研究了废旧冰箱聚氨酯泡沫塑料（PUR）中CFC-11的总含量，测定了冰箱面板切割、板材剥离和破裂PUR泡沫塑料放置过程中CFC-11的释放量，结果表明：PUR泡沫塑料中CFC-11的含量为20.06%;板材切割和板材剥离过程中CFC-11的释放量分别为0.75%和2.32（0.5，1.0，4.0，8.0 mm）在常温下放置15 d，CFC-11的累积释放量占CFC-11总量的4.75%~ 6.50%，高于板材切割和板材剥离过程中的释放量。
The total quantity of trichloromonofluoromethane(CFC-11) contained in polyurethane(PUR) foam of waste refrigerator was studied,and the releasing quantity of CFC-11 in the process of refrigerator panel cutting,plate peel off and cracked PUR foam placement were determined.The results showed that the content of CFC-11 in PUR foam was 20.06%,and the CFC-11 releasing quantity in panel cutting and plate peel off process were 0.75% and 2.32% respectively.Kept the different diameters of cracked PUR foam(0.5,1.0,4.0,8.0 mm) at ambieut temperature for 15 d,the CFC-11 accumulative release amount account for 4.75%-6.50% of total CFC-11,the release amount was higher than that in panel cutting and plate peel off process.
