Coal asphalt manufacturer Shen Min
Coal pitch is a multi-purpose chemical product that is widely used in many industries, including but not limited to:
1. Road construction industry: As a blender of road asphalt, coal asphalt can improve the durability, waterproof performance and anti-skid resistance of asphalt concrete, so it is commonly used to maintain and repair roads and improve the service life of road surface.
2. Waterproof material industry: Due to its good waterproofness, coal pitch is used in the production of waterproofing membranes and roof waterproof coatings.
3. Building materials industry: As a sealing material and binder for building joints, coal pitch can prevent moisture and gas penetration, and is used to bond masonry, concrete and other materials.
4. Coating industry: coal asphalt is used to produce anti-corrosion coatings and waterproof coatings to improve the waterproof performance of buildings.
5. Metallurgical industry: as a binder for carbon electrodes, it is used in the production of graphite electrodes.
6. Refractory material industry: used to make blast furnace clay, waterless clay, charging materials, blast furnace ramming materials, magnesia carbon bricks, amorphous refractories, etc.
7. Other industries: rubber softeners and plastic improvers are also application fields of coal asphalt, which can improve the softness and processing performance of rubber, and improve the processability and physical properties of plastics.
Performance analysis of coal pitch.
1. Physical properties.
The physical properties of coal pitch are mainly manifested in its appearance, color, density, hardness, etc. Coal pitch is black or black-brown in color, has a special greasy feel, and its density is usually in the 10-1.2 grams of cubic centimeters, the hardness is low, and it has good plasticity and adhesion.
2. Chemical properties.
Coal pitch is a mixture of a variety of complex polymer organic compounds, the main components of which include polycyclic aromatic hydrocarbons, aliphatic compounds, phenols, etc. These compounds determine the chemical properties of coal pitch, including stability, oxidation resistance, corrosion resistance, etc.
3. Adhesion.
Coal pitch has good adhesion and is able to bond various materials, such as steel, cement, wood, etc. This bonding property makes coal pitch widely used in buildings, roads, bridges and other fields.
4. Stability.
Coal pitch has good stability and can maintain the stability of its performance in harsh environments such as high temperature, low temperature, supermarket, acid and alkali. This stability makes coal pitch a reliable building material in many engineering fields.
5. Toxicity. Coal pitch contains a variety of harmful substances, such as benzopyrene, formaldehyde, etc., which are harmful to human health. Long-term exposure to coal pitch may cause symptoms such as headaches, nausea, vomiting, and may even lead to diseases such as cancer. Therefore, when using coal asphalt, attention should be paid to taking corresponding protective measures to reduce the harm to human health.
