Seeing Invisible Resin
When manufacturing chipboards, it is important to correctly distribute the resin on the wood shavings. Researchers are now developing a measuring technique that makes it possible to monitor the application of the resin during production.
Particleboards have multiple purposes: they can serve as attic floors, practical wall constructions or packaging material. Designers and interior decorators value their natural look. The boards are increasingly made of wood residues. If flakes of a defined size are used, the resulting boards are known as OSBs "“ short for "oriented strand boards". The strands are mixed with resin and scattered in several layers to form a mat, which is then fed into a press on an endless conveyor. The boards are produced under immense pressure and at high temperatures.
Thanks to the new measuring technique, manufacturers of OSB will soon be able to monitor the distribution of the glue online and quickly detect any unevenness. This will help them to save costs and to further optimize their production processes. The researchers will be presenting the measuring principle at the Ligna trade fair in Hanover from May 18 to 22 (Hall 27, Stand J35).
