中间玻璃夹膜pvb胶膜生产线品牌 PVB中间玻璃夹膜生产线 PVB玻璃中间彩色膜

PVB中间膜是由聚乙烯醇缩丁醛树脂经增塑剂塑化挤压成型的一种高分子材料

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:

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:
