㈢ PE是什么材料、特点、作用

PE材料介绍常用的有三大类，即：LDPE HDPE LLDPE 三种聚乙烯的单体是一样，只不过，在合成这些聚乙烯
时，所采用的工艺条件不一样，因此，才生成三种不同的聚乙烯品种，三种材料的性能有较大的差异。

LDPE
简称LDPE
俗称花料或筒料
学名低密度聚乙烯高压聚乙烯
英文名low density polyethylene
单体乙烯------是石油提炼中产生的一种气体
本色聚乙烯本色是一种半透明白色腊状材料，比重比水轻，柔软而且有韧性，略能伸长，无毒，无味燃烧特征易燃，离火后能继续燃烧，火焰上端呈黄色，下端呈蓝色，燃烧时会熔溶，有液体滴落，无黑烟冒出，同时，发出石腊燃烧时发出的气味。
优点耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性。
缺点机械性能差，透气差，易变形，易老化，易发脆，易应力开裂，表面硬度低，易刮伤。难印刷，印刷时，需进行表面放电处理，不能电镀，表面无光泽。
用途用于挤出包装薄膜，被复薄膜，软管
用于注塑低档日用品及外壳
用于挤出吹塑容器
注塑性能低分子量的聚乙烯，熔点为120℃，非常象石腊；一般的聚乙烯熔点为140℃，分解温度为
300℃；注塑温度的可调区间较大，常用于其它原料的换料洗机用。注塑时，一般使用温度为170℃--220℃；
因是烯烃类塑料，它不吸水，生产时，不需哄干，但为了产品质量，可用60℃温度烘干1hr，以排出浮水；
聚乙烯的熔体粘度大，流长比小，薄壁制品可能缺胶，因此，浇口和流道相对较大；制品易带静电，表面易
吸尘埃。收缩率为16‰；溢边值为0.05mm

HDPE
简称HDPE
俗称硬性软胶
学名高密度聚乙烯低压聚乙烯
英文名high density polyethylene
单体乙烯---石油提炼中产生的一种气体
本色高密度聚乙烯本色是一种不透明白色腊状材料，比重比水轻，柔软而且有韧性，但比LDPE 略硬，也略能伸长，无毒，无味燃烧特征易燃，离火后能继续燃烧，火焰上端呈黄色，下端呈蓝色，燃烧时会熔溶，有液体滴落，无黑烟冒出，同时，发出石腊燃烧时发出的气味
优点耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性。表面硬度，拉伸强度，刚性等机械强度都高于LDPE，接近于PP，比PP 韧，但表面光洁度不如PP
缺点机械性能差，透气差，易变形，易老化，易发脆，脆性低于PP，易应力开裂，表面硬度低，易刮伤。难印刷，印刷时，需进行表面放电处理，不能电镀，表面无光泽。
用途用于挤出包装薄膜，绳索，编织袋，渔网，水管
用于注塑低档日用品及外壳，非承载荷构件，胶箱，周转箱
用于挤出吹塑容器，中空制品，瓶子
注塑性能一般的HDPE 熔点为142℃，分解温度为300℃；注塑温度的可调区间较大。注塑时，一般使用
温度为180℃--230℃；因是烯烃类塑料，它不吸水，生产时，不需哄干，但为了产品质量，可用60℃温度烘干1hr，以排出浮水；聚乙烯的熔体粘度大，流长比小，薄壁制品可能缺胶，因此，浇口和流道相对较大；制品易带静电，表面易吸尘埃。收缩率为16‰；溢边值为0.05mm

LLDPE
简称LLDPE
学名线型低密度聚乙烯低压低密度聚乙烯
单体乙烯---石油提炼中产生的一种气体
本色线型高密度聚乙烯本色是一种不透明白色腊状材料，比重比水轻，柔软而且有韧性，但比LDPE 略
硬，也略能伸长，无毒，无味
燃烧特征易燃，离火后能继续燃烧，火焰上端呈黄色，下端呈蓝色，燃烧时会熔溶，有液体滴落，无黑烟冒出，同时，发出石腊燃烧时发出的气味

LDPE HDPE LLDPE 三种材料的差别：LDPE 与HDPE 的差别主要是在密度上的差别，从而引起机械性能上的
差别，一个刚硬，一个柔韧；LLDPE 与它们的差别，主要是在分子结构上，LLDPE 有较多的支链，因此，这种材
料是即柔韧又刚硬。
优点耐酸碱，耐有机溶剂，电绝缘性优良，低温时，仍能保持一定的韧性。表面硬度，拉伸强度，刚
性等机械强度都高于LDPE，但低于HDPE；LLDPE 的抗穿刺性是最好的，耐撕裂，特别适宜生产薄膜，生产出的
薄膜比LDPE 薄，但强度高。
缺点机械性能差，透气差，易变形，易老化，易发脆，脆性低于PP，易应力开裂，表面硬度低，易刮伤。难印刷，印刷时，需进行表面放电处理，不能电镀，表面无光泽。
用途用于挤出包装薄膜，胶带，电缆；生产出的薄膜，也叫拟纸薄膜
用于注塑低档日用品及外壳
用于挤出吹塑容器，中空制品，瓶子
注塑性能一般的LLDPE 熔点为170℃，分解温度为300℃；注塑温度的可调区间较大。注塑时，一般使用温度为200℃--260℃；它的表观粘度大，流动性差，单独的LLDPE 难以注塑，因此，要加大注塑机的功率或加其它低分子量的塑料增加它的流动性；因是烯烃类塑料，它不吸水，生产时，不需哄干，但为了产品质量，可用60℃温度烘干1hr，以排出浮水；线型低密度聚乙烯的熔体粘度大，流长比小，流动性低于LDPE 和HDPE，薄壁制品可能缺胶，因此，浇口和流道相对较大；制品易带静电，表面易吸尘埃。收缩率为16‰；溢边值为0.05mm
