What is plywood and what are its characteristics?

What is plywood? It is one of the boards commonly used in home decoration and is a common type in daily life. So how much do you know about plywood? As a commonly used board for home decoration, it has its own characteristics that are difficult to replace. Next, I will talk about its characteristics.

1. What is plywood?

Tri-plywood is also called multi-layer board and plywood. The names are different depending on the number of layers. It is rotary cut from wood sections. Veneer or a three-layer plate-like material made of wood sliced ??into thin pieces and then glued together with adhesive. Usually an odd number of layers of veneer are used, and the fiber directions of adjacent layers of veneer are glued perpendicular to each other. Tri-plywood is a plate material with three layers bonded together.

Its quality mainly depends on the raw materials. Nowadays, veneer plywood is mainly used in home decoration, that is, very thin solid wood veneer has been pasted on the plywood in the factory. Veneer plywood is easy to use and cheap.

Plywood is one of the commonly used materials for furniture and is a kind of artificial board. A group of veneers are usually assembled and glued together perpendicular to each other in the direction of adjacent layers of wood grain. Usually the crown plywood surface panel and inner layer panels are symmetrically arranged on both sides of the central layer or core. The slab is made of glued veneers criss-crossed in the direction of the wood grain, and is pressed with or without heating. The number of layers is generally an odd number, but a few also have an even number. The differences in physical and mechanical properties between the vertical and horizontal directions are small. Commonly used ones include plywood, five-ply board, etc. Plywood can improve wood utilization and is an important way to save wood.

Characteristics of 2 and 3 plywood

The 3 plywood structure has good strength and stability. It has the advantages of light material, high strength, good elasticity and toughness, resistance to impact and vibration, easy processing and painting, insulation, etc. The plywood contains a large amount of glue, so edge sealing must be done during construction to reduce pollution.

Plywood not only has all the advantages of natural wood, such as light weight, high strength, beautiful texture, insulation, etc., but it can also make up for some of the natural defects of natural wood, such as knots, small format, deformation, and vertical and horizontal mechanics. The difference is huge.

Plywood production can make rational use of logs. Because it has no sawdust, this product is mainly used in various panels for furniture manufacturing, interior decoration, and residential construction.

1. Uniform internal structure, moderate density, good dimensional stability and small deformation.

2. The physical and mechanical properties such as static bending strength, internal bonding strength, elastic modulus, board surface and board edge screw holding force are all better than particleboard.

3. The surface is flat and smooth, which is convenient for secondary processing. It can be pasted with rotary cut veneer, sliced ??veneer, painted paper, impregnated paper, and can also be directly painted and printed for decoration.

4. Medium-density fiberboard has a larger format, and the board thickness can also vary from 2.5 to 35mm, and can be produced according to different uses.

5. The mechanical processing performance is good, and the processing performance of sawing, drilling, tenoning, milling and sanding is similar to that of wood, and some are even better than wood.

However, adhesives are used in the production process of plywood. We all know that the reason why many wooden furniture contains formaldehyde is due to the problem of these adhesives, so we must identify the genuine ones when purchasing. If it is fake, it is best to choose brand products produced by regular manufacturers.

After reading the above information, I believe everyone also knows more about the common plywood than just its name, right? Because of its characteristics, it has a wide range of uses and is used in many different ways. However, consumers still need to identify the authenticity and quality when purchasing.
