What is oil absorption number?
What is oil absorption number?
Oil absorption number (OAN) is a measure of the ability of a carbon black to absorb liquids. This property is a function of the structure of the carbon black. The same method is used for the determination of the oil absorption number of compressed samples of carbon black.
What country does carbon black come from?
the United States
History of carbon black In the 1740’s, plant production started in the United States, and because of the production method used, it was then called “lampblack.” The term “carbon black” originated in the 1870’s, when products manufactured from natural gas were sold under this name. And since then the name prevails.
Who is the largest producer of black carbon?
China is a major contributor to the production of black carbon. China is also the world’s largest exporter of black carbon. This dominance of China in the carbon black production and export has made the Asia pacific to be the major region in the carbon black market.
How is carbon black shipped?
Carbon black is transported mainly in railroad hopper cars, with some shipments in hopper trucks, he said. We wish our customers were faster in returning them, or the railroad companies faster in getting the product to customers.” Hopper cars cost $100,000 apiece, and payback isn’t very fast, Horning said.
What is DBP absorption?
The test method was originally named Dibutyl Phthalate Absorption Number of Carbon Black and is still known as “DBP”. The specific structure parameter cited as most important in determining relationships to compound properties is carbon black intra- aggregate void volume, often referred to as primary structure.
Is black dust harmful?
Inhaling carbon black particles can irritate the lungs and cause coughing. Carbon black can also irritate the eyes, nose and throat. When people are exposed to high levels of carbon black over many years, the particles may lodge deep in their lungs.
What is the future of carbon black?
The global carbon black market was valued at $17.5 billion in 2018, and is projected to reach $23.0 billion by 2026, growing at a CAGR of 3.5% from 2019 to 2026.
Who is the manufacturer of carbon black?
Major carbon black manufacturers operating in India include Phillips Carbon Black Limited, SKI Carbon, Continental Carbon India, Cabot India, and Himadri Chemicals and Industries Limited.
What Colour is carbon black?
Carbon black (Color Index International, PBK-7) is the name of a common black pigment, traditionally produced from charring organic materials such as wood or bone. It appears black because it reflects very little light in the visible part of the spectrum, with an albedo near zero.
What is the difference between carbon black and activated carbon?
The key difference between carbon black and activated carbon is that the surface-area-to-volume ratio of carbon black is lower than that of activated carbon. Besides, carbon black is produced from incomplete combustion of heavy petroleum products while activated carbon is produced from charcoal.
What is DBP carbon black?
The test method was originally named Dibutyl Phthalate Absorption Number of Carbon Black and is still known as “DBP”. Intra-aggregate void volume for a mass of carbon black represents the volume in which a polymer can occlude, thereby resulting in a shift in effective filler volume fraction.
What is the absorption number of carbon black?
Active Standard ASTM D2414 | Developed by Subcommittee: D24.11 Book of Standards Volume: 09.01 4.1 The oil absorption number of a carbon black is related to the processing and vulcanizate properties of rubber compounds containing the carbon black.
What is the purpose of the oil absorption number?
The oil absorption number is widely used for characterizing the structure of carbon blacks and other free flowing materials which has a strong effect on the processing and vulcanization parameters and the quality of the product as well. How does this instrument work?
How is carbon black produced in the world?
This process is the most widely used in the world comprising over 98% of all carbon black production, because it permits the to influence and control the main carbon black properties like specifically engineered aggregates of carbon particles that vary in particle size, aggregate size, shape, porosity and surface chemistry.
What kind of coal tar is used for carbon black?
Main coal tar distillate for carbon black production is for example anthracene oil. Both groups have a high content of aromatic hydrocarbons in common. Further feedstocks are heavy petroleum fraction, distillation residues form oil refineries, and different oil mixtures. Further can be used natural gas, naphtha, gas oil and acetylene.
