What are the advantages and challenges of using polyethylene in mining?

The use of polyethylene in the industry, as pipes, equipment and various systems, has its own advantages and challenges. Below are some of the advantages and challenges of using polyethylene in the mining industry:

Advantages:

  • Chemical resistance: Polyethylene shows good resistance to chemicals such as acids, alkalis, sulfuric acid, sodium hydroxide and other chemicals used in minerals. This chemical resistance can be maintained against the effects of water, chemicals present in the soil and other environmental factors.
  • Technical resistance: Ethylene pipes and equipment have high resistance to impact, bending, pressure and other mechanical areas. This feature can significantly improve mining and material transfer.
  • Lightweight and easy portability: Polyethylene offers easy portability compared to metal pipes and equipment due to its lightness and low weight. This can reduce transportation and labor costs.
  • Resistance to rust: Polyethylene is non-rusting and resistant to corrosion. This feature can be useful in mining and in wet and humid conditions.

Challenges:

  • Heat resistance: Polyethylene is less resistant to high heat and can soften or show more plasticity when exposed to high temperatures.
  • Connectivity: To connect polyethylene pipes and equipment, it requires techniques such as heat welding, electrofusion welding and the use of special connections such as coupling connections. This may in some cases require expertise and proper training.
  • Resistance to poly UV rays: Ethylene is sensitive to sunlight and UV rays and may change color and deteriorate under their influence. To deal with this challenge, polyethylene pipes and equipment are available with UV resistant coatings.
  • Size limitation: Polyethylene is used in some cases as smaller pipes and equipment of the smallest size due to the limitation of larger sizes. This can pose a challenge in some larger mining applications and systems.

In general, the use of polyethylene in the mining industry comes with certain advantages and challenges. These materials, according to the technical characteristics and needs of specific projects, should be carefully examined in order to achieve optimization.
