前言为发展我国烟花炮竹工业,增加烟花花色品种,扩大稀土的应用领域,1983年以来,我们在南海红旗炮竹厂的大力协助下,经过多次的小型试验和工业试验,证明稀土铜镁合金在烟花中可以作可燃剂,穗花剂、发色剂。稀土金属燃点低,燃烧时放出大量的热。每摩尔稀土燃烧生成相应氧化物所放出的热比铝还要多。因此,稀土作为烟花材料可以提高烟花的燃烧温度。更重要的是稀
Foreword In order to develop the fireworks and firecrackers industry in our country, increase the variety of fireworks and flower varieties and expand the application fields of rare earths, since 1983, with the great help of the Red Flag Gun and Bamboo Factory in the South China Sea, after many small-scale experiments and industrial tests, Alloy fireworks can be used as combustible agent, Agronomy, hair color agent. Rare-earth metal ignition is low, emit a lot of heat burning. Each mole of rare earth oxides produces more heat than aluminum. Therefore, rare earth as a fireworks material can increase the fireworks combustion temperature. More importantly, it is thin
