摘要
废旧塑料的回收包括 3个阶段 :收集、分选、加工或再生等步骤。只有清洁的废旧塑料才能生产高质量的产品 ,这需要有效的塑料分选方法。评述了光选、电选、风力分选、密度分选、浮选等废旧塑料分选技术 。
Waste plastics recycling has three phases of activity: collecting,separating and processing or regenerating.An effective separation of mixed waste plastics is necessary because only clean,homogeneous resins can produce recycled plastics products of high quality.Separation technologies including optical separation,electrostatic separation,air classifiers separation,density separation,and flotation separation are efficient methods.And froth flotation has been proved to be the most useful one.
