PVB中间膜pvb胶膜生产线报价 流延膜设备

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:

PVB glass interlayer film production line is our company's latest design concept, with reference to the production characteristics of pvb interlayer film, designed and produced professional equipment. Since 2012, the company has produced 2800mm, 3550mm, 4200mm and other PVB intermediate film production lines with a maximum output of 800kg/H and a thickness of 0.38-1.5mm. The production line has the following characteristics:

目前，PVB中间膜的生产工艺主要有两种方式，一种是过辊法，一种是过水法。过辊法是采用两只辊或三只辊（有光辊，有花纹辊）流延的方式生产出胶片。过辊法投资低，技术相对成熟，设备也相对容易操作。过水法是普遍认为生产的胶片白度更好、花纹更均匀的一种工艺，它是采用水箱冷却定性而非辊筒，然后经过除水，测厚，烘箱，冷却，隔离膜复合、牵引，后收卷。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。
