| Effect of plastic properties of carbon black characteristics (blackness and particle size) | |
| Release time：2016/9/23 | |
Blackness is directly related to carbon black pigment particle size, particle size, the higher the degree of pigment carbon black. This is because, although primary

particles fused into a native aggregates, but it can still play a role specific surface area, the finer the primary particle, the larger the surface area of their body cohesion. The appearance of color is more black, anti-ultraviolet light better. Since the fine carbon black particles is higher than the absorbance of coarse particles of carbon black, so a stronger coloring power. But when the particle size reduction, due to the blue light is preferentially absorbed into a brownish tone to this end.
Due to the fine primary particles of carbon black gives a greater surface area, so the need for more energy wetting and dispersing energy.
