LLDPE除了具有LDPE的一些特性外,它还有以下几个特点:(1)LLDPE具有极好的热封性,虽然LLDPE的熔融温度比LDPE要高5℃左右,但LLDPE的热封性具有良好的似离子性能,即:像离子型聚合物surlyn那样,热封面即使有严重的污染,仍旧有高度的热封强度;热封时温度只要高于起始热封温度就可有高热封强度,而一般的塑料,如:LDPE热封温度愈高,热封强度愈大,因此,如用LLDPE为热封材料,可只需使用较低的热封温度就可达到高度可靠的热封强度,适宜于高速热合机使用;(2)LLDPE的熔融粘度相当地大,是LDPE的10倍,而且LLDPE的熔融粘度对温度不敏感,电线电缆制造所用的各种材料,不但类别、品种、规格多,而且数量大。因此,各种材料的用量、备用量、批料周期与批量必须核定。同时,对废品的分解处理、回收,重复利用及废料处理,作为管理的一个重要内容,做好材料定额管理、重视节约工作 广州电缆回收公司为了保护绝缘线芯不被铠装所疙伤,需要对绝缘层进行适当的保护,内护层分:挤包内护层(隔离套)和绕包内护层(垫层)。绕包垫层代替绑扎带与成缆工序同步进行。 ,而对加工应力的敏感性则很强,这就是说LLDPE不能用提高温度的方法来降低粘度,而只能用提高加工的速度,即:提高剪切应力的方法来提高熔融流动性,因此,加工LLDPE的螺杆设计是特殊的,主电机的功率往往是LDPE的2倍以上。我们常常用50%的LDPE+50%LLDPE的混合料来改善二者的性能,并使之可以在加工LDPE的设备上加工LLDPE。
