环保型绿色火焰剂的研究

为了消除传统绿色火焰剂燃烧产生的钡盐污染和减少燃烧产生的可吸人颗粒物，通过选用氧化铜作染焰剂和氧化剂，并利用两种有机物作为可燃物获得了一种环保型的绿色火焰剂，氧化铜、可燃物A和可燃物B质量比为5：1．8：2。在同样条件下，新的绿色火焰剂的色纯度比传统药剂高17％，透过率高50％，而产生的二氧化氮、一氧化碳和可吸入颗粒物(PM10)分别是传统药剂的14％，50％和2％。结果表明，新的绿色火焰剂有较好的环保性能。

Study on Environmental Friendly Composition for Green Flare

In order to eliminate pollution caused by the barium oxide and decrease the inhalable particu-lates, a new green flare composition was obtained by using copper oxide as oxidant and color substance, two kinds of organisms A,B as combustible. The proportion of ingredients CuO,A and B is5: 1. 8: 2 by weight. The color purity and the permeation percent are respectively higher 17% and 50% than that of traditional green flare composition under the same conditions, but the amounts of nitrogen dioxide and carbon monoxide and inhalable particulates decreased by 14% ,50% and 2%. And the impacts of the content of copper oxide and two combustibles on the color purity and the smoke are studied. Results show that the pollution caused by barium salt can be eliminated using copper oxide as color substance; inhalable particulates can be decreased using organic substance as combustible.
