Application of zinc oxide in industrial fields
1. Paint: Zinc oxide can improve the hiding power and durability of paint, making the paint coating stronger and more wear-resistant, so it is widely used in anti-corrosion coatings, automotive paints, etc.
2. Rubber: Zinc oxide can be used as a rubber additive to increase the strength and hardness of rubber, making it more resistant to aging, so it is widely used in tires, rubber tubes, etc.
3. Plastics: Zinc oxide can be used as a plastic stabilizer to prevent plastic aging and increase its durability and reliability, so it is widely used in wires, cables and other fields.
Application of zinc oxide in cosmetics
1. Sun protection: Zinc oxide can absorb ultraviolet rays and protect the skin, so it is widely used in sunscreen, lipstick, foundation and other products.
2. Antibacterial: Zinc oxide has antibacterial effects and can be used in skin care products such as facial masks and cleansing products.
3. Promote tissue healing: Zinc oxide can promote the healing of skin wounds and has a repairing effect, so it is widely used in products such as Band-Aids and hand creams.
Characteristics of zinc oxide
1.High chemical stability: able to remain stable in harsh environments such as high temperature, high pressure, strong acid, strong alkali, etc.
2.Good electrical conductivity: suitable for electronics, communications, electricity and other fields.
3.Unique physical properties: high refractive index, low dielectric constant, high light transmittance, etc.
4.Environmentally friendly and non-toxic: harmless to the human body and the environment.
5.Skin protection: has anti-inflammatory, antibacterial, wound healing and sun protection effects.
Advantages
Broad Application Fields: Suitable for plastics, silicate products, synthetic rubber, lubricating oils, paints and coatings, ointments, adhesives, foods, batteries, flame retardants, and many other products.
Excellent Luminescent Properties: Applied in semiconductor products such as liquid crystal displays (LCDs), thin-film transistors (TFTs), and light-emitting diodes (LEDs).
Effective Sunscreen Agent: Capable of absorbing ultraviolet (UV) radiation, providing broad-spectrum UV protection (both UVA and UVB).
Theory
Zinc oxide belongs to the N-type semiconductor category, exhibiting excellent luminescent properties at room temperature. It has a large energy band gap and exciton binding energy, resulting in high transparency. The principle of zinc oxide absorbing UV radiation is that electrons in the valence band can absorb energy from UV radiation and undergo transitions. The function of scattering UV radiation is related to the particle size of the material, with nanoscale particles offering significant advantages.
