Characteristics of Rubber Grinding Stones
Definition of Rubber
Rubber is a material that exhibits elastic deformation.
Elastic deformation: the property of stretching or compressing significantly in the direction of applied force and returning to its original shape when the force is removed.
Molecular chains are entangled with one another.
Mechanism of Elastic Deformation in Rubber
- Rubber consists of long, flexible chains called polymer chains
- The polymer chains are entangled with each other, forming spherical coils (random coils)
- These coils deform under small forces and return to their original shape when the force is removed
Mechanism of Strength Enhancement in Rubber
Types of Raw Rubber
Raw Rubber
Natural Rubber
A product obtained by drying and solidifying the latex secreted by several types of rubber trees
- Excellent mechanical properties
- A natural material that protects the global environment
Synthetic Rubber
A product with a chemical structure obtained industrially from petroleum
- Rubber with a variety of properties
The usage amounts of natural and synthetic rubber are roughly equal.
