What is plywood?
Plywood is a kind of three-layer or multi-layer plate-like material, which is made of wood segments cut into veneers by rotation or thin boards by wood squares, and then glued with adhesive. Usually, odd veneers are used, and the fiber directions of adjacent veneers are glued vertically to each other.
What are the advantages and disadvantages of plywood?
Advantages: light weight, clear lines, insulation, high strength and difficult deformation; Convenient construction, not suitable for warping, and good tensile strength of transverse stripes. Disadvantages: generally high cost; Plywood is not as smooth as medium-density fiberboard, and it is not as firm as medium-density fiberboard, with plywood as the base and decorative panels such as fireproof boards and aluminum-plastic boards stuck on the surface.
Plywood specification
When it comes to plywood specifications, it is necessary to talk about the length, width and thickness of the board. The length and width of the board will be slightly different due to different manufacturers, but generally it will be 1220×2440mm, 1220× 1830mm, 9 15× 1830mm. The thickness is determined by the number of layers of the adhesive sheet. In addition to the surface plate, the more layers of the inner plate, the thicker the thickness. Plywood can be roughly divided into three categories: 3, 5, 9, 12, 15, 18mm and so on. When processing different furniture, plates with different thicknesses will be used. Of course, their market prices are also different.
Special classification of plywood
Plywood partition plywood is divided into hardwood plywood and coniferous plywood, which is a kind of man-made board with the largest consumption and the widest use. It mainly plays the role of covering and partition in architectural decoration engineering. Broad-leaved plywood is made of broad-leaved wood (such as basswood, birch, ash, oak, colored wood, poplar, etc.). ) by rotating veneer and gluing; Conifer plywood is made by gluing pine veneer.
Above, we introduced some information about plywood for you. This paper mainly introduces the advantages and disadvantages and classification of plywood. You can see that we have divided these contents into four parts to explain them for you. First of all, we introduced what plywood is, and you can simply understand it. Then we introduced the advantages and disadvantages of plywood. Finally, we introduced the specifications and specific classification of plywood. Seeing this, I believe you will no longer be unfamiliar with plywood.
