Recycled plastic particles have a wide range of applications. In daily life, recycled particles can be used to make various plastic bags, buckets, pots, toys, furniture, stationery and other life appliances and various plastic products. In the apparel industry, it can be used to make clothing, ties, buttons, and zippers. For building materials, plastic wood profiles derived from recycled plastic particles are used to make various building components, plastic doors and windows, and so on. In the chemical industry, it can be used to make reactors, pipes, container pumps, valves, etc., and is used in chemical production sites where corrosion and wear are solved. In agriculture, it can be used to make agricultural film, pumping pipes, agricultural machinery and fertilizers. In addition, recycled particles are also widely used in the electrical and telecommunications industries.
First grade
It means that the raw materials used are leftover materials that are not floored, or they are called undercuts, and some of them are outlet materials, plastic head materials, etc. The quality is also relatively good, that is, they are not used. In the process of processing new materials, the remaining Small corners, or raw materials that are of poor quality. The granules processed from these materials are better in transparency and their quality can be compared with that of new materials. Therefore, they are first-class or special-grade materials.
Secondary material
Means that the raw materials have been used once, but the exception is high-pressure granulation, the use of imported large pieces of high-pressure granulation is mostly, if the imported large pieces of industrial film, is not through the wind and sun, so its quality is also very good, processing The transparency of the particles is good, and it should be judged according to the brightness of the particles and whether the surface is rough.
Three materials
Means that the raw material has been used twice or more, and the processed particles are not very good in all aspects such as elasticity and toughness.
Plastic waste is ubiquitous in life, and its recycling can be made into particles for use in all aspects of life. However, the application fields are different. For example, a convenient bag made of recycled granules cannot be used for packaging of foods, and some granules processed with PVC may contain toxins themselves, so the scope of their application is limited. In general, primary and secondary materials can be used for blown films, drawing, etc., and tertiary materials can generally only be used for injection molding.
