Analysis of white carbon black in various fields
White carbon black is a general term for fine powder or ultrafine particles of anhydrous and water-containing silica or silicates. Large (greater than 90%), the original particle size is generally 5 ~ 40nm, because the surface contains more hydroxyl groups, it is easy to absorb water and become aggregated fine particles.

Use of white carbon (food grade silica) for transparent colored and opaque toothpaste,
Can increase the abrasion resistance of toothpaste and can keep the drug toothpaste stable.
Such as children's special repair toothpaste ...

Use of white carbon (fumed silica) in plastic films,
Not only improve its transparency, strength and toughness, but also can significantly improve the compactness, smoothness and wear resistance of plastic products.
Such as plastic film for packaging ...

Use of white carbon (fumed silica and precipitated silica) in sealants, adhesives,
It can speed up the curing speed, improve the bonding effect, and also significantly increase the sealing and permeability of the product.
Such as building sealant, glass glue ...

Use of white carbon (fumed silica) in cosmetics,
Can increase viscosity, improve overall stability, uniform pigment distribution, improve temperature resistance, and prevent discoloration.
Such as girls' various lipsticks ...

Use of white carbon (fumed silica) in paper,
Can improve the paper's resistance to ink transmission and mechanical strength, increase whiteness and reduce production costs.
Assorted stationery ...

Using white carbon (precipitated silica) in rubber soles,
Can make all kinds of soles have a variety of colorful colors, not just the traditional black,
Such as the tendon soles in casual shoes ...

Use of white carbon (precipitation or fumed silica) in silicone rubber,
Can greatly improve the elongation, strength and high and low temperature resistance of rubber products.
Such as silicone rubber bottles, pacifiers for babies ...

Add white carbon (precipitation modified silica or fumed silica) to the paint,
Will increase paint rheology and increase paint brightness,
Like all kinds of paints and coatings ...

Using white carbon (precipitation feed grade silica) in feed additives,
Because of its high adsorption value and flow promotion characteristics, it is an excellent carrier for various feed additives.
Such as feed acidifier ...

Add white carbon (precipitation food grade silica) to various milk powder, instant coffee, powdery soup and powder flavor,
White carbon black (food-grade silica) absorbs the moisture of the surrounding air with countless internal pores, preventing food from being damp and agglomerated during storage, which can keep the value of various foods fresh for a long time without mildew.
Such as instant coffee, powder seasoning ...

The use of white carbon (fumed silica) in electronic packaging materials,
Adding white carbon (modified fumed silica) to its encapsulation material, fully dispersed in the silicone modified epoxy encapsulant matrix, can greatly shorten the curing time of the encapsulation material, and the curing temperature can be reduced At room temperature, the sealing performance of OELD devices is significantly improved, and the service life of OELD devices is increased.
Such as foldable OLED new flat display equipment ...

Use of white carbon (precipitation method high dispersion silica) in automotive tires,
It can simultaneously improve tire life (improve wear resistance) and safety (improve wet skid resistance), reduce fuel consumption (reducing rolling resistance), reduce tire rolling resistance by 3-4%, and reduce fuel consumption by 1-2%.

The rolling resistance based on the tread is about 50% of the tire, and reducing rolling resistance is an important way to save fuel.
According to the sales of nearly 300 million tires in China in 2016, such as the replacement of these tires from ordinary tires to green tires,
It can save 41.3 billion liters of fuel each year, save nearly 247.8 billion in fuel costs, and reduce 95.94 million tons of carbon dioxide emissions!

If all cars in the capital use green tires, then carbon dioxide emissions can be greatly reduced!
Air quality can also be improved a lot!

In addition,
White carbon black can also be used in more fields such as resin, ceramics, glass steel, pesticides, etc.
It can be said that in many industries, white carbon black can be seen!
