1、Application in tires
Silica is used as a reinforcing agent, and the largest amount is in the rubber sector, where it accounts for 70% of the total. Silica significantly improves the physical properties of rubber, reduces rubber hysteresis, and lowers the rolling resistance of tires without loss of their resistance to wet skidding. In the rubber industry, carbon black is a very effective reinforcing agent, its biggest disadvantage is that it can not be used to prepare colored products. Ultrafine silica as reinforcing filler for the production of green tires, can be used in place of carbon black in the sidewall, can significantly increase the sidewall of the tear strength and resistance to crack growth performance, while no significant effect on the vulcanization time, resistance to ozone aging is dependent on the amount of antioxidants and silica. Adding silica to the tread rubber of tires can improve the tread's cut and tear resistance, and reduce the bouncing and falling blocks. The rolling resistance of silica-filled rubber can be reduced by 30% compared with ordinary carbon black-filled rubber.
2、Application in defoamer
Vapor phase silica generally have hydrophilic and hydrophobic two kinds of products, which hydrophobic products is the use of hydrophilic products after the surface chemical treatment, now the defoamer manufacturers generally use hydrophobic vapor phase silica, the use of its surface hydrophobic groups to attract the hydrophobic end of the surfactant in the foaming system, so that hydrophobic solid particles into a hydrophilic, thus reducing the concentration of surfactant in the foam, and thus improve the speed of defoaming. Promote the foam rupture and improve the defoaming speed.
3、Application in paint and coating industry
Silica can be used as rheological additives, anti-sinking agents, dispersants, matting agents in the production of coatings, thickening, anti-sinking, thixotropy, matting and so on. It can also improve the weather resistance and scratch resistance of coatings, improve the adhesion strength between the coating and the substrate as well as the hardness of the coating, improve the aging resistance of coatings, and improve the ultraviolet absorption and infrared light reflection properties.
4、Application in electronic packaging
Through the surface-active treatment of fumed silica fully dispersed in the silicone-modified epoxy resin encapsulation adhesive matrix, you can significantly reduce the encapsulation material curing time (for 2.0-2.5h), and the curing temperature can be lowered to room temperature, so that the sealing performance of the OLED device has been significantly improved to increase the service life of the OLED device.
The addition of fumed silica application so that the past need to be in a special environment to realize the process of electronic device encapsulation is reduced to room temperature conditions, significantly reducing production costs, and shorten the encapsulation material curing time, greatly improving the production efficiency and reduce production costs, the popularization and application of a new generation of OLED display technology has a promotional role.
