What is a plastic recycling machine and what is recycled plastic?

Plastic recycling machine is a general term for the machinery that recycles waste plastics (daily life and industrial plastics). Plastic pyrolysis technology is only in the experimental research stage, so the plastic recycling machine mainly refers to waste plastic pelletizing equipment, including pretreatment equipment and granulation equipment.

The traditional way of waste plastic treatment is landfill and incineration, landfill not only needs to occupy a large number of sites, if the anti-seepage measures are improper, it is easy to make the leachate into the surrounding surface water or seep into the soil, posing a long-term serious threat to the environment around the landfill and the health of residents. The direct incineration of waste plastics may produce dioxin pollution to the atmosphere, and the toxic and harmful substances in the ash at the bottom of the furnace after incineration are further enriched, which still need to be landfilled or further harmless treatment. Therefore, it is more advantageous to reuse waste plastics after sorting, which can be used as recycled plastics after collection, classification and granulation, and can also be reduced to monomers through pyrolysis and other technologies to reparticipate in polymerization, so as to realize the recycling of resources.

The recycling of waste plastics is not only environmentally friendly, but also can be reused to save resources.

Plastic recycling machine, also known as plastic granulator, granulator, extruder, has a single-head machine, the mother and child machine has two processes: cold pumping and hot pumping, the waste plastic is classified and crushed, and then added to the granulator to be extruded into strips, which are cooled by water and pelletized by the pelletizer to become recycled material

As the name suggests, it is a machine for the production of recycled materials, and the upstairs is more detailed.

Recycled plastic refers to the plastic materials obtained by using waste plastic products after sorting, cleaning, granulation and other processes. Due to the fact that the material has undergone thermal aging, photoaging and oxidation during multiple thermal processing and the use of previous products, its physical and mechanical properties have decreased to a certain extent compared with that of new materials. In addition, due to the instability of recycled plastics, the quality of products is different, and some plastic products may also be processed by printing, electroplating, etc., so their quality stability is poor, and should not be used to manufacture products with high requirements for performance stability, and can not be used for the manufacture of food packaging and medical products and other uses with very strict requirements for purity and impurity content.

Recycled plastic is the reuse of plastic, which is completed by the crushing operation of a mechanical blade.

Recycled plastic refers to the plastic raw materials obtained by processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, and modification, which is the reuse of plastics.

Hello, recycled plastics refer to the reuse of plastics, through pretreatment, melt granulation, modification and other physical or chemical methods to process waste plastics to obtain plastic raw materials.

It is of great help to improve the utilization rate of resources and reduce environmental pollution. Now, it has become a major force in energy conservation and emission reduction.

Recycled plastic is the process of processing waste plastic into something new, which can be used in daily life. Recycled plastic helps to conserve resources and reduce resource waste.

1. Build roads

On April 22, the 52nd World Earth Day, China's first waste plastic recycling and environmental protection road was officially completed and unveiled at the Xuhui Campus of East China University of Science and Technology in Shanghai. The innovative approach not only reduces the generation of environmental waste by "turning waste into roads", but also provides better pavement performance and durability than conventional pure asphalt pavement.

2. Leakage branches in front of food packaging containers

On November 24, 2020, the commencement ceremony of the Yingchuang Huizhi food-grade recycled polyester chip factory under Beijing Yingchuang Renewable Resources ****** (hereinafter referred to as "Yingchuang") was held in Baodi Economic Development Zone, Tianjin. The official start of the "Yingchuang Huizhi Factory" covers an area of 50 acres, and the factory will realize the processing process from domestic beverage bottles to food-grade recycled polyester chips after the completion of the factory.

3. Wood-plastic type wood

Hainan Kunlun New Material Technology Co., Ltd. will be the first plastic "waste into treasure", transformed into all kinds of wood plastic products, according to estimates, every 1 cubic meter of wood plastic materials produced, equivalent to saving 8 barrels of oil, 11 tons of standard coal, reducing wood felling, reducing tons of carbon dioxide.

4. Parade red Huimin blanket

On October 1, 2019, a military parade to celebrate the 70th anniversary of the founding of the People's Republic of China was held in Beijing. At the scene, the red carpet of 10,000 square meters laid on the exterior stage of Tiansouzhan Square is very eye-catching. It is reported that the "national flag red" carpet is manufactured by a company in Yangxin County, Shandong, which is made of first-class waste mineral water bottles as raw materials, with flame retardant, anti-fouling, and anti-ultraviolet functions, and a total of more than 40 million waste mineral water bottles, about 10 tons.

5. Sunglasses, computers and printers and other products

According to a tripartite cooperation agreement signed by Covestro, Nongfu Spring will be responsible for the scrapped 19-liter buckets and will give them to another partner, Shanghai Auxerre Material Technology (hereinafter referred to as Auxerre). The 19-litre plastic drums made of polycarbonate have an average lifespan of about one year. Every year, about 1 million buckets of these specifications meet the end-of-life standard.

China needs a large number of plastic products every year and consumes a lot of energy, and the recycling of waste plastics is a demand that advocates a low-carbon economy and society, and it is also an urgent demand. The emergence of the recycled plastic machinery industry can be said to be a "charcoal in the snow", and at the same time, this is a good opportunity and a good business opportunity for the industry itself.

The rise of an industry is inseparable from norms, and in recent years, the environmental protection and safety rectification action for the waste plastic processing market has been carried out in full swing. Small workshops with imperfect scale and lack of recycled plastic machinery technology will face pressure to survive. If the products produced are not standardized, they will need to face punishment and social accountability.

The recycled plastic machinery industry also needs to improve the production technology, reduce environmental pollution, and comprehensively consider the quality and energy efficiency of the product, so as to pursue a more comprehensive, more coordinated and more sustainable development, so as to get rid of the single, high energy consumption production mode and embark on the road of combined and intelligent production mode.

Plasticization and regeneration. That is, waste plastics are heated and melted and re-plasticized, and the original properties of plastics are restored for utilization, including the use of properties lower than the original requirements. Plasticizing regeneration can be divided into two types: "simple regeneration" and "composite regeneration".

Simple regeneration (simple regeneration).

This refers to the use of resin production plants, plastic production plants, plastic machinery processing process generated scraps, gates, waste defective products and residues, including some single, batch, clean and only once used waste plastics, disposable packaging waste plastics, waste agricultural film, etc.

In the processing of waste plastics, for simple recycling, most of the plastic factories first use the waste plastics of the factory, some are used after plasticization and granulation, some are directly used after crushing and processing, and some are neither broken nor granulated, and they are digested by the factory.

Simply recycled materials are recycled materials that restore the original properties of plastics.

Compound regeneration. The so-called utilization of waste plastics mainly refers to the recycling of those waste plastics collected from the society in large quantities, complex varieties, many impurities and serious pollution. Among these waste plastics, there are plastic parts, packaging products, fertilizer bags, cement bags, pesticide bottles, fish nets, agricultural films and packaging barrels reported for scrap in industrial and mining enterprises and agriculture, food bags, plastic bottles and cans, toys, daily necessities and cultural and sporting goods made of plastic in the lives of urban and rural people, as well as waste plastics containing a small amount of fillers and plasticizers.

The composite recycling of these miscellaneous, messy and dirty waste plastics is more complicated.

Compound regeneration is mostly carried out by township enterprises and small and medium-sized factories, but whether it is plasticized and regenerated granulation, or directly mixed into the molding production of products, as a source of secondary materials, it must be accurately classified and selected, and impurities and oil stains must be strictly removed in order to incorporate recycled materials into products in a certain proportion.

The quality of composite recycled materials is generally lower than that of simple recycled materials.
