About  Zinc Nanoparticles, Nano Zn Pulver  :

Small particle size, large specific surface area: The particle size of nanometer zinc powder is minimal, usually at the nanometer level, so its particular surface area is relatively large. This structure makes the nano-zinc powder have higher reactivity and faster reaction speed.

Nanometer zinc powder has excellent mechanical properties due to its size effect and quantum effect. Its hardness, strength and wear resistance are much higher than the conventional zinc material.

Good optical performance: nanometer zinc powder has good reflection and scattering versions of light and can manufacture materials and devices with high reflectivity and ultraviolet resistance.

High chemical reactivity: nanometer zinc powder has high chemical reactivity and can chemically react with other metals or non-metallic elements to generate new substances. This property makes it an ideal catalyst or reactant in many chemical reactions.

Good electrical properties: nanometer zinc powder has good electrical conductivity and electromagnetic properties, which can be used to manufacture electronic components and electromagnetic devices.

Physical method

The physical method is standard for preparing nanometer zinc powder, including mechanical ball milling, vacuum evaporation, and laser pulse methods.

Mechanical ball milling method: The automated mixing and grinding of zinc powder through a ball mill. In the ball milling process, zinc atoms are gradually refined to the nanometer level by the impact and friction of the spheres. The advantages of this method are a simple preparation process and low cost, but the disadvantages are wide particle size distribution and agglomeration phenomenon of prepared nano-zinc powder.

Vacuum evaporation method: It evaporates zinc materials by heating them in a vacuum environment. Zinc atoms evaporate from the surface and condense into nanoscale zinc particles in a vacuum during evaporation. The advantages of this method are high purity and uniform particle size, but the disadvantages are high equipment cost and low yield.

Laser pulse method: Laser pulse method is a method that uses laser pulses to irradiate the surface of zinc materials. During the pulse irradiation, zinc atoms absorb the laser energy and splash out from the surface, then condense into nanoscale zinc particles in a vacuum. The advantages of this method are high purity and uniform particle size, but the disadvantages are high equipment cost and low yield.

Chemical law

The chemical method is standard for preparing nanometer zinc powder, including chemical vapor deposition, solution method, etc.

Chemical vapor deposition is a method of reacting the surface of zinc with gaseous zinc-containing compounds at high temperatures. During the reaction, the zinc-containing combination breaks down and releases zinc atoms, which are then deposited on the surface of the zinc material to form nanoscale zinc particles. The advantages of this method are high purity and uniform particle size, but the disadvantages are high equipment cost and harsh process conditions.

Solution method: The solution method dissolves zinc salts and adjusts the pH value of the solution so that zinc ions precipitate and form nanoscale zinc particles. The advantages of this method are that the preparation process is simple, the cost is low, and the particle size and shape of nanometer zinc powder can be controlled by choosing different solutions and reaction conditions. However, the disadvantage is that there may be interference from other ions, affecting the performance of nanometer zinc powder.

Biological law

The biological method is a new method for preparing nanometer zinc powder, mainly including microbial synthesis and plant extraction.

Microbial synthesis method: Microbial synthesis method uses microbial strains as catalysts to reduce zinc ions into nanoscale zinc particles. The advantages of this method are that the preparation process is simple, the cost is low, and the size and shape of nano-zinc particles can be controlled by selecting different microbial strains. However, the disadvantage is that the growth and reproduction of microbial strains may affect the performance of nano-zinc particles.

Plant extraction method: Plant extraction method is a method that uses the active ingredients in plant extracts to react with zinc ions to generate nanoscale zinc particles. The advantages of this method are that the preparation process is simple, the cost is low, and the particle size and shape of nano-zinc particles can be controlled by selecting different plant extracts. However, the disadvantage is that other components in plant extracts may affect the performance of nano-zinc particles, which requires in-depth research and screening.
