Thermal conductive filler nano alumina for LED encapsulation heat dissipation         It should put the heat conduction in the first place when heat dissipation of high power LED encapsulation is designed, because the heat conduct to the radiator from the LED packaging module first.Therefore,the bonding material, substrate is the key link of the LED heat dissipation technology.       Bonded materials mainly include thermal conductive glue, conductive silver slurry and alloy solder.Thermal conductive adhesive is to add some of the high thermal conductivity filler to the matrix, such as SiC, A1N, A12O3, SiO2, to improve the thermal conductivity.       the alpha nano alumina thermal conductive powder that HW NANO produces, high spheroidization rate,the small particle size, high purity, high thermal conductivity,used for thermal conductive filler such as epoxy resin, rubber, plastics, semiconductor packaging.       Alpha nano alumina, al2o3, particle size 200nm, 300nm, 500nm, 800nm, 1um... white solid powder, they are are all available with small quantity for researchers and bulk order for industry groups. 1kg per bags or 25kg per bucket or as needed for packing. application of nano alumina thermal conductive powder: 1. Thermal plastic. Adding the alumina powder can increase the coefficient of thermal conductivity of polypropylene (PP), and the coefficient of thermal conductivity of alumina/PP composite materials increase with the increase of dosage of thermal conductivity of alumina powder. 2. Thermal conductive silicone rubber.  Add the nano alumina powder can improve the coefficient of thermal conductivity of silicone rubber, and will not affect the transparency, appropriate adding quantity can make the coefficient of thermal conductivity of silicone rubber arrive 1.48-2 W/(m • K). 3. Heat conduction glue adhesion agent, such as agent of epoxy resin, epoxy resin, the thermal conductive coatings, etc., to add the alumina powder can make the coefficient of thermal conductivity arrive 0.6 W/(m • K) above. 4. Organic silicon thermal binder and mixture filler, radiator, radiator substrate with filler (MC), thermal oil, phase change, semiconductor packaging resin.

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.
