Coal pitch is a by-product of the coal tar processing process and is often used as a road construction, house waterproofing, concrete additive, etc. However, the performance and application fields of coal asphalt are also expanding, among which modified asphalt is an important application direction.
Modified asphalt is obtained by treating coal asphalt at high temperature and high pressure, which has high viscosity, strength and high temperature resistance. In the field of construction, modified asphalt can be used to make waterproof materials, insulation materials, decorative materials, etc., with excellent performance and low cost. In addition, modified asphalt can also be used to make high value-added products such as inks, coatings, and resins, and has a wide range of application prospects.
The properties of modified asphalt mainly depend on the process parameters and the quality of raw materials in its production process. Generally, the softening point, viscosity, strength, high temperature resistance and other aspects of modified asphalt have high performance indicators. In addition, modified asphalt also contains more organic compounds such as aromatic hydrocarbons and phenols, which also have an impact on the properties of asphalt.
In order to better apply modified asphalt, it is necessary to conduct in-depth research and understanding of its properties. The properties of modified asphalt can be studied by experimental testing, chemical analysis, thermal analysis, etc. At the same time, the properties of modified asphalt can also be controlled by adjusting the production process parameters and raw material quality to meet the needs of different fields.
In short, as an important energy and chemical raw material, the application field of coal pitch is constantly expanding. As one of the important application directions of coal asphalt, modified asphalt has a wide range of application prospects and important economic value. In the future, it is also necessary to strengthen the research on its properties and production process to further improve the performance and application range of modified asphalt.
