What is Vulcanising?

Vulcanising is the process of curing elastomers (rubber) to improve their strength, durability, and elasticity. It involves creating chemical cross-links between rubber molecules, transforming it from a soft, malleable material to one that retains its shape and can withstand stress, heat, and abrasion.?

What is Cold Vulcanising?

Cold vulcanising is a method of splicing or repairing rubber and conveyor belts using a specialised adhesive or bonding agent that cures at room temperature without the need for heat. It is ideal for quick on-site repairs or situations where heat application is impractical. While not as durable as hot vulcanising, it is effective for minor repairs and less demanding applications.

What is Hot Vulcanising?

Hot vulcanising involves applying heat and pressure to bond rubber surfaces chemically. This method creates a seamless and durable splice, ideal for heavy-duty conveyor belts that require maximum strength and longevity. Although more time-consuming and specialised, it is preferred for critical applications in the mining, construction, and manufacturing industries.

What are the Different Methods of Vulcanising?

The main methods of vulcanising are:

1. Hot Vulcanising: Uses heat and pressure to bond rubber components.
2. Cold Vulcanising: Relies on adhesive that cures at room temperature.
3. Mechanically Clipped Joint: Uses mechanical fasteners to join belt ends without heat or adhesives.
4. Super Screw Joint: Combines mechanical fastening and vulcanisation for a durable, flexible splice.

Additionally, vulcanisation can be performed as:

Open Vulcanisation: Curing rubber in ovens or autoclaves.

Continuous Vulcanisation: A single-line operation where rubber continuously passes through heated tunnels for curing.

Where Does Vulcanising Come From?

The concept of vulcanisation originated with ancient Mesoamerican cultures, which cured rubber using sulphur-rich plant juices. Charles Goodyear invented modern vulcanisation in 1839 when he accidentally dropped a sulphur-rubber mixture onto a hot pan. He discovered that heat hardened the rubber, and he patented the process in 1844, revolutionising the rubber industry.
