Description

Technical Field

[0001] This utility model relates to the field of plywood technology, specifically to a moisture-proof and pressure-resistant plywood. Background Technology

[0002] Plywood is a sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets, and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain directions of adjacent layers perpendicular to each other. Plywood is a commonly used material in furniture making and one of the three major types of engineered wood products. It is also used in aircraft, ships, trains, automobiles, construction, and packaging. A set of veneers is usually glued together with adjacent layers having their grain directions perpendicular to each other. The face veneer and inner veneer are usually symmetrically arranged on both sides of the core layer. The plywood blank, made by gluing veneers with the grain direction crossed, is pressed under heated or unheated conditions. The number of layers is generally odd, but an even number is also possible. The physical and mechanical properties in the longitudinal and transverse directions are relatively similar. Common types of plywood include three-ply and five-ply. Plywood improves timber utilization and is a major way to conserve timber.

[0003] Existing plywood has poor overall strength and is easily damaged by pressure deformation. Furthermore, it does not have moisture-proof properties and is prone to mold growth, thus failing to meet the needs of users. Utility Model Content
