烘箱加热和冷却。为了提高产量，保证生产线的高速生产，在烘箱、加热、冷却部分，我公司都有独特的见解与设计。烘箱起到了去除胶片的多余水分作用外，更重要的还起到了去除内应力的作用，充分去除掉胶片中的内应力能有效防止胶片在与玻璃高温合片时的热收缩，可变热变形量控制的更好。
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:
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.
