因为过水法产品优点多于过辊法,被越来越多的厂家所采用。过水法生产过程中有以下几点需要特别注意:
水箱的设计。水箱的大小、数量也与生产线的速度产量有直接关系,保证水箱的温度均匀、水循环不引起波动,这是重中之重。

电气控制。做为一种高端应用产品,胶片的各个指标要求都很高,只有高度智能的自动化控制才能满足高品质产品的要求。其中挤出机的压力自调,收卷的张力控制更是重要。
Electrical control. As a high-end application product, the specifications of the film are very high, and only highly intelligent automatic control can meet the requirements of high-quality products. Among them, the pressure of the extruder is self-adjusting, and the tension control of the winding is more important.
