What is the use of nano-zinc oxide? What have been used? Recently, many people have asked about some knowledge about nano-zinc oxide in our official website. Today, we have a simple editor of Jiyuan Lutai Nano to give you a simple I would like to introduce some knowledge about this and hope to be helpful to everyone.
1. Adding nano zinc oxide to feed can increase biological activity
Due to its small particle size, nano-zinc oxide can penetrate the interstitial space, can also pass through the smallest capillaries of the body, and has a wide distribution in the body, which can greatly improve the bioavailability of feed ingredients. Compared to other zinc sources, nano zinc oxide has a more efficient biological activity.
2, the addition of nano zinc oxide in the feed can increase the absorption rate
Since the particle size of the nano zinc oxide is very fine, when the particle size is reduced, the number of surface atoms is rapidly increased, thereby increasing the surface area exposed to the medium and improving the absorption efficiency of the animal. Studies have shown that 100 nm particles are 10-250 times more absorptive than other large particles.
3, the addition of nano zinc oxide in the feed can increase the antioxidant performance
Because nano zinc oxide has strong chemical activity, it can oxidize with many organic substances, including organic matter in bacteria, and kill most bacteria and viruses. The main mechanism of action is that nano-zinc oxide can generate conduction band electrons and valence band holes under illumination conditions, and can react with H2O or OH- ions adsorbed on the surface to form hydroxyl groups with strong oxidative properties, thereby killing cells. The relevant tests showed that when the concentration of nano zinc oxide was 1%, the bactericidal rate against S. aureus was 98.86% within 5 min, and the bactericidal rate against E. coli was 99.93%.
The use of traditional methods to produce zinc oxide requires the use of acid and alkali, and the company uses the filter cake slurry (basic zinc carbonate) as raw material, after drying, dispersion, calcination to obtain zinc oxide with a particle size below 20 nm. The selected raw materials of this process are single, acid-free, alkali-free and impurity-free, and the intermediate products do not need to be washed or discharged.
It is reported that nano zinc oxide is a cutting-edge new material for the support and development of the national “Twelfth Five-Year Plan”. What is the concept of 20 nanometers? Liu Hongbiao made a metaphor: equivalent to one thousandth of a hair. Compared with traditional zinc oxide products, nano-zinc oxide has a small particle size close to the gaseous state and has unique magnetic, optical and electrical properties, so it has important application value and broad market space in many fields.
Nano-ZnO (ZnO) has many excellent properties and is widely used in many aspects. However, due to the polarity and fineness of the inorganic nanomaterial itself, it has a large specific surface area and a high specific surface area. Can make them difficult to disperse in non-polar media. It is easy to agglomerate in polar media, which directly affects its performance. As a result, the properties of the nanoparticles are lost in the final use. Moreover, since they are inorganic substances, the affinity with organic substances is poor, which leads to practical application of nano zinc oxide (ZnO) in high polymer fibers, and thus in the development of nano zinc oxide (ZnO). This critical bottleneck must be addressed.
