[Chemical Knowledge]：What are the properties, uses, upstream and downstream raw materials, storage methods, properties, uses, upstream and downstream raw materials, and storage methods of carbon black

Carbon black properties

Carbon black is an important inorganic material, the main component is carbon, and its appearance is black powder. Carbon black exhibits excellent adsorption properties due to its very high surface area and rich micropore structure. The electrical conductivity, heat resistance and oxidation resistance of carbon black also make it widely used in many fields. The size and surface area of carbon black particles have a significant impact on its properties. The smaller the particles, the larger the surface area, and the better its reinforcing effect and conductive properties. The chemical purity and surface chemistry (e. g., degree of oxidation) of carbon black also affect its application performance.

Carbon black uses

Carbon black is widely used in the rubber industry, as a reinforcing agent and filler, greatly improving the wear resistance and strength of rubber products, and is an indispensable component in tire manufacturing. In addition, carbon black in plastics, paints, coatings, inks and other fields also have important applications. As a pigment, carbon black has high coloring power and hiding power, and can be used in plastics and inks to give it deep black and good UV resistance. Carbon black also plays an important role in batteries and conductive materials, and its conductivity makes it widely used in lithium-ion batteries, supercapacitors and conductive plastics.

Carbon black upstream feedstock

The raw materials for carbon black production are mainly by-products of oil and natural gas, such as ethylene tar, coal tar and catalytic cracking slurry. These feedstocks undergo pyrolysis or partial combustion to produce carbon black and by-products. The choice of petroleum-based raw materials and coal-based raw materials depends on the production process and product requirements of carbon black. Petroleum-based raw materials are usually used to produce high-quality carbon black due to their high purity and few impurities, while coal-based raw materials are mostly used for the production of general-purpose carbon black due to their low cost.

Carbon black downstream products

The main downstream products of carbon black are rubber products, especially tires. Carbon black is also used in the manufacture of various plastic products, coatings, inks and batteries. In rubber products, the reinforcing effect of carbon black makes it widely used in tires, conveyor belts, seals and anti-vibration pads. In plastic products, carbon black is used as a pigment and anti-ultraviolet agent for the production of pipes, cable sheaths and various plastic containers. In inks and coatings, carbon black provides excellent tinting strength and hiding power, ensuring color stability and durability of prints and coatings. In the field of batteries, the conductivity of carbon black can make it an important part of the conductive agent in lithium batteries and supercapacitors.

Carbon black production process

The furnace method and channel method are mainly used in the production of carbon black. Furnace production is the partial combustion or cracking of raw materials at high temperatures to produce carbon black. This method can produce carbon black with different particle size and structure, with flexible process control, large output and the most widely used. The production of the channel method is a high-temperature cracking of raw materials under limited oxygen conditions to generate carbon black. The carbon black produced by this method has large particles and loose structure and is suitable for some specific applications. There are also special processes such as thermal cracking and gas phase cracking for the production of high-performance carbon black.

Carbon black storage method

Carbon black requires special attention during storage due to its fine particles and high adsorption. Carbon black should be stored in a dry, well-ventilated place, avoid direct sunlight and humid environment to prevent moisture absorption and agglomeration. Carbon black is prone to dust during storage and transportation, and appropriate dust prevention measures should be taken, such as the use of sealed containers and dust bags, to prevent pollution and safety hazards. Carbon black has a certain risk of spontaneous combustion, especially in the case of high dust concentration, so it is necessary to take fire prevention measures during storage and handling to ensure safety.

Carbon black market analysis

The global carbon black market has benefited from the rapid development of the automotive industry and construction industry, especially the growing demand for carbon black in tire manufacturing. The Asia-Pacific region is the market with the largest demand for carbon black, mainly due to the rapid development of automobile and tire manufacturing in countries such as China and India. The North American and European markets also maintained steady growth, benefiting from demand for high-performance rubber and plastic products. With the development of new energy and environmental protection technology, carbon black has broad application prospects in the field of batteries and conductive materials, and will become an important driving force for future market growth. Carbon black production enterprises are facing the challenge of raw material price fluctuations and increasingly stringent environmental regulations, and need to continuously improve production technology and management level to cope with market changes.

Carbon black industry challenges and opportunities
