Activating Adhesives With Infrared
Activation of adhesives is one of many popular applications for infrared heat. Here are some examples.
- A coil of aluminum has adhesive applied in strips which is dried using shortwave infrared heaters from Heraeus Noblelight. The coil is cut into sheets which are overlayed with adhesive strips. The adhesive is cured in autoclave after which sheets are pulled to produce honeycomb structure. Previously the manufacturer used a hot air oven for drying the adhesive; the new infrared system runs faster and allows more homogeneous drying of the adhesive.
- A manufacturer of electrical white boards sought a method to heat glue. Heraeus Noblelight solved the challenge by providing carbon twin tube modules. Controlled by pyrometer, the system melts glue evenly so that brass wires can be pressed down into it.
- A laminating process required preheating of glue. The old method was a hot air oven that suffered from low speed and long heating time. A mediumwave modular system from Heraeus Noblelight provided high speed, reduced heating time, and a shorter production line.
These examples are by no means a complete list. Infrared heat is an effective and efficient means of applying process heat in many other applications.
