Acetylene Carbon Black Ball

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

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.

Structure

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.

Surface chemistry

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.
