vulcanisation
Definition
Noun: - A chemical process, specifically for rubber or similar materials, involving treatment with sulfur (or other curatives) under heat and pressure. This process creates cross-links between polymer chains, fundamentally altering the material's properties by increasing its elasticity, strength, durability, and resistance to temperature changes and solvents.
Usage
- As a subject: Describes the process itself.
- Vulcanisation transforms soft, sticky natural rubber into a durable material suitable for tires.
- The discovery of vulcanisation revolutionized the rubber industry.
- As an object: Describes something undergoing the process.
- The compound requires vulcanisation to achieve its final properties.
- They accelerated production by optimizing the vulcanisation time.
Advanced Usage
- Technical Contexts: The term is standard in materials science, polymer chemistry, and industrial manufacturing.
- The study compared the efficiency of different accelerators used in the vulcanisation process.
- Vulcanisation kinetics are critical for determining the optimal cure cycle.
Variants and Related Words
- Vulcanize (verb): To subject a material to the vulcanisation process.
- They vulcanize the rubber to make it more resilient.
- Vulcanized (adjective): Describing a material that has undergone vulcanisation.
- Vulcanized rubber is used in shoe soles and hoses.
- Cure/Curing (noun/verb): A common synonym in industrial contexts for the vulcanisation process.
- The rubber parts are placed in a press for curing.
Synonyms
- Curing: The process of hardening a polymer material through chemical reactions, often used interchangeably with vulcanisation for rubber.
- Cross-linking: A more general chemical term for the formation of bonds between polymer chains, which is the essential result of vulcanisation.
Related Phrases/Compounds
- Vulcanisation agent: A substance, like sulfur, that causes the cross-linking reaction.
- Vulcanisation accelerator: A chemical additive used to speed up the vulcanisation process.
- Post-vulcanisation: Any treatment or property change that occurs after the main vulcanisation process is complete.
Noun
-
process of treating rubber or rubberlike materials with sulphur at great heat to improve elasticity and strength or to harden them
