Description
Hydrocarbons in the strict control the process conditions in qi
incomplete combustion in black or pyrolysis powder material. The
main composition is the element carbon, and with a small amount of
oxygen, hydrogen and sulfur, etc. Carbon black particles, particle
size between the approximate spherical close between *0 to **0 m.
Many particles often melt "or a 3 d together key branch shape or
fibrous aggregates. In the rubber processing, through the mixed
refine join in rubber reinforcing agent (see reinforced material)
and packing. Carbon black is the oldest one of industrial
products.
Small particles, structure, high surface and the surface roughness
of pure carbon black. Good conductivity Preparation of conductive
adhesive materials, the amount of carbon black not less than some
critical value, or plastic materials for too little not form
conductive carbon black channel, or can't cause field-emission,
make the conductivity of the sizing material can't meet the
requirements.
application
Mainly used as the rubber reinforcing agent and packing, the
consumption of about half of the consumption of rubber, rubber with
carbon black accounts for *4% of total carbon black, of which about
*0% for tyre manufacture. In addition, also used for printing ink,
paint and plastic colorants and plastic products BingBiJi of
ultraviolet light. In many other products, such as electrode, the
dry, resistors, explosives, cosmetics and polishing compound, it is
also important fertilizer. Furnace black is mainly used in rubber
products, the fine particle size of carbon black, the reinforcing
performance is superior; The higher the degree of structure carbon
black, the stress and set out the higher modulus. Fine particle
size of reinforcement are mainly used in tire surface, give the
tyres excellent wear resistance. Other parts of the tires, such as
the side of the tire, curtain with bunch of buffer layer, layer,
layer and lined with plastic material requirements anti-bending
cracked, ozone oxidation resistance, has the good recovery and low
heat production performance, general selection are coarse particle
size of the semi-reinforcing type (specific surface area less than
*0 m2 / g) furnace black. With slot black pigment is widely used in
printing ink, paint and plastic. Printing ink, especially news ink
pigment in the main use of black slot. In the coating manufacturing
process, high pigment slot car topcoat black gives senior excellent
black for and shiny, pigment in the black for general industrial
coatings slot. In addition, the pigment slot in black are also used
for polyolefin BingBiJi used to improve the ultraviolet light,
plastic products weatherability. Rubber with slot is mainly used
for off-road tires especially black and engineering of the tire
tread glue, it gives the tread higher strength and good wear
resistance. Hot tearing black is mainly used in rubber products.
For particle size thick and reinforcing performance is poor, only
for requires the greatest filling incremental occasions, such as
used in manufacturing rubber, rubber, sponge products, sealing
ring, tire, rubber lining of the formation lap and insulation
products, etc
