Background
At present, in the preparation of firework powder, in order to enable fireworks to show a colorful visual effect when being set off, an oxidant mainly comprising perchlorate is often selected. However, when such an oxidizing agent is mixed with a combustible agent to prepare a pyrotechnic composition, a relatively dense smoke and CO are generated during ignition2Not only the ornamental effect is greatly reduced, but also the air quality is reduced and the environment is burdened due to serious air pollution. And various environmental problems caused by greenhouse effect are intensified year by year in recent years, and more extreme points are achievedWeather, abnormal climate, etc. have a close impact on our lives. Reduction of CO2The discharge is carried out, so that the climate change caused by the overhigh carbon discharge amount is reduced as soon as possible, and the survival pressure is relieved. On the premise of maintaining the ornamental value of fireworks, CO is trapped by using adsorbent2Reduction of CO emitted into the atmosphere from the discharge2The amount is currently the effective method. The calcium-based adsorbent mainly based on marble has the advantages of wide raw material source, low cost, large adsorption capacity and good application prospect.
In the 20 th century, 1.3 million square meters of marble had been produced in china. On average, in the marble cutting and polishing process, the produced marble powder is 20% of the volume of the original marble, causing serious resource waste and dust pollution. If the waste materials in the marble production process can be fully utilized, the powder and the leftover materials generated by cutting the marble are prepared into the adsorbent used as the firework filling material, and huge environmental protection value and considerable economic benefit can be realized. Aiming at the problems, the invention provides a firework filling material with a smoke adsorption effect prepared from marble waste, which solves the problems of air quality reduction and environmental pollution caused by powder generated after fireworks are set off and during marble cutting, and fully realizes the reutilization of the waste generated during marble production and cutting. The method can solve the environmental problem caused by overlarge waste amount, and can recycle resources, thereby solving the practical problem and having multiple practical application meanings.
