摘要
自行设计并制作聚苯乙烯发泡设备,该设备是预发EPS珠粒的关键设备,实验首先通过对可发性聚苯乙烯颗粒进行预发泡,验证了本文自制发泡设备功能可行性,可根据不同的需求,预发密度可变的珠粒。与此同时,对EPS材料进行预发泡研究,确定最佳的预发泡工艺参数,并且获得比较满意的密度。实验结果表明：发泡级粒径在1.00～1.60mm之间,预发泡时间为30、50、70、90、110 s;其珠粒预发密度为35.693 2、20.383 6、18.270 0、17.276 0 g/L。阻燃级粒径在0.6～0.9 mm之间,预发泡时间为1、1.5、2、2.5、3 min;其珠粒密度为26.4、25.72、25.2、24.64、23 g/L。
To design and manufacture of polystyrene foaming machine, this is the key equipment of the advance EPS beads. The functionality feasibility of the self-produced foaming machine was verified by pre-foaming to polystyrene particles. According to the different needs, pre-foaming variable density beads. At the same time, the pre-foaming study to EPS material was conducted, the optimal pre-foaming process parameters and satisfactory density were obtained. The experimental results show that the foam level particle size is 1.00～1.60 mm, the pre-foaming time is 30, 50, 70, 90, 110 s,and the bead density is 35.6932, 20.3836, 18.2700 g, 17.2760, 16.8480 g/L. Flame retardant particle size is 0.6～0.9 mm,the pre-foaming time is 1, 1.5, 2, 2.5, 3 min, and the bead density is 26.4, 25.72, 25.2, 24.64, 23 g/L.
