A paper on the advantages and disadvantages of setting off firecrackers

Fireworks is an immoral and sinful industry: it pollutes the environment, wastes strategic resources, intensifies bribery, controls hazards and threatens people's lives. In fact, it wastes resources, pollutes the environment and endangers personal safety. It's nothing more than sending 1, which won't be full, lest 1 1 scare others. The pollutants produced by fireworks and fireworks combustion are similar to those emitted by automobile exhaust and coal combustion. Firecrackers also forget it, that is, they produce nitrogen and sulfur compounds with zero harm; When the colorful luminescent substances of fireworks burn, they will produce more toxic substances. For example, firecrackers should emit particularly bright white light and silver light. In addition to adding aluminum and magnesium, rare earth element titanium should be added. To produce colored light, non-ferrous metals are essential, and heavy metals and rare earth metals have good flame color effects, such as manganese, chromium, nickel, vanadium, molybdenum, tungsten and cerium (the main flint materials of traditional lighters). Smokeless fireworks mainly use nitrocellulose, which has been around for more than 0/00 years. Hunan Province, Jiangxi Province and the Ministry of Science and Technology have invested more than 100 million yuan, and the low-pollution fireworks developed are not up to the level of R small enterprises. Compressed air cold strike (from 15,16th century) fireworks, time programmable preset software and integrated circuit delay electronic ignition fuze (from 1940) are engineering technologies that have been publicly used in this field abroad for more than ten years. The repost is as follows:/question/114520356.html? Si=4 Liangzi of Liuyang Fireworks Factory is soaked in water to irrigate crops. What harm will people do if they eat crops? Pyrotechnics are the core of finished fireworks. Its components include: (1) oxidant; (2) combustible materials; (3) substances that color the flame; (4) adhesive; (5) Special substances such as flute, chlorine-containing organic substances, preservatives, moisture-proof agents, etc. Name, barium nitrate, potassium nitrate, potassium perchlorate, strontium carbonate, copper oxide, bismuth oxide, cryolite, antimony sulfide, birch bark paint, phenolic resin, polyvinyl chloride resin, sulfur, red lead, aluminum slag, aluminum silver powder, carbon powder, strong powder, titanium powder, high-potassium flute, military nitrate, aluminum-magnesium alloy powder and other medicinal materials. The most poisonous is not sulfide, but dioxin, a strong carcinogen produced by the burning of organic matter! ! ! ! In addition, the non-ferrous metal vapor produced by the flame color agent, also known as the effect drug, also pollutes the environment and remains in the soil! ! ! All kinds of toxic substances are in it. I come from Liuyang. I know this very well. The chemical raw materials of fireworks factory are all toxic substances. Answer: Zeng Huanwen's family is rich and powerful. What about you? ! ! ! ! There are too many social problems. The output value of fireworks in China exceeds 50 billion yuan. To support a large number of production enterprises, what industry can be used to change birds? Fireworks and firecrackers management departments, safety supervision departments, public security departments, fire departments, hospitals, medicines, surgical instruments, funeral homes, etc. It is indispensable for this industry to rely on these to eat. If these people don't shoot, they will do more dangerous things. They want these enemies of level 0 to vent, vent, and release their hatred for @ @ 1 instead of 1 @. Therefore, existence is reasonable! ! ! ! ! ! ! !

Does anyone know the amount of gunpowder used to set off firecrackers in China every year? Converted into TNT equivalent. Let's do the math! The annual output value of fireworks in China exceeds 50 billion yuan, half of which is in China. According to the calculation in the industry, the gross weight of high-grade fireworks (such as high-altitude fireworks) is about one kilogram in 50 yuan (the ex-factory price is so low, the industry has high profits, many patterns and deep water), and the gross weight of ordinary firecrackers can be converted into TNT equivalent of 0.0 1 kg to 0.02 kg on average. The national fireworks industry consumes 200,000 tons of gunpowder and 300,000 tons of effective drugs every year. Therefore, it is estimated that the equivalent of TNT is in the order of 10 million kilograms to 1 million kilograms. Please refer to for details; Simple production method of blasting equipment Zhang Deyao Beijing: National Defense Industry Press 1965 published 2 15 pages, light green cover. Ask for fireworks composed of special symbols ~ urgent! Report to the leader: truthfully report as follows-there are several schemes to produce fireworks with patterns; The oldest is the gunpowder array fixed on the ground, which is ignited together or pre-programmed, and ignited at certain intervals so that children can understand it. There are also bundled formwork and scaffolding, and there are also cranes to lift the formwork to a height of more than 30 meters. Either there is a three-dimensional cavity made of paper in the projectile, which is arranged according to the pattern you need. This is a customized process according to customer's requirements. There are bonded and rolling powder balls (commonly known as bright beads in the industry) in the cavity, which explode after the fireworks are launched. Burning luminous powder balls can form simple patterns in space, and the price is 1000 to 3,000 yuan, and the manufacturing cost is less than that of 500 yuan. Because the effect is rubbish, the effect will be stable only if many projectiles with electronic delay fuzes are fired into the air at the same time to form a plane parallel array and a pattern is formed according to the pre-arranged ignition time of each point. Now they all learn from the practice of foreign countries ten years ago and adopt programmable electronic delay fuze. Because there are many imitation manufacturers, the original special chip has long been replaced by a general-purpose single chip microcomputer, and the fuse cost starts from 10 yuan. The firing tubes at fixed intervals on the ground, the direction of each firing tube should be tested, which is the dot matrix pattern of the fireworks in Beijing Olympic Games and Tiananmen Square on the 60th anniversary of New China. The standard price of this kind of barrel array and ground programming launch computer is more than one million yuan respectively. For ordinary customers, 20,000 yuan can open a rough system. The minimum cost of typing a word is 20 thousand, and the reserve price is also open. An integrated circuit controls timed fireworks from 100 yuan to 1000 yuan, and ten points is 1000 yuan, earning the franchise of producing fireworks, transporting fireworks, storing fireworks and launching fireworks. Big customers not only type a few words, but also provide supporting services.
