EPS发泡倍率及保存期研究

STUDY ON FOAMIGING TIMES AND STORAGE PERIOD OF EXPANDABLE POLYSTYRENE

采用在 EPS 颗粒表面涂膜的方法延长其存放期,提高发泡倍率。实验表明:所用涂膜剂能使 EPS 的保存期延长一倍以上,且投资少、见效快,易于实现工业化生产。

The method of coating the particles on the surface of expandable polystyrene is developed to prolong the storage period and increase the foaming times.The experiments show that the storage period is twice uncoated one and this method has the advantages of lower investment,faster benefit and easier commerciallization.
