Extrusion Asia Edition 1-2022

37 Extrusion Asia Edition 1/2022 许多客户已经成功地将该系统用于色母粒的生 产和研究环境中。一家研究机构正在使用 ECON Hy- brid 50，这家客户的经营者说道：“我们正在开发基 于木粉填充的木塑复合新材料。我们使用的水下造粒 系统的木粉填充料含量约为 70% 到 75% 。高于这个 比例时，我们切换到空气造粒系统。由于空间和投资 有限，我们现在采用一条复合生产线，可以使用两种 技术，这对我们来说是一个很大的优势。” 该技术的一个特点是所有组件都已安装在基础 框架上并相互连接。只需几个简单的步骤即可转换连 接到相应的输送和冷却管道及切割室。控制系统的操 作切换简单、可视化，可确保操作员的最大安全性。 除了高度的灵活性之外，该机器的特殊优势在 于两种技术都使用相同的模头板单元。这意味着在熔 体到达造粒机之前，设备无需进行任何变动。这样就 降低了投资成本。模头板单元本身具有经过验证的全 球独一无二的ECON“热隔离”技术。与传统系统相 比，热隔离技术减少了切割后的粘连，模头板单元产 生的压力也大为减小。如果压力过大，生物塑料尤其 容易过热，这会降低产品质量，甚至导致材料在此过 程中“烧焦”。使用 ECON 技术，这种风险显着降低。 热分离技术可防止模头板孔凝结堵塞——因此可以实现较高的 产量。自从首次开发“小型”机器以来，这种创新的造粒系统也 成功地用于大型生产工厂，例如 ECON Hybrid 1500 型设备。 该机适用于高达 2,500 kg/h（水下造粒系统）和高达 1,200 kg/h（空气造粒系统）的产量。因此，客户可以在同一 条复合生产线上采用两种技术和更大的批量生产。产品转换所 需的时间通常不会比另一种材料的准备时间长。 混合料设备可以选择配备所有已知技术，例如防磨损、 防腐蚀、自动带式过滤系统等。因此，客户可以在水下、空气 或混合系统之间进行选择。根据不同应用，ECON 可为每位 客户提供量身定制的解决方案。 N umerous customers are already successfully using this sys- tem for the production of masterbatches and in the research environment. An ECON Hybrid 50 is in use at a research facility whose operator says: “We are developing new materials based on wood flour-filled WPC plastics. We use the underwater pel- letizing system up to a filler content of approx. 70% to 75% with wood flour. Above this level, we switch to the air pelletizing system. Since we were limited in space and investment possibi- lities, we now use two technologies in one compounding line, which is a great advantage for us.” One special feature of this technology is that all components are interconnected to each other on the base frame. Only the cut- ting chamber, which is connected to the corresponding trans- port and cooling pipes, is converted in a few simple steps. The operating switchover in the control system ensures maximum safety for the operator and a simple, visualized operation. The special advantage of the machine, apart from its high va- riability, is that both technologies use the same die plate unit. This means that no modifications have to be made e.g. before the melt reaches the pelletizer. Ultimately, this also reduces in- vestment costs. The die plate unit itself has the proven and worldwide unique ECON technology of "thermal separation". ➠ ECON China Ltd.

Bioplastics in particular tend to overheat if the pressure builds up too much, which reduces the quality and even causes the material to "burn" during the process. With the ECON technology, this risk is significantly minimized. The thermal separation prevents the die holes from freezing – the- refore large throughput ranges are possible. Since the first de- velopment of “smaller” machines, this innovative pelletizing system is also successfully used for larger production plants, such as type ECON Hybrid 1500. This machine is suitable for a throughput of up to 2,500 kg/h (underwater pelletizing system) and up to 1,200 kg/h (air pelle- tizing system). The customer can thus produce larger batches in both techniques on the same compounding line. The switchov- er usually takes no longer than the preparations for another ma- terial. The hybrid machines can optionally be equipped with all known techniques, such as wear protection, corrosion protection, au- tomatic band filtration systems, etc. The customer can thus choose between underwater, air or hybrid systems. Depending on the application, ECON offers a tailor-made solution for every customer. ECON Hybrid 150：空气造粒系统 ECON Hybrid 150: Air Pelletizing System
