First, the production of high-temperature asphalt.
High-temperature bitumen is made from coal tar through a series of processes. First, the coal tar is distilled at high temperature to separate various components, including light oil, phenol oil, naphthalene oil, washing oil and anthracene oil. These components are then further processed through different processes to produce high-temperature bitumen.
In the production process of high-temperature asphalt, process parameters such as temperature and pressure need to be strictly controlled to ensure product quality and stability. At the same time, it is also necessary to take corresponding environmental protection measures to reduce environmental pollution in the production process.
Second, the properties of high-temperature asphalt.
High-temperature bitumen is a black or dark brown viscous liquid with a peculiar odor and toxicity. It has a greater viscosity and is insoluble in water but can be soluble in some organic solvents. The chemical properties of high-temperature asphalt are relatively stable and not easy to react with other substances. 
The softening point of high-temperature asphalt is high, generally above 100. It also has a high flash point and is not flammable. These properties make high-temperature asphalt have good stability and durability in high-temperature environments.
3. The use of high-temperature asphalt.
Due to its good stability and durability, high-temperature asphalt has a wide range of applications in many fields. The following are the main uses of high-temperature asphalt:
1.Road construction materials: High-temperature asphalt is one of the main materials for the construction of large-scale infrastructure such as highways, bridges and airports. It is able to withstand large loads and friction, and has good anti-rutting and anti-slip properties. Therefore, it is widely used in road construction.
2.Anticorrosive material: Due to the good chemical stability and corrosion resistance of high-temperature asphalt, it can be used as an anticorrosive material. For example, in areas such as pipelines, storage tanks and chemical plants, high-temperature asphalt can be used as an anti-corrosion coating to effectively prevent metal corrosion.
3.Binders: High-temperature bitumen can be used as a binder to bond different materials together. For example, in the fields of furniture, building renovation and vehicle maintenance, high-temperature asphalt can be used as a binder to connect different materials quickly and easily.
4.Waterproofing material: High-temperature asphalt has good waterproof properties and can be used as a waterproofing material for buildings. For example, in areas such as roofs, basements and toilets, high-temperature asphalt can be used as a waterproof coating to effectively prevent moisture penetration.
5.Other uses: In addition to the above uses, high-temperature asphalt can also be used to make some other products, such as: making mulch film, producing antiseptic wood, etc.
Fourth, the market prospects.
With the continuous development of infrastructure construction and industrial production, the demand for high-temperature asphalt is also increasing. At the same time, due to the improvement of environmental protection requirements and the shortage of energy, the production process and technology of high-temperature asphalt are also constantly improved and upgraded. Therefore, the high-temperature asphalt market has broad prospects and great development potential.
To sum up, as an important industrial raw material, the production and application of high-temperature asphalt has a wide range of market prospects and social value. In the future, with the advancement of technology and the expansion of application fields, the application prospect of high-temperature asphalt will be broader.
