LDPE waste: processing and use
With polyethylene, a person is almosteveryday. LDPE waste is also accumulated in enterprises. After using the products, they can be discarded, destroyed, but this is considered an irrational solution. The material disintegrates long enough. Unnecessary items can be taken, getting money for it. After admission, companies process raw materials with further receipt of new products for everyday use.
Recycling
Thanks to modern technologies, LDPE wasteserve for processing. After that, the raw material is not inferior in properties to the primary material. Processing is carried out due to the transformation of materials into granules. The procedure includes several stages:
- Collection.
- Sorting.
- Cleaning.
- Agglomeration.
- Secondary cleaning and drying.
- Granulation.
Only with the implementation of these actions willto create high-quality products. Each stage in the enterprise is controlled by specialists. After processing, raw materials can be used to produce new products or serve in the manufacture of materials similar to primary materials. Reception of LDPE waste is carried out by private companies that are engaged in their processing. Thanks to this procedure, the environment is protected from the harmful effects of waste products.
Sorting
It is important that the waste of the LDPE film is homogeneous. The efficiency of processing depends on sunlight, chemical reagents, moisture, traces of exploitation. To materials with different characteristics a different technological approach is used.
Waste is packaging bags, coloredfilms and other materials. As a result of processing, the same products are usually obtained. It is assumed that due to the short life of the material, the material was not influenced by negative factors, so it could not change its properties.
But there is a waste of LDPE with a modified structure. Then they are suitable for obtaining solid materials due to mixing with additional substances, for example, with sawdust. And only in rare cases they are used in pure form. This polyethylene is processed by agglomeration, that is, the breakdown of the product into polymers. Such material is used for agricultural needs, making buckets, barrels, other products.
Application of secondary LDPE
The LDPE waste, which was recycled,are used for making plastic. The cost of such material will be lower. Secondary LDPE is more profitable for the industry, manufacturing containers for special chemical components, household films.
A promising direction is considered to be manufacturingproducts with the use of fillers and additives. Also in their composition can be composite materials, replacing wood and metals. Their combination allows you to receive a variety of products.
Many organizations perform processing of raw materials,so they need unnecessary polyethylene. Some of them work with processing industries. This makes it possible to utilize waste, and also to receive a good income. In addition, such products are not harmful to nature.
LDPE properties
The main property of PVD products is strength. And it remains after processing. Also, the finished product has other characteristics:
- flexibility;
- elasticity;
- resistance to chemical components;
- resistance to temperatures and ultraviolet.
After processing, waste is used for manufacturingbottles, containers, containers, packaging film, liners, coils. Raw materials are used in the production of fillers for electrical equipment elements, as well as for the production of garden plastic furniture.
Recycle garbage is necessary, becauseproduction of these products has low costs. To have excellent results, careful sorting is necessary. It should be borne in mind that the price of raw materials is determined by purity and quality. Therefore, only the best products are used for processing, because it takes less time and costs.
