在可控条件下测定塑料生物降解性的试验评价方法

Test Method for Determining the Biodegradability of Plastic Materials under Controlled Condition

本试验评价方法是在总结目前国内外试验评价方法优缺点的基础上，通过对各种影响塑料生物降解速度因素的研究与优化提出来的。对普通牛皮纸和改性ＰＶＡ／淀粉塑料样品的测试结果表明，本试验评价方法是行之有效的，并具备一系列优点。

It was on the basis of evaluating the advantages and disadvantages of commonly used test methods,and by optimizing the factors of affecting the rate of biodegradation that this test method was designed.The test results of kraft paper and a kind of modified PVA/starch alloy showed that this test method was feasible.
