Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. It is insoluble in water but soluble in acids and strong bases. Zinc oxide is a commonly used chemical additive and is widely applied in the production of plastics, silicate products, synthetic rubber, lubricating oils, paints and coatings, ointments, adhesives, food, batteries, flame retardants and other products. Zinc oxide has a large band gap and exciton binding energy, high transparency, and excellent room-temperature luminescence performance. It is widely used in products such as liquid crystal displays, thin-film transistors, and light-emitting diodes in the semiconductor field. In addition, micro-particle zinc oxide, as a nanomaterial, has also begun to play a role in related fields.

Product application:
Zinc oxide, as a multifunctional compound, plays a significant role in multiple industries. The following are the main functions and applications of zinc oxide:
1.The functions and applications of industrial zinc oxide
The coatings industry: Zinc oxide is one of the important raw materials for manufacturing various coatings, such as paints, inks and plastic coatings, etc. It has good heat resistance and gloss, and can enhance the hardness and wear resistance of the coating.
In the cosmetics industry, zinc oxide is widely used as a key ingredient in sunscreens and concealers. It can absorb ultraviolet rays and reflect light, protect the skin from damage, and at the same time cover facial blemishes.
In the glass industry, zinc oxide is used in the glass production process to adjust the transparency and color of the glass. It can increase the refractive index and dispersion coefficient of glass, making the glass present different colors and textures.
In the electronics industry, zinc oxide is used as a semiconductor material and insulator material because of its excellent electrical properties, low electrical conductivity and poor conductivity.
In the fertilizer industry, zinc oxide can be used to prepare fertilizers because it can promote plant growth and enhance the soil's water retention capacity.
Medical and health care: Industrial zinc oxide can be used in the treatment of dermatitis, promoting wound healing, corneal ulcer treatment, vitamin A deficiency treatment, psoriasis treatment, etc.
2.The Functions and Applications of Nano Zinc Oxide
In the chemical industry, zinc oxide is widely used as a catalyst and desulfurizer. For instance, it serves as a catalyst in the synthesis of methanol and as a desulfurizer in the synthesis of ammonia. The high surface activity of nano-zinc oxide can enhance the selectivity and catalytic efficiency of catalysts, and it has a broad potential application market.
In the coatings industry, zinc oxide not only has tinting power and covering power, but also serves as a preservative and brightener in coatings. In addition, the excellent ultraviolet shielding ability of nano zinc oxide makes it have more prominent characteristics in terms of anti-aging and other aspects of coatings.
In the medical and health care and food industries, zinc oxide has the functions of detoxification, hemostasis, muscle growth and astringency. It is also used as a raw material for adhesive plasters and is helpful for promoting children's intellectual development. The demand for nano zinc oxide in the food hygiene industry is gradually expanding, but the product requirements are also relatively strict, especially regarding the content of harmful heavy metal elements.
Glass industry: In the glass industry, zinc oxide is used in special glass products. In the ceramic industry, zinc oxide is used as a flux. In the dyeing and printing industry, zinc oxide is used as an anti-dyeing agent. Due to its fine particles and high activity, nano zinc oxide can lower the sintering temperature of glass and ceramics. In addition, the glaze surface of ceramics prepared with nano zinc oxide is smoother, and it also has the functions of antibacterial, anti-enzyme and deodorization.
Rubber industry: In the rubber industry, during the rubber vulcanization process of lead-zinc mining equipment, zinc oxide can improve the physical properties of vulcanized rubber, enhance the activity of accelerators, shorten the vulcanization time, and improve the wear resistance and tensile mechanical properties of rubber. Secondly, it can be used as a reinforcing agent and colorant for rubber, and also as a vulcanizing agent for chloroprene rubber and a compounding agent to enhance thermal conductivity.
In the paint and coating industry, zinc oxide is mainly applied for its tinting strength, covering power, as well as anti-corrosion and luminescence functions. It is commonly used in the production of white paint and enamel. Zinc oxide is slightly alkaline and can react with trace amounts of free fatty acids to form zinc soaps, making the paint film flexible, firm and preventing metal oxidation, etc.
