塑料吹膜机由于自身一些因素而造成薄膜产品出现问题,皱折和膜泡不稳定常出现的两个问题；薄膜厚度不均匀，冷却风环的风量不稳定，膜泡冷却不均匀; 这是什么原因造成的呢?
世研机械来为大家解答。
1、薄膜出现皱折故障
原因:①薄脱厚度不均匀;②冷却效果不够,③吹胀比太大，造成膜泡不稳定,左右来回摆动,容易出现皱折;④人字夹板的夹角过大，膜泡在短距离内被压扁，因此薄膜也容易出现皱折，⑤牵引辊两边的压力不一致，一边高一边低,⑥各导向辊之间的轴线不平行,影响薄膜的稳定性和平展性,从而出现皱折。
解决力法:调整薄膜的厚度,保证厚度均匀一致:②提高塑料吹膜机冷却效果，保证薄膜能够充分冷却:③适当降低吹胀比;④适当减小人字夹板的夹角:调整牵引狠的压力，保证薄膜受力均匀; ⑥检查各导向轴的轴线，并使之相互平行。
2、塑料吹膜机膜泡不稳定故障
原因:挤出温度过高，熔融树脂的流动性太大，粘度过小，容易产生波动,②挤出温度过低,出料量少,冷却风环的风量不稳定，腹泡冷却不均匀:④受到了外来较强气流的干扰和影响解決办法:①调整挤岀温度, ②调整挤出温度;③检査冷却风环,保证四周的送风量均匀一致,④阻止和减小外界气流的干扰。以上就是关于“塑料吹膜机薄膜皱折及膜泡不稳定故障解决方法”的介绍,希望对大家有帮助。更多关于塑料挤出机、塑料吹膜机的问题,欢迎咨询世研机械。
