Silica is widely exist in nature, is the main component of ceramics, glass, and other none-metallic products. Especially ultrafine silica, due to it's small particles size so large specific surface, strong surface attachment, high chemical purity, good dispersion performance. With it's excellent stability, ultrafine silica is become widely use in rubber, plastics, coatings and other filed. Today let us to take a look about the application of ultrafine silica in these major filed.
1.Silica Use in Plastic
The white carbon silica dioxide can be add in the plastic to improve the toughness of the material without weakening the rigidity of the material, and even improve the rigidity of the material.
The addition of Pyrogenic Silica to epoxy resin can significantly improve its brittleness and overcome the material rigidity caused by the toughening of elastomers.Defects with reduced sex and strength to achieve the purpose of enhancing toughening.
2.Silica Use in Rubber
- Application in vulcanized silica rubber
The most widely use in rubber is Fumed Silica, it's mainly plays a reinforcing role. Because of silica molecular chain is very submissive, the linkage molecular silica action is weak. So it's must to strength vulcanized silica.
- Application in Medical Rubber
Use fumed silica as rubber reinforcing agents, the physical function is well. It's widely use in medical filed, which relate to each medical department. Such as medical gloves are belong to medical rubber.
- Application in Daily Necessity
Ultrafine silica has good physical performance taht can be application in many kinds of household appliances.
3. Silica Use in Coatings
- Silica put use into UV coatings
UV coatings is an environmentally friendly and energy-saving coating developed in the 60s of the 20th century. Compare with traditional coating, UV coatings is economic, environmentally friendly.
- Silica put use into construct coatings
Ultrafine silica can reduce the color difference value cause by the UV and infrared light irradiation.
Color inkjet printing paper is often apply in the filed of life, especially many companies often use it for file printing. But, because it has micropore and flaw in the surface then need a coating to improve the paper's performance. Accordingly, add ultrafine silica into inkjet printing can largely improve the coating effect and high quality of paper, to provide excellent performance for paper.
- Silica put use into metal protective coatings
Ultrafine silica not only use widely in rubber, plastic, inkjet printing paper, but also in matal protective coatings. If ultrafine silica be add into matal coating that can enhance quality of coatings.
