PVB胶片设备pvb胶膜生产线规格

PVB胶片现市场上主要以原色胶片(用于建筑类夹层玻璃)和彩条胶片(其中彩条胶片又以蓝带和绿带为主,用于汽车前风挡玻璃).(也有其它颜色胶片.) PVB(原色胶片)外观为半透明薄膜，无杂质，表面平整，有一定的粗糙度和良好的柔软性，对无机玻璃有很好的粘结力、具有透明、耐热、耐寒、耐湿、机械强度高等特性，是当前世界上制造夹层、安全玻璃用的粘合材料，同时在建筑幕墙、招罩棚、橱窗、银行柜台、监狱探视窗、炼钢炉屏幕及各种玻璃等建筑领域也有广泛的应用

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:

电气控制。做为一种高端应用产品，胶片的各个指标要求都很高，只有高度智能的自动化控制才能满足高品质产品的要求。其中挤出机的压力自调，收卷的张力控制更是重要。
