The ash content of coal pitch represents the inorganic content of coal pitch. Ash refers to the residue of coal pitch after high temperature combustion, and is the content index of inorganic matter in coal asphalt. Coal pitch with high ash content has a high content of inorganic substances, and coal asphalt with low ash content has a low content of inorganic substances.
Coal pitch is an important petrochemical raw material, which is widely used in road construction, waterproof materials, coatings and other fields. Ash is an important quality indicator when producing and using coal pitch. If the ash content of coal pitch is too high, it will lead to an increase in its hardness, affecting its processing and application performance. At the same time, coal pitch with high ash content may also contain more impurities and harmful substances, which affects its safety.
Therefore, for the production and use of coal pitch, it is very important to control its ash content. Generally speaking, the ash content of coal pitch is controlled at a low level to ensure its good processing and application performance. At the same time, when using coal asphalt, it is also necessary to carry out a reasonable ratio and use according to its ash content to avoid adverse effects.
In short, the ash content of coal pitch represents the content of inorganic substances in it, which is one of the important indicators to measure the quality of coal asphalt. For enterprises that produce and use coal asphalt, it is very important to control the ash content of coal asphalt.
