In many fields such as construction, automobiles, and electronics, glass glue is widely used for bonding and sealing between glass and glass, and between glass and other materials. However, glass glue often produces bubbles during use, which not only affects the appearance of the glue, but also may reduce the bonding strength and sealing performance of the glue. Therefore, the application of defoamer for glass glue is particularly important.
The main working principles of defoamer for glass glue are as follows:
1. Reduce surface tension: Defoamer can reduce the surface tension of glue, thin the liquid film of bubbles, and cause bubbles to rupture.
2. Destroy the stability of bubbles: Defoamer can destroy the surface film structure of bubbles, causing bubbles to lose stability and then rupture.
3. Inhibit the generation of bubbles: Some defoamers can adsorb on the surface of glue before bubbles are formed, preventing air from entering the glue, thereby inhibiting the generation of bubbles.
With the continuous development of the glass glue industry and the improvement of glue performance requirements, defoamers for glass glue are also constantly innovating and developing. Research and develop defoamers with higher defoaming efficiency and stronger targeting to meet the needs of different glass glue systems and application scenarios.
In short, defoamers for glass glue play an important role in the production and use of glass glue. By rationally selecting and using defoamers, the bubble problem of glass glue can be effectively controlled, the performance and quality of glue can be improved, and the sustainable development of the glass glue industry can be promoted.
