More Information
Summary:The invention discloses a method for detecting the content of a foaming agent in expandable polystyrene resin, which comprises the following steps of: obtaining a thermogravimetric curve of an expandable polystyrene resin sample by using a thermogravimetric method, and processing the thermogravimetric curve by using a centerline method to obtain the content of the foaming agent in the expandable polystyrene resin. The method has the beneficial effects that the use of harmful chemicals is avoided, and the test process is safe and environment-friendly. 本发明公开了一种可发性聚苯乙烯树脂中发泡剂含量的检测方法，首先使用热重法得到可发性聚苯乙烯树脂样品的热重曲线，再使用中线法对热重曲线进行处理，得到可发性聚苯乙烯树脂中发泡剂的含量。本发明的有益效果：杜绝有害化学药品的使用、使试验过程安全环保。
