Carbon black is an important reinforcing agent for rubber products. The carbon black used in the tire industry accounts for about 75% of the carbon black required by the entire rubber industry. Carbon black in the rubber industry is used to manufacture various types of tires, such as automobile tires, tractor tires, aircraft tires, bicycle tires, electric vehicle tires, etc.;

"Rubber products" other than tires. Such as hoses, tapes, rubber shoes, etc. The annual consumption of carbon black in rubber products accounts for about 25% of the carbon black used in rubber. Carbon black has excellent reinforcing properties, improves tire wear performance, greatly improves tire mileage, and also improves physical and mechanical properties such as tensile strength and tear strength of rubber compounds. Carbon black is a rubber reinforcing filler and the second rubber raw material after raw rubber.

The dispersion level of ORILON carbon black 50L can make the color, hue, viscosity, gloss, stability and extrusion characteristics of plastics meet better requirements. However, the price of Oulilong carbon black is higher, and it is mostly used in high-grade rubber.

Carbon black for plastics accounts for a large proportion of non-rubber applications. Not only can it be colored or toned, but it can also play a role in preventing UV aging, antistatic or conductive. In order to make carbon black have good dispersibility in plastics, carbon black is usually pre-dispersed in a certain medium, which is called color masterbatch or color masterbatch; then this masterbatch is diluted with an appropriate proportion of plastic. Very fine pigment carbon black can be used to complete the coloring with particularly high blackness requirements. Products such as PE garbage bags, plastic bags, and cable materials only need medium blackness, and carbon black varieties with lower specific surface area and higher structure can be used. ; When plastic toning, small errors in carbon black weighing and batching will lead to obvious color difference. Therefore, low-pigment carbon black with larger particle size and poor tinting strength should be used, so that the amount of carbon black can be slightly Larger, the weighing error is relatively small, and it has the advantages of better dispersion and lower price.

Carbon black has high light absorption, so it can effectively prevent the photo-oxidative degradation of plastics when exposed to sunlight. Carbon black work

The functions of UV stabilizers in plastics include: converting light energy into heat energy; protecting the plastic surface from radiation of a certain wavelength; intercepting atomic groups to produce anti-aging effects, thereby preventing catalytic degradation. Ultraviolet rays are particularly harmful to polyolefins. Tests have shown that when the concentration of carbon black with a certain fineness is 2%, it can achieve perfect ultraviolet shielding effect. The protective effect of carbon black on UV aging of plastics depends on the particle size, structure and surface chemistry of carbon black. When the particle size of carbon black is small, due to the increased surface area, its light absorption or shading ability increases, so the UV protection effect is enhanced, but the particle size is less than 20nm, its protective effect tends to the same level, because when the particle size is too small, the reverse Scattering is reduced, and light that continues forward threatens the stability of the polymer.

Carbon black is used in the paper industry as a black pigment to produce black, grey, or dark paper and cardboard. Compared with other organic pigments, carbon black is relatively cheap and has good lightfastness and chemical properties. Moreover, carbon black has good coloring and light-shielding properties, and can also make paper conductive. Therefore, paper colored with carbon black is often used in decorative materials, light-proof packaging materials (such as packaging paper for photosensitive film), various atlas paper, high-voltage cable paper and other special papers.

Carbon black is the main pigment in black inks. Most of the printing inks use high-quality pigment carbon black. The basic properties of carbon black affect the quality of the ink and the quality of the printed matter to a large extent. The requirements of printing ink for carbon black are mainly blackness, hue, fluidity, viscosity, drying and thixotropy.

Carbon black can be used as colorant in fiber textile. Carbon black can also be used in cement or asbestos cement, roofing materials, asbestos cement boards, cement building boards, concrete pavements for highways, etc. It is a pulverization accelerator for the manufacture of Portland cement, shortens the pulverization time, and makes the particle size finer and increases the fluidity of the dry powder. Adding carbon factor to make basic refractory bricks, such as magnesia bricks or magnesia bricks, reduces the invasion and penetration of high temperature materials and prolongs the service life of refractory bricks.
