Applications: 

Carbon Black / White Carbon Black

Tire and rubber manufacturers find that the specific surface area of carbon black has great influences on the service life, friction and rubber performance. The carbon black or white carbon black with proper specific surface area can be selected according to the tire or rubber purposes.

 Nanometer Materials

Surface area and porosity of nanometer materials are decisive for their hydrogen storage, oxygen storage and special substance adsorption, such as the typical CNT (carbon nano tube).

 

Electric Field

 

The inner filling materials of capacitor require high specific surface, so as to produce capacitor with smaller volume but larger capacity. Likewise, in the design of ordinary batteries, it is also necessary to consider the material's specific surface area, so as to gain smaller volume and larger storage power.

New Energy Battery

 

New energy battery is the hot field for research currently. It controls the proper stored energy density by controlling the material's specific surface.

 

 Paints and Coatings

 

Filler surface area of paints and coatings affects the smoothness, texture, color, color saturation, brightness, solid content and film's adhesion property. The porosity can control the application program's performance, such as liquidity, curing time and coating thickness, etc.

 

Catalyst

 

 

Catalyst's active specific surface area and pore structure have great influence on the conversion ratio. Choose the aperture size to filter or transit some substance selectively, so as to create a selective catalyst, and in turn, produce the desired products.

 

 

Automobile Exhaust  

Purification of resultants of the automobile exhaust requires special catalyst material. The exhaust purification using transition metal is of important practical significance and economic value. The specific surface and porosity decide the efficiency, service life and economical efficiency of the exhaust conversion device.

 

 

Combustion Control

 

 

In the research and development of rocket propellant and explosive, it is necessary to control the combustion rate by controlling the material's specific surface. If the speed is too high, it may be more dangerous; while if the speed is too low, it may cause failure and inaccuracy.

 

 

Active Carbon

 

 

Besides serving as an extremely great carrier material, the active carbon is also an ideal filtering material. The filtering effects can be controlled by controlling the active carbon's specific surface and porosity. It has important application in the gas and liquid purification fields.

 

 

 

Pharmaceuticals 

 

The tablet dissolution rate and medical effect action time can be controlled by rationally distributing the effective constituents of the medicines on the filler with certain specific surface area and porosity.
