Improperly cured adhesive is one of the worst thing that happen in Laminated Veneer Lumber (LVL) engineered wood product. When glue doesn’t stick properly, the result can include delamination, loss of structural integrity, and inutility. Industrial microwave improve the cured glue procedures by reducing footprint, time and manpower, and by increasing productivity and quality.

How Microwave Cured and Dry Adhesive

We must admit that when a water molecule to an electric field like the one produced in a microwave oven, the changing electric filed in the oven twists the molecule around by its charges2.45 billions times per second. Bounce a water molecule around a few billion times a second like this, and it gets hot and heats up everything around it. The same working principle is the molecules in the glues that bind layers of wood together, they bounce around just like water molecules in a microwave oven.

Microwave Cured Wood Glues

Because microwave process is so fast, it also reduces the danger of glue dry-out during the lay-up stage. Microwave produce a lower coefficient of variability(COV) in the final product. The drawback to microwave is higher capital costs, but the payback is faster than with conventional system.

MAX industrial conveyor microwave ensure a direct and rapid curing of glue, particular application to the thicker, longer products.
