Abstract In this work a new
microwave-heating procedure is presented as a viable alternative for both the
conventional and ultraviolet (UV) curing systems used in the natural stone
industry. Both thermal simulations and experimental tests demonstrate that
microwave energy highly reduces curing and storing times while maintaining
the product’s final quality. Several polymer mixtures have been obtained from
commercial products and fillers for maximum microwave absorption and their
complex permittivity has been properly measured. A continuous industrial
microwave oven has been built specifically for this purpose and tested on Crema-Sierra Puerta marble
samples and commercial epoxy and polyester resins. |
