DESCRIPTION:

Precipitation silica commonly known as white carbon black, also called hydrated silicate, lightweight silica, Formula is mSiO2 · nH2O.

 

Product features:

The appearance is white powder of highly decentralized and amorphous characteristics. It is sold as commodities after processed into granular. Its specific gravity is 2.319 ~ 2.653, the melting point is of 1750 ℃. Insoluble in water and acid, absorbing moisture from the air, it will become fine particle and gathered together. It is soluble in KeXingNa and hydrofluoric acid.

 

For other chemicals it has stable characteristics. It does not decompose, does not burn with high temperature resistance. Has the very high electrical insulation, porous, inside the large surface area, has good water absorbability, non-toxic.

 

 

  

Applications:

Precipitated silica (pesticides class): this product as dry powder of pesticide carrier has good compatibility for other Pesticide components, has a very small volume absorption pesticide component, and thus be able to assure a long drug release

In the agricultural chemical products, such as pesticides, efficient spraying fertilizer etc, with white carbon black as carrier or thinner, can maintain lasting effect, because it has the high adsorption dynamics, easy to suspension, good affinity and chemical stability. Even in the rain, washing and hot conditions, can still long-term remain unchanged.

It is widely used in almost all of the crops, because it is non-toxic and just as a carrier of pesticide.
