熱分解カーボンブラック：改質戦略と応用展望
Pyrolysis carbon black (also known as recovered carbon black, rCB) is a solid product obtained from high-temperature pyrolysis of waste tires, waste rubber, and other organic wastes under oxygen-free or oxygen-limited conditions. Difference from Conventional Carbon Black Conventional Carbon Black: Produced by incomplete combustion of petroleum or natural gas. The process is controlled, yielding uniform purity, structure, and surface chemistry. Pyrolysis Carbon Black: Composition is more complex, containing inorganic impurities (zinc, sulfur, silica, ash) and residual hydrocarbons from tire additives. Its surface activity is low, structure irregular, and direct performance significantly lower than conventional carbon black.Thus, modification is essential before rCB can be reused as reinforcing filler in rubber, plastics, […]
