What Is Abrasion Lining

Industrial abrasion lining is a process used to protect equipment and surfaces from the abrasive wear caused by the movement of solid particles, fluids, or gases. It involves applying a protective layer or lining to the interior surfaces of equipment, such as pipes, chutes, hoppers, tanks, and other machinery that experience significant wear due to the nature of the materials being transported or processed.

The process of industrial abrasion lining typically involves the following steps:

1. Surface Preparation: Before applying the abrasion-resistant lining, the surface of the equipment needs to be properly prepared. This may involve cleaning, degreasing, and sometimes roughening the surface to create a better bonding surface for the lining material.

2. Selection of Lining Material: There are various types of lining materials available, depending on the specific application and the type of abrasion expected. These materials can include rubber, ceramic tiles, polyurethane, high-density plastics, and composite materials. The choice of material depends on factors like the severity of abrasion, chemical resistance, temperature, and other operational conditions.

3. Application of Lining: The selected lining material is then applied to the prepared surface using different methods, including:

   • Spraying: The lining material is sprayed onto the surface using specialized equipment. This is effective for coatings that can be applied as liquid or semi-liquid formulations.

   • Troweling: Some lining materials, like epoxies and mortars, can be troweled onto the surface. This involves manually spreading and smoothing the material over the surface.

   • Tile Installation: In cases where ceramic tiles are used as the abrasion-resistant material, they are adhered to the surface using adhesives. This creates a durable and highly abrasion-resistant surface.

4. Curing and Setting: Once the lining material is applied, it needs to cure or set according to the manufacturer's specifications. This may involve allowing the material to dry and harden, or undergoing a chemical curing process. Proper curing ensures the lining material forms a strong bond with the substrate.

5. Quality Control: After the lining material has cured, it undergoes quality control checks to ensure proper adhesion, uniformity, and coverage. This may involve visual inspections, thickness measurements, and adhesion tests.

6. Final Inspection and Testing: The equipment or surfaces are subjected to various tests and inspections to ensure that the lining material meets the desired performance standards. This can include abrasion tests, impact tests, chemical resistance tests, and more.

7. Maintenance and Monitoring: Even with abrasion-resistant linings in place, regular maintenance and monitoring are essential to detect any signs of wear or damage. If necessary, repairs or reapplications can be carried out to maintain the protective properties of the lining.

Industrial abrasion lining is a crucial process in industries such as mining, manufacturing, chemical processing, and material handling, where equipment and machinery are exposed to harsh abrasive environments. Properly applied and maintained abrasion linings can significantly extend the lifespan of equipment and reduce downtime due to wear-related issues.
