Nano zinc oxide (ZnO) with a particle size between 1-100 nm is a high-end, high-performance, and fine inorganic product that exhibits many special properties, such as non mobility, fluorescence, piezoelectricity, absorption and scattering of ultraviolet radiation. By utilizing its wonderful properties in light, electricity, magnetism, sensitivity, etc., it can be used to manufacture gas sensors, phosphors, rheostats, UV shielding materials, image recording materials, piezoelectric materials, varistors, high-efficiency catalysts, magnetic materials, and plastic films. Many people cannot see the excellent characteristics of nanomaterials due to their microscopic changes. Through practice, nano zinc oxide is now widely used in various fields such as rubber due to its excellent properties.

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 nano zinc oxide varistors enable them to provide overvoltage protection, lightning resistance, and instantaneous pulse protection, making them the most widely used varistor material. Research has shown that the nonlinear coefficient α of the nano zinc oxide varistor for lightning arresters is 45, the critical electric field value is greater than 1000V, and the leakage current is less than 1 μ A.

defense industry

Nano zinc oxide has a strong ability to absorb infrared radiation, with a high 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. It can effectively absorb radar waves and attenuate them, and is applied in new types of absorbing stealth materials;

Since the discovery of carbon nanotubes in 1991, low dimensional nanomaterials such as linear, strip-shaped, rod-shaped, and tubular have attracted much attention due to their unique properties and potential applications in nanodevices. Zinc oxide (ZnO) is an important optoelectronic semiconductor material with a wide bandgap (3137eV) and a large exciton binding energy (60meV) at room temperature. It is widely used in photodiodes, sensors, varistors, and photodetectors, especially in the discovery of room temperature ultraviolet light emission phenomena in ZnO nanostructures, making ZnO once again a focus of research in short wave semiconductor laser device materials.

textile industry

It has good UV shielding and superior antibacterial and bacteriostatic properties. When added to fabrics, it can endow them with functions such as sun protection, antibacterial, and deodorization;

feed industry

Nano zinc oxide, as a type of nanomaterial, has high biological activity, high absorption rate, strong antioxidant capacity, safety and stability, and is currently the most ideal source of zinc. Replacing high zinc with nano zinc oxide in feed can not only meet the animal's demand for zinc, but also reduce environmental pollution. The use of nano zinc oxide can have antibacterial and bacteriostatic effects, while improving animal production performance;

Coatings and other fields

When metal oxide powders such as zinc oxide, titanium dioxide, silicon dioxide, aluminum oxide, and magnesium oxide are made into nanoscale particles, the size effect increases the gap between the conduction and valence bands due to the particle size being comparable to or smaller than the light wave, resulting in significantly enhanced light absorption. Various powders have different levels of shading and reflection efficiency towards light. When comparing zinc oxide and titanium dioxide, the shielding efficiency of the two is similar when the wavelength is less than 350 nanometers (UVB), but the shielding efficiency of zinc oxide is significantly higher than that of titanium dioxide when the wavelength is between 350-400nm (UVA). At the same time, the refractive index of zinc oxide (n=1.9) is lower than that of titanium dioxide (n=2.6), resulting in lower diffuse reflectance of light and higher fiber transparency, which is beneficial for textile dyeing.

Nano zinc oxide can also be used to manufacture materials for far-infrared reflective fibers, commonly known as far-infrared ceramic powder. And this type of far-infrared reflective fiber absorbs the heat emitted by the human body and radiates a certain wavelength range of far-infrared radiation to the human body. In addition to increasing blood flow in the subcutaneous tissue of the human body and promoting blood circulation, it can also block infrared radiation and reduce heat loss. Therefore, the fiber is more effective in heat storage and insulation than ordinary fibers.
