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.

silicon nanopowders with high purity as the lithium battery anode material .

Sperconductivity Copper Oxide Nano Powder with high quality and competiive price .

High Quality Spherical Metal Zinc Nanopowders Appication Hongwu International Group Ltd with HW NANO brand offer a highly diverse range of Zinc nanopowder grades with average grain sizes from approx. 40nm to 150nm. We provide technical support in the selection of the powders suitable for specific applications and for questions regarding process optimization.     Zinc nanopowders holds the features of regular spherical shape, less surface oxidation, spherical surface smooth, clean, melting deformation and adhesion into grape-like, very few particles of the platform, good dispersion, uniform particle size, which is conducive to the production of high-quality anti-corrosion coatings. Besides it is with large surface area, small loose proportion, high efficiency coating cover, and good chemical reduction effect.     Zinc nanopowders possesses the nanometer effect that is with excellent chemical activity and good uv resistance, antistatic properties, antibacterial antibacterial, remove odor resistant enzymes and a series of unique properties. To use the antibacterial ability of silver, copper, and zinc metal materials etc., through the methods of physical adsorption of ion exchange, to fix the silver, copper, zinc and other metal ions ( or its ion) on the surface of porous material such as calcium fluoride, silica gel made from antibacterial agent, then join the corresponding products, it can obtain materials with antibacterial ability.     Because Zinc nanopowders has the characteristics of nano material, its application field has been widened to the plastics industry, sunscreen cosmetics products, special ceramic products, adhesives, paint coating, special function as well as chemical fiber textile health processing and producing uv, deodorant, antiseptic bacteriostasis of special fiber products, etc.     In whole, as a new kind of material, metal Zinc nanopowders have many unique properties in chemical, optical, electrical and biomedical fields. It appears the wide application prospect in magnetic materials, electronic materials, optical materials and high-strength, high-density materials, catalysts, sensor. by Jemma
