ZnO Zinc Oixde nanoparticles is a new type of high-functional fine inorganic product of the 21st century. The nano sized zinc oxide produced by Hongwu Nano has a particle size of 20-30nm, due to its finer particle size and large specific surface area, the material has surface effects, small size effects and macroscopic quantum tunneling effects. The nano-level ZNO have special performance in aspects of magnetic, optical, electrical, and sensitive and thus have new applications which general ZNO products cannot match. Below are brief introductions on the applications of nano ZNO in some important fields, showing its attractive and promising prospects.

Hongwu Nano ZNO zinc oxide nanoparticles, size 20-30nm 99.8%, snow white spherical powder for sale.

1. Application in cosmetics — New sunscreens and antibacterial agents

Sunlight includes X-rays, ultraviolet rays, infrared rays, visible light and electromagnetic waves. Appropriate ultraviolet radiation is helpful to human health, but excessive ultraviolet rays can damage the human immune system, accelerate skin aging, and cause various skin problems. In recent years, with the destruction of the atmospheric ozone layer, the intensity of ultraviolet rays reaching the ground has been increasing. The protection of ultraviolet rays has become a very important research topic for personal protection. The band gap of zinc oxide is 3.2eV, and its corresponding absorption wavelength is 388nm, and due to the quantum size effect, the finer the particles, the better it can absorb ultraviolet rays, especially for ultraviolet rays of 280-320nm. Nano particles also have good visible light transmittance. Experiments have shown that nano-ZNO is an ideal ultraviolet shielding agent, so adding nano-ZNO to cosmetics can not only shield ultraviolet rays and sunscreen, but also antibacterial and deodorize, it is really two birds with one stone.

2. Application in textile industry

With the development of science and technology and the improvement of living standards, people are increasingly pursuing high-end, comfortable, and health-care functions. In recent years, various new functional fibers have been continuously developed, such as deodorizing fibers, which can absorb odors and purify air. The anti-ultraviolet fiber, in addition to the function of shielding ultraviolet rays, has the unusual functions of antibacterial, disinfection and deodorization.

3. Self-cleaning ceramics and antibacterial glass

Nano ZNO is widely applied in ceramic industry. Nano ZNO can reduce the sintering temperature of ceramic products by 400-600 degrees Celsius, and the burned products are as bright as a mirror. Ceramic products with nano ZNO have antibacterial, deodorizing and self-cleaning effects of decomposing organic matter, which greatly improves product quality. In addition, the glass with nano ZNO can resist ultraviolet rays, wear resistance, antibacterial and deodorizing, and can be used as automotive glass and architectural glass.

4. Rubber Industry

In the rubber and tire industries, zinc oxide is an essential additive. In the rubber vulcanization process, zinc oxide reacts with organic accelerators, stearic acid, etc to generate zinc stearate, which can enhance the physical properties of vulcanized rubber. It is also used as a vulcanization activator, reinforcing agent and coloring agent for natural rubber, synthetic rubber and latex. Nano ZNO is a raw material for manufacturing high-speed wear-resistant rubber products. It has the advantages of preventing aging, anti-friction and ignition, long service life, and the dosage required is small.

5. Building materials — antibacterial gypsum products

After adding nano-ZNO and metal peroxide particles into gypsum, gypsum products with bright colors and not easy to fade can be obtained, which have excellent antibacterial properties and are suitable for building materials and decorative materials.

6. Coating Industry

In the coating industry, in addition to its tinting power and hiding power, zinc oxide is also an antiseptic and luminescent agent in coatings. It also has excellent anti-aging ability and good antibacterial properties.

7. Gas sensor

Nano ZNO can cause electrical properties—resistance to change with the change of the composition gas in the surrounding atmosphere, so as to detect and quantify the gas. At present, products such as gas alarms and hygrometer sensors that are beneficial to the preparation of nano-zinc oxide resistance changes are on the market. Experiments show that the nano ZNO gas sensor has high sensitivity to C2H2, LPG (liquefied petroleum gas).

8. Image recording materials

Nano ZNO can obtain materials with different properties such as photoconductivity, semiconductor and conductivity according to the preparation conditions. Using this variation, it can be used as an image recording material; it can also be used for electrophotography with its photoconductivity properties; it can be used as a discharge breakdown recording paper by using semiconductor properties; and it can be used as an electrothermal recording paper by using its conductive properties. The advantage is that it has no pollution from three wastes, good picture quality, high-speed recording, can absorb pigments for color copying, and can be used for film printing after acid etching.

9. Piezoelectric materials

Using the piezoelectric properties of nano ZNO, piezoelectric tuning forks, vibrator surface filters, etc. can be made.

10. Catalyst and photocatalyst

Nano ZNO is small in size, large in specific surface area, the bonding state on the surface is different from that in the particle, and the coordination of surface atoms is not complete, which leads to an increase in active sites on the surface and enlarges the reaction contact surface. In recent years, extensive attempts have been made to decompose harmful substances in water with photocatalysts. Important photocatalysts include nano-titanium oxide and zinc oxide. Under ultraviolet light irradiation, Nano ZNO can decompose organic substances, antibacterial and deodorant. This photocatalytic property has been widely used in industries such as fiber, cosmetics, ceramics, environmental engineering, glass and building materials.

11. Phosphors and capacitors

ZnO Zinc Oixde nanoparticles is the only substance that can fluoresce under low-pressure electron rays, and its light color is blue and red. Ceramic powders with ZNO, TIO2, MNO2, etc are sintered into a sheet-like body with a high dielectric constant and a fine and smooth surface, which can be used to manufacture ceramic capacitors.

12. Stealth technology — radar wave absorbing material

Radar wave absorbing materials, referred to as absorbing materials, is a class of functional materials that can effectively absorb incident radar waves and attenuate their scattering. This is of great significance in national defense. Metal oxides such as nano-ZNO have became one of the hot spots in the research of absorbing materials due to their advantages of light weight, thin thickness, light color, and strong absorbing ability.

13. Conductive ZNO material

It is thought that the commonly used conductive particles include metal conductive particles and carbon black conductive particles, and their common disadvantage is that they are all black, which limits the scope of use. Therefore, it is necessary to develop white or light-colored conductive particles to meet the needs of different applications. In recent years, the research of light-colored conductive materials is also one of the hot spots. The conductive ZNO powder is developed for the manufacture of light-colored or white anti-static products, which has great application prospects. Conductive ZNO is mainly used as a conductive white pigment in paint, resin, rubber, fiber, plastic and ceramics. The conductivity of ZNO can impart anti-static properties to plastics and polymers.
