How to choose high-temperature coal tar pitch and an introduction to the uses of high-temperature coal tar pitch

High temperature coal tar pitch softening point (global method), 120-130 ℃ * * insoluble content, 26-34%, quinoline insoluble content, 6-14% β – resin content, ≥ 18%, coking value, ≥ 45%, ash content, ≤ 0.5%, moisture content, ≤ 5%

Modified asphalt is used in the aluminum electrolysis industry to produce pre baked anode blocks, manufacture high-power electrode rods, and can also be used as an electrode binder.

High temperature coal tar pitch can be used for: refractory materials, blast furnace slurry/ramming materials/castables, anhydrous slurry, aluminum electrolysis in aluminum plants, pre baked anode blocks, graphite products: graphite electrodes, graphite blocks, graphite squares, graphite columns, carbon products: electrode paste, anode paste, sealing paste, carbon anodes, cold ramming paste, high-power electrode rods, electrode materials, black metallurgical carbon, electrode carbon brushes, electric carbon products, carbon graphite products, graphite crucibles, graphite large fabrics, carbon black, electric furnace steelmaking electrodes, steelmaking auxiliary materials, blue charcoal, shaped coal, coke, waterproof materials, waterproof coils, waterproof coatings, anti-corrosion coatings, asphalt paint, and then, raw rubber. Needle coke, asphalt coke, activated carbon, magnesia carbon brick, carburizing agent, binder, rubber, carbon material binder, refractory material binder, asphalt based carbon fiber, dry battery sealing material Chemical battery positive electrode materials, high-temperature resistant solid lubricating materials, etc

1.Used as fuel, due to its high solid content, it is generally mixed with heavy oil or made into a slurry for use, which can partially replace heavy oil

2.Used for the production of carbon electrodes. The degree of graphitization of carbon in coal tar pitch is relatively high, and it can be used as electrode material for production, as well as as as as a wetting agent and binder. There are many types of products involved in this area, and it is the main use of coal tar pitch.

3.Coatings, mainly processed and used as waterproof coatings for buildings and pipes. Epoxy coal tar coating is one of the applications.

4.Road construction and building materials are generally mixed with petroleum asphalt. Compared with coal tar asphalt and petroleum asphalt, there is a significant difference in quality and durability. Coal tar asphalt has poor plasticity, poor temperature stability, brittleness in winter, softening in summer, and rapid aging. However, the performance of the mixed asphalt of the two is better than that of their respective individual use. In addition, coal tar pitch has many harmful substances, many of which are very harmful to human health. Only after harmless treatment can it be used more environmentally friendly.

High value-added products such as needle coke, activated carbon, and carbon fiber. Coal tar pitch has a high residual carbon value, multiple graphitic components, and is easy to process. Needle coke and carbon fiber are both good materials with high added value. Using coal tar pitch as raw material is equivalent to turning waste into treasure.
