1. The recycling price of waste plastic woven bags (white) is 0.5 yuan per catty. The recycling price of waste plastic woven bags (variegated) is 0.4 yuan per catty. Transparent and clean mineral water bottles (plastic bottles) recycling price is 0.8 yuan per catty. The recycling price of variegated plastic bottles is 0.6 yuan per catty. White foam board (foam board used for packaging) recycling price is 0.3 yuan per catty.

2, the old plastic sole (polyurethane) back to the bucket trapped price is 3 yuan/kg, plastic pipes, such as PVC and PTFE, recycling prices are 3 yuan/kg and 5 yuan/kg. Please note that the above information is for reference only, and the actual recycling price may vary depending on geographical location and recycling channels.

3. The recycling price of waste plastic bottles varies greatly depending on category, color, and region. The following is the approximate recycling market for the current mainstream categories: Recycling price of common categories PET plastic bottles (mineral water bottles, beverage bottles): ordinary recycled materials 0.5-1 yuan/catty, transparent and clean mineral water bottles are about 0.8 yuan/catty, and variegated bottles are about 0.6 yuan/catty; the price of broken and cleaned PET chips is higher, reaching 5-3 yuan/catty.

4. The prices of waste plastic vats vary greatly. The mainstream recycling prices are concentrated between 1800 yuan per ton and 11800 yuan per ton, depending on the material and regional market. Ordinary waste plastic barrels by weight: generally 1-3 yuan per kilogram, and those with poor materials or impurities may be as low as 0.5 yuan/kg (1 yuan/kg). PP granules: The recycled and processed high-quality PP plastic granules are about 3200 yuan/ton.

5. The price of PE waste plastics is greatly affected by the type, purity, color, aging degree and market fluctuations. The price per kilogram is between about 0.7 yuan and 6 yuan. The prices of common types of PE waste plastic refer to the prices of different types and qualities of PE waste plastic. Generally, materials with high purity, unaged, and no impurities are more expensive.

How is plastic produced? How many types?

Reply: Domestic EVA is basically made in Beijing. It is divided into extrusion-grade type 14 (VA=14) general purpose film, type 18 (VA=18) foam, and injection-grade type 5 (VA=5) food packaging film. PVC is generally used for injection molding in Type 5 and Type 3. Excuse me, what is the Chinese of PPU plastic? Reply: PPU is thermoplastic polyurethane.

Classification of plastics There are many types of plastics, and so far, there are about 300 kinds of plastics in production in the world. There are many classification methods for plastics, and there are two commonly used ones: plastics are divided into thermoplastics and thermosetting plastics according to the different properties of plastics after heating. Thermoplastics have linear structures that soften or melt when heated, and are plastic. Made into a certain shape, hardened after cooling.

Blow molding: Also known as hollow blow molding, a rapidly developing plastic processing method.

Plastic bottle production begins with petroleum or recycled plastic sheets. Petroleum is refined to produce terephthalic acid (PTA) and ethylene glycol (MEG), which are polymerized to form PET resin, usually in the form of rice-like particles. After sorting, cleaning, crushing and melting, the recycled plastic bottles can also be made into recycled PET sheets and put into production again.

These processing methods are used to convert synthetic resins into various plastic products. For example, compression molding is mainly used for the formation of thermosetting plastics, while extrusion is suitable for the formation of thermoplastics and foams. Injection molding is a fast and efficient forming method suitable for mass production of complex parts. Blow molding is used to make hollow articles such as bottles and films. Calendering is the main method for making polyvinyl chloride films and sheets.

The plastics production process mainly includes three stages: raw material preparation, forming processing and post-processing. Each stage includes multiple key processes.

How are waste plastics classified?

1. The classification of waste plastics is mainly based on its material and use. For example, PET (polyethylene terephthalate) is often used to make POTTE bottles. HDPE (High Density Polyethylene) is another widely used plastic, and its uses include lotion containers, milk bottles and supermarket plastic bags. PVC (polyvinyl chloride) is mostly used in the production of items such as pipes, curtains, outdoor furniture and raincoats.

2. The classification of waste plastics includes PE, PP, PVC, PET, EPS, ABS, PA, etc. PE waste plastics include plastic greenhouse materials, industrial packaging films, lactic acid beverage bottles, etc. PP waste plastics include woven bags, packing belts, strapping ropes, etc. PVC waste plastics include plastic door and window profiles, pipes, etc. PET waste plastics include tea beverage bottles such as cola and Sprite. EPS waste plastics are commonly known as foam plastics.

3. Low-density polyethylene recycled materials: mainly processed from waste plastic mulch films, shed films, etc. These plastics are often used in agricultural covering and packaging materials. High-density polyethylene recycled material: mainly processed from milk bottles, hollow plastic barrels, plastic basins, barrels, etc., and used to produce plastic pipes, hollow plastic products, injection molded products, films, etc. To sum up, the recycling and classification of waste plastics is mainly based on the type of material and the variety of plastic products. Through reasonable classification and recycling, environmental pollution can not only be reduced, but also the sustainable development of the plastics industry can be promoted.

4. Classification and identification method of waste plastics: Classification according to the method of production: -Waste produced in resin production, including crispy rice in the polymerization process, waste in the compounding process and ground materials in transportation and storage. - Waste, substandard products and scraps generated during the molding process, such as cold material in injection molding, cleaning waste in extrusion molding and flash during blow molding.

5. The classification of waste plastics can mainly be carried out from the following aspects: Classification by species: ABS: acrylonitrile butadiene styrene copolymer, commonly used in electrical casings, toys, etc. HIPS: High-impact polystyrene, which has good impact toughness and is often used in daily necessities, electrical parts, etc. PP: Polypropylene is non-toxic, odorless, and has low density. It is often used in food packaging, plastic basins, etc.
