What is the difference between pigment carbon black and ordinary carbon black?
Jun 23, 2022
Pigmented carbon blacks are generally good at coloring plastics. Pigment carbon black can be selected according to coloring characteristics or physicochemical properties. The variety of colored carbon black basically depends on the blackness of the finished product. The use of fine pigment carbon black can complete the coloring with high blackness requirements; PE garbage bags, plastic bags, cable materials and other products only need moderate blackness. Carbon black varieties with low specific surface area and high structure can be used; in plastic color matching. Small errors in carbon black weighing and dosing can lead to noticeable color differences. Therefore, it is recommended to use a larger particle size. Low pigment carbon black with poor tinting strength. In this way, the amount of carbon black can be slightly larger, and the weighing error is relatively small. And it has the advantages of better dispersion and lower price. For grey plastic. The use of finely pigmented carbon black tends to appear brownish-gray. The use of coarsely pigmented carbon black produces a bluish gray.
What is the difference between ordinary carbon black and pigment carbon black? Both the coloration and blackness of ordinary carbon black are very low, but the color of toxic carbon is different. Both the degree of coloration and weather resistance have been greatly improved. The color poison carbon is higher, and the pigment carbon black is a black pigment. It is also a good anti-ultraviolet agent. Mainly classified by particle size and blackness. High pigment carbon black (10-14 nm). Include: original granularity. Tinting strength, specific surface area, oil absorption. A range of indicators for PH volatiles. Such indicators are affecting the performance of pigmented carbon blacks as pigments. In different industries such as inks, coatings and plastics. Sealant build etc.
Ordinary carbon black is carbon black for rubber, which mainly plays a reinforcing role in rubber. The amount of rubber generally accounts for 20% to 70% of the raw rubber, and the amount varies with different rubber products. It can be divided into high wear resistance, reinforcement and semi-reinforcement, among which N110, N220, N330 and N339 are high wear resistance. N351 and N375 are reinforcements, while N550 and N660 are semi-reinforcing. N774 et al. The main inspection items are: DBP absorption value, specific surface area, etc. The structure directly affects the processing properties of the compound, as well as the mechanical properties and electrical conductivity of the vulcanizate.
In recent years,High structure carbon black filled vulcanizates have high modulus stress, good wear resistance and good electrical conductivity.
