Carbon Black Usage And Synthesis |
Description | Carbon black is a finely divided form of carbon. It may explosively if suspended in air in the presence of an ignition source or slowly undergo spontaneous combustion upon contact with water. In addition, it is toxic by inhalation, with a TLV of 3.5 mg/m3 in air. Primary uses are in the manufacture of tires, belt covers, plastics, carbon paper, colorant for printing inks, and as a solar-energy absorber. |
Chemical Properties | It appears as black powdery particles with a particle size of 0 to 500 μm. The relative density is 1.8 to 2.1. It is insoluble in water and organic solvents. |
Uses |
1. It is edible black pigment. It can be used for pastry with the usage amount of 0.001% to 0.1%.
2. It can be used for food coloring agent. China provides that it can be used for rice, flour products, candy, biscuits and pastries with the maximum usage amount of 5.0g/kg. 3. Rubber industry uses it as a reinforcing filler. 2. Paint Inks applies it as coloring pigments in paint inks. 3. Used for the manufacturing of black paper such as packaging materials for photographic materials and the black paper made of high-conductivity black carbon in the radio equipment. 4. Carbon paper and typewriter; it is used when it is required for darker colors and can remain on the carrier. 5. Plastic coloring, ink, phonograph records, shoe polish, paint cloth, leather coatings, colored cement, electrodes, electronic brushes, batteries and so on. 4. As electric conductive agent of lithium ion battery; 5. Mainly used for rubber, paint, ink and other industries; 6. Used for the reinforcement of car tread and sidewall, hose, groove, industrial rubber products as well as conveyor belt. 7. Used for tire tread, surface tire repair, automotive rubber parts, conveyor belts, conveyor pads, etc., The vulcanized glue of this carbon black shows excellent tensile strength and abrasion resistance 8. It is mainly used for the reinforcement of tire belt, sidewall, solid tires, outer layer of roller, hose surface, industrial rubber products and car tire tread. 9. It is used for the reinforcement of the tire tread of car and truck, surface of conveyor belt and industrial rubber products. 10. For rubber reinforcement, coloring agent, metallurgy, rocket propellant 11. For rubber products to fill and reinforcement. 12. For rubber products, carcass, valves and other filling . 13. For paints and inks, plastics and other industries. 14. Mainly used for raw materials of battery as well as for conductive and anti-static rubber products. 15. In the rubber industry, it is used as the reinforcing agent and filter for the manufacturing of natural rubber and butyl rubber, being able to endow the vulcanized rubber with excellent tensile strength, elongation and tear resistance and so on. It should be mostly used for natural rubber-based large-scale engineering tires and a variety of off-road tires as well as being used for carcass and sidewall. In addition, it can also be used for high-strength conveyor belt, cold rubber products and drilling device. In light industry, it can be used as the filter of the paint, ink, enamel and plastic products. |
