浙江工业大学环境学院老师需要做PE的相关实验,要求是要将PE颗粒压成纸张薄厚或者研磨粉碎后达到微米级,以便在仪器上进行观察。
众所周知,聚乙烯(polyethylene ,简称PE)是乙烯经聚合制得的一种热塑性树脂。在工业上,也包括乙烯与少量α-烯烃的共聚物。聚乙烯无臭,无毒,手感似蜡,具有优良的耐低温性能(最低使用温度可达-100~-70°C),化学稳定性好,能耐大多数酸碱的侵蚀(不耐具有氧化性质的酸)。常温下不溶于一般溶剂,吸水性小,电绝缘性优良。综合考虑,采用我公司的多样品组织研磨仪研磨对样品进行前处理。
实验目的: 检测不同PE材料的特性
实验地点: 浙江工业大学环境学院
实验材料和器具:
样品:不同种类的PE材料
仪器:全自动样品快速研磨仪(上海净信JXFSTPRP系列)
配件:钢罐一套
实验步骤:
1、将预处理过冷冻的样品加入到钢罐内,再放到液氮内冷冻几分钟;
2、将适配器装入净信研磨仪中;
3、设定好运行参数;
4、启动仪器至研磨程序结束,重复步骤;
实验结果:
