Since the plastic itself cannot be degraded under natural conditions, the accumulated waste plastics also cause "white pollution". At the same time, waste plastics still contain huge renewable resources, and the existence of "white pollution" is a huge waste of limited earth resources. Therefore, the recycling of waste plastics is not only the key to the sustainable development of the plastics industry in this century but also an important measure to solve environmental pollution. In foreign countries, "white pollution" has attracted widespread attention from citizens to governments, from manufacturers to academia, and has made many progresses. In China, waste plastic recycling technology started late, but it has made rapid progress. Many universities, Chemical research institutes, environmental protection departments, and manufacturers have all joined the research ranks.
Waste plastic recycling technology means that the recycled plastic products are directly processed and molded after identification, classification, cleaning, crushing or dissolution, and melting, or through mechanical blending or chemical modification, and then processed and molded. Recycled plastics are plastics in different forms that still have recycling value after their service life ends. Almost all thermoplastics have recycling value. Recycled plastics will be produced due to these processes, such as the synthetic resin production process, the production and processing of plastic products and semi-finished products, the plastic logistics process and after consumer use. For example, factory waste plastic, what is produced during synthesis and processing is called pre-consumer plastic; Some material such as supermarket shopping bags, food packaging, beverage bottles and other waste plastics,what is produced after circulation, consumption, and use is called post-consumer plastic. Plastics produced before consumption are small, with stable quality and high recycling value. They are properly handled in the production process and can be completely reused. What we call recycled plastics normally refers to recyclable plastic products that lose use value after consumption and can be recycled. After recycling, concentration, classification, and scientific and reasonable disposal, plastics can obtain renewable value and realize recycling.
Therefore, MAPA has designed a new standard ACS-PRO recycling pelletizing unit for different materials. The re-optimized design of the ultra-long-diameter ratio and the design of vacuum after the middle section self cleaning filtering is especially suitable for high impurity content and heavy ink materials. The variable frequency speed regulation of the compaction chamber motor combined with the sliding door device at the feed inlet allows ACS-Pro to not only handle the recovery of loose materials, but also the recycling and pelletizing of hard plastics.
