Zinc oxide's application
Publish Time: 2022-02-16 Origin: Site
Zinc oxide has a large band gap and exciton binding energy, high transparency, excellent luminescence performance at room temperature, and has been used in the semiconductor field of LIQUID crystal display, thin film transistors, light-emitting diodes and other products. In addition, as a kind of nanomaterial, microgranular zinc oxide has also begun to play a role in related fields.
The use of zinc oxide
Zinc oxide is a common chemical additive, widely used in plastics, silicate products, synthetic rubber, lubricating oil, paint coating, ointment, adhesive, food, battery, flame retardant and other products in the production.
1. Can be used as natural rubber, synthetic rubber and latex sulfide active agent, reinforcing agent and colorant. Nano zinc oxide can enhance the physical properties of vulcanized rubber because of its fine particle size and large specific surface area.
2. Can be used as catalyst, desulfurization agent. The high surface activity of zno nanoparticles can improve the selectivity and catalytic efficiency of catalysts.
3. Can be used as coating filler preservatives and luminescent agent. Nano zinc oxide excellent uv shielding ability, in addition to the above performance, so that it has more outstanding properties in coatings such as anti-aging.
4. Can be used as a flux of glass and ceramics. Nano zinc oxide can reduce the sintering temperature of glass and ceramics due to its fine particle size and high activity. In addition, the ceramic glaze prepared by nano zinc oxide is more smooth, and has antibacterial, mildew, deodorization and other effects.
5. In the electronic industry is the main material of varistor, is also the main additive of magnetic, optical and other materials. Nano zinc oxide is used to prepare varistors, which not only has lower sintering temperature, but also improves the properties of varistors, such as flow capacity and nonlinear coefficient. The application of nanometer zinc oxide in optical devices will make a great breakthrough with the further study of the optical properties of nanometer zinc oxide. In addition, it can also be used as a dyeing agent in the printing and dyeing industry.
