  • Jan 2009
Microwave energy was used to cure polymer coatings on instrument-grade woods provided by Taylor Guitars for this study. A processing method was developed which included spray coating the polymer onto raw wood panels and pulling the coated panels through a 2.45GHz multi-mode microwave cavity by means of a low-power motor. Characterization and testin...

Context 1
... experimentation with both single-mode and multi-mode microwave cavities, it was determined that a 2.45 GHz multi-mode cavity containing a low intensity electromagnetic field was less prone to burning the wood substrates, contained a broader field distribution allowing for processing of larger samples, and was easily controlled for this particular process. Figure 1 shows the complete microwave set-up used for wood processing. In order to accommodate large panels of wood (six inches by two feet) needed for vibrational testing, slots approximately seven inches long and one inch wide were cut in the sides of the microwave cavity. A pulley and conveyor system was developed and integrated into the microwave design. To contain leaks, a Faraday cage was constructed using wood and aluminum ...
