PVB中间膜pvb胶膜生产线品牌 PVB薄膜设备

PVB玻璃夹层膜厚度一般为0.38mm和0.76mm两种，建筑级pvb中间膜机组，对无机玻璃具有良好的粘结性，具有透明、耐热、耐寒、耐湿，机械强度高等特性。 PVB薄膜主要用于夹层玻璃，是在两块玻璃之间夹进一层以聚乙烯醇缩丁醛为主要成分的PVB薄膜。

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:

1、适应众多物料体系的不同类型加工1、适应众多物料体系的不同类型加工
2、从上料到收卷，全套集成，可以做交钥匙工程
3、产量大、耗能低，自动化程度高。

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。
