Hi guys,

Fuser Film Sleeve is widly used in laser printer.  And the most informant feature of it is good fixing effect. Our product Silicon Carbide nanoparticle has anti-wear, thermal conductivity, anti-scratch features.  So when you put Silicon Carbide nanoparticle into PI, which is one of the raw material of Fuser Film Sleeve, you will find that the anti-wear, thermal conductivity, anti-laceration features of Fuser Film Sleeve will be improved many times.  Now it is very popular in some of our local customers.   If you are interested, we are willing to provide our good-quality products, good-quality technology,  good-quality service for you.

we would like to introduce for you our nano SILICON particle which could be used in the negative material of the lithium battery.  Compared with other negative materials such as graphite, mesocarbon microbeads,  petroleum coke  which have been in commercialized use, the alloy Si-Li, Sn-Li, Al-Li has much more higher lithium storage than graphite which has theoretical value 372 mAh/g. The value of alloy Sn-Li is 990 mAh/g,  Al-Li 990 mAh/g,  Si-Li 4200 mAh/g.  Now the alloy as negative material of the secondary lithium battery becomes popular research point.  I believe that your company must make research in this area and I am sure that the particle size of silicon you use is about 1um.

Our company is the leading manufacturer of nano carbide and nano nitride particles. We have our own proprietary technology of production-----plasma arc vapor synthesis method.   We use H2 to react SiCl4,  then we get nano SILICON which is single- phase.  Our product SILICON has four features of high purity, small particle, uniform diameter distribution, high surface activity, large specific surface area.  At present in the world, we are the only one which realizes the industrial production of SILICON below 100 nm.

The specific parameter of our product SILICON is as followings:

The decrease of the size of silicon particle (below 100nm) could effectively decrease the expansion resulting from silicon absorbing the lithium ion, reduce the loss of silicon, and improve the recycle capacity.  With the vapor method, the nano silicon particle has higher surface activity, easily to match with many kinds of material to form composite materials. As that it is more flexible in applications.

The way now in China to apply silicon particle in the negative material of lithium battery is :  coat the surface of silicon with carbon material, then form Si-C composite material.   As the matrix, the carbon not only could be embedded with Lithium, but also the transmission channel of electron and atom.  Si-C composite material,  the carbon matrix is unformly embedded in nano SILICON., and the crystal does not change before and after forming the composite material. Nano Si-C composite material not only has high recycle and stability character as the same with the carbon material, which could prevent the silicon material from activity loss of lithium embedded due to volume expansion and migration, but also has the feature of high specific capacity as the same with Si material.

Energy-saving mechanism of nano TiN:

Nano TiN have transition of electron as absorbing infrared, transit from high energy level to low energy level, then release much energy.  When TiN is heated fully mixed with metal materials, because nano TiN releases energy interior and improve the temperature inside of the furnace, largly improve the smelt rate of metal, and improve the efficiency of metal smelting. Then save the energy for a wide range.   Proof by emperiment: It reduces to 4 hours from 6 hours when smelting 750 KGS steel in intermediate frequency inductive stove.  This technology is mainly used to improve smelting rate and low down the loss of steel making.

Grain refinement mechanism of nano TiN:

Nano TiN comes into lattice to make alloy nucleation small to refine alloy grain., then improve the performance of alloy. The thinner of grain, the more of crystal grain boundary unit volume.  Because atomic array of crystal grain boundary is more disorder than atomic array of internal grain, the dislocation is high. As that, the crystal grain boundary snarls with slip dislocation normally caused by grain, then it is not easy to keep slipping across the boundary, the deformation resistance is increased, and it performances the improvement of intensity(part of mechanism). 

Nano alloy breaks the law of usual production of alloy, which is the conculsion  of hardness improvement necessiarly with reduction of toughness. For small sized grain, the high surface activity of nano TiN could make grain combine rapidly, then make the size of grian larger and low the driving force as the combination of grains.   And finally it forms the whiske structure inside the alloy, then improve the hardness and toughness of alloy.

From the above, nano TiN applied in smelting steel, could not only save energy, but also improve every mechanical property of steel.  This technology are widly used in metal smelting, ceramic sintering, powder metallurgy. And it could help such industies save much more energy, and improve the quality.
