What is a plastic washing recycling machine? – Suzhou Polytime Machinery Co., Ltd.

China is a big packaging country in the world, with a complete industrial system including packaging product production, packaging materials, packaging machinery, and packaging container processing equipment, packaging design, packaging recycling, and scientific and technological research, standard testing, packaging education, and so on. The reuse of packaging is a golden mountain, and the plastic that poses the greatest threat to environmental pollution is the focus of recycling. Starting from the principle of human survival of protecting the environment and saving resources, countries all over the world now attach great importance to the recycling of plastic waste, which is an effective measure to take the road of sustainable development and circular economy.

Why does plastic need recycling?

Many plastic products have little purchase value and are difficult to recycle, but they are very difficult to recycle, and the pollution to the environment is very terrible. Plastics are difficult to be biodegraded. It takes several generations to degrade in the natural state, and may even take more than 500 years. The traditional treatment of waste plastics is landfill and incineration. Landfills not only need to occupy a large number of sites. If the anti-seepage measures are improper, it is very easy for the leachate to enter the surrounding surface water or soil, which poses a long-term serious threat to the environment around the landfill and the health of residents. Direct incineration of waste plastics may also produce dioxins to pollute the atmosphere. After incineration, toxic and harmful substances in furnace bottom ash are further enriched, which still needs landfill or further harmless treatment.

Therefore, it is more advantageous to recycle and reuse waste plastics after sorting. Different plastics can be collected, classified and granulated, and used as recycled plastics. Plastics can also be reduced to monomers through pyrolysis and other technologies to participate in polymerization again, to realize the recycling of resources. The recycling of waste plastics is not only environmentally friendly but also can be reused to save resources.

What is plasticization regeneration?
Plasticization regeneration refers to the re-plasticization of waste plastics after heating and melting, to restore the original properties of plastics and make use of them, including those whose properties are lower than the original requirements. Plasticization regeneration can be divided into simple regeneration and compound regeneration.

Pure recycling refers to the recycling and plasticization of leftover materials, gates, waste defective products, and residues generated in the process of resin production plants, plastic production plants, and plastic machining, including some single, batch, clean, and once used waste plastics, waste plastics for one-time packaging and waste agricultural film, which is recycled as secondary material sources. Purely recycled materials are recycled materials that restore the original properties of plastics.

Compound regeneration is mostly carried out by township enterprises and small and medium-sized factories. However, whether it is sold by plasticizing, regeneration, and granulation, or directly mixed into the molding production of products, and used as a secondary material source, it must be accurately classified and selected, and the impurities and oil stains must be strictly removed before the recycled materials can be mixed into the products according to a certain proportion. The quality of composite recycled materials is generally lower than that of purely recycled materials.

What is a plastic washing recycling machine?
A plastic washing recycling machine is the general name of machinery for recycling waste plastics (daily life and industrial plastics). Plastic pyrolysis technology is only in the experimental research stage, so plastic waste recycling machine mainly refers to waste plastic recycling and granulation equipment, including pretreatment equipment and granulation equipment.

The so-called waste plastics pretreatment refers to the screening, classification, crushing, cleaning, dehydration, and drying of waste plastics. Each link has its corresponding mechanical equipment, namely pretreatment equipment. Plastic granulation refers to the plasticization, extrusion, wire drawing, and granulation of broken plastics, mainly including plasticization and extrusion equipment and wire drawing and granulation equipment, namely plastic granulator .

Every country in the world attaches great importance to the research on the recycling of waste plastics and has been constantly improving the recycling process and equipment of waste plastics. Suzhou Polytime Co., Ltd. is a high-tech enterprise specializing in the development, production, sales, and service of plastic washing recycling machines, extruders, and granulators.
