These 14 applications of white carbon black (2) 08
Application in toothpaste

Precipitated silica is currently the main variety of friction agents for toothpaste. Precipitated white carbon black has a large total specific surface area, strong adsorption capacity, many adsorbed substances and uniform particles, which is beneficial to improve transparency. Because of its stable nature, non-toxic and harmless, it is a good raw material for toothpaste. The refractive index of white carbon black is between 1.45 and 1.50, which is very close to the refractive index of other ingredients in toothpaste, so when mixed together, it acts as a transparent agent. This feature is used to make transparent toothpaste, which is also a function that any other friction agent does not have.

Application in cosmetics

The excellent properties of white carbon black, such as non-toxic, odorless, and easy to color, make it widely used in the cosmetics industry. White carbon black is used in skin care products and cosmetics to make the skin feel smooth and soft ("ball bearing effect"). Perceive skin wrinkles and blemishes. In addition, the thixotropy of silica can prevent pigments from settling and can be used in products such as lipsticks and nail polishes.

Application of white carbon black in rubber shoes

The white carbon has high black and white and fine particles. The vulcanized rubber made by using transparent white carbon black has high transparency and can improve the comprehensive physical properties of the rubber. Therefore, the white carbon black is widely used as the main reinforcing filler in high-end leather shoes and sports shoes. In the sole making materials, especially in the transparent and translucent sole compound. It can improve the wear resistance, hardness, tensile strength and tear strength of the sole.


11
Application in the pharmaceutical industry

White carbon black has physiological inertness, high absorption, dispersibility and thickening properties, and has been widely used in pharmaceutical preparations. Researchers in France found that adding a small amount of fumed silica to ranitidine, rimazide, and pirenzepine will change their fluidity; in drugs containing griseofulvin, adding a small amount of fumed white carbon A small amount of fumed silica can change its dissolution rate, that is, change the dispersibility and absorption of insoluble drugs in water; adding a small amount of fumed silica to powders containing aspirin will change the antistatic properties of the powder sex.

As an absorbent and dispersant, white carbon can also be used in the production of western medicine tablets such as vitamin C; in the production of medical capsules, a small amount of white carbon black can act as a carrier. According to the editors of China Powder Network, Japanese researchers have discovered that adding a small amount of white carbon to the formula of polyethylene packaging materials can be used to make sterile packaging films for medical items.


12
Application in ink

White carbon black is also used to control the flow of printer ink so that it cannot flow or sag freely to obtain clear printing. In beverage cans, it controls the use of high-speed spray paint. Fumed white carbon black is also used as a dispersant and flow control agent in the toner cartridges of copiers and laser printers.


13
Application in pesticides

Silica can be used as herbicides and insecticides in pesticides. In the two common herbicide dinitroaniline and urea mixtures, adding a small amount of fumed white carbon black and precipitation white carbon black will prevent this mixture from caking. In the granular pesticide formulation, adding a small amount of fumed white carbon black will more effectively control and prevent the production of harmful organisms. Silica can also be used as an absorbent for pollutants in the soil and absorb pollutants in the soil.


14
Application in daily necessities

Food packaging bags with white carbon black can play a role in preserving the freshness of fruits and vegetables. White carbon black can also be used as a high-efficiency bactericide for preventing and treating various diseases of fruits; in the production of alcohol, a small amount of white carbon black is added to purify beer and extend the shelf life. In the braid containing vinyl chloride, adding a small amount of fumed white carbon black will change its performance. The white carbon black acts as a matting agent. It only stays on the surface of the braid and does not penetrate the braid.

According to the editors of China Powder Network, silica still has important applications in other fields. For example, white carbon black can also be added to aviation silicone rubber as a special heat-resistant additive to improve its high temperature resistance; white carbon black can also be used as an absorbent for pollutants in the soil to absorb pollutants in the soil; in the field of construction materials , Adding nano-silica and natural zeolite to the self-compacting mortar can reduce the penetration of chloride ions into the self-compacting mortar, thereby improving the mechanical properties and durability of the self-compacting mortar.
