pvb胶膜生产线报价 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.

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.

he oven is heated and cooled. In order to increase production and ensure high-speed production of the production line, our company has unique insights and designs in the oven, heating and cooling sections. The oven plays the role of removing the excess moisture of the film, and more importantly, it removes the internal stress. The internal stress in the film can be completely removed, which can effectively prevent the film from shrinking during the high temperature bonding with the glass. The amount of control is better.

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。
