The application of finely ground carbon black are very wide. And it has excellent properties such as small particle size, large specific surface area, large surface energy, strong adsorption capacity, high purity, high stability, reinforcement, thickening and thixotropy. At the same time, it has excellent properties in light absorption, magnetism, thermal resistance, It also shows unique properties in terms of catalysis and melting point, and is widely used in various industries as additives, catalyst carriers, petrochemicals, decolorants, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, and metal softeners, Polishing agent, insulation filler, advanced daily cosmetic filler and spray material, medicine, environmental protection and other fields.
As a carbon black vertical roller mill manufacturer, Guilin Hongcheng will introduce to you today the application of finely ground carbon black processed by carbon black vertical roller mills.
1. Paint industry
The refractive index of amorphous silica is 1.457, which is similar to that of conventional resin coatings. Therefore, amorphous silica is the first choice for matting agents in high-end coatings. It has good optical properties when used in varnishes and can produce matte and Matting effect.
As we all know, wind power is an environmentally friendly green new energy. The adhesive used on the blades is a highly polar epoxy resin system. The blades are large in size and cross-sectional area, so they require extremely high bonding performance and strength. High, with extremely high requirements on viscosity, anti-sag performance and anti-settling performance. Since epoxy resin is a highly polar resin system with strong polar groups, hydrophilic fumed silica is generally used, which is prone to solvent-based effects, that is, the viscosity and suspension effects are very good just after dispersion. , but after being left for 7 to 10 days, the polar groups destroy the hydrogen bonds forming the network structure, leading to the cracking of the hydrogen bonds and problems such as thinning, non-thixotropy, and filler precipitation. Therefore, it is recommended to use strong adhesives for wind blades. Hydrophobically modified nano-level fumed silica has strong stability and avoids solvent-based effects.
2. Rubber industry
Silica is a widely used environmentally friendly rubber reinforcing agent. Silicone rubber has excellent high temperature resistance, insulation, heat insulation, chemical resistance, anti-pollution and other properties. It is irreplaceable in the fields of national defense industry, architectural decoration, aerospace and other fields. effect.
When used as a tire tread reinforcing agent, it can reduce rolling resistance while maintaining excellent wet skid resistance. It can also save fuel and reduce automobile exhaust emissions. At the same time, rolling resistance can be reduced by about 30%. It is an ideal choice for manufacturing "green tires" important raw materials.
After AMI modification of silica particles, the interaction between particles is reduced and the agglomeration is reduced. When used to dope rubber, it has a certain promotion effect on rubber vulcanization, and the rubber molecular chains are arranged more orderly.
3. Daily life
In recent years, super absorbent resin is a new type of polymer fine chemical product. It has been widely used in industrial supplies, daily sanitary products, medical treatment, agriculture, civil construction and other fields. In particular, the demand for daily sanitary products and agriculture is increasing day by day. . Super absorbent resin has small particle size, high salt water absorption rate, fast absorption speed, and low monomer residue. It is commonly used in daily sanitary products including baby diapers, adult diapers, ultra-thin diapers, sanitary napkins, pet pads, and nursing pads. , absorbent paper, dust-free paper, toothpaste, etc. In the production process of baby diapers, diapers, sanitary napkins, etc., the quantification of super absorbent resin is a key link. The function of vapor phase silica in water-absorbent resin is to increase the fluidity of water-absorbent resin, prevent agglomeration, facilitate the flow of highly water-absorbent resin in pipes, avoid pipe blockage, and improve production efficiency.
4. Biological filtration
Biological filtration is a typical air pollution control process that treats volatile organic compounds. The mass transfer of hydrophobic VOCs to biofilms is limited, resulting in low biofilm removal efficiency. In order to enhance the migration of hydrophobic organic matter, adding hydrophobic fumed silica to the biofilter can remove pentane, etc.
