In feed, silicon dioxide primarily serves as an anticaking agent, flowability enhancer, and nutrient carrier, used in premixes, vitamin products, and trace mineral additives. Its specific functions can be divided into three aspects:
 

I. Improving Physical Properties
Anticaking and Flowability Optimization

By absorbing moisture and humidity from the feed, it prevents caking caused by dampness or pressure, maintaining the loose state of powdered feed.
As a flow aid, it improves the free flowability of powdered additives such as mineral premixes and vitamin premixes, simplifying the processing and improving production efficiency.
Enhanced Stability

Absorption of oxygen and moisture can slow down feed spoilage and extend shelf life, such as in the application of flavorings and mold inhibitors.


II. Functional Applications
Nutrient Carrier and Controlled Release
As a carrier for premixes, it adsorbs vitamins, antioxidants, and other nutrients, achieving even distribution.
Controlled Release: In vitamin products (such as silicon-type choline chloride and allicin), it adsorbs the active ingredient and releases it slowly, improving utilization efficiency.

How does the addition of nano-silica affect the performance of rubber?

When the amount of nano-silica added is low, the tensile strength of the rubber usually increases with the increase of the amount added. This is because nano-silica can act as a reinforcing agent, forming physical or chemical adsorption with rubber molecular chains. For example, in natural rubber, when the amount of nano-silica added increases from 0 to 5 phr (parts per hundred rubber), the tensile strength may gradually increase. The reason is that nano-silica particles interact with rubber molecular chains, and can effectively transfer and disperse stress during stretching, preventing the slippage of rubber molecular chains, thus improving tensile strength.
