Brief Introduction
Coal tar is a complex mixture of highly aromatic hydrocarbons, most of which are polycyclic and fused ring compounds with or without side chains and heterocyclic compounds containing oxygen, sulfur and nitrogen, and contain a small amount of fatty hydrocarbons, cycloalkanes and unsaturated hydrocarbons, as well as coal dust, coke dust and pyrolytic carbon. The newly recovered coal tar also contains about 5% water dissolved with a variety of inorganic salts and other impurities. Due to the existence of pyrolytic carbon with very fine particles, water often forms a stable emulsion with oil. Most components of coal tar have high melting points, but due to the mutual dissolution of a large number of monomer compounds to form a low CO soluble mixture, coal tar is still in a liquid state at room temperature.
Brief Introduction
Gypsum retarders are divided into proteins and modified amino acids according to chemical components. Among them, protein gypsum retarder has the characteristics of good retarding effect, small dosage and strong alkali resistance. It is mainly applicable to plastering gypsum, bonding gypsum, gypsum putty, gypsum based self leveling mortar, gypsum decorative line mortar, prefabricated gypsum components, gypsum joint filler, mold gypsum, gypsum finishing coating and other fields.
