项目摘要
We investigated decomposition of composites containing asbestos by melting using laser irradiation. Many laser sources were compared and continuous and pulsed irradiation were tested, and we discovered that pulsed irradiation from a low-cost CO_2 laser can be used for processing. Various processing conditions were investigated with a small laser system with 50W output. We found a condition that allows a small laser system to process 5mm-thick asbestos, which is close to 6mm, the thickness of a slate. Observation by SEM of the processed region confirmed removal of asbestos.
我们研究了含石棉的复合材料的分解熔融使用激光照射。比较了多种激光光源,并进行了连续和脉冲辐照实验,发现低成本的CO_2激光器脉冲辐照可以用于加工。采用50W激光器对各种工艺条件进行了实验研究。我们发现了一个条件,允许一个小型激光系统处理5毫米厚的石棉,这是接近6毫米,石板的厚度。通过加工区域的SEM观察证实了石棉的去除。
