Abstract
This invention relates to drug powder for replacing black powder in spraying fireworks without producing smoke. The drug powder is composed of: charcoal powder 35-45%, potassium nitrate 25-35% and nitrified cotton powder 25-35%. The drug powder has such advantages as reduced smoking amount (by 40% compared with traditional black powder), efficient recycle of expired military powder, reduced cost (3200-3500 yen/ton compared with 4000-5000 yen/ton of black powder), and high safety.
Description
Technical field
The invention belongs to the technical field of fireworks medication powder, be specifically related to a kind of gunpowder for fireworks in ejecting flowers.
Background technology
At present, use black powder as medicinal powder in the fireworks industry usually.Black powder mainly is made up of wood charcoal powder, saltpetre, sulphur.During its burning, generate minuteness particle, form smog, cause dust pollution.
On the other hand, China is in war footing for a long time since the establishment of the nation, has laid in a large amount of propelling charge.Because standing storage, gun propellant stability descends, and loses military value, and has certain potential safety hazard.Past and propelling charge that scrap retired for these adopts the method for burning nearby always, the not only dangerous destruction funds that also need of this mode, and in the destruction process, also can bring serious environmental to pollute.Can utilize the characteristic of retired propelling charge, it be the problem of very worth research that the application by new and high technology is translated into useful civilian goods production.
Summary of the invention
The present invention forms smog when solving in the prior art fireworks industry black powder burning, and problem of environment pollution caused provides a kind of smoke-less gunpowder for fireworks in ejecting flowers of alternative black powder.
The present invention adopts following technical scheme to realize: gunpowder for fireworks in ejecting flowers, contain 35%～45% wood charcoal powder, 25%～35% saltpetre, 25%～35% nitro-cotton powder, and described raw material mixes and gets final product.
Gunpowder for fireworks in ejecting flowers of the present invention contains 37%～43% wood charcoal powder, 27%～33% saltpetre, 27%～33% nitro-cotton powder, and described raw material mixes and gets final product.
Gunpowder for fireworks in ejecting flowers of the present invention contains 40% wood charcoal powder, 30% saltpetre, 30% nitro-cotton powder, and described raw material mixes and gets final product.
The order number of nitro-cotton powder of the present invention is 120 orders～130 orders.
Nitro-cotton powder of the present invention is commonly called as single original washing powder or 128 powder, is to adopt retired single-base propellent directly broken and make, and mainly is applicable to fireworks and firecrackers production.Its performance index: nitrogen content: 12.4-14.2%; Outward appearance: yellow flour, do not have obviously visible impurity; Granularity: 60 orders, 80 orders, 100 orders, 120 orders, 130 orders etc.; 80 degree oven test: 〉=10min; Bursting point: 〉=178 ℃; Ash :≤0.4%; Moisture: 18-22%.
The present invention can also substitute the black powder in other class fireworks of fireworks industry.
Part experimental data of the present invention is summarized as follows table:
| Medicinal powder component and content | Experiment effect | The analysis of causes |
| 30% wood charcoal powder, 30% saltpetre, 40% 60 order nitro-cotton powder | Combustion speed is slow, and 2/3 medicinal powder is in paper shell internal combustion | Thicker and the wood charcoal powder of nitro-cotton powder, saltpetre mix inhomogeneous |
| 30% wood charcoal powder, 30% saltpetre, 40% 80 order nitro-cotton powder | Combustion speed is slow, and 1/3 medicinal powder is in paper shell internal combustion | The still thicker and wood charcoal powder of nitro-cotton powder, saltpetre mix inhomogeneous |
| 30% wood charcoal powder, 30% saltpetre, 40% 130 order nitro-cotton powder | The combustion speed ratio is more suitable, and 1/5 medicinal powder unburn just ejects | Spray speed is fast, but provides heat not enough |
| 35% wood charcoal powder, 35% saltpetre, 30% 60 order nitro-cotton powder | Combustion speed is slow, and 1/4 medicinal powder is in paper shell internal combustion | Thicker and the wood charcoal powder of nitro-cotton powder, saltpetre mix inhomogeneous |
| 35% wood charcoal powder, 35% saltpetre, 30% 80 order nitro-cotton powder | Combustion speed is slow, and 1/5 medicinal powder is in paper shell internal combustion | The still thicker and wood charcoal powder of nitro-cotton powder, saltpetre mix inhomogeneous |
| 35% wood charcoal powder, 35% saltpetre, 30% 130 order nitro-cotton powder | The combustion speed ratio is more suitable, and a spot of medicinal powder unburn just ejects | Spray speed is very fast, but provides heat not enough |
| 40% wood charcoal powder, 30% saltpetre, 30% 60 order nitro-cotton powder | Combustion speed is slower, and circuit fire phenomenon is arranged | Thicker and the wood charcoal powder of nitro-cotton powder, saltpetre mix inhomogeneous |
| 40% wood charcoal powder, 30% saltpetre, 30% 80 order nitro-cotton powder | Combustion speed is slow slightly | Nitro-cotton powder and wood charcoal powder, saltpetre mix inhomogeneous |
| 40% wood charcoal powder, 30% saltpetre, 30% 130 order nitro-cotton powder | Combustion speed is suitable, the medicinal powder unburn of trace | It is suitable to fill a prescription |
The present invention compares with prior art has following beneficial effect:
1, the amount of being fuming is little, and traditional relatively black powder reduces 40% the amount of being fuming, environmental protection more;
2, the retired military explosive of trans-utilization had both reduced the processing cost of retired military explosive, can turn waste into wealth again, reduced the production cost of fireworks, and the cost of original black powder is 4000-5000 unit/ton, and medicinal powder cost of the present invention is 3200-3500 unit/ton;
3, safety performance height, firework display effect are good.
