Test Methods

Tested by BET method,silica nanoparticle has large specific surface area.Through infrared spectroscopy method, SiO2 nanoparticle 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.

According to the Cary-5E spectrophotometer test, silica dioxide nanoparticle shows high reflectivity to long wave,visible light and ultraviolet ray.

By using 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 SiO2 produce 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.
