摘　　要：降解性能是生物降解塑料制品的关键性能指标之一,试样的尺寸差异会影响其生物降解率。本文以生物降解塑料袋为主要研究对象,通过人工裁剪、高速粉碎机等前处理手段将其制备成不同尺寸的试样,并在实验室条件下使用堆肥化降解性能检测装置,分析其对生物降解率的影响。结果表明:试样的尺寸对生物降解率有重要影响,合适的尺寸能有效提升生物降解速率,缩短检测周期,为优化生物降解过程提供重要参考。Degradation performance is one of the key performance indexes of biodegradable plastic products,and the difference of sample size will affect the biodegradation rate.This paper takes biodegradable plastic bags as the main research object,and prepares them into samples of different sizes by artificial cutting,high-speed shredder and other pre-treatment methods,and uses composting-degradation performance testing equipment under laboratory conditions to analyze its influence on the biodegradation rate.The results show that the size of the sample has an important effect on the biodegradation rate,and the appropriate size can effectively improve the biodegradation rate,shorten the detection cycle,and provide an important reference for optimizing the biodegradation process.
