XH-430 吹膜機  XH-430 Blown Film Machine

簡介：本機主要用于檢測聚合物材料的吹膜可行性和材料內的膠質狀況，以及有色分散物、控制混合物、擠出物的分散性。

Introduction: This machine is mainly used to test the feasibility of blown film of polymer materials and the state of the resin in the material, as well as the dispersion of colored dispersion, control mixture and extrudate.

工作原理：擠出吹膜是指在一定溫度，一定剪切力的作用下使塑膠熔體連續的通過口模被擠出,由壓縮空氣吹脹，風環冷卻和變頻牽引而獲得的雙折塑膠薄膜的工藝過程。
