摘要
通过国内几家单位所开发的光-生物降解发泡聚苯乙烯餐盒使用性能和降解性能的实验研究,初步提出应从理化指标、毒性指标及样品经氙灯光源加速老化试验、自然气候暴露试验和野外降解试验后红外光谱分析、样品厚度变化及分子量变化情况的测试等方面对新型餐盒进行评价,为该类产品的研制、开发及应用提供了依据。
Based on the service performance and degradability experiments of light-and bio-degradable foam PS snack containers developed by domestic unions, The evaluation for the snack containers should be replied upon the physical and chemical indexes,toxicity indexes, the 1R analysis of the samples after xenon are weathering out-doors exposure and degradation tests in field, and the measure ments of the changes of sample thickness and molecular weight. It can provide the scientific basis for research, development and application of this product.
