Carbon Black
Carbon black is a solid material that is using a wide range of applications. It is typically used as coloring and a reinforcing filler in rubber products, such as tires and pads. Carbon black is composed primarily of elemental carbon, and is produced by incomplete combustion of petroleum and gas. The particle size of carbon black ranges from 10 to 500 nanometers in diameter. Carbon black is a particular form of elemental carbon that has lost its absorption ability, meaning particles cannot absorb molecules. Carbon black has an extremely high surface area and an oxidizing atmosphere.
Carbon black is attractive to many industries due to its low cost, physical and chemical properties. Its uses range from dulling colors to blackening surfaces and from extending the life of materials to power conversion. One of its main uses is as a pigment. The color, intensity and tinting strength of carbon black depends on the source, particle size and method of milling. It is less expensive than other colors, plus the colors produced by carbon black are intense and resistant to fading.
In rubber products, carbon black has some unique properties. It improves the rubbers physical characteristics and weather resistance, while also contributing to the products cost reduction. By providing a space filler and improving rubber hardness, carbon black also helps to reduce rolling resistance and enhance fuel economy.
Carbon black has a very high surface area, meaning it has an enormous capacity for absorbing pollutants. Carbon black has been used as a filter material due to its high adsorptive ability. It has been used to purify drinking water, to remove organic and particulate compounds from wastewater, and to remove various compounds from industrial waste streams.
Carbon black is also used in many industrial processes. It is used in complexes for carbonizing, where carbon black particles react with gaseous substances to form solid materials. Carbon black is also used to improve strength and dimensional stability in various manufacturing processes.
Finally, carbon black is used for thermal insulation and for other insulation purposes. Carbon black is also used to protect certain materials from electrical discharges and high temperatures. Carbon black can also be used in textiles, plastics and pharmaceuticals as a principal ingredient in these products.
Overall, carbon black is a versatile material that is often used in a wide variety of applications. Its resistance to fading, low cost, easy coloring and reinforcing properties make it a unique choice for many industries. It also has a great adsorptive ability, which makes it a great choice for filtration and insulation purposes. Carbon black is truly an indispensable material.
