Abstract

Abstract:

A recycling technology of waste polyurethane foam of refrigeration equipment was proposed based on mechanical and physical method,it was proved that polyurethane materials can degrade under right conditions by experiments duo to the mechanical and physical effects,and the range and variance analysis of orthogonal test were used to obtain the affection of speed,time,feeding material weight on degradation efficiency of polyurethane in the range of given processing parameters.According to the affection,the influencing factors can be arranged as follows:speed,time,feeding material weight,and the optimal processing parameters are determined as follows:speed is as 2400r/min,time is as 120min.

Key words: polyurethane foam, separate, regeneration, orthogonal test

摘要：

提出了基于机械物理法的废旧制冷设备聚氨酯泡沫再生工艺,通过试验证明了在适当的条件下,由于机械物理作用,聚氨酯物料会发生降解,并利用正交试验的极差和方差分析,得出了在所设定的工艺参数范围内转速v、时间t、进料量m对聚氨酯降解效果的影响,其主次顺序依次为:时间t、转速v、进料量m,最优再生工艺的转速为2400r/min,时间为120min。
