Cracking plastic recycling problem: How to improve the quality and processing process of regeneration materials and processing processes?

The circular economy is the topic of the development of the global plastic industry today. The complexity of plastic waste is getting higher and higher. To provide the recovery rate, in addition to the sorting and cleaning, the network change system is also an important link in the entire process. The network replacement system is the final work of the entire recycling processing process. The network replacement system uses the impurities in the plastic melt for the last time to filter to produce higher -quality plastic particles. The traditional network replacement system needs to frequently replace the mesh by manual replacement, so that the plastic melt can constantly pass the filter surface. When recycling and complicated waste, the frequency of manual replacement of the network even changes every minute. Frequent network changes require multiple operators, the total production capacity cannot be improved and the material loss rate is high. In order to improve the effectiveness of the overall processing process, the use of the automatic network system to improve the quality and efficiency has become a trend. Italy FIMIC has been serving in the plastic recycling industry for nearly sixty years. The RAS series produced by FIMIC’s automatic network system, because it plays an important role in the entire recycling processing system, is welcomed by the European and American recycling operators in filtering ‘leakage fish’ and producing high particles. Leading brand of network system. In the past ten years, FIMIC has dealt with more complicated and higher impurities in response to market needs to make more fine filtration. At the same time, the best output quality plastic particles, FIMIC continuously develops research to improve the efficiency of its own products. At present, the filter made with laser drilling PIPE EXTRUSION LINE surface, the filtering accuracy is fine to 80 microns. FIMIC has been cooperating with most leaders to cooperate for decades. With its production automatic network system, it has assisted the common LDPE, LLDPE film, PP woven bags, boxes and barrels, HDPE pipelines and HDPE pipelines, and HDPE pipelines. Plastic and other plastic. In addition to the pursuit of automation in filtering technology, FIMIC also studies various plastic characteristics and improves the filtering accuracy of the network system. The LDPE, LLDPE film filtered by FIMIC automatic network system, such as a winding film with a paper label, a packaging film … After filtering, the film can be blown again, and the thickness of the film can be as low as 17 ~ 20 microns. In addition, there are cases of HDPE bottle recycling. When filtering the fineness of the 100 micron mesh, the low -liquidity of HDPE can still easily produce the output of 1500 ~ 1800 per hour. The HDPE regeneration particles produced can be used to produce high -quality HDPE pipes with high load bearing. With the promotion of cycle economic issues, plastic recycling is not limited to traditional PE plastic. The market has unlimited imagination of plastic materials that can be recycled, hoping to reduce the pollution of various plastic products to the environment, and truly implement the circular economy and recycling. Through experience, FIMIC re -examines the availability of automatic network changes. After trying and improving its own automatic network system, many previously classified plastic materials that were not easy to recycle and complicated Quality) and home appliance waste recycling. Through FimThe filtering of the IC automatic filtering system was successfully recovered. PVC will produce ethyl chloride during the processing process, and it is easy to generate corrosive acids and materials and easily degrade quickly, resulting in failure of recovery. After three years of uninterrupted testing, FIMIC successfully overcome the above problems, and develops a special automatic network system for PVC recycling. In 2019, it was successfully installed in the German gardening water pipe production manufacturer to install automatic network replacement system to recover soft and hard PVC pipes. The main recycling material of this production plant is the PVC gardening pipe, with 0.5 to 4 % PE and PA silk wire impurities with 0.5 to 4 %. Waste appliances recycling is also an important issue. Because waste appliances and plastics contain more complicated impurities, such as metal fragments, elastic bodies … Because these impurities are prone to loss of reserve, metal impurities are more likely to make the network system loss, so home appliance waste has been reduced Recycling rate. FIMIC’s RAS network system, in addition to automation function, the body design can reduce the chance of metal or other harder impurities and mesh contacts, greatly reducing the expenditure of spare equipment, thereby increasing the willingness to recycle recycling waste appliances. The waste home appliance recychers located on the Scandinavian Peninsula mainly processed the waste appliance fragments of ABS and PP. Originally using oil pressure to manually change the net, the mesh is required every ten to fifteen minutes. The two machines need a total of four operators to check whether the network needs to be changed at any time. After using FIMIC’s automatic network system, the customer used the first network for three months, and the two machines only needed one operator to check. In addition, because of the frequency of reducing the network, the overall output has increased by 20%, and the filtering accuracy can be thinner to 150 microns (100 mesh). In addition to the significant improvement of the quality of regeneration materials and the improvement of processing process efficiency, FIMIC’s network -changing system also helps more users to increase profits, greatly reduce operating costs, and promote the possibility of more circular economy operations.
