Waste plastic recycling technology application case

PET recycling technology
Waste polyester recycling is divided into physical recycling and chemical recycling. Chemical recovery is the depolymerization of solid polymer materials into smaller molecules, intermediate materials, or direct conversion to monomers. For PET, chemical recovery can break polyester chains into low molecular weight ethylene terephthalate (BHET) intermediates or completely degrade to PTA or terephthalate II Methyl ester (DMT) and ethylene glycol (EG). As the field of foods does not allow the use of physically recycled PET, advances in polyester chemical recovery technology are very important. Only the development of economic chemical recovery technology can effectively promote the reuse of this resin. At present, the cost of recycling is not as competitive as the production of PET from new raw materials, so it cannot be applied on a large scale. For PET, the traditional chemical recovery mainly has the following specific methods: methanol alcoholysis, hydrolysis and glycol alcoholysis.

New Ways to Recycle PS Foam
1, production of flame retardants. 2. Prepare impact plastic. 3, production of lightweight building insulation materials. 4, non-solvent heat medium defoaming recycling process. The process is to put waste polystyrene foam into a defoaming tank, add heat medium heated to a certain temperature, contact it with the foam and fall into the heating tank along with the defoaming shrinkage material, and then The defoamed material can be separated from the media used to obtain a defoamed recyclate. Mainly to reduce the size and facilitate transportation. 5. High recovery pyrolysis process. 6, solvent regeneration. 7, waterproof membrane. 8, fiber reinforced sound insulation board. 9, concrete foam insulation board. 10, metal, wooden doors and windows and glass sealant. 11, asphalt enhancer. 12, plant fiber reinforced insulation material. 13, impermeable leak trapping agent. 14 multi-functional resin glue. 15, with rust antirust paint 16, physical regeneration. With this process, waste polystyrene foam can be prepared into heat-insulating materials and building materials.

Discarded polyester bottles can be spun

Recently, relevant experts from the State Environmental Protection Administration China Environmental Protection Industry Association and Jiangsu Provincial Environmental Protection Agency reviewed and identified the “Recycling and Development and Utilization Technology Project of Wasted Polyester Resources” researched and developed by Jiangsu Xiake Environmental Protection Color Spinning Co., Ltd. Experts believe that the project uses waste polyester resources as raw materials, adding non-toxic and non-polluting masterbatch, and using spinning technology for colored spinning, which not only achieves the goal of reducing white pollution, protecting the environment, but also adopts resource regeneration methods. , Produced a bright color, washable and lightfast quality fiber.

Polypropylene Production Degradable Plastics

Degradable Polypropylene Package Material--Polypropylene is used as raw material, advanced technology and scientific process are adopted, and once formed by special equipment processing. Its characteristics are: 1, a short degradation time, can be completely degraded in 3-6 months. 2. The whole production process is non-toxic, odorless and pollution-free. 3, product insulation and oil resistance performance 4, the source of a wide range of raw materials, low product costs. At present, there are two major categories of products: 1, catering appliances, including fast food lunch boxes, bowls, cups and so on. 2, shopping bags, garbage bags, films and so on.
