Zinc oxide modification is a process of modifying zinc oxide by physical or chemical methods to change its morphology or properties, thereby giving it new properties or improving its original properties.

Modification purpose:1.Improve performance：Through modification, the dispersion, stability, bioavailability and other properties of zinc oxide can be improved.;2.Cost reduction：Modified zinc oxide can replace more expensive materials in some applications, thereby reducing production costs;3.Expand the application field：The modified zinc oxide can have new functional properties, thus expanding its application fields.

modified method：

1.Nanotechnology is an effective method of zinc oxide modification. By nanosizing, the particle size of zinc oxide can be significantly reduced1~100 nm range. Nano zinc oxide has a high surface area to volume ratio, as well as unique chemical and physical properties, such as high absorption rate, high permeability, strong biological activity, etc.

2.Porous technology can make zinc oxide molecules have high porosity and form a microporous structure, thereby significantly increasing its specific surface area. This microporous structure enhances the contact of zinc oxide with intestinal microorganisms and improves its antibacterial activity.

3.Surface coating modification is another commonly used method of zinc oxide modification by coating the surface of zinc oxide particles with one or more layers of substances.(such as inorganic, organic, polymer, etc.), can change its surface properties, improve its dispersion, stability and bioavailability. Surface coating modification can also give zinc oxide new functional properties, such as antibacterial, anti-oxidation, anti-ultraviolet and so on.

Surface coating modification In industrial mass production, continuous modification equipment is commonly used."Honeycomb mill" for processing,Honeycomb grinding has the characteristics of compact structure, small size, simple operation, stable operation, low labor intensity and low noise. The honeycomb mill modification process is an air sweeping system. Talcum powder is transported to the mixing modification cavity through air flow for modification. The entire mixing modification cavity is a cylindrical structure without any dead ends. When the amount of modifier is the amount of modified powder.When 0.8%~ 1.2%, the activation rate can reach more than 99%. Through the formation of chemical bonds or physical winding, the surface modifier and dispersant and ultrafine powder form a strong chemical bond coupling or mechanical physical winding; by accurately calculating the amount of modifier and excess coefficient, basically can form a single molecular coating film, in order to complete the modification treatment.

modification effect：1.Increased bioavailability：The bioavailability of modified zinc oxide is significantly improved due to the reduction of particle size and the increase of specific surface area.;2.Enhanced antibacterial effect：Porous zinc oxide and zinc oxide coated with antibacterial substances can significantly enhance its antibacterial effect;3.Improve application performance：The application performance of the modified zinc oxide in the field of adhesives, ink coatings, glass ceramics and other fields has been significantly improved.

Application areas：1.feed additive：Modified zinc oxide as a feed additive can significantly improve animal growth performance and intestinal health.2.Materials Science：Modified zinc oxide has a wide range of applications in rubber, plastics, coatings and other fields.3.medical field：Modified zinc oxide can be used as a drug carrier, such as antibacterial agent, and has potential application value in the field of medicine.
