Coal asphalt manufacturer Shenlu I. Overview of coal asphalt Coal asphalt, also known as coal tar asphalt, is a black solid substance obtained from coal tar after distillation, oxidation, extraction and other processes. It is a by-product produced in the process of coal processing, and is widely used in waterproof materials, anti-corrosion materials, electrode materials and other fields. 2. The composition of coal asphalt Coal asphalt is mainly composed of a variety of organic compounds, including polycyclic aromatic hydrocarbons, phenols, naphthalene, quinolines, etc. These compounds have different chemical and physical properties, which give coal pitch unique properties and uses. 3. The properties of coal pitch Physical properties: Coal pitch has a black solid, greasy feeling, is not easy to dissolve in water, and is easily soluble in organic solvents. Chemical properties: Coal pitch has certain chemical stability, corrosion resistance and oxidation resistance. It is easy to oxidize at high temperatures, producing smoke and harmful gases. Fourth, the use of coal asphalt waterproof materials: coal asphalt has good waterproof performance, can be used to make waterproof materials, such as waterproof membrane, waterproof coatings, etc. Anticorrosive materials: Due to the corrosion resistance of coal asphalt, it can be used to make anticorrosive materials, such as anticorrosive coatings, preservatives, etc. Electrode material: Coal pitch has good conductivity and can be used to make electrode materials, such as electrocarbon electrodes, electrode plates, etc. Other uses: Coal pitch can also be used to make energy products such as fuel oil and fuel gas, as well as as a chemical raw material to produce various chemicals.
Fifth, the production process of coal asphalt.
The production process of coal asphalt mainly includes distillation, oxidation, extraction and other steps. Firstly, the coal tar is distilled to separate various components, and then the obtained components are oxidized to form new compounds by oxidation reaction of organic compounds such as polycyclic aromatic hydrocarbons, and finally the coal asphalt products are obtained by extraction and other methods.
6. Storage and transportation of coal asphalt.
Storage: Coal pitch should be stored in a cool and dry place, away from direct sunlight and high temperature environments. At the same time, it is necessary to prevent contact with strong oxidants, so as not to cause chemical reactions.
Transportation: Prevent collision and friction during transportation to avoid damage to the packaging and products. At the same time, it is necessary to avoid mixing with dangerous goods such as strong oxidants.
7. Safe use of coal asphalt.
When using coal asphalt, pay attention to safety protection measures, such as wearing masks, gloves and other protective equipment. Avoid prolonged exposure** and inhalation of its fumes. During storage and transportation, it is necessary to prevent leakage and environmental pollution. In case of leakage, clean up and dispose of waste properly. It is necessary to strictly abide by the relevant regulations and operating procedures to ensure safe use. If there is an abnormal situation, it should be stopped immediately and reported to the relevant departments for treatment in time.
8. Summary. As an important chemical raw material and fuel oil product, coal pitch plays an important role in production and life. It is of great significance to understand and master the knowledge of the nature, use, production process, storage and transportation of coal asphalt for the correct use and maintenance of its safety. At the same time, in actual production and life, it is necessary to pay attention to the safe use and maintenance of its safety, so as to ensure the safety of people's lives and property and the stable development of society.
