摘要
利用热空气法生产聚苯乙烯泡沫塑料,探讨了预发泡和模压过程中的主要参数。在预发泡过程中,主要控制预发泡温度和时间,避免进入塌陷区;在模压过程中,主要控制模压时间、温度。实验证明,预发泡适宜工艺参数为:温度105℃,时间20分钟;模压适宜参数为:温度110℃,时间30～50分钟。
Discussed are the main parameters of time and temperature during prefoaming and molding in producing expanded polystyrene(EPS) plastics using heat air method.During the prefoaming process,prefoaming temperature and time are controlled well in order to avoid collapsing for the expanded particles,and during the molding process,the main parameters to control are molding time and temperature.The results show that suitable temperature and time are 105℃ and 20min respectively during prefoaming,and 100℃ and 30min～50min respectively during molding.
