21 Extrusion Asia Edition 1/2020 ➠ Nordson Polymer Processing Systems www.nordsonpolymerprocessing.com ➠ Useon Extrusion Machinery Co., Ltd. Nanjing, Jiangsu, China www.useon.com installed a 70,000 ton per year polypro- pylene pelletizing line that incorporates a BKG ® underwater pelletizer from Nord- son Corporation. The new line, which is up and running at the facility of an Indonesian customer, is powered by Useon’s SAT-X 175 co-rotat- ing twin screw extruder. The unit has a 2,000 kW motor and Useon’s patented high-torque gearbox. The throughput of the line is 8 to 10 tons/hour. “The start-up is the culmination of a me- ga-integrated polyolefin pelletizing pro- ject in which Useon was responsible for design, manufacturing, installation, and commissioning,” said Allen Zhang, sales manager for Useon. “The size of the pro- ject and our comprehensive role in it marks a milestone for made-in-China twin-screw technology in a market until now dominated by Western suppliers.” The pelletizing component from Nord- son includes the BKG AH D 300 under- water pelletizer, with throughput capabi- lity up to 35 tons per hour, and the Opti- gon™ 5 automatically self-cleaning 在印度尼西亚的新聚丙烯造粒生产线，采用Useon的SAT-X 175同向双螺杆挤出机，最 显著的位置是滑动底座安装的BKG ® 水下造粒机 New polypropylene pelletizing line in Indonesia, with Useon’s SAT-X 175 co-rotating twin-screw extruder; skid-mounted BKG ® underwater pelletizer is in foreground water and dryer system, with throughput up to 15 tons per hour. BKG pelletizers are widely used in China and elsewhere, noted Aaron Kong, Nordson sales director for China. “To support this market, last year we started up a new pelletizing laboratory line at our facility in Shanghai, including a 300 kg per hour twin-screw extruder. It is used by our direct customers as well as OEM companies like Useon, whose cus- tomers can run trials in our lab to de- monstrate our BKG equipment.” Since established in 2006 in Nanjing, China, Useon Extrusion has successfully delivered more than 2,600 twin- and sin- gle-screw extrusion lines worldwide for polymer processing applications includ- ing compounding, direct extrusion, foam extrusion, and recycling. n 系统供应商ProTec Polymer Pro- cessing的拉挤生产线用于生产长纤维 增强热塑性（LFT）复合材料，在亚洲 取得了越来越大的成功。 来自江苏省苏 州市的苏州双威聚合物有限公司，目前 正在使用两条ProTec LFT拉挤生产线进 行造粒，是对此满意的中国客户之一。 2017年 ， 这 家 混 料 供 应 商 从 ProTec购买了第一条32股LFT拉挤生产 线 ， 该 生 产 线 的 造 粒 生 产 能 力 为 500 kg / h，在2019年他们又购买了第 二条64股且产量加倍的装置。在过去的 一年中，该公司还订购了两套SOMOS Gramix S9重力定量加料和混合系统， 它们将于今年投入生产。 源自“拉”和“挤出”的“拉挤成型”工艺 可用于生产各种纤维增强塑料。 Pro- Tec的拉挤生产线使塑料粒子制造商能 够实现自动化高效生产LFT粒子。 纤维 和高分子材料的组合实际上可以使用任 何普通的热塑性塑料，并根据需要采用 玻璃纤维、钢纤维、芳族聚酰胺纤维或 碳纤维进行增强。 仅需对现有的生产线进行少许改动 和增补，即可完成新的提速升级。 改动 包括添加预热器和对模具的几何形状进 行优化。这样一来，可以更快地将纤维 调节至所需温度，从而确保以显著提高 的生产率进行完美的浸渍。 第二个水浴 槽也可提高冷却能力。 ProTec同样修 改了造粒机。在高速机型中，特殊布置 的旋转刀可高速切粒，以达到6至12 mm的最佳切粒长度。 Success in China with LFT Pultrusion Lines n Systems supplier ProTec Polymer Pro- cessing is enjoying ever greater success in Asia with its pultrusion lines for pro- ducing long fiber reinforced thermoplas- tic (LFT) compounds. Suzhou Sunway Po- lymer Co. Ltd. from the city of Suzhou in Jiangsu Province is one of the satisfied Chinese customers and is now producing pellets using its two ProTec LFT pultru- sion lines. In 2017, the compounder purchased its first 32 strand LFT pultrusion line from ProTec which has a pellet production ca- pacity of 500 kg/h, while a second unit 在中国的长纤维增强热塑 性塑料粒子拉挤生产线取 得成功
