The role of infrared halogen heating lamps for glass bonding:
Heating and softening glue
During the glass bonding process, glue is usually used.infrared quartz heating elements emit infrared radiation that can be absorbed by the glue. After the glue molecules absorb infrared energy, the vibration and rotation of the molecules intensify, causing the temperature of the glue to rise.
Speed up the curing process
For some glues that need to be cured,replacement infrared halogen lamp can significantly accelerate the curing speed. Many glass glues solidify through chemical reactions, a process that usually requires certain temperature conditions.
Improve adhesion
Infrared heating can increase the temperature of the glass surface, thereby improving the wettability of the glass surface. At an appropriate temperature, the surface energy of the glass surface will change and its affinity for glue will increase.
Just like in cold weather, water easily forms droplets on the glass surface, and when the glass surface is heated, the water spreads more easily on the glass. When glue is applied to a heated glass surface, the glue is able to spread and penetrate better, making the contact between the glue and the glass closer. This helps improve bond strength and prevents the glass from debonding during use.
Remove moisture and air bubbles
During the glass bonding process, there may be some moisture or bubbles in the glue or on the glass surface. The heating action of an infrared halogen heating lamp can evaporate this moisture.
The moisture turns into water vapor and is discharged from the glue or glass surface, avoiding problems such as degradation of glue performance or corrosion at the bonded joint due to moisture residue. At the same time, the flow of glue during the heating process also helps to discharge air bubbles. If bubbles remain in the bonding area, they will reduce the bonding strength, but heating to expel the bubbles can enhance the bonding effect between the glasses.
