Nano gold colloids with good stability

Our client said Nano colloidal gold and gold nanoparticles of Hongwu are unrivaled – we found that your company the best that we could work with.”

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

The porous, high dispersion and high activity alpha aluminum oxide nanopowders apply to the nano ceramic material.

Nano titanium nitride powder is a good heat resistant materials.

This transparent antibacterial nano silver dispersion run the wonderful antibacterial effect, solution we use is deionized water.

Silver micron powder has spherical or flake morphology, 1-2um or 3-8um,widely used in conductive filler.

Graphene nanoplatelets has good thermal conductive,widely used in plastics.

Rutile Type Nano Titanium Oxide, shielding ultraviolet ability and excellent transparency, has excellent compatibility with other raw material.

Silicon oxide nano powders (SiO2,20NM,99.8%,Amorphous) Silicon oxide nano powders as the amorphous white powder, is a kind of non-toxic, tasteless, no pollution non-metallic materials. silicon oxide nano powders modification: 1. Alcohol, acid modification Experiments showed that alcohol and acid compounds will react with a large number of -OH of silicon oxide nano powders surface, so organic groups are grafted in the surface of nanoparticles, and the hydrophobic properties of the modified powders got improved, so as to improve the compatibility of the nano powders and organic matter 2. Surfactant modification 1) by physical adsorption surfactant is adsorbed on the surface of nanoparticles; 2) certain groups of surfactant react with -OH of the surface of the particles,which achieve the goal of the surface modification of the particles. 3. The silane coupling agent modification Experiments show that the coupling agent reduce the interaction between particles, and influence degree of different coupling agent on the modified samples is different. Stock# M600 and M602: hydrophilic SIO2, 10-20NM and 20-30NM,99.8% Stock# M603 and M606: hydrophobic SIO2,10-20NM and 20-30NM,99.8%                        1kg per bag for sample, 10kg per bag for the hydrophilic, 5kg per bag for the hydrophobic The main application of silicon oxide nano powders       HONGWU NANO silicon oxide nano powders, more than 8 years of market and technology development, has been widely used in electronic packaging materials, polymer composite materials, plastics, coating, rubber modified, paint, ceramics, adhesive, glass fiber reinforced plastic, drug carrier, cosmetics and sterilization field, which bring epoch-making significance for an upgraded version of a traditional product.

CHEMICAL Aluminum/ Al Particle for Polishing Paste with 1-3um in 99.5% purity apply for the firwork.

Nano cesium tungsten oxide powder can effectively block infrared and ultraviolet light.
