What raw materials are needed to produce carbon black?

There are many types of raw materials for the production of carbon black, such as coal tar, ethylene tar, anthracene oil, natural gas, blast furnace gas, heavy oil, fuel oil, and so on. Some of these raw materials are commonly used for rubber carbon black, and some are used for special carbon black such as pigment carbon black and conductive carbon black. In fact, the most commonly used raw materials for rubber carbon black are coal tar, carbon black oil, blast furnace gas, etc. This is mainly because rubber carbon black has a wide range of uses, and to reduce costs, it is necessary to choose these low-cost raw materials.

What raw material is carbon black produced from? The raw materials for producing carbon black include petroleum products, pitch coal tar, anthracene oil, natural gas, and other raw materials with high carbon content.

1. The carbon black produced from calcium carbide is mostly conductive acetylene carbon black and acetylene conductive carbon black.

2. The carbon black produced from coal tar and anthracene oil is mostly pigment carbon black and rubber carbon black.

3. Carbon black produced from heavy oil mainly includes conductive carbon black, superconducting carbon black, and extra conductive carbon black.

4. Natural gas is mainly used as fuel and can be used to produce carbon black, chemicals, and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry.

5. Anthracene oil, with a high viscosity and solid elution at room temperature, is a raw material for manufacturing coatings, electrodes, pitch coke, carbon black, wood preservative oil, and pesticides. It is mainly used to extract chemical raw materials such as crude anthracene, acenaphthene, fluorene, phenanthrene, and carbazole.

Proportion of raw materials for producing one ton of carbon black: Coal tar is a black viscous liquid that is slightly heavier than water (with a density of 1.17 to 1.17 g/cm3 at 20 ℃). It is a mixture of many organic compounds. Although there are many compounds in coal tar, the content of most compounds is very small. The most important component in coal tar is naphthalene, with an average content of 10%. There are only over 10 compounds with a content of more than 1%. The content of carbon black in coal tar ranges from 54 to 56%, and it takes about 1.8 tons of coal tar to produce one ton of medium temperature carbon black.

Use of rubber carbon black: Rubber carbon black is the most widely used type of carbon black, accounting for over 98% of the total carbon black content. Rubber carbon black is mainly used in the tire industry, and of course, carbon black can also be seen in other rubber products. It can be said that the development of the rubber carbon black industry has witnessed the development of human industry.

Purpose of adding carbon black to rubber: What is the main compensation and filling effect of carbon black added to rubber? Adding a certain amount of carbon black to rubber products can improve the performance of rubber products.

Effect of carbon black on rubber properties: As a reinforcing agent for rubber, carbon black plays an important role in improving modulus, breaking strength, and wear resistance. Carbon black also has an important impact on the melt shear viscosity and tensile viscosity of rubber, thus having an important impact on rubber processing behavior. Moreover, different types of carbon black have different properties, such as specific surface area and structure, and their effects on rubber are also different. Therefore, it is necessary to investigate the impact of carbon black on the tensile properties of rubber.

What is the amount of carbon black added to rubber? The amount of carbon black used in rubber generally accounts for between 20% and 70% of raw rubber, depending on the amount used in different rubber products.

What types of rubber carbon black are available? Rubber carbon black can be divided into several types: high wear resistant, reinforced, and semi reinforced. High wear resistant rubber carbon black models include N110, N220, N330, and N339, reinforced rubber carbon black models include N351, N375, and semi reinforced rubber carbon black models include N550, N660, and N774.
