Its unique flaky nanostructure endows it with excellent ultraviolet shielding performance and antibacterial activity. The large specific surface area improves the adsorption capacity and reaction activity of the material. Its good water-based dispersion performance allows it to be easily integrated into water-based coatings and cosmetic formulas without agglomeration. High purity ensures the safety of the product in high-end application scenarios. It can endow composite materials with long-lasting antibacterial performance, and has good biocompatibility, making it suitable for personal care products. The production process adopts vapor deposition method to ensure the uniformity and controllability of nano-particles.
The product has an average particle size of 30±5 nm, specific surface area of 85±5 m²/g, minimum purity of 99.5%, zinc content of 59.0% minimum, moisture content not exceeding 0.1%, lead content ≤3 ppm, arsenic content ≤1 ppm, cadmium content ≤0.5 ppm, and appears as white ultra-fine powder that can be dispersed in water, ethanol and other solvents. It is packaged in 5kg vacuum sealed cartons, stored in a cool and dry environment, and has a shelf life of 1 year.
It is used to prepare antibacterial plastics and antibacterial fibers to improve the antibacterial时效 of products; as an ultraviolet shielding agent for sunscreen cosmetics, replacing traditional organic sunscreens to reduce skin irritation risk; as a functional coating additive to improve the aging resistance and antibacterial performance of the coating; and as a modifier for lithium battery anode materials to improve the cycle life of batteries.
