废旧聚苯乙烯高效利用技术研究进展

Research Progress of High Efficiency Utilization Technology of Waste Polystyrene

聚苯乙烯塑料具有传热系数低、质轻、机械性能良好、易着色、耐酸碱等众多特点,用途广泛,基于其化学稳定性好,难于降解和形成严重的"白色污染",其高效利用受到广泛关注。综述了废旧聚苯乙烯(WPS)塑料高值化利用技术的研究进展,使其变废为宝,在实现资源循环利用的同时解决环境污染问题。

Polystyrene plastic has many characteristics, such as low heat transfer coefficient, light weight, good mechanical properties, easy coloring, acid and alkali resistance, etc and widely used. Because of its good chemical stability, it is difficult to degrade and forms a serious "white pollution". The efficient utilization of waste polystyrene(WPS)has been widely concerned. In this paper, the research progress of high value utilization technology of WPS is reviewed, which is expected to turn waste into treasure, realize resource recycling and solve the problem of environmental pollution.
