目前,发泡的聚乙烯混合物在电缆领域用作绝缘首先是用作电话电缆绝缘,得到了广泛的应用,同时改善了电缆的特性,减小了电缆的尺寸。发泡的聚乙烯混合物的成功应用,取决于许多因素,其中最重要的是正确地选择配方成分及最佳的加工(挤出)工艺。全苏电缆工业科学研究所研究的评定发泡混合物质量的新方法,能够分析发泡动力学、结构,可以对工艺性能作预先的评价,使人们能够深入而广泛地研究以确定更加精确的混合物配方成分,以及介绍了有关泡沫聚乙烯制成产品的加工工艺参数。
Foamed polyethylene blends are currently used as insulation in the field of cables, first as insulation for telephone cables and as a result are widely used, while improving the characteristics of the cables and reducing the size of the cables. The successful application of expanded polyethylene blends depends on many factors, the most important being the correct choice of formulation ingredients and the optimum processing (extrusion) process. A new method for assessing the quality of a foaming mixture, as researched by the Institute of Industrial Science, CNI, enables the analysis of foaming kinetics, structure, and pre-evaluation of process performance, allowing one to conduct in-depth and extensive studies to determine more accurate mixtures Formula ingredients, as well as introduced on the processing of foamed polyethylene products processing parameters.
