There are some differences between coal pitch and high-temperature pitch in composition and properties.
First of all, they differ in their composition. Coal pitch is mainly composed of aromatic compounds above tricyclic and nitrogen-containing, oxygen-containing and sulfur-containing heterocyclic compounds, as well as a small amount of polymer carbon substances. High-temperature asphalt, on the other hand, is mainly composed of low-molecular weight hydrocarbons and aromatic hydrocarbons, and its molecular weight distribution is relatively narrow. These different chemistries make them also different in terms of physical properties and applications.
Secondly, there are also differences in the properties of coal pitch and high-temperature asphalt. Coal pitch has a high viscosity and viscosity, and appears as a black or brown viscous liquid, with a harder texture and a darker color. Whereas, high-temperature asphalt shows good thermal and chemical stability at high temperatures.
In addition, due to the different production processes and production processes of coal pitch and high-temperature asphalt, there are certain differences in their uses. Coal asphalt is mainly used in the preparation of building materials, waterproof materials and other fields, while high-temperature asphalt may have a wider range of uses, including road construction, anti-corrosion, coatings and other fields.
It should be noted that the specific composition and properties of coal pitch and high-temperature asphalt may vary depending on the production process and raw materials. Therefore, in practical applications, it is necessary to select suitable asphalt materials according to specific needs and refer to relevant technical specifications and standards for use.
