rubber industry
It has large specific surface area and strong activity, and can be used as functional additives such as vulcanization activator to improve the smoothness, wear resistance, mechanical strength and aging resistance of rubber products, reduce the consumption of common zinc oxide and prolong the service life;
ceramic industry
As glaze and flux of milk porcelain, it can reduce sintering temperature, improve luster and flexibility, and has excellent performance;
power electronics
The nonlinear characteristics of nano-zinc oxide varistor make it play the role of overvoltage protection, lightning protection and instantaneous pulse, and become the most widely used varistor material. It is proved that the nonlinear coefficient α=45, the critical electric field value is greater than 1000V, and the leakage current is less than1μ a. ..
Defense industry
Nano-zinc oxide has a strong ability to absorb infrared rays, and the ratio of absorption rate to heat capacity is large, so it can be used in infrared detectors and infrared sensors. Nano-zinc oxide also has the characteristics of light weight, light color and strong wave-absorbing ability, which can effectively absorb radar waves and attenuate them, and is applied to new wave-absorbing stealth materials;
textile industry
It has good ultraviolet shielding and excellent antibacterial and bacteriostatic properties. Adding it to the fabric can give the fabric the functions of sun protection, antibacterial and deodorization.
Feed industry
As a nano-material, nano-zinc oxide has the characteristics of high biological activity, high absorption rate, strong oxidation resistance, safety and stability, and is the most ideal zinc source at present. Using nano-zinc oxide to replace high zinc in feed not only solves the demand of animals for zinc, but also reduces the pollution to the environment. The use of nano-zinc oxide can play an antibacterial and bacteriostatic role, and at the same time improve animal production performance;
Coatings and other fields
Metal oxide powders, such as zinc oxide, titanium dioxide, silicon dioxide, aluminum oxide and magnesium oxide, are made into nanoscale. Because the particle size is equal to or smaller than light wave, the gap between conduction band and valence band increases due to the size effect, so the light absorption is significantly enhanced. Various powders have different shielding and reflection efficiencies for light. Compared with zinc oxide and titanium dioxide, the shielding efficiency is similar when the wavelength is less than 350 nm (UVB), but the shielding efficiency of zinc oxide is obviously higher than that of titanium dioxide at 350 ~ 400 nm (UVA). At the same time, the refractive index of zinc oxide (n= 1.9) is lower than that of titanium dioxide (n=2.6), which makes the fiber transparent and beneficial to textile dyeing.
Nano-zinc oxide can also be used to make far-infrared reflective fiber materials, commonly known as far-infrared ceramic powder. This far infrared ray reflecting fiber absorbs the heat emitted by human body and radiates far infrared rays within a certain wavelength range to human body, which can not only increase the blood flow of subcutaneous tissue of human body and promote blood circulation, but also shield infrared rays and reduce heat loss. Therefore, compared with ordinary fibers, this fiber has the function of storing heat and keeping warm.
