Extrusion Asia Edition 1-2023

布吕克纳薄膜拉伸生产线 Brückner film stretching line 31 Extrusion Asia Edition 1/2023 • 智能化的拉伸烘箱管理，确保每年节约能源大约160万 kWh。 • 符合空气流动力学的区域分隔设计增加了收卷机上A级薄 膜的比例，减少了生产废料，并降低了单位能耗。 单一材料的薄膜 – 循环经济的解决方案： 单一材料解决方案，是新应用的理想选择，因为它们保 证了在废塑料分离中良好的分类能力，并保证了较高的回收 材料质量。布鲁克纳机械公司已经开发了单一材料的包装解 决方案，完成了闭环式的塑料包装生命周期。除了最先进的 材料BOPP和BOPET之外，新的机会正在向BOPE敞开。 • 最近成功的推出了几项PP单一材料包装产品的开发：比 如，软包装袋，以前复杂的复合材料现在被基于BOPP和 CPP的全聚丙烯产品所取代，甚至可适用于耐蒸煮的应用。 • 从布鲁克纳试验生产线的测试生产清晰的证明，消费后废 弃的回收PET材料，可按50%以上的比例添加到新的纯净原 材料中，而不会有任何质量上的损失。 • 生产BOPE薄膜的生产线概念，也可以具有生产BOPP薄 膜的灵活性。薄膜生产商可以选择工作宽度6.6米，产量3吨 ／小时，或选择工作宽度8.7米，产量5吨／小时的生产线。 特种薄膜生产线：进一步的新发展 布鲁克纳的特种膜生产线, 在全球都有很大需求, 特别是 对于快速增长的电动车和新能源行业. 专利的LISIM线性电机 同步拉伸工艺非常适用于高效生产各种具备最佳性能的特种 薄膜： • 电池隔膜和电容器薄膜：在这些领域中，以前的生产线宽 度将分阶段从5.5米进一步增加到６米以上，产量将相应的增 加20%以上。 • 布鲁克纳特殊的BOPET厚膜生产线为绿色能源解决方案提 供了支持，生产用于光伏板的高性能太阳能背板。 • 工业薄膜可用于各种广泛应用：绝缘薄膜，复合薄膜，电 缆电线的电气外壳，电机和变压器的薄膜开关，窗膜，离型 保护膜，电机绝缘薄膜。 • 柔性印刷电路和电子产品：用于RFID天线的基材，有机显 示器，有机光伏，医疗传感器，印刷电池的基材。 I n addition to the developments for the rapidly developing cir- cular economy, Brückner Maschinenbau is also sticking to its ambitious goals for further increasing efficiency in film produc- tion. This means decreasing use of raw materials, ever lower energy consumption and "zero waste" in film production. At Chinaplas 2023 in Shenzhen, latest solutions for the film stretching of the future will be presented in Hall 10, Booth 10Q21 . Higher efficiency – lower energy consumption The more efficient and higher output a film stretching line is, the lower the specific energy consumption. These parameters can mainly be influenced by the line speed and the line width. At Chinaplas Brückner Maschinenbau will present correspond- ing new line concepts for packaging film production: • Production of the most popular packaging film BOPP with a line concept with an annual output above the current bench- mark of 60,000 to 70,000 tons per year. This also means a two- digit lower energy consumption, based on 1 kg of film. • BO films made of polyamide (BOPA): New line types with up to 80% more output – based on an increase in production speed from 220m/min to 350m/min and line widening from 6.6m to 7.4m. More sustainability in film production • A new type of direct recycling saves energy, conserves raw material and comes very close to the goal of "zero waste" in production • Intelligent stretching oven management ensures an energy saving of around 1.6 million kWh per year • Aerodynamic zone separation increases the proportion of A- grade film on the winder, reduces production waste and lowers specific energy consumption Mono-material films – solutions for a Circular Economy: Mono-material solutions are ideal for the use in new applicati- ons since they guarantee good sortability in waste separation and high-grade recycling material quality. Brückner Maschinen- bau has developed mono-material packaging solutions to close the life cycle of plastic packaging. Besides the state-of- the-art materials BOPP and BOPET, a new opportunity is opening up with BOPE. • Several developments for PP mono-material packaging have been successfully launched re- cently: E.g. flexible pouches, where complex la- minates are now substituted by all-polypropyle- ne versions based on BOPP and CPP or even re- tortable applications • Trials on the Brückner laboratory line clearly showed that post-consumer waste recylate PET can be added to the virgin material in a propor- tion of above 50% without any losses in quality • Line concepts for the production of BOPE
