♦ Description
Sodium fluorosilicate is the byproduct in the production of calcium phosphate or
the production of fluoride salt in aluminum factory.
It generally appears as a white crystalline powder with low solubility in water
(being 1% or less at room temperature), and the water solubility increases slightly
with increasing temperature.
The aqueous solution of sodium fluorosilicate is acidic (pH3). This is due to that
its hydrolysis product contains hydrofluoric acid.
When pH is lower than 3.5-3.55, the hydrolysis reaction is stabilized. When
the pH is equal to 4, the hydrolysis reaction rate is significant. When the pH value is
equal to 8-8.5, the sodium fluorosilicate can be completely hydrolyzed to exhibit as
silica gel and precipitated out.
Therefore, when sodium fluorosilicate is added to the water glass, in addition
to hardening effect of precipitation of silicon dioxide gel caused by the neutralization
of the sodium hydroxide in the solution of water glass, the sodium fluorosilicate
itself is also a source of silica gel.

We have won the trust and support of customers around the world. We are always committed to serving our customers with the best sodium fluoride teeth and thoughtful service. Inquire! No sluggish components are available during the production of Yixin , because nearly all production stages are strictly under control and inspection, including the inspection of diodes and capacitors.
In order to achieve a compact and miniature design, Yixin is carefully designed with the help of advanced integrated circuits technology which gathers and encapsulates major components on a board.
In order to ensure users' safety, Yixin is strictly tested and has been certified under many international standards including FCC, CCC, CE, and RoHS.
Yixin is developed by adopting the most advanced integrated circuits technology. The R&D team makes the transistor, resistor, capacitor, and other components gather together to achieve a compact design.
During the production of Yixin , pollution or waste components generated from the production process is carefully and professionally treated. For example, the failed capacitor will be collected and disposed to a certain place.
Its electric circuits react flexibly and actively to the transmitted signals, which directly helps reduce the signal distortion rate.
