锡华 XH-430-25-3 多层共挤吹膜机 三层共挤吹膜机

XH-430吹膜机  XH-430 Blown Film Machine

简介：本机主要用于检测聚合物材料的吹膜可行性和材料内的胶质状况，以及有色分散物、控制混合物、挤出物的分散性。

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：挤出吹膜是指在一定温度，一定剪切力的作用下使塑胶熔体连续的通过口模被挤出,由压缩空气吹胀，风环冷却和变频牵引而获得的双折塑胶薄膜的工艺过程。

Working principle: Under certain temperature and certain shear force, the plastic melt is continuously extruded through the die, and is blown by the compressed air, the air ring cooling and the frequency conversion traction. Then Obtained bifocal plastic film process.
