Devulkanisaatio
Devulkanization, also known as devulcanization or desulfurization, is a chemical process used to remove sulfur from vulcanized rubber. This process is essential in the rubber industry to improve the quality and performance of rubber products. Vulcanization is a process that involves heating rubber with sulfur to create a three-dimensional network of polymer chains, which gives rubber its elasticity and durability. However, the addition of sulfur can also introduce impurities and reduce the rubber's physical properties.
The devulkanization process typically involves the use of solvents or chemical reagents to break the sulfur
1. Solvent devulkanization, where a solvent is used to dissolve the rubber and separate it from the
2. Chemical devulkanization, which uses reagents like thiols or amines to react with the sulfur and break
The choice of method depends on the type of rubber and the desired outcome. The process is
Despite its benefits, devulkanization is not without challenges. The process can be energy-intensive and may require
