Rubber Coating of Drive and Reversal Drums and Rollers

What is Drum Rubber Coating?

At Power Rubber, we offer the service of rubber coating for reversible and drive drums. This involves applying a protective coating to various machine components exposed to mechanical damage or chemical substances.

Drum Coating Methods

We can use one of two vulcanization methods for coating drums: cold vulcanization or hot vulcanization.

Cold Vulcanization

Cold vulcanization, also known as cladding, involves first applying a strong adhesive to the drum surface, followed by the attachment of a rubber lining. The resulting surface can be smooth, ceramic, or patterned with a checkerboard design.

Hot Vulcanization

The hot vulcanization process requires the drum to be thoroughly cleaned first. Then, a layer of hot, liquid rubber is applied, which adheres perfectly to the surface. After curing, the surface remains flat or can be patterned with a checkerboard design.

Roller Coating - Technique and Applications

Roller coating involves covering metal components (the roller core) with rubber material. This reduces wear and tear on conveyor belts.

Technique and Process of Rubber Coating

Preparing the Core and Bonding Rubber to Metal

At this stage, anti-corrosion materials are removed using steam at 150°C, followed by sandblasting and solvent cleaning to remove oil and grease residues.

Creating the Rubber Coating

In the mixing process, special fillers, plasticizers, stabilizers, and vulcanizing agents are added to modify the physical and chemical properties of the mixture.

Gluing

This process involves applying a chemical bonding agent or an ebonite base layer to the metal core, followed by rubber coating.

Vulcanization and Cooling

After vulcanization, the rubber becomes more stable and resistant to heat, cold, and solvents. It is then hardened and cooled.

Rubber Coating of Drive and Reversal Drums

Professional rubber coating of drive and reversal drums protects the structure from mechanical impacts.

Applications of Rubber Coated Drums

Rubber-coated drums are widely used in industries such as food processing, automotive, transportation, and manufacturing to improve durability and reduce noise.
