Application of Silicon Dioxide
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.
Characteristics of Silicon Dioxide:
1) White dispersed powder
2) Can be dissolved by NaOH and HF, but cannot be dissolved by other kinds of acid, water and solvents
3) It has a good performance
4) With resistance to higher temperature
5) Will not combust and has good isolation
