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:
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。
PVB玻璃中间膜生产线是我公司结合国外设计理念，参照pvb中间膜的生产特性，设计生产的专业化装备。自2012年以来，公司先后生产了2800mm、3550mm、4200mm等规格PVB中间膜生产线，产量800kg/H，厚度0.38-1.5mm,该生产线有以下特点：
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。
