The acetylene carbon black ball is high quality carbon black made of granular acetylene carbon black.
Observe acetylene carbon black ball with the electron microscope, and we can find that acetylene carbon black ball has complicated structure with some ball particles fused together. The size of ball particles is known as “particle size” while the size of the particle chain as “structure”. All functional groups such as hydroxyl or carboxyl groups exist on the surface of carbon black, and the amount or composition is referred to as "surface chemistry". The three terms, "particle size", "structure" and "surface chemistry" are the basic properties of acetylene black and together they are known as three main features. When they mix with ink, paint or resin, the three main properties make a great impact on actual performance such as blackness and dispersibility.
Particle size is the basic feature that greatly influence blackness and dispersibility when carbon black mixes with resin or other carrier. Normally, the smaller particle size, the higher blackness of conductive carbon. However, with the increase of coagulating power, it’s difficult to disperse.
Like the particle size, the size of the structure also influences the blackness and dispersibility of the carbon black. Generally, an increase in the size of the structure improves dispersibility, but reduces blackness. Carbon black of a larger structure particularly shows excellent electrical conductivity.
Various kinds of functional groups exist on the surface of carbon black. The affinity of carbon black with ink or paint varies depending on the type and amount of the functional groups. Through oxidation treatment, carbon black with a large number of hydroxyl groups have much higher affinity with ink or paint, showing excellent dispersibility.

Acetylene carbon black ball is mainly used in:
1.Conductive, anti-static rubber, silicone and plastic: the small ratio, good reinforcement, corrosion resistance, good processability, easy to control the conductivity. Conductive silicone rubber and plastic have been widely used in the modern industry. They are mainly used in electronic equipment switch electric shock, liquid crystal display, coal mine transportation tape, mine air duct, laser printer, electrostatic copier anti-static roller, carpets, anti-static plastic sheet in the hospital operating room, the hose in medical machinery, anti-static flooring in electronic production, gloves, wrist, carpets, air (aircraft) tire surface, labor protection products, anti-static safety helmet, safety shoes etc.
2.Tire capsule: It plays a role in reinforcing and thermal conductivity. The vulcanized rubber reinforced with it boasts high tensile strength and hardness as well as good physical properties.
3.High-voltage cables, cable shielding materials, accessories and packaging materials: Smear it to the cable insulation layer as cable shielding layer. On one hand, it can reduce cable internal transmission signal leakage, reduce external electromagnetic radiation pollution, and make the information more confidential; on the other hand, it can effectively prevent the external electromagnetic environment from interfering the cable signal, and ensure quality of signal transmission.

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.
