core and cotton yarn attached with firing cable compositions; and the manufacturing method is mainly characterized by comprising the following steps: adding an appropriate amount of organic solvents into the prior firing cable compositions, and evenly stirring to enable the compositions to be in a thick fluid flurry state; and evenly attaching the fluid slurry onto priming cotton yarn as a firing cable composition core by improving the structure of a priming machine. The invention has the advantages that a plurality of process flows with higher hazards are reduced in the processing process of firing cable compositions, the defect that composition powder is interspersed in production places is avoided in the cotton yarn wrapping process, and the production security is improved qualitatively; the quality of the product is improved, and the phenomena of composition interruption, shortage and leakage are prevented from generating; no dust pollution is generated in production and application, and production personnel are avoided from being injured by occupational diseases, such as silicosis, and the like.

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 ...
