Nano zinc oxide (ZnO), white Hexagonal crystal family crystal or spherical particles, particle size is less than 100nm, average particle size is 50nm, and specific surface area is more than 4m2/g. It has extremely high chemical activity, excellent catalytic and photocatalytic activity, and has anti infrared, ultraviolet radiation, and bactericidal functions. Good liquidity.
Used as a catalytic material and semiconductor material for photochemistry, it can catalyze the photolysis of organic molecules. ZnO at 10-25nm can be used for the catalytic photolysis of phenol and as a catalyst for the direct synthesis of methanol through CO hydrogenation. Compared with ordinary ZnO, it can significantly improve the CO conversion rate and methanol recovery rate. Used for manufacturing fibers with anti ultraviolet and anti infrared radiation functions, as well as manufacturing synthetic rubber, coatings, etc.
rubber industry
With large specific surface area and stronger activity, it can be used as a functional additive such as vulcanizing activator to improve the smoothness, wear resistance, mechanical strength and anti-aging performance indicators of rubber products, reduce the use of ordinary zinc oxide, and extend the service life;
Ceramic industry
As a milk porcelain glaze and flux, it can reduce sintering temperature, improve glossiness and flexibility, and has excellent performance;
power electronics
The nonlinear characteristics of nanometer zinc oxide Varistor enable it to play the role of overvoltage protection, lightning protection and instant pulse, and become the most widely used varistor material. The research proves that the nonlinear coefficient of nanometer zinc oxide Varistor for lightning arrester α= 45, critical electric field value greater than 1000V, leakage current less than 1 μ A.
Arms industry
Nano zinc oxide has a strong ability to absorb infrared radiation, with a large ratio of absorption rate to heat capacity, and can be applied to infrared detectors and sensors; Nano zinc oxide also has the characteristics of light weight, light color, and strong absorption ability, which can effectively absorb radar waves and attenuate them, and is applied to new types of absorbing stealth materials;
Since the discovery of carbon nanotubes in 1991, low dimensional nanomaterials (such as linear, banded, rod-shaped, and tubular) have attracted great attention due to their unique properties and potential applications in nanodevices. Zinc oxide (ZnO) is an important photoelectric semiconductor material with wide band gap (3137eV) and large exciton binding energy (60meV) at room temperature. It is widely used in photodiodes, sensors, Varistor and photodetectors, especially the discovery of room temperature ultraviolet light emission of ZnO nanostructures, which makes ZnO once again become a research point of short wave semiconductor laser device materials.
Textile manufacturing
It has good UV shielding and superior antibacterial and antibacterial properties. When added to the fabric, it can endow it with functions such as sun protection, antibacterial, and deodorization;
Feed industry
Nano zinc oxide, as a nanomaterial, has high biological activity, high absorption rate, strong antioxidant ability, safety and stability, and is currently the most ideal zinc source. Replacing high zinc with nano zinc oxide in feed can not only meet the demand for zinc in animals, but also reduce environmental pollution. The use of nano zinc oxide can have antibacterial and antibacterial effects, while improving animal production performance.
