Abstract
The invention relates to a save firecracker that is made up by safe firecracker explosive and high firing temperature cable. The explosive is made up from potassium perchlorate, sulfur, aluminum powder, aluminum-magnesium alloy and carbon. The firing cable is made up from potassium perchlorate, potassium chlorate and carbon. The sound of the firecracker is better than the traditional firecracker and solves the save problem of impacting. The firing temperature is of the cable is increased and the usage of the explosive is decreased. It has the advantages of stable capability, loud exploding sound, strong radiation light and low cost.
Description
Technical field
The present invention relates to a kind of safety firecracker, particularly a kind of potassium perchlorate safety firecracker blasting powders and combustion temperatures firecrackers firing line medicine that contains aluminium-magnesium alloy powder.
Background technology
In the prior art, because Potcrate poor stability, fusing point is low, be after thermopositive reaction and organism, sulphur, most sulfide or other combustiblesubstances mix during decomposes, be heated, rub or clash into burning or blast all may take place, had a strong impact on the firecrackers productions, deposit, the safety in the transportation, use.Potassium perchlorate need absorb advantages such as heat when having stable performance, fusing point height, nonhygroscopic, decomposes, replace Potcrate with potassium perchlorate, can greatly reduce the susceptibility of firecrackers, improves safety performance.But, adopt traditional potassium perchlorate to replace the Potcrate alternative, production cost is than increasing more than 20% with Potcrate, and cost of goods sold is than increasing more than 15% with Potcrate.So, forbid all, to implement as yet with Potcrate preparation fireworks and firecrackers so far because of reducing cost from October, 2002 State Council's dispatch.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of low cost, high-quality safety firecracker are provided.
Core technology of the present invention: be that blasting powders adopts potassium perchlorate and aluminium-magnesium alloy powder, the firing line medicine adopts potassium perchlorate, and its particular content is as follows:
A kind of safety firecracker comprises safety firecracker blasting powders and firecrackers firing line medicine two portions:
The safety firecracker blasting powders is to be made by potassium perchlorate, sulphur, aluminium powder, aluminium-magnesium alloy powder and five kinds of raw materials of charcoal, and the weight proportion of its component is as follows:
Potassium perchlorate: 40～60% aluminium-magnesium alloy powders: 1～20%
Aluminium powder: 10～30% sulphur: 10～30%
Charcoal: 1～10%.
The firing line medicine is a combustion temperatures firecrackers firing line medicine, and it is to be formed by potassium perchlorate, Potcrate and three kinds of material combination of charcoal, and the weight proportion of its component is as follows:
Potassium perchlorate: Potcrate 10%～47%: 22～56%, charcoal: 14～34
Safety firecracker of the present invention reaches the minimizing content of dispersion, and safety reduces cost again again, and rate of explosion and sound value are better than the Potcrate firecrackers.The present invention is mixed in proportion these five kinds of materials and promptly can be made into the firecrackers blasting powders, has solved that the Potcrate firecrackers are deposited, the unsafe problems in the transportation, use, has solved the expensive problem of potassium perchlorate, has realized the low cost of safety firecracker.
Because the decomposition temperature of potassium perchlorate is higher, and absorb heat when decomposing, lower than Potcrate to the susceptibility of machinery so its chemical property is more stable than Potcrate, depositing does not separately have blast performance.Potassium perchlorate is made the oxygenant of fireworks and firecracker gunpowder, greatly reduces the susceptibility of fireworks and firecrackers, has improved security.Aluminium powder is a light metal, can improve temperature of explosion and brisance, and sulphur is to make reductive agent and combustiblematerials, and wood charcoal powder is the low ignition point combustiblematerials, impels the firecrackers blasting powders to be easy to igniting.
In component, adopt aluminium-magnesium alloy powder to make combustiblematerials, because 463 ℃ of the fusing points of aluminium-magnesium alloy powder, than 660.1 ℃ of aluminium powder fusing point near low 200 ℃, reduced the ignition temperature of firecrackers blast medicine, quickened the potassium perchlorate decomposition, improve the rate of starting to exchange fire and the sound value of firecrackers blast medicine, thereby significantly reduced content of dispersion.
Safety firecracker of the present invention adopts the firing line of combustion temperatures: promptly add potassium perchlorate in traditional firing line medicine, the temperature of combustion of original firing line medicine has been improved more than 400 ℃, improved the rate of starting to exchange fire of firecrackers blast medicine greatly, reduce the susceptibility of firing line, improved safety control.
The rate of explosion of safety firecrackers and sound value are better than traditional Potcrate firecrackers, do not use Potcrate to make oxygenant, have solved the high and dangerous big problem of bump, friction mechanism sensitivity of firecrackers blast medicine.Use aluminium-magnesium alloy powder to reduce the ignition temperature of firecrackers blast medicine, fundamentally improved the sound value and the explosion sound rate of traditional potassium perchlorate firecrackers as combustiblematerials.Use potassium perchlorate to make the medicine material of firing line, improved the temperature of combustion of firing line, solved the start to exchange fire problem of rate difficulty of potassium perchlorate firecrackers, significantly reduced content of dispersion.Advantage such as have that safety coefficient height, stable performance, explosion sound rate height, sound are clear and melodious, radiation light intensity, production cost are low is not use oxymuriate to make the best scientific and reasonable method of firecrackers blast medicine.
Safety firecracker of the present invention, the firecrackers that sound value and explosion sound rate are made than Potcrate are better, production cost of the present invention is only than increasing below 1% with Potcrate, cost of goods sold is only than increasing below 0.5% with Potcrate, having very high promotional value, is the once great revolution of fireworks and firecrackers technology on the beginning.
The safety firecrackers are through economizing firework measuring station complete detection, and from the safety performance of blast medicine, every indexs such as the explosion sound rate that product is seted off, sound level all are better than national GB10631-04 fireworks and firecrackers inspecting standard; Blasting fuse of high-safety firecracker meets national GB19595-04 fireworks and firecrackers firing line inspecting standard fully.
