Firework electric igniter gunpowder

Abstract

The invention discloses an electric ignition cable switch gunpowder for fireworks, which consists of potassium perchlorate, lead nitrate and acid potassium sulfate which are mixed together; the weight ratio spans of each component are: 45 to 65 percent of the potassium perchlorate, 15 to 35 percent of the lead nitrate and 10 to 30 percent of the acid potassium sulfate; the electric ignition cable switch gunpowder for fireworks manufactured by adopting the technical scheme spurns to use dangerous goods and greatly improves the safety factors of the product; besides, the ignition property of the product is better than the original product; the ignition rate is 100 percent; the guarantee period is prolonged by more than 3 years; the invention is suitable for the manufacture demands of various electric ignition cable switch gunpowder for fireworks and better realizes the goal of the invention.

Description

technical field [0001] The invention relates to a pyrotechnic drug composition, in particular to an electric ignition head drug composition. Background technique [0002] The traditional ignition method of fireworks products is lead wire ignition, and now the electric ignition head ignition method has also been widely used. The two wires of the electric fire head are short-circuited with tungsten wires, etc., and the short-circuit point is coated with medicine. The existing electric ignition head Drugs mostly use a mixture of potassium chlorate, sulfur and antimony sulfide, which is extremely unsafe. First, the mixed medicament is extremely sensitive to mechanical action. The second is that the chemical properties of the mixture of potassium chlorate, sulfur and sulfide are extremely unstable. Potassium chlorate can be decomposed by strong acid, and sulfur can generate sulfur trioxide in a humid environment. Sulfur trioxide reacts with water to generate sulfuric acid. Sulf...

Problems solved by technology

Acute poisoning manifests as irritation to the respiratory tract, digestive tract and skin, and is likely to cause harm to the staff

Furthermore, the corrosiveness of the mixture tends to rust the wires, making the shelf life of the product shorter, and the product quality cannot be guaranteed for more than one year.
