High-temperature bitumen 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 unique physical and chemical properties and is widely used in industrial and environmental fields.
The main components of high-temperature asphalt include polycyclic aromatic hydrocarbons, fused aromatic hydrocarbons and heterocyclic compounds, and also contain a small amount of aliphatic hydrocarbons and compounds of sulfur, nitrogen, oxygen and other elements. Its physical properties are thermoplastic materials that can be formed in different forms, such as liquid, semi-solid, and solid. Density and viscosity vary depending on temperature and composition.
High-temperature asphalt has a wide range of applications, including as an electrode binder, briquette binder, in the production of asphalt coke, in the manufacture of asphalt varnish, etc. It has applications in construction, transportation, water conservancy, petroleum, chemical industry and other fields. The softening point of high-temperature asphalt is one of the key indicators to divide its type, and high-temperature asphalt with different softening points has different properties and application fields.
Overall, high-temperature asphalt has shown excellent performance in many industrial and environmental applications with its unique physical and chemical properties, and has made important contributions to China's industrial development.
