Zinc Nanoparticles Nano Zn Powder CAS 7440-66-6

About Zinc Nanoparticles Nano Zn Powder:
Nano-zinc is a kind of polycrystal, and the diameter of each grain is on the order of a nanometer. The grain itself is long-range ordered, while the interface of the grain is neither long-range ordered nor short-range ordered. The structural characteristics of nano-zinc make it have very different properties from traditional materials. Lead-zinc ore processing has broad application prospects in magnetic materials, electronic materials, optical materials, high strength, high-density materials, catalysts, sensors and other aspects, so more and more people pay attention to it.
Nanometer zinc powder is insoluble in water, soluble in acid and alkali, slowly soluble in acetic acid, ammonia water. It is highly reductive and reacts with acid and base to produce hydrogen. Damp caking, stable in dry air, wet air to generate white basic carbonate and covered on the surface. A blue-green flame is burned in the air to form zinc oxide. High purity reacts slowly with sulfuric acid and nitric acid but accelerates when there are small amounts of other metals such as steel, tin, and lead.
Nanometer zinc is regular spherical, the surface oxidation is less, the spherulite surface is smooth and clean, the melting deformation and adhesion into grape-like, plate-like particles are very few, good dispersion, uniform particle size, is conducive to the production of high-quality anticorrosive coating; The specific surface area of nano zinc is large, the proportion of loose packing is small, the coating covering efficiency is high, and the chemical reduction effect is good.

How is Zinc Nanoparticles Nano Zn Powder Produced?
How do you make zinc nanoparticles? ZnO nanoparticles were synthesized by the direct precipitation method using zinc nitrate and KOH as precursors. In this work, the aqueous solution (0.2 M) of zinc nitrate (Zn(NO3)2.6H2O) and the solution (0.4 M) of KOH were prepared with deionized water. Another way to prepare nano-sized zinc is Zinc nanoparticles were prepared by rolling vibration grinding with commercial zinc powder at room temperature in a dry process. After 11h grinding, it was found that zinc nanoparticles had good dispersion and uniform particle size. The zinc nanoparticles were used in the process of hydrogen production, and argon gas was used as a carrier gas to carry water vapor into the reactor, where it contacted with the preheated zinc nanoparticles and decompose to generate hydrogen and zinc oxide nanostructures. The concentration of hydrogen in the product was measured by gas chromatography, and the solid product was characterized as a mixed rod-like and block-like zinc oxide nanostructure by energy emission spectroscopy and transmission electron microscopy. It has been proved that the solid product has excellent light absorption in the visible region.
 
Applications of Zinc Nanoparticles Nano Zn Powder :
As a new material, metallic zinc nanoparticles have shown many unique properties in the chemical industry, optics, electricity and biomedicine. Can Nano Zinc kill bacteria? The bactericidal activity of ZnO nanoparticles was also compared with the conventional disinfection methods such as chlorine and UV disinfection. According to the results, ZnO had antibacterial activity against some wastewater bacteria and had the most effective against Gram-positive bacteria S.
 As a high-efficiency catalyst, zinc and its alloy nano-powders can be used as catalysts in the synthesis of methanol from carbon dioxide and hydrogen due to their high efficiency and high selectivity.
Rubber field
Is nanometer zinc sulfide agent in the rubber industry, than ordinary zinc powder dispersion is excellent, can improve the thermal conductivity of rubber products, wear-resisting, tensile properties, main applications of natural rubber, butyl benzene rubber, polybutadiene rubber, nitrile rubber, ethylene-propylene rubber, butyl rubber and other rubber products, especially for nitrile rubber and PVC foam rubber superior performance in the industry?
Other uses
Due to its characteristics of nanomaterials, the application of nanomaterials has been expanded to the plastic industry, sunscreen cosmetics, special ceramic products, adhesives, special functional paints and coatings, as well as chemical fiber, textile and health processing to make special fiber products such as ultraviolet protection, deodorization, sterilization and bacteriostatic.

 

Storage Condition of Zinc Nanoparticles Nano Zn Powder:
The damp reunion will affect zinc nanoparticles dispersion performance and using effects, therefore, nano Zn powder should be sealed in vacuum packing and stored in the cool and dry room, the nickel nanoparticles can not be exposure to air. In addition, the Zn Nanoparticles should be avoided under stress.

Packing & Shipping of Zinc Nanoparticles Nano Zn Powder:
We have many different kinds of packing which depend on the zinc nanoparticles quantity.
Zinc nanoparticles packing: vacuum packing, 1kg/bag, 25kg/barrel, or as your request.
Zinc nanoparticles shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
