Coal asphalt Medium temperature asphalt solid + liquid.
Medium-temperature coal pitch liquid is an important product in the process of coal tar distillation, and its softening point is between 80-180. This liquid has a black or dark brown viscous shape and has a high specific gravity and viscosity.
Its main components are polymer aromatic hydrocarbons and their derivatives, and contain a small amount of aliphatic hydrocarbons, naphthenes and heterocyclic compounds containing oxygen, nitrogen and sulfur.
Medium temperature coal pitch liquid has a variety of excellent physical and chemical properties, such as good adhesion, wettability, chemical stability, heat resistance, oxidation resistance and electrical insulation. These characteristics make it widely used in many fields.
In the coatings and paints industry, it can be used as a raw material for anti-corrosion coatings, waterproofing coatings and road marking paints to protect substrates from corrosion and damage.
In the field of rubber and plastics, medium-temperature coal asphalt liquid can be used as a plasticizer, filler and anti-aging agent to improve the toughness, aging resistance and chemical resistance of rubber and plastics.
In addition, it also plays an important role in graphite electrode manufacturing, the casting industry, and the production of electrode paste, waterproof materials, anti-corrosion materials, etc.
The process of producing medium-temperature coal bitumen liquids typically includes steps such as coal tar distillation, residue separation, and refining treatment. These process controls have a significant impact on the quality and performance of coal pitch.
With the continuous progress of science and technology, the application field of medium-temperature coal asphalt liquid will continue to expand, and it will play an increasingly important role in the development of related industries. At the same time, attention should also be paid to exploring more environmentally friendly and efficient alternatives to meet the growing demand for environmental protection.
