Multilayer board is a three-layer or multi-layer board like material made by rotary cutting wood segments into single boards or planing wood into thin pieces, and then bonding them with adhesive. It is usually made of odd numbered single boards, and the fiber directions of adjacent single boards are perpendicular to each other. Here is an introduction by the editor to the knowledge related to multi-layer boards. Let's learn more together!
Multi layer board usage:
Multilayer board is one of the commonly used materials in furniture processing enterprises and is a type of artificial board. A group of single boards is usually formed by bonding adjacent layers of wood grain perpendicular to each other, and multi-layer boards are usually symmetrically arranged on both sides of the central layer or board core. A slab made of glued veneers arranged vertically and horizontally in the direction of wood grain, pressed under heating or unheated conditions. The number of layers is generally odd, and a few may have even numbers. The differences in physical and mechanical properties in the vertical and horizontal directions are relatively small. Commonly used are multi-layer boards such as plywood and plywood. Multilayer boards can improve wood utilization and are a major way to save wood. It can also be used as functional materials for airplanes, ships, trains, automobiles, buildings, and packaging boxes.
Multilayer board, also known as sandwich board and plywood, has different names depending on the number of layers. According to the thickness of 3-9 centimeters, it can also be called a 3-9 millimeter board. Its quality mainly depends on the raw materials, and the price of each 1.2m and 4m board of Liuanxin is 10-20 yuan. And peach blossom and poplar wood are cheaper.
The main method used in home decoration is the veneer three plywood, which means that very thin solid wood veneer has already been applied to the three plywood in the factory. The decorative three panel panel is convenient to use and cheaper than buying a decorative panel for the construction team to stick.
The length and width specifications of multi-layer boards are the same as those of building templates, basically 1220 × 2440mm, while thickness specifications generally include: 3, 5, 9, 12, 15, 18mm, etc. The main tree species include camphor, willow, poplar, eucalyptus, etc.
The multi-layer board 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 coating, insulation, etc. The plywood has a high adhesive content, and edge sealing treatment should be done well during construction to reduce pollution during the day.
How to choose multi-layer boards?
① Multilayer boards have differences in front and back. When selecting, the plywood should have clear wood grain, a smooth and smooth front surface, without roughness, and should be flat without any clumping.
② The multi-layer board should not have any defects such as damage, bumps, hard wounds, scars, etc.
③ There is no delamination phenomenon on the multi-layer board.
④ Some multi-layer boards are made by pasting two single boards with different patterns together, so when choosing, it is important to pay attention to the tight seams of the plywood, without any unevenness.
⑤ When selecting multi-layer boards, attention should be paid to selecting non adhesive multi-layer boards. If the sound becomes crisp when tapping on various parts of the multi-layer board by hand, it indicates good quality. If the sound becomes dull, it indicates that the multi-layer board has scattered glue.
Multilayer board, also known as plywood, is one of the commonly used materials in furniture. Usually, its crown plywood surface and inner layer are symmetrically arranged on both sides of the center layer or core. Commonly used ones include plywood, plywood, etc. Plywood can improve wood utilization and is a major way to save wood. So, to learn more about multi-layer boards, you can only choose higher quality multi-layer boards during decoration!
