The technology is about supplementing 1D press drying, which has already been in large-scale industrial use at Junckers for 60 years, with patented, laboratory-tested factors that deliver the results.
The technology has also been confirmed to meet the patentability criteria (novelty, inventive step and industrial applicability) in the official examinations of two separate patent applications. The first patent is already largely verified in practice by the press drying carried out at Junckers.
The operations of the latter patent are performed on wood that is dry and equivalent to planed wood. During them, the wood's own binders and the external chemicals remain in an almost molten state until the start of the cooling phase has been passed. This allows the profile and volume of the product blank, and of its parts, to be changed during the production process.
The solidification of the substances in the cooling phase sets, i.e. locks, the product in its final state. Thus the gluing and surface treatment of green and also of drier timber take place only once the wood is dry to final-product moisture and its treated surfaces have been compressed by a forming process equivalent to planing.
It stands to reason that glues and coatings adhere more firmly to wood surfaces through hot pressing than with current techniques, i.e. spraying, rolling and brushing.
The adhesion of both substances and the durability of the surface wood are greater in products suited to the topography-following surfaces that the Solidiwood process makes possible.
The powerful hot pressing of the Solidiwood process, and the compression of the surfaces to be glued into an at least somewhat topographic form, produce a bond that is even stronger than with current technology. It does not, however, need to be as strong as current bonds. In Solidiwood products the glue lines lie, at least as a rule, on or near the centre line of the cross-section.
