Extrusion Asia Edition 2-2019

37 Extrusion Asia Edition 2/2019 增加,新型的数字化方案的要求越来越迫 切。 IO连接是世界范围内的传感器数字 化连接的标准技术。通讯会在点到点之 间连接的时候发生而且还不是通过一个 现场总线。IO连接是制造商独立而且在 工业自动化领域变得越来越普及。 大多数知名的控制器生产商提供IO 连接技术, 要么装在控制器内,要么装在 通过总线连接的区域里。 传统的压力传感器带有模拟输出信 号不仅仅测量熔体的加工压力, 内部信 号的准备很久前就已经数字化了。作为 结果,这可以用来提供有价值的信息来简 化维护,增加安全性并改善可用性, 预防 性维护和条件监控可以减少停工时间和 优化加工安全性能, 熔体压力传感器如 果能公开这些数据就可以在这点上有所 表现, 但是通讯仪表往往被限制为单通 道并仅仅只有一个测量数据。 格诺斯IO连接传感器提供了显示所 有这些信息的可能性。已被证明的传感 器技术结合智能化和数字化不单单提供 传感器电子元件温度的监控,同时也记录 在不同压力负载下的操作时间。这种情 况下,操作工就可以非常清楚在操作过程 中的状态, 比如电子元件筒体头部由于 安装位置而受到了高温辐射的影响或者 传感器一直在测量范围的最高数值下进 行工作。 另外, 格诺斯测量技术将会展示为 整条生产线提供熔体压力传感器和变送 器,温度传感器及相关配件。 New Rotary Filtration System SFneos, Second Generation Multiple Screw Extruder MRS and more n Gneuss Filtration Technology will exhi- bit several different models of their pa- tented Rotary Filtration Systems. These continuous filtration systems are charac- terized by a filter disk on which the screen cavities are located in a ring pat- tern. Screens can be changed on the part of the filter disk that is not active in the melt channel, while the production pro- cess continues to run without any inter- ruptions or disturbances. The new model SFneos was developed to combine the charactertistics of several older models into one simple and cost- efiicient solution, offering the following advantages: • Constant pressure guaranteed – even during screen changes • Suitable for most types of polymers and viscosities • Compact design thanks to an enlarg- ed active screen area (up to 2370 cm 2 ) • Simple and safe handling and opera- tion with several screens accessible for screen changes • Very cost effective thanks to its im- proved design The SFneos is the ideal filtration system for applications that benefit from a con- tinuous, pressure and process constant screen changer, but that don’t require back-flushing. The SFneos 90 on display has an active screen area of 260 cm 2 . Gneuss’ top model, the RSFgenius, ope- rates with an integrated self cleaning system for very demanding applications and highest quality requirements. Screens can be automatically re-used up to 400 times and filtration finenesses be- low 10 microns/1200 mesh are available. There will be different sizes on display, including an RSFgenius 330, which will be the biggest filter on the Gneuss booth this year. It offers an active filtration area of 2150 cm 2 and will be shipped to an end customer in Southern Europe after the show. Last but by no means least, Gneuss will exhibit two KF screen changers, a KF 75 with an active screen area of 44 cm 2 and a KF 110 with an active screen area of 95 cm 2 . The KF 110 will be installed in a blown film line at Brazilian machinery manufac- turer Carnevalli’s booth (hall 16, booth C70). The KF series of continuous filtra- tion systems is designed specifically for applications with frequent material type, grade or color changes as well as for high pressure applications like blown film. Gneuss also offers a new semi-contin- uous model, the CSFprimus. This model is used as a pre-filer, safety filter or in ap- plications with little contamination and is characterized by a very large active screen area for its small footprint. Gneuss Extrusion Technology will show a complete Gneuss Processing Unit (GPU) including a second generation Multi Ro- tation System MRS110 extruder, a fully automatic melt filtration system RSFgeni- us 90 and a new style online viscometer VIS, for the processing of 600 kg/h of undried and uncrystallized polyester (PET). The Gneuss Processing Unit (GPU) has been available for more than a decade now and has proven itself for the repro- cessing of highly contaminated materials without pre-drying, especially bulky PET waste such as post-consumer bottle flak- es and industrial waste from fiber and film manufacture as well as polystyrene, nylon and other hydrophil polymers. A Gneuss Processing Unit consists of a Gneuss MRS extruder with its unmatch- ed devolatilization and decontamination performance in combination with a highly-efficient Gneuss Rotary Filtration System and an online viscometer VIS for intelligent dynamic viscosity control. 在格诺斯生产车间内的几台格诺斯加工装置 A number of Gneuss Processing Units in one of Gneuss production halls
