11 Application in the pharmaceutical industry
Silica has physiological inertness, high absorption, dispersibility and thickening properties, and has been widely used in pharmaceutical preparations. French researchers found that adding a small amount of fumed silica to ranitidine, metamide, pirenzepine and other drugs would change their fluidity; in drugs containing griseofulvin, adding a small amount of fumed silica would change their fluidity. A small amount of fumed silica can change its dissolution rate, that is, to change the dispersibility and absorption of poorly soluble drugs in water; adding a small amount of fumed silica to the powder containing aspirin will change the antistatic properties of the powder. sex.
Silica can also be used as an absorbent and dispersing agent in the production of western medicine tablets such as vitamin C; in the production of pharmaceutical capsules, adding a small amount of silica can act as a carrier. According to the editor of China Powder Network, Japanese researchers found that adding a small amount of white carbon black to the formula of polyethylene packaging materials can be used to make sterile packaging films for medical articles.

12 Application in ink
Silica is also used to control the flow of printer ink so that it cannot flow or sag at will for clear prints. In beverage cans, it controls the use of high-speed spray coatings. Fumed silica is also used as a dispersant and flow control agent in toner cartridges for copiers and laser printers.

13 Application in pesticides
Silica can be used in herbicides and insecticides in pesticides. Adding small amounts of fumed silica and precipitated silica to a common mixture of two herbicides, dinitroaniline and urea, will prevent the mixture from caking. In granular pesticide formulations, adding a small amount of fumed silica will more effectively control and prevent the production of harmful organisms. Silica can also be used as an absorbent for pollutants in the soil, absorbing pollutants in the soil.

14 Application in daily necessities
Food packaging bags added with white carbon black can keep fruits and vegetables fresh. Silica can also be used as a high-efficiency fungicide for the prevention and treatment of various diseases of fruits; in the production of alcohol, a small amount of silica is added to purify the beer and prolong the fresh-keeping period. In the braid containing vinyl chloride, adding a small amount of fumed silica will change its properties, and the silica acts as a matting agent. It only stays on the surface of the braid without penetrating the braid.
