废旧手机电路板非金属回收及在塑料中的再利用进展

Progress on Recovery and Reuse in Plastic of Nonmetal in Waste Mobile Phone Circuit Boards

首先分析了废旧手机电路板非金属材料的存在形式和所含元素,然后综述了热解法、化学法和物理法等废旧手机电路板非金属材料的回收技术进展,分析了各种方法的工艺特点,最后重点介绍了废旧手机电路板中的非金属材料作为增强体应用于聚丙烯、聚氯乙烯、聚乙烯、尼龙等热塑性塑料和环氧树脂、不饱和聚酯等热固性塑料的研究现状。

The existing forms and elements of non-metallic materials in used mobile phone circuit boards were analyzed firstly,and then the reuse technology progress of non-metallic materials in used mobile phone circuit boards,such as pyrolysis,chemical method and physical method,was mainly reviewed,and the process characteristics of various methods were analyzed.At last,the research status of non-metallic materials used as reinforced system for applying to thermoplastics such as polypropylene,polyvinyl chloride,polyethylene,nylon and thermosetting plastics such as epoxy resin and unsaturated polyester were emphatically introduced.
