In the production process of carbon products, the asphalt products produced by our company can react with various carbon materials such as graphite and carbon black to form substances with good cohesiveness, and firmly bond various carbon materials together. Second, because asphalt has good corrosion resistance, it can be used as a preservative for carbon products. Coating a layer of coal pitch on the surface of carbon products can effectively prevent the products from coming into contact with the corrosive medium of the external environment, thereby prolonging the service life of the products. Third, asphalt can be used as a plasticizer for carbon products to improve the plasticity and toughness of products.
