1.What is solid wood multilayer board?
Solid plywood board is generally made of three or more layers of thin wood by gluing and hot-pressing, and its core material is made of solid wood segments by rotary cutting or wood square planing; Solid wood multilayer board, also known as plywood, is a commonly used board in furniture manufacturing. Solid wood board is different from particleboard, which is made of wood fiber chips, while solid wood board is made of complete logs, so it has better texture. The thickness of multilayer board usually includes six types: 3cm, 5cm, 9cm, 12cm, 15cm and 18cm, and its various properties will vary with the thickness.
2.Advantages of solid wood multilayer board?
- It is strong and not easy to deform. Because it is a multi-layer structure, the internal arrangement structure is staggered, which ensures that the multilayer board has good stability and strong tensile and bending resistance.
- Good waterproof and moisture-proof performance. Generally, the veneer or paint on the exterior of the solid wood multilayer board can play a waterproof effect, equivalent to a protective film.
- High surface flatness. The surface of the solid wood multilayer board is covered with a layer of high-quality solid wood veneer, which is processed by high temperature, high pressure, sanding and other processes. Therefore, the surface is flat, and the handle is exquisite, which can reflect the high-level feeling.
3.Disadvantages of solid wood multilayer board?
- Large amount of glue. The amount of glue used for the multilayer board is proportional to the number of layers. If the manufacturer does not use environmentally friendly glue, the more the number of layers, the more likely the content of harmful substances such as formaldehyde will exceed the standard.
- Lack of beauty. Due to technological reasons, the multi-layer board cannot be carved with patterns. The overall appearance is very simple, so the decoration and aesthetics are insufficient.
- It is difficult to repair after damage. The internal structure of the multilayer board is tight. Although the thicker the board is, the greater the strength is, the deformation will occur once it exceeds a certain limit. It is difficult to repair it back to its original shape.
4.Notice of for the purchase of solid wood multilayer board?
The performance of multilayer boards is good in all aspects, so many manufacturers are producing them, which makes the quality of products on the market uneven. Pay attention to the following points when purchasing:
- Look at the surface layer: solid wood multilayer board is composed of core material and surface layer. The surface course greatly affects the overall aesthetics and service life. The surface of high-quality plates will not have defects such as dead knots, wormholes, cracks, skin clips, etc.
- Look at the core material: the more layers of the core material of the multilayer board, the closer it is pressed, the higher its strength, the more stable its structure, and the better its waterproof.
- Look at glue: glue directly affects the environmental protection effect and service life of the plate. The more layers of the plate, the greater the amount of glue used; We should pay attention to whether there is pungent smell when purchasing. If there is any indication that the plate is not environmentally friendly, we can also ask the manufacturer to issue a quality inspection report.
