Medium-temperature coal pitch possesses various characteristics, including weak alkalinity, the ability to react with certain chemicals, good thermal stability, high viscosity, corrosion resistance, oxidation resistance, fatigue resistance, and excellent waterproofing properties.

1. Acidity and alkalinity: Medium-temperature coal pitch is weakly alkaline and reacts slowly with acids.

2. Reactivity: It can react with certain chemicals, such as oxidizing agents and reducing agents, but the reaction rate and products vary depending on the reactants.

3. Thermal stability: It has good thermal stability and can be used at high temperatures, but its decomposition temperature is relatively low, making it prone to oxidative degradation.

4. Viscosity: It has high viscosity, making it less fluid at high temperatures, while remaining flexible at low temperatures, allowing it to adapt to significant temperature changes.

5. Corrosion resistance: Due to its high viscosity, moisture and impurities are less likely to penetrate the material, giving it good corrosion resistance.

6. Oxidation resistance: It has certain oxidation resistance, allowing it to maintain its performance over a long period.

7. Waterproofing performance: Its high viscosity and low permeability give it excellent waterproofing properties, effectively preventing moisture penetration.

Medium-temperature coal pitch has a wide range of applications across various industries and fields.

1. Carbon industry: It is used as a binder for carbon electrodes and electrolytic aluminum anodes in the production of carbon electrode materials.

2. Waterproofing industry: It is used to make asphalt felt, building waterproofing layers, asphalt paint, and other waterproofing materials.

3. Rubber industry: It serves as a softener, reinforcing agent, tackifier, and dispersant.

4. Sealing industry: It is used as a sealing material for dry batteries, offering good adhesion.

5. Road engineering: As a raw material for asphalt concrete, it provides good wear resistance and crack resistance, making it widely used in the construction of roads, bridges, and tunnels.

6. Waterproofing materials: It is used to produce waterproof coatings, waterproof membranes, etc., offering excellent waterproofing effects and aging resistance.
