Plywood manufacturers tell you that plywood is a three-layer or multi-layer plate-like material made of wood segments cut into veneer or thin wood by wood planing, and then glued with adhesive, generally with odd layers of veneer, and the fiber direction of the adjacent layer veneer is glued straight to each other.
In order to improve the anisotropy characteristics of natural wood as much as possible, so that the characteristics of plywood are uniform and the shape is stable, generally plywood must comply with two basic principles in structure: One is symmetric, the second is that the adjacent layer of veneer fibers are straight to each other, the symmetry principle is to require the veneer at both ends of the symmetrical center plane of the plywood, regardless of the nature of the wood, veneer thickness, layer number, fiber direction, water content, etc., should be symmetrical with each other, in the same piece of plywood, you can use a single tree species and thickness of the veneer, you can also use different tree species and thickness of the veneer, However, any two layers of symmetrical veneer species and thickness at both ends of the symmetrical center plane should be the same, and the surface plywood backplane is not allowed to be the same species.
In order to make the structure of plywood fit the above two basic principles together, its number of layers should be odd, so plywood is generally made of three layers, five layers, seven layers and other odd layers, the name of each layer of plywood is: The surface board is called the table board, the inner board is called the core board, the front board is called the panel, the back board is called the back board, the core board, the fiber direction is parallel to the table board is called the long core board or the middle board, in the formation of the chamber table board slab, the panel and the back board must face outward.
Delicate items with the right way to adjust their role to the extreme, here is a more common example, when people buy cabinets or other furniture, the most intuitive is to look at the shape of the furniture, but they do not know the plywood part of the furniture is also very important, a good piece of plywood can greatly progress the overall feeling of furniture, So how to adjust plywood for plywood manufacturers to maximize it, if you want to make this problem clear, then gradually listen to plywood manufacturers for you to explain.

In fact, in order to progress the role and role of plywood, the most important thing is that we can choose a suitable furniture plywood, to select plywood time we have to from the placement environment, the use of address and engineering nature and other aspects to consider, when you select plywood in accordance with these points, you will find that the selection of plywood raw materials, types, The grade and decorative function are different, so as to ensure that you can choose the right plywood, and then make the plywood more excellent, and can also march our taste and grade.
Plywood manufacturers can provide you with different environments, different types of high-quality plywood, trust that there is always a suitable for you, come to buy it.
Plywood has also become a multi-layer board, plywood manufacturers plywood in the construction decoration profession is widely used, packaging plywood in the packaging and transportation industry are widely used, today's packaging plywood manufacturers to introduce the selection of building plywood needs to pay attention to the key.
According to the nature of the project, the use of parts, environmental conditions and other factors to choose different varieties, grades, materials, decoration and format of plywood, room decoration should be selected precious wood planing thin wood veneer of building plywood, internal decoration with building plywood, should conform to GB50222 "building interior decoration planning fire standards" rules.
The hidden part that may be damp and the occasion with high waterproof requirements should be considered to choose Ⅰ class building plywood or Ⅱ class building plywood, outdoor use should choose Ⅰ class building plywood, panel decoration should preserve the natural color and texture of the wood surface, if you do not need to consider the markings and color of the plywood, should also be reasonable selection of appropriate plywood according to the environment and cost.
