Silicon dioxide cas 14808-60-7 Description
Silica is a raw material for manufacturing glass, quartz glass,
water glass, optical fiber, important parts of the electronics
industry, optical instruments, handicrafts and refractory
materials, and an important material for scientific research. In
addition, silica can also be used as a lubricant and an excellent
flow promoter, mainly as a lubricant, anti-sticking agent, and
glidant. It is especially suitable for the granulation of oils and
medicinal extracts, and the prepared granules have good fluidity
and compressibility. It can also be used as a glidant in direct
compression. As a disintegrant, it can greatly improve the fluidity
of the particles, increase the bulk density, increase the hardness
of the prepared tablets, shorten the disintegration time limit, and
increase the dissolution rate of the drug. It can be used as an
internal desiccant in the manufacture of granules to enhance the
stability of the drug. It can also be used as filter aid,
clarifying agent, defoaming agent, suspending agent and thickening
agent for liquid preparations.

Silicon dioxide cas 14808-60-7 Usage
Silica use
1.
To be used as a desiccant, dehydrating agent, moisture-proof agent
and air humidity regulator. It is also used for gas drying. It is
also used as a catalyst and catalyst body, a reinforcing agent for
silicone rubber, and a sizing agent used in the textile industry.
2.
Mainly used as liquid adsorbent, desiccant and perfume carrier, can
also be used as catalyst carrier
3.
As a hygroscopic agent, its color changes from blue to red with the
increase of moisture absorption to show the change in the humidity
of the space medium of the sealed package
4.
Used as a catalyst carrier for important petrochemical products
such as phthalic anhydrid, melamine, butadiene rubber, and
acrylonitril. It is also widely used in refining petrochemical
products, removing aromatics, and selectively adsorbing and
separating certain organic gases and liquids. It can also be used
as an ion exchanger to remove multivalent harmful elements in
water. And used for the dry storage of materials, equipment and
other items and the dewatering and refining of high-purity gases.
5.
It is used in precision casting instead of ethyl silicat to reduce
production costs, improve the operating environment and improve
product quality. Used as an adhesive for refractory materials and
other materials. It is a coating material to prevent oxidation of
certain products. As a matching material for paint (internal and
external wall water-based paint) to improve bonding, fastness,
abrasion resistance, and pollution resistance. As a synthetic fiber
treatment agent to improve the friction coefficient of the fiber.
As a warp sizing agent for wool spinning industry, it can improve
spinnability, feel, reduce flying and end breakage, and increase
output. Used in paper industry to improve paper smoothness and
paper strength. It is also used as an abrasive and catalyst for the
finishing of electronic materials, and a coagulant for sulfuric
acid in batteries.
