用SPEX冷冻研磨机研究已用过的塑料废弃物的加工和性能

Abstract This research is an effort to produce a useful polymer from a post-consumer mixed polymer waste stream consisting primarily of polypropylene and polyethylene. Mixed waste flakes were milled to a fine powder by cryogenic impact mil领, and then injection molded into tensile test samples. The effect of incorporating nanoclay before mil领 was investigated. Despite the presence of porosity in the milled powder samples, the tensile properties were found to be higher than those of the unmilled polymer. Differential scanning calorimetry thermal analysis suggests the possibility of the formation of alloy between the immiscible polymers. q 2005 Elsevier Ltd. All rights reserved.
