Application Field

Rubber materials: carbon black, silica, calcium carbonate, zinc oxide, titanium dioxide, silica gel, silicon oxide and other chemical raw materials


Such materials are mainly tested its specific surface area; the size of surface area directly affects the mechanical properties of the rubber, such as hydrophobic silica. The tensile strength and breaking elongation of the silicone rubber increases since the surface area of hydrophobic silica is increasing.(Comparative found that the reinforcing effect of the hydrophobic silica is better than the hydrophilic silica, which is due to the hydrophobic silica are more uniformly dispersed in the rubber matrix, and the hydrophobic silica reinforced silicone rubber cross-linking density is greater).

 
Catalyst: petrochemical, chemical, pharmaceutical, food, agriculture, fine chemicals and other fields.


The specific surface area is an important parameter to characterize the performance of the catalyst. Generally speaking, the greater specific surface area of the catalyst, the more bits contact of the reactants, the mass transfer is also more smoothly, so the activity will be a large number. Containing the active center, the catalyst activity is higher. The performance of the catalyst is close to the specific surface area. Certain performance requires a certain range of surface area. (Such as Co / CZ catalyst requires a certain range of specific surface, the larger surface area, the better the catalyst and carbon smoke exposure).



Battery material: lithium cobaltite, manganese lithium, lithium iron phosphate, graphite, ternary materials, diaphragm, electrode materials, etc.


The specific surface area and porosity of battery materials is very important. The effect of specific surface area of the slurry preparation and the coating of pole pieces is large; it also has a impact in the first time columbic efficiency and cycling performance of the battery; the size of the porosity has the effect to the high magnification charge and discharge, and ultimately affect the cycle life of the battery (too large specific surface area of graphite, results in the first capacity loss too much, reduces the service life, and the binder will add more, resulting in increased internal resistance).

 

 
Magnetic materials: iron oxide, ferrite magnetic powder material
 


Fe3O4 magnetic powder for example, by modifications the surface area of the magnetic particles, we can obtain a magnetic material having large specific surface area and strong adsorption affinity for the oil droplets, thereby, improving effect for degreasing. It has great relationship between the size of the specific surface area of the ferrite magnetic powder and the strength of the magnetic material.

 


Adsorbent: activated alumina, molecular sieves, activated carbon, etc.


The specific surface area, pore volume, pore size distribution is essential, and directly affect the sewage treatment, industrial separation technology, and also directly affect the gloss, texture, color, color saturation, brightness, solids and film-forming adhesion (the porosity control paints and coatings application performance, such as mobility, drying or solidification time and film thickness).





Nanomaterials: nano ceramic powder (alumina, zirconia, yttrium oxide, silicon nitride, silicon carbide, etc.), the nano metal powders (silver, iron powder, copper powder, tungsten powder, nickel powder), nano polymermaterial, carbon nanotubes, etc.


The specific surface area and porosity of the nano-ceramic powder impacts the processing of pottery embryos, sintering solidified, the strength, texture, appearance, and density. The specific surface area of the glaze and glass raw materials affect shrinkage, crack, surface uneven distribution.

 


 Other material: microfiber, porous fabric, composite materials, soil, mud, sediment, suspended solids, special paper.
