【背景技术】【Background technique】
聚乙烯英文简称PE，它是乙烯的聚合物，无毒。容易着色，化学稳定性好，耐寒，耐辐射，电绝缘性好。它适合做食品和药物的包装材料，制作食具、医疗器械，还可做电子工业的绝缘材料等。Polyethylene, referred to as PE in English, is a polymer of ethylene and is non-toxic.

聚乙烯是目前应用最广、用量最大的塑料，从表中数据看出，聚乙烯的介子损耗小，电阻率高、击穿场强高，耐候性、工艺性好，是目前最好的电绝缘材料。但由于其工作温度低，所以主要用作通信电缆的绝缘。中密度和高密度聚乙烯的强度和硬度较高，其透水率低，多用作电缆护套。但是，聚乙烯有最大的缺点，即容易燃烧，且黑烟浓烈，因此它的应用给环境带来了许多隐患。Polyethylene is currently the most widely used plastic with the largest amount of consumption. It can be seen from the data in the table that polyethylene has low meson loss, high resistivity, high breakdown field strength, good weather resistance and manufacturability, and is currently the best electricity. Insulation Materials. However, due to its low operating temperature, it is mainly used as insulation for communication cables. Medium-density and high-density polyethylene have high strength and hardness, and low water permeability, so they are mostly used as cable sheaths. However, polyethylene has the biggest disadvantage, that is, it is easy to burn and the black smoke is thick, so its application has brought many hidden dangers to the environment.
