High-temperature coal pitch is a complex mixture of dark brown to black that is extracted from coal tar through a series of chemical reactions at high temperatures. It has the following properties:
1.Physical properties: High-temperature coal pitch is a thermoplastic material that can form different forms, such as liquid, semi-solid and solid. Its density and viscosity vary depending on temperature and composition.
Chemical composition: High-temperature coal pitch is mainly composed of polycyclic aromatic hydrocarbons, fused aromatic hydrocarbons and heterocyclic compounds, and also contains a small amount of aliphatic hydrocarbons and compounds of sulfur, nitrogen, oxygen and other elements.
3.Adhesion performance: High-temperature coal pitch has excellent adhesion properties, which can bond different materials together to form a stable structure. This characteristic makes it widely used in waterproof, anti-corrosion, wear-resistant coatings in buildings, roads, bridges and other fields.
4.High temperature resistance: High temperature coal pitch has high high temperature resistance and can maintain its stability in high temperature environment. Therefore, it is widely used in high-temperature equipment such as kilns, furnace linings, crucibles and other industries in metallurgy, chemical industry, ceramics and other industries.
Corrosion resistance: High-temperature coal pitch has good corrosion resistance and can resist the erosion of acids, alkalis, salts and other chemicals. Therefore, it has been widely used in the anti-corrosion of pipelines and equipment in petroleum, chemical industry, marine and other fields.
These characteristics make high-temperature coal pitch show excellent performance in many industrial and environmental applications, and have made important contributions to China's industrial development.
