Chinese name: high temperature asphalt Alias: hard asphalt.
Softening point: 95 120 Method: Heat transfer oil, hot water, steam.
It can process high-temperature asphalt powder 80-100 mesh 0-3mm
Warm asphalt powder, the product has the characteristics of fixed carbon, high content of toluene insoluble resin, low ash content and so on.
High-temperature asphalt is the residual part of coal tar distillation, the yield accounts for 54 56% of tar, it is composed of more than three rings of aromatic compounds and oxygen, nitrogen, sulfur-containing heterocyclic compounds and a small amount of polymer carbon substances. High-temperature asphalt is a black solid at room temperature, and the physical and chemical properties of high-temperature asphalt are related to the properties of the original coal tar and its distillation conditions. The molecular weight of the bitumen component is between 200 and 2000 and can reach up to 3000. The high-temperature asphalt of Jinshi refractory is divided according to the different softening points. A softening point of 120 is called high-temperature asphalt.
Widely used; The additives of blast furnace iron trench material, blast furnace gunning material, ramming material and castable material, amorphous refractory material and carbon material can play a role in bonding and carburizing, and improve the high temperature resistance and erosion resistance of product A.
Solubility of high-temperature asphalt powder.
High-temperature asphalt powder is a hydrophobic material, which is impermeable to water and almost insoluble in water. Acetone, ether, dilute ethanol, soluble in carbon disulfide, carbon tetrachloride, sodium hydroxide.
High-temperature asphalt is used to make linoleum, building waterproof layer, high-grade asphalt paint, activated carbon refractory, carbon products, metallurgy and other industries, and is also a raw material for making asphalt coke or delayed coke and modified asphalt.
