摘　　要：以聚乙烯(PE)为基材热缩管在辐照加工过程中,不规范的工艺参数导致生产效率低且产品合格率低。为了提高PE热缩管生产效率和降低成本,本文研究了聚乙烯热缩管不同规格的原料线材在电子加速器束下运行时的最优的线槽规格、滚筒缠绕匝数、收放线张力数值、最大运行线速;研究了不同辐照剂量对PE热缩管性能的影响,确定了该材质的最佳辐照剂量为120~140 KGy。In the process of radiation processing of Pe Heat shrinkable tube, nonstandard process parameters lead to low production efficiency and low qualified rate of products. In order to improve the production efficiency and reduce the cost of PE heat-shrinkable tube, in this paper, the optimum size of Groove, the number of winding turns, the tension value and the maximum running line speed of the polyethylene heat shrinkable tubes with different specifications are studied The effects of different irradiation doses on the properties of PE heat-shrinkable tubes were studied. The optimum irradiation doses were determined to be 120~140 KGy.
