Extrusion Asia Edition 2-2018

马格齿轮泵，现在已能提供专门设计用于高熔体压力的 x6等级的型号，以及适合于各种各样粘度的产品。当重点开 发型号为EP和EV的压力最大化和容积最大化产品的同时，在 Fakuma 展出了越来越受欢迎的GU型号系列产品。一如既 往，对于x6 等级的齿轮泵，为了提高产品质量、容积效率和 稳定性以及进一步提高生产过程的安全性，马格对所有的部 件从齿轮、轴、轴承直到密封都进行了彻底的改进，优化了 零件的相互作用功能。 在Fakuma 展会上，马格展出了型号为PRIMO 200 E 的 造粒机，这是源自于其WSG干式切粒拉条造粒系统，用于可 靠地生产高质量圆柱形粒子或微颗粒，非常适合进一步加 工。与 PRIMO E 家族系列所有型号一样，系统配置可变是其 特色，用于加工软的、脆的或粗糙的聚合物。快速更换刀具 和辊筒可以灵活地适配特殊产品的要求，为更换产品提供了 最佳的灵活性。由这一系统制出的粒子可根据手头的特定任 务对重量和长度进行无限调节。拉伸方向的宽度是200mm， 拉伸速度可高达120米/分，最大产量1500千克/小时。 Fakuma 2018上展出的PEARLO® 160是马格高性能水 下造粒系统新家族的一部分。这一系列产品的开发目标是用 于生产球形塑料粒子。结合了来自Gala 和 Automatik的技 术，用于高效和灵活地开展高端应用，产量范围从个位数开 始，直到36，000千克/小时。紧凑型模块化的设计，只需要 非常小的占地面积进行生产。电子控制的EAC技术保证了工 作时切粒刀的精密定位，因此能够不间断地长时间运行，制 造出始终如一的高质量粒子。典型的应用范围包括生产木粉 和天然纤维填充混合料，热塑性塑料弹性体、橡胶和热熔 胶。 Fakuma 2018上展出的ECO 200高性能熔体过滤器来自 Ettlinger ，如同较大规格的ECO 250，设计用于能够非常自 由流动的物料如污染严重程度1.5%以下的PET和PA，但同样 适合于聚烯烃和聚苯乙烯。典型的应用是混合过滤凝胶和结 块，特别是来自于回收PET瓶的铝、纸、硅胶和PVC成分。 现在过滤等级能达到特别高的60微米，可理想地用于“瓶到瓶 ”回收利用，满足极高的质量要求。得益于其效率，ECO熔体 过滤器可以直接整合到生产效率高达1000千克/小时（型号为 200）或3000千克/小时（型号为250）的PET热成型生产 线，帮助改善设备的实用性并提高成本效益。 M aag gear pumps, now available in an x6 class version, are designed for particularly high melt pressures, and suitable for a wide range of viscosities. While the focus in developing the EP and EV types was on maximizing pressures and volumes, the model presented at Fakuma forms part of the more in de- mand GU line of products. As generally for the x6 versions, Maag has completely revised all its components, from the gears and shafts to the bearings and seals, and has optimized the functional interaction of the components in order to enhance product quality, volumetric efficiency and the consistency and safety of the production process even further. 45 Extrusion Asia Edition 2/2018 At Fakuma, Maag presented a PRIMO 200 E model pelletizer from its WSG dry-cut strand pelletizing systems range for the reliable production of high-quality cylindrical pellets or micro- pellets ideally suited to further processing. Like all the models in the PRIMO E family, it features a variable system configuration for the processing of soft, brittle or abrasive polymers. Quick tool and roller exchange enables flexible adaptation to specific production demands, delivering optimum flexibility for product changes. The pellets created by this system can be infinitely ad- justed in terms of weight and length to the specific task at hand. With a 200 mm draw-in width, it is designed for draw-in speeds up to 120 m/min and a maximum throughput rate of 1500 kg/h. The PEARLO ® 160 presented at Fakuma 2018 forms part of a new family of Maag high-performance underwater pelletizing systems. This product line was developed for the production of spherical plastic pellets. It combines technologies from Gala and Automatik for highly efficient and flexible deployment in high-end applications at throughput rates starting in the single- digit range and extending up to 36,000 kg/h. Compact and modular in design, they require only a very small footprint in production. The electronically controlled EAC technology en- sures precise positioning of the pelletizing knives during opera- tion, and hence long runtimes free of interruptions with consis- tently high pellet quality. Typical applications also include the production of wood- and natural fiber-filled compounds, ther- moplastic elastomers, rubbers, and hot adhesives. The ECO 200 high-performance melt filter from Ettlinger pre- sented at Fakuma 2018 is – like the larger ECO 250 version – designed for very free-flowing materials such as PET and PA with pollution severities up to 1.5 %, but is also suitable for po- lyolefins and polystyrenes. Typical applications are compoun- ding and filtration of gels and agglomerates, in particular of aluminum, paper, silicone or PVC constituents from recycled PET bottles. The now available extra-high filtration grade of 60 µm is ideal for bottle-to-bottle recycling, with its extremely high quality demands. Thanks to their efficiency, the ECO melt filters can be integrated directly into PET thermoforming lines, where their throughput rates of up to 1000 kg/h (type 200) and 3000 kg/h (type 250) help to improve machine availability and enhance cost-effectiveness.
