Acetylene Carbon Black
Methane black has the following characteristics compared to other carbon blacks: light in weight and low in density; high specific surface area and strong adsorption; stable chemical properties; good surface activity and high electrical conductivity; high purity with low ash and volatile content.
Compared to powdered acetylene black, granular carbon black offers advantages such as smaller volume for easier transportation; reduced dust pollution for improved working environment; and better flowability and dispersibility.
Molten carbon black is primarily used for conductivity, heat conductivity, coloring, and reinforcement, with main applications including:
1. Manufacture dry cells to enhance conductivity, increase discharge capacity, and extend discharge time.
2. Battery plates, including lead-acid batteries, lithium batteries, lithium-ion batteries, etc.
3. Conductive, antistatic rubber, silicone, and plastics, with small quantity, good reinforcement, corrosion resistance, good workability, and easy control over conductivity.
4. Cable shielding materials, accessories, and packaging materials.
5. Special tires and tire capsules, which serve as reinforcement and thermal conductors. The vulcanized rubber reinforced with them boasts high tensile strength and hardness, and excellent physical properties.
