摘要
比较了采用环戊烷或CO2作为发泡剂的聚氨酯泡沫的性能指标,分析了2种聚氨酯保温管的热损失,以环戊烷为发泡剂的聚氨酯保温管性能较优。
The property indexes of polyurethane foam using cyclopentane or CO2 as foaming agent are compared, the heat loss of the two kinds of polyurethane insulating pipes is analyzed, and the polyurethane insulating pipe using cyclopentane as foaming agent has better property.
