| 摘 要： | 研究了热处理对聚乙烯性能的影响。不同的热处理过程使聚乙烯的吸水性能和水树枝的形成存在一定的差异，冷却快的聚乙烯吸水率大，容易形成水树枝；而冷却慢的聚乙烯吸水率小，不容易产生水树枝。在纯聚乙烯内空间电荷容易积累，在经过改性的聚乙烯中空间电荷积累减弱。这些结果可以用样品结晶过程的差异和样品结构的不同加以解释。

| Abstract: | The aggregation of polyethylene is studied under the various heat treatment. There is some difference in water absorbing and water treeing of the experiment polyethylene. The water absorbing in polyethylene with a quick cooling rate is bigger and the water treeing is easy to form than that in polyethylene with a slow cooling rate. In an addition, the accumulation of space charge in pure polyethylene is more than that in modified polyethylene. Adding the ethylene-acrylic acid copolymer (EAA) and sorbital in pure polyethylene inhibit the space charge. There is apparent effect of various heat treatments on polyethylene properties. These results were explained based on the different process of crystal and structure. |
