can be put back into their blown film extruders (instead of being sold off as was mostly previously the case). These blown film extruders are equipped with discontinuous screen changers. When using the repelletised material which has been pre-filtered using the Gneuss RSFgenius, the intervals between changing screens on the discontinuous screen changers on the blown film lines is practically the same as when processing vir- gin material and the quality of the repelletised material is such that it can be used up to 100 % in place of virgin material. Thanks to the extremely efficient, unique self-cleaning system of the RSFgenius 175 on the central recycling line, the filter ele- ments on the do not need frequent replacement and the quan- tity of material lost through back-flushing is kept to an absolute minimum. The company director, Mr. Michael Oldenburg con- firmed that the Gneuss Melt Filtration System met or exceeded all the performance characteristics which were promised in ad- vance and that in spite of the tight space requirements on the existing recycling line, Gneuss were able to tailor make the installation so that it was possible to install it without needing to move the positions of the existing equipment. 35 Extrusion Asia Edition 2/2021 回收再生 ➠ Gneuss Kunststofftechnik GmbH Mönichhusen 42, 32549 Bad Oeynhausen, Germany www.gneuss.com 自 2013 年以来，奥地利挤出和回收技术公司 MAS （Maschinen- und Anlagenbau Schulz GmbH ）和荷 兰薄膜回收公司 Caroda BV 一直在薄膜回收系统的技 术开发方面开展合作。这些系统专注于具有更高 LLDPE 含量的 LDPE 工业薄膜以及农用薄膜。 Since 2013, Austrian extrusion and recycling technolo- gy company MAS-Maschinen- und Anlagenbau Schulz GmbH and Dutch film recycling company Caroda BV have been cooperating in the technological develop- ment of film recycling systems. These systems focus on LDPE industrial films, with a higher LLDPE content, as well as agricultural films. 因 LDPE / LLDPE 废薄膜再造粒新工艺技术而获奖 Recycling: Awarded for New Process Technology in Regranulating LDPE / LLDPE Waste Films 图2:MAS授权签署人及销售经理Stefan Lehner展示了与Caroda 共同开发的LDPE/LLDPE回收再生薄膜。薄膜的质量性能有了显 著的提高 (图片:MAS) Picture 2: MAS authorized signatory and sales manager Ing.
