When metal equipment parts wear out quickly, it leads to frequent downtime and increased maintenance costs. Using polyurethane with its exceptional wear resistance can significantly extend the lifespan of such components. In this article, we explore how polyurethane lining can solve these issues and the advantages it offers.
What is Polyurethane Lining?
Polyurethane lining is the process of applying a polyurethane coating to surfaces of parts that undergo intensive wear. This solution is suitable for a variety of equipment in industries such as mining, metallurgy, and many others. Polyurethane has wear resistance that is 10 times greater than rubber, making it an ideal choice for lining.
The lining is applied using the free casting method, which allows for precise reproduction of the part’s shape and ensures a tight fit. For example, elevator buckets or shafts receive additional protection against abrasive wear and mechanical damage. Installation of such elements is carried out using special fasteners or adhesive primers, which enhance the reliability of adhesion.
Advantages of Polyurethane Lining
Polyurethane extends the lifespan of parts due to its mechanical properties. It has a wide working temperature range from -60 to +100 °C, allowing its use in various conditions. Additionally, polyurethane has high resistance to chemicals and abrasive materials, making it a versatile material for different industries.
Equipment with polyurethane lining requires less maintenance because the material is resistant to corrosion and chemical reactions. This reduces the costs of part replacement and production downtime. For example, concrete mixer scrapers coated with polyurethane maintain their efficiency much longer compared to traditional materials.
How to Choose the Right Hardness of Polyurethane?
Choosing the hardness of polyurethane depends on specific operating conditions. For parts subjected to high mechanical loads, a material with hardness closer to 70 Shore D should be selected. For less loaded components, softer polyurethane of 50 Shore A is suitable.
| Parameter | Polyurethane | Rubber |
|---|---|---|
| Wear Resistance | 10 times higher | Lower |
| Working Temperature | -60 to +100 °C | Limited |
| Repairability | High | Medium |
| Weight | Light | Medium |
Important factors in the selection also include the type of load: static or dynamic. For static loads, where strength is crucial, a harder polyurethane is recommended. For dynamic loads, a more elastic one is preferred to compensate for vibrations.
Applications of Lining in Various Industries
Polyurethane lining is widely used in industries such as mechanical engineering, oil and gas, food processing, and more. For example, in the mining industry, polyurethane is used for lining screens and grizzly parts that are constantly subjected to abrasive wear. The TIMOL polyurethane products catalog offers a wide selection of such products.
In the metallurgical industry, lining shafts with polyurethane reduces the risk of damage from high temperatures and chemicals. In the food industry, polyurethane coating prevents product contamination and facilitates equipment cleaning.
