Why are plywood cheaper than solid wood?
Solid wood refers to pure solid wood, that is, all materials are not re processed natural materials, do not use any man-made board made of furniture. Solid wood furniture has pure solid wood furniture and imitation solid wood furniture. Pure solid wood furniture, that is to say, all the wood furniture is solid wood, including desktop, wardrobe door panels, side panels are made of pure solid wood, do not use any other forms of artificial board.
One of the commonly used materials for furniture is an artificial board. A set of veneers usually glued together in a direction perpendicular to the direction of the adjacent layers of wood. Usually the table plate and the inner plate are symmetrically arranged on both sides of the central layer or the core of the plate. A single slab made of glued sheets that are Criss crossed in the direction of wood grain. The number of layers is generally odd, and even a few are even. The physical and mechanical properties of the vertical and horizontal directions are less different. There are three commonly used plywood, plywood etc.. Plywood can improve wood utilization, and it is a main way to save wood. They can also be used in aircraft, ships, trains, automobiles, buildings and packing boxes.
Without changing the physical properties of wood after drying, after liposuction, a process that can be called wood paint. Plywood (Plywood: commonly known as: multilayer board) is one of the common furniture materials, is a man-made board. The plywood is logs into veneer or by wood sliced veneer, with adhesive glued into three or more layers of sheet material, usually with odd veneer, and the fiber direction of adjacent plates perpendicular to each other and gluing. Is the destruction of the physical properties of wood itself, which plays a leading role in the composition of glue, so it will not crack, but it can not be called wood, there are now a wood particle board, MDF, particleboard and other sheet rubber ingredients except outside is sawdust, sawdust, straw and other wood fiber containing something very cheap, so the production cost is very low in density so the market price is cheaper than wood.
