The use and explanation of high-temperature coal pitch.
High-temperature coal pitch, also known as tar pitch, is a material processed from coal tar. Due to its unique physical and chemical properties, high-temperature coal pitch has a wide range of applications in many fields. This article will introduce the uses of high-temperature coal asphalt in detail, as well as the precautions in its production, processing and use. 
First, the use of high-temperature coal asphalt.
1.Road construction materials.
High-temperature coal pitch is a good road construction material, especially suitable for highways, airport runways and other occasions with high durability requirements. Because it has good wear, pressure and water resistance, it can effectively improve the service life of the pavement. During the construction process, high-temperature coal asphalt can be mixed with other materials to make asphalt concrete, which further improves the quality of the pavement.
2.Waterproof material.
Because high-temperature coal pitch has good waterproof properties, it is widely used as a waterproofing material for buildings. By coating the surface of the building with high-temperature coal pitch, it can effectively prevent moisture penetration and protect the building from moisture and corrosion. 
3.Anticorrosive materials.
High-temperature coal pitch can also be used as an anti-corrosion material, especially suitable for the anti-corrosion treatment of metal products. By coating the metal surface with high-temperature coal asphalt, a dense protective layer can be formed, which can effectively prevent metal products from corrosion and oxidation.
4.insulating materials.
In the wire and cable manufacturing process, high-temperature coal pitch is used as an insulating material. Because it has good electrical insulation performance and heat resistance, it can ensure that the wire and cable have good electrical performance and stability during use.
2. Production and processing of high-temperature coal asphalt.
The production and processing of high-temperature coal asphalt mainly include the following steps:
1.Raw material preparation: High-quality coal tar is selected as raw material, which is pretreated and dehydrated to remove impurities and improve the purity of raw materials.
2.Distillation: The pretreated coal tar is distilled to separate various components, such as light oil, phenol oil, naphthalene oil and washing oil.
3.Oxidation: The distilled light oil is oxidized at a certain temperature and pressure to generate oxidized asphalt. This process requires the addition of the right amount of catalyst and oxidant.
4.Blending: The oxidized asphalt obtained by oxidation is blended with other components to obtain high-temperature coal asphalt products. According to the requirements of different uses, high-temperature coal asphalt can be deeply processed, such as hydrogenation, desulfurization and dephosphorization.
3. Precautions for use.
1.High-temperature stability: High-temperature coal pitch has good high-temperature stability, but it is still necessary to avoid long-term exposure to high-temperature environment during use, so as not to affect its performance and service life.
2.Moisture-proof and rainproof: During use and storage, high-temperature coal pitch should be avoided from being eroded by moisture and rain, so as not to affect its performance and quality.
3.Safety protection: Because high-temperature coal pitch has a certain toxicity and irritation, it is necessary to pay attention to wearing protective equipment, such as masks, gloves, etc., during use. At the same time, storage and use should be kept away from fire and heat sources to prevent fire and other safety accidents. 
4.Waste disposal: For the waste high-temperature coal asphalt, it should be properly disposed of in accordance with relevant regulations to avoid harm to the environment and human health.
To sum up, as an important industrial material, high-temperature coal asphalt has a wide range of applications in road construction, waterproofing, anti-corrosion, insulation and other fields. Understanding its use, production and processing, and precautions for use can help to make the most of its performance benefits and contribute to the development of industrial production and construction.
