Different types of coal pitch have different characteristics and uses. Here are some common types of coal pitch and their characteristics:
1.Modified asphalt: It is a coal asphalt that has been treated by a specific process, with a high softening point and good adhesion. It can be used to prepare impregnating agents and binders, and is widely used in the impregnation and bonding of carbon products.
2.Low-temperature coal asphalt: It has good fluidity, is a black solid at room temperature, softens when heated, and does not have cohesiveness. It is mainly used as a binder for paving, building materials, and can also be used in the production of paints, paints, etc.
3.Medium temperature coal asphalt: It has medium viscosity, is semi-solid at room temperature, softens after heating, and has good cohesion and fluidity. It is mainly used in the production of foundry sand, road construction, production of asphalt concrete, etc.
4.High-temperature coal asphalt: It has a high viscosity, is hard at room temperature, and softens after heating, but it is not easy to flow. It is mainly used in the production of carbon materials, the manufacture of electrodes, etc.
5.Asphalt-based carbon fiber: Asphalt-based carbon fiber is a special fiber prepared from coal asphalt, which has the characteristics of high strength, high modulus, and high temperature resistance. It can be used to make a variety of high-performance composite materials, such as aerospace, automotive, and other fields.
6.Mesophase asphalt: Mesophase asphalt is a kind of coal asphalt with a special structure, which has good fluidity and low viscosity. It can be used to manufacture a variety of high-performance carbon materials, such as electrode materials, capacitors, etc.
7.Coal asphalt coating: Coal asphalt coating is a kind of coating with coal asphalt as the main raw material, which has good anti-corrosion performance and weather resistance. It can be used in anti-corrosion coatings, anti-rust coatings and other fields.
8.Coal measure needle coke: Coal measure needle coke is a kind of carbon material prepared with coal pitch as the main raw material, which has the characteristics of high strength and high conductivity. It can manufacture high-power and high-power graphite electrodes, which are widely used in batteries, electric furnaces and other fields.
9.Impregnating asphalt: Impregnating asphalt is a kind of coal asphalt with good fluidity and permeability, which is mainly used for impregnating carbon products. It can improve the electrical conductivity and mechanical strength of products, and is widely used in electric power, metallurgy and other fields.
10.Binder asphalt: Binder bitumen is a kind of coal asphalt with good adhesion and high temperature resistance, mainly used in steelmaking, aluminum electrolysis and refractory industries. It can improve the strength and durability of the material, and extend the service life.
11.Bituminous-based carbon foam: Bituminous carbon foam is a lightweight, high-strength, high-porosity coal asphalt-based material, which has good thermal insulation and sound insulation properties. It can be used to make a variety of lightweight building materials, insulation, etc.
12.Carbon-carbon composite: Carbon-carbon composite material is a composite material with coal pitch as the matrix, which has the characteristics of high temperature resistance and high specific strength. It can be used to manufacture high-performance products such as various high-temperature devices, aerospace vehicles, etc.
13.Road construction asphalt: Road construction asphalt is a kind of coal asphalt suitable for high-load highways, which has good wear resistance and durability. It can be used to pave highways, airport runways, and other ground facilities that need to withstand large loads.
These different types of coal pitch have different properties and uses, which can be selected and applied according to specific needs.
In short, there are differences in the properties and applications of different types of coal asphalt, and the selection of the right coal asphalt needs to be decided according to the specific application scenarios and needs.
