摘　　要：研究了纸质快餐具在100℃、140℃和160℃不同温度处理过程中,试样的质量、白度、聚合度以及抗张强度的变化情况。实验表明:纸质餐具热降解明显,评价降解程度的各参数都发生了较大的变化。同时发现抗水抗油助剂在高温下对纸质餐具的降解影响不大,而在较低温度下对降解有一定的影响。The pulp mould fast food container was treated at100℃,140℃and160℃respectively and the change of the weight ,brightness of the sample,degree of polymerization,tensile strength and length of rupture was tested during the course of treatment.The results show that the thermal degradation of pulp mould container is obvious and the parameters evaluating the degradation extent change significantly.The effect of waterproof and oilproof agents on the degradation of container is slight under high temperature,but these agents affect the degradation in a certain degree under low temperature.
