There are soluble and insoluble black pigments, and there are inorganic and organic differences. And many manufacturers will give priority to pigment carbon black in black pigments, which makes friends who don't know why don't know why, so what kind of advantages does pigment carbon black have, so that all walks of life are giving priority to pigment carbon black? The following is Why do you choose pigment carbon black for black pigments?
Pigment carbon black is known as the best black pigment
Carbon black is an important dye second only to titanium dioxide. The annual consumption of carbon black in the world is about 6 million tons, and the characteristic carbon black in coloring and other uses is about 250,000 tons. It can be said that carbon black is a pigment in black pigments. has a high status.
Pigment carbon black is almost the cheapest pigment
Carbon black is a fine powder produced by incomplete combustion of carbon-containing raw materials (mainly petroleum). The appearance is pure black fine particles or powder. Compared with other black pigments, the cost of carbon black is very low , which is why many friends prefer pigment carbon black.
The coloring power and hiding power of pigment carbon black are the strongest pigments
The light absorption rate of fine particle carbon black is higher than that of coarse particle carbon black, so the tinting power is stronger. The structure of carbon black is the form of carbon black aggregates. Generally, the more chain branches, the denser the structure, the higher the structure, and vice versa. High structure, good dispersion performance, strong covering ability. It is also black, but in comparison, the coloring power of pigment carbon black is relatively strong.
Pigment carbon black is visually neutral
Carbon black is visually neutral, which avoids fatigue and is more conducive to making pigments. This is why many friends like to use pigment carbon black.
Pigment carbon black is the most stable pigment
Carbon black is chemically inactive at room temperature, very stable, difficult to produce chemical reactions with other molecules, and has strong acid and alkali resistance. Moreover, carbon black has high-quality properties such as heat resistance, chemical resistance, and light resistance.
Pigment carbon black has such characteristics that people give priority to carbon black when using black pigments. How to choose carbon black products for different purposes depends on the specific production process of the manufacturer. Of course, everyone gives priority to pigment carbon in black pigments. Black, but it is not necessary to use pigment carbon black. It also depends on whether your own production process is suitable for using carbon black as a raw material.
