Advantages of BKG® Underwater Pelletizing Systems
Our pelletizing systems have many advantages: they enable a quicker, cleaner process, new capabilities, and a higher quality output.
- Spherical pellet shape
- Higher bulk density (5 – 10%)
- Less dust during transportation of spherical pellets
- Smaller contact areas of spherical pellets reduces stickiness
- Almost all viscosities can be processed with UWP (approx. 3 Pas to 10.000 Pas)
- Production of micro pellets
- Automated system with constant product quality, independent on operators
- Closed system with clean environment
- Flexible footprint, less space “in line”

常见问题解答
-
问： 什么是制粒机？一个： 制粒机是一种将材料变成小颗粒的机器。 市场上有三种类型的制粒机： 水下造粒机（由 BKG® 开发）、水环造粒机和拉条造粒机。 根据制粒机的类型，颗粒形状范围从球形到圆形但扁平到圆柱形，具有平坦的 90° 边缘。 我们收集的制粒机是测试热塑性塑料和其他行为类似的聚合物。
-
问： 选择水下切粒机有什么好处？一个： 通过在水下成型颗粒，该过程通常可以减少缺陷并提高所生产颗粒的质量。 此外，颗粒经过精心处理，减少了灰尘并产生了更清洁、更易于加工的产品。 水下制粒机生产的颗粒具有最高的堆积密度和最佳的流动特性。
-
问： 制粒机在挤压过程中处于什么位置？一个： 制粒是挤压过程之前的一个步骤。 它是创建最终被熔化和挤压的颗粒的过程。 在制粒之前， 换网器 用于过滤熔融聚合物中的污染物。
-
问： 造粒对聚合物复合有用吗？一个： 是的，制粒是一种聚合物复合方法。 通过制粒，您可以将非塑料（例如木材）与聚合物混合以制造新材料，例如用于户外装饰的聚合物板。 这种聚合物复合材料通常用于制造再生产品，例如用回收的瓶子制成的长凳；将瓶子熔化并与另一种材料混合，使长凳具有“混凝土”或“木质”的外观。
