There are many factors that affect the viscosity of coal pitch, including temperature, quality and additives. As the temperature increases, the viscosity of the coal pitch decreases, which is due to the fact that the force inside the coal pitch molecules is weakened as the temperature increases. The **, composition, and quality of coal pitch will also have an impact on its viscosity, for example, the composition and structure of coal pitch of different coal types will be different, resulting in the performance of different viscosities. In addition, in order to improve the performance of coal asphalt, various main agents are often added in the production process, such as plasticizers, antioxidants, viscosity reducers, etc., and these additives will also have a certain impact on the viscosity of coal asphalt.
The viscosity of coal pitch is related to the plasticity of asphalt, which varies with temperature and is extremely sensitive to temperature reactions. In the production process, the relationship between the softening point and the viscosity can be used to estimate the relative magnitude of the viscosity of coal pitch. In actual production, the softening point is often compared with the viscosity, but the relative magnitude of the viscosity of coal pitch can only be seen from the softening temperature.
In addition, asphalt materials with different viscosities have different performance properties. The more viscous asphalt material, the worse its fluidity and the more difficult it is to be compacted or form a structure, so it is necessary to choose the appropriate viscosity to adapt to different use needs. In road construction and maintenance, the viscosity of asphalt needs to be strictly controlled to ensure its performance and life.
The viscosity of coal pitch has an important impact on its performance and production process, and it is necessary to strictly control the **, composition, quality and additives of coal pitch in the production process to ensure that the coal asphalt products with appropriate viscosity are obtained.
