Magnetic Materials Superfine 20nm Nano Iron （Fe）Powders

Iron nanopowder has high SSA and high reactivity, fast degradation rate of pollutants 

The nano-iron powder should be sealed and stored in a dry, cool environment, and packaged for inert gas protection or vacuum packaging.

Hongwu High active iron nanoparticles(20nm-100nm) is widely used in absorbing materials.

Iron nanopowders is high active, do oxygen passivated on the surface, good spherical shape.

High-performance magnetic materials Nano Iron Powder in 20nm, 40nm, 70nm, 100nm,99.9% with high quality.

As nano iron particle active is very high, generally we supply in wet powder form, particle size has 20nm, 40nm, 70nm, 100nm.99.9%

For safety ship HW NANO supply 20nm 40nm 70nm iron nano dispersion liquid with Volume pricing.

Zero-valent nano iron magnetic powder for wastewater/sewage treatment     Hongwu International Group Ltd offer a highly diverse range of powder grades with average grain sizes from approx. 20nm to 150nm. We provide technical support in the selection of the powders suitable for specific applications and for questions regarding process optimization.     Zero-valent nano iron powder have certain magnetic, and under the action of magnetic field can be separated easily and quickly from the wastewater solution, can effectively remove chlorinated hydrocarbon, diphenyl ether, aromatic nitro and polycyclic aromatic hydrocarbons fluorene, etc.  The decontamination mechanism of nano iron: 1. The reduction of nano iron     the iron is active metal with reducing power, thus it can directly reduce dye into amino organic matterin in the partial acid aqueous.Because amino organic color looks light, and easy to be oxidized decomposition, so the chroma of wastewater can be reduced. Some heavy metal ions in the wastewater can be reduced by iron. 2. Micro electrolysis     Iron has electrochemical properties. Its electrode reaction product the new ecological [H] and fe2+ can make the oxidizing reduction with many components in wastewater, dyeing assistant agent can be damaged, broken, loss auxochromic ability; It can make the macromolecular material decompose into small molecule intermediates, and make some difficult biochemical degradation of chemical material become handle easily to improve the water biological properties. 3. The coagulation adsorption     Under the condition of partial acid wastewater it will produce large amounts of Fe2+ and Fe3+, when the PH value to alkaline and aerobic,ferric hydroxide hydrogen and ferrous hydroxide floc form, iron hydroxide hydrolysis could also generate ferrous hydroxide complex ion, which all have very strong flocculation performance, so original suspended solids in the waste water, and insoluble substances produced by micro electrolysis and chromaticity of insoluble substance can be adsorption condensation, hence the wastewater got the purification.     Thus, Zero-valent nano iron powder processing wastewater a comprehensive effect of reduction, micro electrolysis, coagulation adsorption.

zero valent iron nanopowder ( ZVI ) is element metal Fe nanopowder. HW have 20nm, 40nm, 70nm, 100nm at offer

HWNANOMATERIAL is supplying pure phrase M VO2 vanadium oxide nanoparticles, contact us for detailed product data.

Silicon nitride submicron powder, widely used as insulator or chemical barrier. 

Anatase Nano TIO2, Nano titanium oxide, rutile nano titanium dioxide         Nano titanium oxide, also known as titanium white powder is a kind of loose powder. The role of strong ultraviolet shielding, good dispersion and weather resistance make it become an important nano material. TiO2 nanopowder can be used in cosmetics, functional fibers, plastics, coatings, paints and other fields, as UV shielding agent to prevent UV damage. Besides, nano titanium dioxide can also be used for high-grade automotive topcoat with the corner effect of color. HW nano material titanium dioxide spec: T681, Anatase, 10nm, 99.9% T685, Anatase, 30-50nm, 99.9% T689, Rutile, 30-50nm, hydrophilic and hydrophobic You can choose the most suiltable one for your application.         With the accelerated development of the economy, the indoor decoration materials and daily chemicals used in urban life have seriously polluted the indoor air quality and affected people's normal life. Indoor air pollution has aroused widespread attention, the city's main pollutant is from building decoration materials released formaldehyde, toluene and other organic substances, the current for these pollutants have not yet effective treatment. Nano Titanium oxide can be irradiated in the light of these harmful substances can be decomposed into carbon dioxide and water to achieve the purpose of indoor air purification.         Now the development of industry, the atmosphere was suffered a large degree of pollution. Industrial production of nitrogen oxides, sulfides, organic small molecules and automotive, motorcycle exhaust, a serious impact on the environment of human life, so that people's health has been greatly affected. Therefore, using nano titanium dioxide in the light conditions of these harmful substances oxidative decomposition can achieve the purpose of gas purification. by Jemma
