Question:

Can the present nanometer silica dioxide replace the foreign silicon dioxide in China?

Can the present nanometer silica dioxide replace the foreign silicon dioxide in China?

Answer:

Can be replaced, only few domestic technology can not keep up with foreign countries, the cost of the sound field is relatively large.The main factors for the size of nano silica are specific surface area, type, main hydrophobic silica, hydrophilic silica two categories.
The main factors for the size of nano silica are specific surface area, type, main hydrophobic silica, hydrophilic silica two categories.Fumed silica is a by-product of polysilicon production, the production of silica nanoparticles (Degussa, Wacker chemical giant, Kabo PL) in China have set up factories, to achieve a localization.Domestic production enterprises also have production, compared with the chemical giants gap is mainly a variety of single, lack of stability! It's important to choose a good supplier. Domestic enterprises also need to continue their efforts, and can not allow foreign companies to use our resources to pollute our environment, but also to earn our profits.

Domestic silicon dioxide do generally lower, with foreign products there is a certain gap. Look at the specifications of nano silica mainly uses two different, you can refer to dewort chemical, nano silica practice they do the same, can be comparable to foreign products.
