Carbon Black N330 hot selling

Carbon black (carbon black, also known as platinum), is a kind of amorphous carbon.

The main properties of carbon
1. Black degrees
Blackness refers to the black carbon has presented intensity. Carbon black, black degrees for shaded based mainly on the absorption of light by for a particular concentration of carbon black, the tiny, black, the higher level of light absorption. Black degrees by internal light carbon except by absorbing outside, also due to the influence of particle surface geometric institutions and produces a brighten effect of light scattering, it will reduce the black degrees. With the decrease of the size, light scattering reduced levels. Only for very fine black, improve the concentration of carbon black, can improve the blackness of carbon black, provide for bulky degree of light scattering dominate factors for increased with the carbon number, blackness corresponding reduced. Instead
2. Shading intensity
Shading intensity can understand to offset the effect of white dye whitening ability. Shading strength is also with the original particle size decreases and the decrease of the structure improvement.
3. Tonal
"Black particle" of light scattering, along with the decrease of the degree of particle decreased, while the redound effect, except impact is tonal, reasons are as follows: influence when can walk through a light for main colour color layer, black shortwave blue light red than the scattering effects polynikis more strongly. The fine carbon this effect of the more notable. Red light component as scattering loss is lesser, so into the depth of some shading layer. Blu-ray overall scattering intense, in the opposite direction, namely the rear scattering, and is also a strong reflected from shading layer. When observing reflection process, the fine carbon black chromatic appear blue tonal, can give a person the feeling of black degree is higher. If carbon black bulky, then correspondingly become brown hues. When observing transmission process, the same shading layer (not completely transparent film) tonal relations is exactly the opposite, with the decrease of the size, scattering the strong blu-ray through shaded, namely, the depth of the layer of smaller side through shading layer to blu-ray is less, from other ingredients in out. Therefore, by the side of the lack in observation, shading layer blu-ray ingredients in transmission process observation, they become brown hues. When the white attune ash (gray tone) situation, and in transmission process observation mass-tone shading condition similar, light plastic in contain black pigment in the white pigment particle back and forth, the smaller the scattering of carbon black, can make the visible light scattering blue light within the stronger, so more the rest of the red light part then transmission to come over with the yellow hue, showing the gray, conversely, such as when the shading with a thick particle size of carbon black, especially relatively bulky black, it will get light with the blue tonal gray.
4. Dispersion
Paint black more fine, carbon black and between the contact point amphiphiles, result the stronger cohesion between them, when pigment black incorporating begin feeding, namely carbon evenly distributed, beginning to do is scattered reactive to keep carbon black was great, eventually to separate particles of the highest blackness and shading. Compared with high structure carbon black, low structure carbon black is more likely to achieve high concentration, but in dispersion process but therefore need bigger scattered force. Carbon black dispersion properties, by the influence of structural degree due to high structure carbon black with good dispersion properties, so its shading strength is natural is stronger. When in use powdered carbon black, can appear the dust dispersed and headache, and therefore, can use muli or plasma substance. The price of prefabricated than mere carbon black to use pigment tall, but if considering clean process, high efficiency and technical less investment advantages, carbon black preparation has its value.
5. Light stability
Light can make plastic ageing, especially the ultraviolet ray in sunshine will accelerate plastic ageing. With uv absorption in using organic reagent and antioxidants can make the life span. However pigment black is still considered the best ultraviolet light stabilizer. Uv absorber black as pigments, mainly for extended plastic products in outdoor service life. Concentrations of small size for 0.5% 20nm) and carbon black (2% of carbon black (relatively coarse particle size 95nm). Almost equally light protective effect.
6. Food contact
All involves the food hygiene law provisions of commodities, including pigment pigments shall meet the prescribed pure standards. First of all, these standards stipulated the general pigment its levels of heavy metals, its components in 0.1 n hydrochloric acid and the solubility of gastric juice (ph), and the provisions as the content of aromatic ammonia. And then, especially about the pure silica formulated standard, and this one standard for national and different.

Classification of black
(1), according to the mode of production classification
Mainly divided into light black, gas black, furnace black and black. Slot
(2), the end-use classification
According to use different carbon, usually consist of pigment use carbon black, rubber use carbon black, conductive carbon black and special carbon black. Pigment, with black - international carbon shading capabilities, according to classified into three kinds, namely high usually in black, carbon black pigment and low pigment carbon black pigment. This classification usually use three letters, the former two letters indicate the shading capabilities, carbon last letters indicate the production methods. Rubber with carbon black with carbon black - rubber particle size is according to the original classification, but then changed to press nitrogen surface area classification. In addition, naming the carbon black pigment when vulcanization speed and structure factors, taking into account the by four system structure. The first English letters represent the sulfurization speed, N is for normal vulcanization rate, S representative slow vulcanization speed. 3 for Arabic Numbers behind. The first number represents carbon black, were listed as the nitrogen surface area range 0 ~ 9 levels. The second and third digital is responsible by the American association of material test D24.41 committee of carbon black and term designated, the structure reflects different levels.
