The combined core birch plywood has high strength and good bending resistance. In some structural parts that need to bear weight, the use of thin core plates will be more strong. But the stability is poor, which is due to the consistency of the core material. This makes the deformation of the fine core board likely to increase. Therefore, the fine core board is not suitable for single-sided parts, such as cabinet doors.
Combined core birch plywood is a board made by turning logs into large du veneers in the direction of bai annual rings, and after drying and gluing, the blanks are laminated and glued according to the principle that the wood grain directions of adjacent veneers are perpendicular to each other. .
Compared with natural wood, composite core birch plywood has the advantages of high wood utilization, good dimensional stability, small deformation, large specifications, rich surface decoration, good mechanical processing performance, etc. It is widely used in furniture, wooden doors and windows, wooden crafts, The production of packaging boxes; interior decoration materials such as wall skirts, suspended ceilings, decorative lines; and interior decoration of vehicles and ships are important materials for interior decoration and furniture production.
Generally, in the production of furniture, thinner products are mostly used for product backboards, drawer bottoms, sofa frames, sofa curved molding parts, and are widely used.
