99.9% Nano Silicon Oxide (dioxide) Powder Silica Sio2 Nanopowder / Nanoparticles

Product Description

Product Description

Brief introduction

Product name: Silicon oxide SiO2
Purity: 99%-99.999%
Particle size: 20-30nm, 50nm, 100nm, 45um, 100un, 200um, etc
Type: hydrophilic, hydrophobic
Color: white powder
Bulk Density: <0.10 g/cm3
True Density: 2.4 g/cm3
Ultraviolet Reflectivity:>75%.

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 US3440). US3436 is S-type and its SSA is ~170-200m2/g. Further more, P-type ultraviolet reflectivity is >85% , S-type: >75%.

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.
 

Application:

1 Rubber modified, sealant ceramic toughening modification, adhesives, functional fiber additive, plastic modification, paint aging additives;
2 Ceramics, nano ceramic, composite ceramic substrate;
3 Polymer: can increase the thermal stability and anti-aging polymer;
4 Flame retardant materials and coatings, high grinding medium, cosmetic products;
5 In cluster butyl benzene and chlorinated polyethylene adding a small amount of nano SiO2produce color rubber tenacity,
elongation, strength, flexural performance and ultraviolet resistance and thermal aging performance and achieve or exceed epdm;
6 In traditional coating adding a small amount of nano silicon oxides, good solve the suspension stability, thixotropy and poor, poor finish.
