1. Introduction to coal asphalt.
Coal pitch, also known as coal tar pitch, is a by-product of coal tar, which is a thermoplastic material. Coal pitch is mainly composed of phenolic compounds such as phenol, cresol and methylphenol, and also contains a small amount of aromatic compounds such as naphthalene and anthracene.
Second, the characteristics of coal pitch.
1.Physical properties: Coal pitch is a black, amorphous solid with unique properties, such as low density, low melting point, low volatility, etc.
2.Chemical properties: Coal pitch has good corrosion resistance, weather resistance and chemical resistance, and can resist the erosion of most chemicals.
3.Stability: Coal pitch has good stability at high temperatures, and is not easy to oxidize or age.
4.Adhesiveness: Coal pitch has good adhesion and can be used as a cementing agent for concrete, building structures, etc.
Third, the application of coal asphalt.
1.Construction: Coal asphalt can be used as a binder in concrete, building structure, etc., to improve the durability and stability of buildings.
2.Anti-corrosion field: Because coal pitch has good corrosion resistance, weather resistance and chemical corrosion resistance, it can be used in various anti-corrosion projects, such as pipeline anti-corrosion, equipment anti-corrosion, etc.
3.Chemical industry: coal pitch can be used as a chemical raw material such as fuel oil and fuel gas, and can also be used to produce various chemical products.
4.Other fields: Coal pitch can also be used in the manufacture of electrodes, coatings, rubber additives, etc.
4. Storage and transportation of coal asphalt.
1.Storage: Coal pitch should be stored in a cool, dry place, away from direct sunlight and high temperatures. Its quality and quantity should be checked regularly during storage.
2.Transportation: During transportation, collisions and friction should be avoided to avoid damage to the packaging and products. At the same time, relevant laws, regulations and safety regulations should be complied with to ensure the safety and environmental protection of the transportation process.
5. Precautions.
1.When using coal asphalt, protective equipment such as gloves, masks, etc., should be worn to avoid irritation to ** and respiratory tract.
2.Avoid prolonged exposure to coal pitch to avoid allergic reactions to it.
3.When dealing with waste coal asphalt, it should be classified in accordance with relevant regulations to avoid environmental pollution.
