Abstract: The invention relates to lamp blacks having a DBP value of less than 100 ml/100 g. The invention also relates to a method for producing said lamp black, wherein lamp black is mechanically size-reduced in a rotary ball mill. The lamp blacks according to the invention can be used in carbon black dispersions, paint systems, printing inks, plastic mixtures and rubber mixtures.

Abstract: La invención se relaciona con un negro de humo que tiene una distribución del tamaño del agregado la cual tiene una relación de (d90-d10)/d50 de menos de o igual a 1.1. Los negros de humo son producidos mezclando aire caliente si se desea con una mezcla de gas que comprende un gas de transporte y una alimentación de negro de humo, haciendo pasar la mezcla de gas hacia un tubo quemador, quemando la mezcla de gas en las aberturas del tubo quemador, y extrayendo las llamas bajo succión junto con el aire jalado del ambiente libremente bajo succión desde el exterior, a través de un espacio estrecho, frío y llevando a cabo el enfriamiento, teniendo el espacio estrecho, frío, una relación de altura (h) a ancho (b) de 1-100, siendo el ancho (b) de 0.5 a 10 mm, y siendo la velocidad de flujo en el punto más estrecho del espacio 10-200 m/s. Los negros de humo de la invención pueden ser usados como carga no reforzante, carga reforzante, estabilizador de UV, negro conductor, pigmento o agente reductor.

Abstract: Carbon black with an aggregate size distribution ratio ((d 9 0-d 1 0)/d 5 0) of = 1.1, is new. Independent claims are included for: (1) preparation of the carbon black; and (2) device for executing the above process comprising a burner and a cooling surface against which the flame is directed, where the cooling takes place through a self-constricting gap, which has a height/width ratio of 1-100 mm, where the width is related to the upper edge of the gap and is 0.5-10 mm and the flow velocity at the narrowest point of the gap is 10-200 m/s.

Abstract: The invention relates to a carbon black having an aggregate size distribution which has a (d90-d10)/d50 ratio of less than or equal to 1.1. The carbon blacks are produced by admixing hot air if desired to a gas mixture comprising a carrier gas and a carbon black feedstock, passing the gas mixture into a burner pipe, burning the gas mixture at the burner pipe openings, and drawing the flames under suction, together with the ambient air drawn in freely under suction from the outside, through a cooled, narrowing gap, and carrying out cooling, the cooled, narrowing gap having a height (h) to width (b) ratio of 1-100, the width (b) being 0.5 to 10 mm, and the flow rate at the narrowest point of the gap being 10 - 200 m/s. The carbon blacks of the invention can be used as non- reinforcing filler, reinforcing filler, UV stabilizer, conductive black, pigment or reducing agent.

Abstract: 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 fl ow formed by the flame and the gas boundary layer is accelerated or expanded; t he 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 5~m screening refuse of 200 ppm. The inventive black carbon can be used in rubber, plastic, printing inks, inks, inkjet ink s, toners, lacquers, dyes, paper, bitumen, concrete, and other construction materials.
