It is one of the vital components in manufacturing many products that we use everyday.
Carbon black in its pure form is a fine black powder formed mainly from carbon.
It is produced by partial burning and thermal decomposition, of cheap residues of petroleum products, in high temperature and the whole process under high supervision.
Carbon black is mainly used in strengthening rubber tires, pigment, UV stabilizer and as a conductor or an insulator in several types of rubber, plastic, inks and paints applications, and as well as manufacturing hoses and conveyor belts.
The basic properties of carbon black:
1- Particle size
It is measured by electronic microscope. It is the basic property that has significant impact on rubber properties, in addition of color property of carbon black. As for advanced carbon black, the smaller particles diameter increases the surface area that strengthening the tint. As for rubber, the micro particles increases reinforcement, corrosion resistance, and tensile strength.
This is a basic property for carbon black that can be controlled during production process. This property affects the surface area, providing a total surface area (NSA) greater than the external surface area (STSA).
3- Surface chemistry
The oxidizing surfaces of carbon black are characterised by improving, moisturizing, and fixing pigments. Oxidation increases chemical resistance and makes the carbon color more water resisting.
This is important in matching carbon black with equipment used. The physical form (powder or granules) can affect the way of handling and mixing.
