摘要:
The invention relates to a method for producing carbon black or other flame aerosols, comprising the following steps: the heat is removed from the flame by dissipation and/or radiation; a thin gas boundary layer is formed; the flow formed by the flame and the gas boundary layer is accelerated or expanded; the obtained aerosol is withdrawn; and the cooling surface is cleaned. The invention further relates to a device for carrying out such a method and a black carbon having a maximum pH value of 6.0, a maximum ignition residue of 0.1 percent, and a maximum 5µm screening refuse of 200 ppm. The inventive black carbon can be used in rubber, plastic, printing inks, inks, inkjet inks, toners, lacquers, dyes, paper, bitumen, concrete, and other construction materials.
