The basic idea of choosing Pigment Carbon Black

Before the first user in the choice of pigment carbon black to consider is : Do you want to use carbon black to achieve what are the requirements ?

The most important is that must communicate with Beilum carbon technical engineers, conduct joint technical evaluation of the material system , choose the more appropriate black varieties.

Coloring – choose high blackness, small particle size of the carbon black , but we must ensure that after a reasonable , fully distributed , otherwise it will run counter to reach the original requirement.

Pigment Carbon black primary particle size , structure and surface various groups will have a huge impact on the dispersion . Typically, the primary particle size of specialty black small, the structure is low, low volatile difficult to disperse , and vice versa are relatively easy.

Color use – Select blackness low size , easy to disperse carbon black.

UV use – mainly used in the plastics and rubber , choose medium size , slightly higher structure pigment black , and their optimum UV resistance

Black Carbon formulations user , the base material , the solvent and the resin properties are very significant impact on the final dispersion of the pigment black , particularly the choice of pigment black with a resin.

dispersing device : the type of dispersing apparatus under the same conditions, the dispersion effect is completely different . Correct selection of dispersing equipment is the user must pay attention to .

Volatile – specialty carbon black surface carrying amount of oxygen-containing groups , reflecting the physical properties of the surface of the pigment black , electrochemical properties and application performance , but also to measure the black market price of the important parameters .

Structure – carbon structure is a carbon black particles form aggregates characterize the degree of chain branches value, which indicates the degree of voids within the Black carbon  . Usually oil absorption (DBP absorption value).
