Carbon black dye lower than the average price , and light resistance, heat stability and excellent resistance to migration etc. .
Carbon black is under controlled conditions , hydrocarbons ( oil or gas ) produced by incomplete combustion , three commonly used method of production methods for the tank , furnace and thermal cracking method.
When using carbon black as a coloring , the general channel black . Channel black is manufactured using natural gas , which has an average particle diameter of 5 to 30nm. Channel black with blue , pH value between 3.0 to 5.0 . It 's colored, generally divided into ordinary colored, medium tinting strength and high color strength three levels.
Black coloration than the addition , aging may be applied to the protective effect of shielding ultraviolet rays , to lower the surface resistivity of the effect.
Application of black plastic coloring size and color intensity is classified , the more fine particle size of carbon black , the blackness of the larger , higher UV shielding performance , anti-aging properties as possible. However , the finer the particle size of carbon black in plastics difficult to disperse in some way . Carbon black is used as coloring often referred to as " carbon black pigment ," which includes intermediate, generic , lower , or special carbon black pigment , suitable for different purposes. |
