a) the essential characteristics of the carbon black: carbon black of primary particle size, surface structure and a variety of groups will have a huge impact on the dispersion. Usually the primary particle size of carbon black small, low structure, low volatile and difficult to disperse, and vice versa relatively easy. b) the user's recipe: Carbon black user recipe, binder, solvent and resin properties are very significantly affect the final dispersion of carbon black, especially the choice of carbon black with a resin. c) dispersing devices: different dispersion devices dispersing effect under the same conditions are completely different. The correct selection of the dispersion device is user must pay attention to. Carbon black pigment can often better to plastic coloring, optional carbon black pigment or coloring characteristics according to the physical and chemical properties, color choice with black varieties are basically finished with blackness must be reached. With very fine carbon black pigment can complete blackness particularly high coloring; PE garbage bags, plastic bags, cable materials and the like product only moderate levels of blackness, you can use a lower specific surface area, high structure carbon black varieties ; Plastic color, small errors that occur when carbon weighing and batching will result in a clear color, therefore, should adopt the larger particle size, poor color strength low carbon black pigment, so the amount of carbon black can be a little large, weighing error is relatively small, and there is good dispersion, low-cost advantages. For gray plastic, the use of carbon black pigment granules are often presented with a gray-brown, while the use of coarse particles of carbon black pigment can produce bluish gray.
