浙江工業(yè)大學環(huán)境學院老師需要做PE的相關實驗,要求是要將PE顆粒壓成紙張薄厚或者研磨粉碎后達到微米級,以便在儀器上進行觀察。
眾所周知,聚乙烯(polyethylene ,簡稱PE)是乙烯經聚合制得的一種熱塑性樹脂。在工業(yè)上,也包括乙烯與少量α-烯烴的共聚物。聚乙烯無臭,無毒,手感似蠟,具有優(yōu)良的耐低溫性能(最低使用溫度可達-100~-70°C),化學穩(wěn)定性好,能耐大多數(shù)酸堿的侵蝕(不耐具有氧化性質的酸)。常溫下不溶于一般溶劑,吸水性小,電絕緣性優(yōu)良。綜合考慮,采用我公司的多樣品組織研磨儀研磨對樣品進行前處理。
實驗目的: 檢測不同PE材料的特性
實驗地點: 浙江工業(yè)大學環(huán)境學院
實驗材料和器具:
樣品:不同種類的PE材料
儀器:全自動樣品快速研磨儀(上海凈信JXFSTPRP系列)
配件:鋼罐一套
實驗步驟:
1、將預處理過冷凍的樣品加入到鋼罐內,再放到液氮內冷凍幾分鐘;
2、將適配器裝入凈信研磨儀中;
3、設定好運行參數(shù);
4、啟動儀器至研磨程序結束,重復步驟;
實驗結果:
