摘要
口模漏料是热收缩套管挤出过程中经常遇上的一个问题。它引起许多问题,从挤出管材上可见的表面缺陷到工艺紊乱,乃至热收缩套管产品报废。文章分析了口模漏料产生的原因,从优化热缩管挤出物料配方、调整优化挤出设备和模头设计优化及工艺调整三方面对预防口模漏料的发生进行了探析。
Die buildup occur frequently during extrusion process of heat-shrinkable sleeving.It causes a variety of problems,from visible surface imperfections on extrudates to process disruption and outright product failure.The causes of die buildup were analyzed in this paper.The three solutions were discussed.These may involve changes to the material,extrusion machine,or the die and the process.
