What are the treatment method of waste plastics? – Suzhou Polytime Machinery Co., Ltd.

In daily life, plastic products can be seen almost everywhere. It does provide us with a lot of conveniences, but it also brings a lot of white pollution. Due to their lightweight, waste plastics often fly with the wind in the air, float on the water, or are scattered in the urban area and on both sides of the road, resulting in visual pollution, which seriously affects the overall beauty of the city. At the same time, due to the polymer structure of plastics, natural degradation takes more than a century. Therefore, when waste plastic packaging enters the environment, it will cause long-term ecological problems. Recycling waste plastics can alleviate the pressure of resources, save the land and obtain certain economic benefits. Therefore, the world is constantly actively exploring and trying to find a better solution to waste plastics.

What are the components of plastics?

Plastic (also known as synthetic resin) is a kind of high molecular organic compound. Its main component is resin, and various additives are added to meet different needs. Among them, resins are divided into two categories: natural resins and synthetic resins. At the same time, the performance of resin determines the basic performance of plastics, which is a necessary component. Additives (also known as additives) also have a very important impact on the basic properties of plastics. It can improve the forming and processing performance of plastic parts, reduce the cost in the production process and change the service performance of plastics.

At room temperature, plastic can maintain a given shape. To make it into a certain shape, it must be under specific temperature and pressure conditions.

What are the treatment methods of waste plastics?

1. Landfill method

The landfill method is to send waste plastics to landfills as waste. This method is simple and easy and is still often used in various countries. However, due to the large volume of plastic and the limited amount of waste that can be placed, it will also cause waste of land resources. Moreover, after landfill, the harmful substances in the waste will penetrate the ground, affect the soil structure, pollute the groundwater and cause secondary pollution. Moreover, the landfill of a large number of reusable waste plastics has caused a waste of resources, which is not in line with the sustainable development advocated by our country.

2. Thermochemical recovery method

The thermochemical recovery method can be divided into the incineration method and the pyrolysis method.

Incineration means that a large amount of heat energy can be obtained and the land occupation can be reduced by burning waste plastics. The method has the advantages of convenient operation and low cost. However, in the process of combustion, harmful gases will be produced, resulting in air pollution. Pyrolysis refers to the irreversible thermochemical reaction of organic solid waste to produce combustible gas, tar, and coke in the absence of oxygen or oxygen. The pyrolysis process has complex processes, high equipment requirements, high production costs, difficult recovery, and limited application range.

3. Mechanical recovery method

Mechanical recovery methods are mainly divided into two categories: simple regeneration and modified regeneration. The mechanical recovery method is green, effective, and widely used. Its process is to remove impurities, crush, clean, and dry waste plastics, and finally dissolve, granulate and regenerate them to make new products.

What are the applications of plastic recycling machine in plastic recycling process?
Plastic recycling machine is mainly used for mechanical recycling of waste plastic products. A plastic recycling machine is the general name of the machinery for recycling waste plastics. It mainly refers to the waste plastic recycling and granulation equipment, including pretreatment equipment and granulation equipment.

In the recycling process, the waste plastics are screened, classified, crushed, cleaned, dehydrated, and dried by the pretreatment equipment. The corresponding pretreatment equipment shall be selected according to the link, plastic raw materials, and output. After that, the broken plastic is plasticized, extruded, drawn, and granulated by the plastic extruder and plastic granulator, and finally, the purpose of recycling is achieved.

There are many treatment methods for waste plastics, among which the mechanical recovery method is green, has a good recovery effect, and is widely used. Traditional plastic recycling machines need to crush plastic, which increases the recycling cost, reduces the recycling efficiency, and makes the working environment of workers worse. The design improvement of plastic recycling machines through high and new technology is the development director for a long time in the future. Suzhou Polytime Machinery Co., Ltd. is a high-tech enterprise with science and technology as the leading and quality of life. At present, it has developed into one of the large extrusion equipment production bases in China. If you are engaged in waste plastic recycling, you can consider our high-tech products.
