Coal Tar Pitch is the main product of our company.The softening point of medium temperature pitch is 85-95, which is used for carbon products, such as graphite electrode, electrode paste, activated carbon, asphalt paint, needle coke, etc. The modified asphalt has a softening point of 108-115, which is mainly used in the production of pre baked anode block in electrolytic aluminum industry, the manufacture of graphite electrode, fine structure graphite, gun mud, refractory and other binders, as well as the coating agent of lithium battery anode material.
Naphthalene is mainly used in the production of phthalic anhydride, dyes, resins, 2-naphthol, refined naphthalene and camphor pills; it can also be used in the production of water reducing agent, dispersant, synthetic resin, plasticizer, rubber antioxidant, surfactant, synthetic fiber, medicine and perfume, etc.
Creosote oil was prepared from coal tar by distillation at 200-400 ℃. The naphthalene, anthracene and other crystals in the distillate were removed, and then the water-soluble phenol and pyridine were separated. It is used as raw material of carbon black for automobile tire, rubber and printer toner. It is used as preservative for all kinds of wood of sleeper, electric pole and outdoor building materials.
Graphite Electrode is used as conductive electrode in electric arc steelmaking furnace and refining furnace; it is also used in industrial silicon furnace, yellow phosphorus furnace and corundum furnace as conductive electrode.
