Our company uses high-quality calcium carbide to produce acetylene gas and through high temperature pyrolysis, gain the black light powder, acetylene carbon black. Compared with other carbon common, it has light weight, small proportion and fine particles, and it disperses more evenly in counter electrodes. It boasts excellent acetylene formula, large specific surface area, favorable absorption performance, great liquid absorbability, stable chemical stability, good surface activity and high conductivity.
Functions and mechanism of acetylene carbon black:
Acetylene carbon black is pure amorphous carbon with excellent water absorption and adsorptivity, small resistivity and good conductivity. With black used, the conductivity of the lead active material is increased. In particular, during post-discharge, if the lead sulfate crystal is increased significantly, the feature of improving conductivity of lead active substances is more obvious. Meanwhile, addition of acetylene carbon black also increases the porosity and the amount of liquid in the plate, benefits the supply of acid at the time of discharge, and can improve the discharge performance of the plate and provide a higher discharge capacity at low temperature. Acetylene carbon black has strong absorbing performance, so it can adjust the distribution of surface active substances or organic bulking agents, reduce their excessive aggregation on the surface of lead and lead sulfate, and improve the charging capacity during the crystallization of metallic lead and lead sulfate. The increase in porosity is conducive to the diffusion of sulfate ions, prevents the discharge hole from blocking, and increases the real surface area of the electrode, which can greatly improve the battery performance.
1.Dry batteries: Acetylene carbon black, also known as carbon common, has excellent conductivity and is widely used in battery production.
2.The particle size of acetylene carbon black is medium, and its structure is very high, the ash content and the volatile content are very low, so the resistivity is extremely low. The special acetylene carbon black for battery can improve the battery storage time, and extend its service life.
3.Conductive, anti-static rubber, silicone and plastic, and cable shielding material. As a kind of functional high-conductivity filler, conductive carbon black mainly applies to conductive and anti-static coating, plastic, rubber, adhesive, ink, battery and cable shielding material. It’s widely used in conductive, electromagnetic shielding and anti-static fields of industrial departments including electronics, electromechanical, communications, printing, aerospace and weapons.
4.Special tires and tire capsules. Acetylene black carbon plays a role in reinforcing and thermal conductivity in tires. The vulcanized rubber reinforced with it boasts high tensile strength and hardness as well as good physical properties.
5.Electromagnetic wave insulation and gas dispersion electrode, catalyst material and microwave absorbing material. The microwave absorbing material mainly consists of the electromagnetic wave absorber and the base material. From the working principle of microwave absorbing material, we can know that its microwave absorbing ability is closely related to the absorbing ability of the absorber. Acetylene black carbon is the electrical-loss inorganic absorbing material which has good wave absorption ability and a cheap price.

1.The acetylene carbon black is non-hazardous chemical, but its surface has hygroscopicity, so damp-proof measures are necessary. Usually three-tier packaging (inner kraft paper bag, the middle layer of plastic bags, and the outer plastic woven bags) is adopted, and moisture-proof kraft paper bags, ton bags can be used for package. Customers can also request the use of PE bags and other special packaging.
2.The product should be stored in a cool, dry, ventilated warehouse, away from the sources of fire and heat, and isolated from the oxidant. It should not be moisturized, hooked, pulled, thrown or pressed forcibly. For leakage, the fallen carbon black shall not be mixed into the product.
3.In work, people should wear masks and work clothes to prevent inhalation; after work, have a shower and change clothes to keep the body clean. If there is a fire, use water and other fire-fighting equipment to put out the fire.
