Coal pitch is a by-product of the high-temperature dry distillation process of coal, and it is a dark brown viscous liquid or solid substance that has a variety of uses. Mainly classified according to different standards, coal pitch can be divided into different categories:
1. Classification by form:
Liquid coal asphalt: liquid at room temperature, suitable for road irrigation, paint production, etc.
Solid coal asphalt: It is solid at room temperature, suitable for the production of waterproofing membranes and building sealing materials.
2. Classification by use:
Asphalt for waterproofing materials: used in the production of waterproofing membranes and roof waterproofing, etc.
Asphalt for sealing materials: used to make building sealing materials, such as rubber pads, etc.
Asphalt for coatings: used in the production of anti-rust and anti-corrosion coatings.
Asphalt for insulating materials: used to make the insulation layer of wires and cables.
3. Classification according to coal grade:
Hard coal pitch: Obtained from hard coal tar, usually in the form of a hard solid.
Soft coal pitch: obtained from soft coal tar, usually in a soft and viscous solid.
4. Classification according to production methods:
Distillation coal pitch: Coal tar is distilled to separate it into a variety of different components to finally obtain coal pitch.
Oxidation coal asphalt: The coal tar is oxidized to make it oxidize, and then the coal pitch is obtained through processing.
5. Classification according to quality level:
Ordinary coal asphalt: a low-quality coal tar processing product, mainly used to make waterproof coatings, anti-corrosion coatings, etc.
Modified coal asphalt: a coal tar processed product processed by a special process, with higher quality and performance. It is mainly used to make high-performance waterproofing membranes and anticorrosive coatings.
6. Classification according to appearance color:
Black Coal Pitch: Appears black coal pitch.
Colored coal pitch: Different colors of dyes are added to the black coal pitch, and different colors of coal pitch can be made according to your needs.
In addition, coal pitch has a wide range of applications in several fields, such as:
1. Road construction: used as an additive for road asphalt concrete to improve the durability and waterproofness of the road surface.
2. Waterproof materials: produce waterproof membranes for waterproof treatment of roofs, basements and other building structures.
3. Building sealing materials: used to seal the joints of buildings to prevent moisture penetration.
4. Anti-corrosion coating: used for anti-rust and anti-corrosion coating of metal structure.
5. Insulating material: used for the insulation layer of wires and cables to ensure the safety of electric energy transmission.
6. Electrode material: as a binder for carbon electrode, it is used in the metallurgical industry.
7. Briquette binder: used to make industrial briquette, improve combustion efficiency and reduce pollutant emissions.
It should be noted that there are environmental and health risks in the use of coal pitch, and appropriate measures should be taken for safe handling and protection.
