【摘要】 研究了聚乙烯醇、塑化剂等主要原料及无机填料CaCO3的含量对降解材料性能的影响.结果表明:随着聚乙烯醇、塑化剂含量增加,材料的机械性能有较大提高,尤其是断裂伸长率变化显著;加入碳酸钙可以提高制品的刚度、尺寸稳定性等,但强度、断裂伸长率有所下降.更多还原

【Abstract】 The influence of content of the main raw material, such as PVA, plasticizer and inorganic filler CaCO₃ on the performance of the material which can be biodegradated is researched. The material’s mechanical behavior was greatly advanced with the increase of the content of PVA and plasticizer, especially the specific elongation at rupture; the addition of CaCO₃ increased the product’s rigidity and dimension stability, but reduced the intensity and specific elongation at rupture.更多还原
