? In the multilayer board production In the process of processing and R & D, the sizing methods for veneer are mainly dry sizing and wet sizing. Moreover, these two different processes have different effects in characteristics and results.

? In dry sizing, the special impregnated paper made from kraft pulp is impregnated with phenolic resin, and then dried and sheared. The method is that the glue is evenly distributed and the bonding quality is high. It is suitable for the situation of small veneer thickness and difficult sizing. However, the cost is high and its application is limited. The liquid adhesive is coated on the surface of veneer by wet sizing method. Make the glue liquid form a film with uniform thickness, and the veneer is coated with a layer of glue on the surface through the glue curtain. The adhesive with high viscosity or foam glue is coated on the surface of veneer through the small hole of extruder. The most commonly used manufacturing method for multilayer board manufacturers.

 Multilayer board

? No matter what kind of veneer sizing method is used, multilayer board production Manufacturers should make a comprehensive study from the production cost, economic benefits and the impact of product quality to determine the final beneficial method.
