A kind of amorphous carbon. Light, loose and very fine black
powder, specific surface area is very large, ranging from 10-3000m2
/ g, is the organic (natural gas, heavy oil, fuel oil, etc.) under
conditions of insufficient air by the incomplete combustion or
thermal decomposition derived from the product. The proportion of
1.8-2.1 made from natural gas called "gas black," made from the
oils known as "lamp black," made by the acetylene called "acetylene
black." There are also "slot black" "furnace black." Distinguish
between the performance of carbon black by the "reinforcing carbon
black", "conductive carbon black", "wear black" and so on.
Carbon black has the following characteristics:
1. The best black pigment.
2. Is almost the cheapest paint.
3. Tinting strength and hiding power most of the pigment.
4. Visual sensory and neutral.
5. The most stable pigments, heat resistance, chemicals,
light-fastness.
Uses:
For high-middle and low ink, paint, printing and dyeing and other
chemical industries, for example, coloring, anti-ultraviolet light,
or electrical conductivity and so on.
1, coloring with carbon black
Pigment Carbon Black in general can be a good color to the plastics
can be colored according to physical and chemical properties of
selected features or pigments carbon black, carbon black coloring
of the species of choice are basically finished with the blackness
that must be met determined. With fine carbon black pigment can
complete degree requirements are especially high in black color; PE
garbage bags, plastic bags, cable materials products only moderate
levels of blackness, you can use a lower specific surface area,
structure, higher carbon black varieties ; plastic palette, the
carbon black when weighing and batching small errors will lead to
significant chromatic aberration, therefore, should adopt a larger
particle size, poor color strength, low carbon black pigment, so
that carbon black can be slightly larger, weighing error is
relatively smaller and have better dispersion and low price
advantages.
