What is Pigment Carbon Black
Carbon black used as a pigment in paints, inks and plastics is called pigment black, or pigment black. Pigment carbon black is used in coatings, inks, and plastics. It also has the functions of conducting electricity, antistatic, shielding ultraviolet rays, and preventing resin aging.
What is Reinforcing Carbon Black?
The so-called reinforcing carbon black is that the addition of carbon black can enhance the wear resistance, tear resistance, tensile strength, modulus, swelling resistance, strength, and tear resistance of the rubber without damaging the rubber too much. flexibility.
The difference between pigment carbon black and reinforcing carbon black
Pigment carbon black is mainly used as carbon black for coloring pigments in inks, paints, coatings and other products. According to the coloring strength (or blackness) and particle size, it is generally divided into four types: high pigment carbon black, medium pigment carbon black, ordinary pigment carbon black and low pigment carbon black. It is mainly produced by contact method and oil furnace method.
Reinforcing carbon black is mainly used in rubber. Generally, the amount used in rubber accounts for 20%-70% of raw rubber, and the amount varies according to different rubber products. Carbon black for rubber is divided into high wear-resistant, reinforcing and semi-reinforcing varieties.
Different types of pigment carbon black and reinforcing carbon black
The models of pigment carbon black are: C111, C126, C166, C311, C326, C366, C611, C626, C666, etc.
Reinforcing carbon black is actually rubber carbon black, and their models are mainly N series carbon blacks. The main models are: N351, N375, N550, N660, N774, etc.
Common features of pigment carbon black and reinforcing carbon black
In fact, pigment carbon black also has a reinforcing effect, but compared with the reinforcing carbon black, the coloring effect of pigment carbon black is more prominent, and the same reinforcing carbon black also has a coloring effect, compared with the coloring effect of pigment carbon black, the reinforcement The role is more prominent. This is mainly because pigment carbon black and reinforcing carbon black are both a kind of carbon black, which are two branches divided by carbon black according to different functions.
