Effect of moisture content of multi - layer parquet veneer

For example, in the same substrate slab, some veneers have a moisture content of 7% and some veneers have a water content of 14%. After the veneers have been coated and hot-pressed, The moisture content of the finished substrate sheet varies unevenly, although the substrate sheet is flat just out of the press. When the moisture content is rebalanced, the resulting sheet will warp and distort.

If the slab in some areas of high moisture content, but also produce stratification. Therefore, we should try to control the moisture content of veneer within the scope of process requirements. Veneer coating should be uniform, you can extend the aging time appropriately, so that before slab layer and the various points of the moisture content of the balance.
