中间玻璃夹膜pvb胶膜生产线定制 PVB中间膜生产线

1. Adapt to different types of processing of many material systems
2, from loading to rewinding, a full set of integration, can do turnkey projects
3. Large output, low energy consumption and high degree of automation.

At present, there are two main methods for the production of PVB interlayer film, one is the over-roll method and the other is the water-pass method. The over-roll method is to produce a film by casting two rolls or three rolls (with a light roll and a pattern roll). The over-roll method has low investment, the technology is relatively mature, and the equipment is relatively easy to operate. The water-passing method is a process that is generally believed to produce a film with better whiteness and a more uniform pattern. It uses a water tank to cool the characterization instead of a roller, and then removes water, thickness, oven, cooling, separator composite, and traction. Finally, the volume is collected. Because the over-water method has more advantages than the over-roll method, it is used by more and more manufacturers. The following points in the production process of the water-passing method require special attention:

风量、风刀的造型和设计。过多水分如果长时间滞留，对胶片质量也会产生影响，现在普遍采用刀，风刀数量已足够，关键在于风刀的设计、选择和位置。

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。
