Silicon Oxide Nanoparticles Features:
Nano-silica particles according to their structure are divided into two types: P-type (Porous particles) and S-type (Spherical particles). P-type nano-silica surface contains a number of nano-porous with the pore rate of 0.611ml /g; therefore, P-type has much larger SSA comparing to S-type (See US3436). US3440 is P-type and its SSA is ~640m2/g. Further more, P-type ultraviolet reflectivity is >85% , S-type >75%.
Silicon Oxide Nanoparticles Test Methods:
1. Transmission electron microscopy (TEM) method, nano-silica particle has small size, narrow particle size distribution.
2. BET method, nano-silica particle has large specific surface area.
3. Infrared spectroscopy method, nano-silica particle exists a large number of hydroxyl groups and unsaturated residual bonds on its surface, and forms the deviation from the steady state of the silicon oxide structure.
4. Cary-5E spectrophotometer testing method, nano-silica particles--high reflectivity to long wave and visible light about UV.
5. Omnisorp100CX surface area and porosity analyzer, P-type nano-silica surface contains a number of nano-porous with the pore rate of 0.611ml /g.
Silicon Oxide Nanoparticles Applications:
Paint, plastic, color rubber, magnetic materials, in addition, nano-silica can be widely used in ceramics (sugar) porcelain, gypsum, batteries, paints, adhesives, cosmetics, glass, steel, fiber, glass, and many other fields of environmental protection products the upgrading.
Recommended Dosage:
There is a wide range of product application in different fields with a large different amount of dosage, from 0.5 to 5.5%. The end user shall determine the quantity to be added through testing and make the best dosage choice for the best use.
