Let's take a look at the editors of the top ten brands of China's environmental protection sheet, Shenzhou Home, the advantages and disadvantages of wood board, particle board, fiberboard, solid wood finger joint board and multi-layer solid wood board and solid wood particle board. The common surface finish of the board is expected to be of some help when choosing furniture.

Wood board
The wood board (commonly known as the large core board) is a plywood with a solid wood core, and its vertical direction (different from the core sheet) is inferior in bending strength, but the transverse bending strength is high. Most of the market is now solid, glued, double-sided sanding, five-layer blockboard, which is one of the most commonly used plates in decoration.
advantage:
A. Blockboard has good clamping force and high strength. It has the characteristics of firmness, sound absorption and heat insulation. The moisture content of blockboard is not high, between 10% and 13%. It is easy to process and is used for furniture. The most extensive.
B. Because the interior is solid wood strip, the requirements for processing equipment are not high, which is convenient for on-site construction.Disadvantages:
A. Because of the large amount of urethane glue used in the production process of wood board, the formaldehyde emission is generally high, and the environmental protection standards are generally low, which is why most wood board tastes pungent.
B. At present, most of the wood board in the market is cut corners during production. When the solid wood strip is spliced, the gap is large, and there is a void inside the board. If the nail is nailed in the gap, there is basically no nail holding force.
C. The solid wood strip inside the wood board is longitudinally spliced, so the vertical bending resistance is poor, and the long-term force will cause obvious lateral deformation of the board.
D, the solid wood strip inside the wood board is different in material, the density is different, only after simple drying treatment, it is easy to warp and deform; the structure is distorted and deformed, which affects the appearance and use effect. E. Because the surface of the wood board is rough, when the woodworking site is processed, a lot of glue or paint is usually used in the surface treatment. Therefore, the furniture made from the board is not environmentally friendly, which is why the taste is very exciting during the decoration. The reason is that such on-site furniture is the culprit of carcinogenicity and genetic mutations, and it is very harmful to the human body.

Particle board
Particleboard is a piece of buds, small diameter wood, fast-growing wood, wood chips, etc., which are cut into certain specifications, dried, mixed with rubber, hardener, water repellent, etc., and pressed at a certain temperature and pressure. A wood-based panel is called a particle board because its section is similar to a honeycomb.
advantage:
A, has good sound absorption and sound insulation properties, particle board insulation, sound absorption and other characteristics.
B. The inside is a granular shape with a cross-displacement structure, the performance in each direction is basically the same, and the structure is relatively uniform, so the nail holding force is good and the lateral load-bearing force is good.
C. It has strong moisture-proof performance and has a small expansion coefficient after absorbing water. It is widely used as raw materials for environmentally-friendly cabinet products such as cabinets and bathroom cabinets.
D, the surface of the particle board is flat, the texture is realistic, the weight is uniform, the thickness error is small, the pollution resistance, the aging resistance, the appearance are beautiful, and the paint and various veneers can be carried out.
E. In the production process, the amount of glue used in particleboard is small, and the environmental protection coefficient is relatively high.
Disadvantages:A. The inside is granular and it is not easy to be milled.
B. It is easy to cause violent teeth when cutting boards, so the requirements for processing equipment are high.
Fiberboard
Fiberboard (also known as MDF) is made of plant fiber as the main raw material, and is processed by hot grinding, sizing, paving, and hot pressing. The fiberboard has a density, the density is below 450 kg/m3, which is called low-density fiberboard, the density is between 450-800 kg/m3, which is called medium-density fiberboard, and the density is above 800 kg/m3. It is called hard fiberboard. MDF is mainly used for the production of finished furniture, but also for laminate flooring, door panels, partition walls, etc.
advantage:
A. The surface of the fiberboard is smooth and flat, and the material is fine, which is convenient for modeling and milling.
B. The toughness of the fiberboard is good, and it is not easy to break in the case of small thickness (such as 6MM, 3MM).
Disadvantages:A. The fiberboard has poor moisture resistance and has a large expansion coefficient after absorbing water.
B. The inside of the fiberboard is a powdery structure, and the nail holding force is poor. It is easy to loosen after the screw is tightened.
C, because the strength of the fiberboard is not high, the height of the furniture can not be too high, the vast majority is 2100mm.
D. When the fiberboard is produced, due to its internal structural characteristics, the amount of glue used is large, and the environmental protection coefficient is low to a certain extent.

Solid wood finger joint
Finger joint board, also known as integrated board, laminated material, finger joint material, that is, a piece of wood that has been processed by deep processing like a "finger head". Because the wooden board uses a jagged interface, which is similar to the cross-docking of two fingers, it is called the finger joint. Since the raw wood strips are cross-joined, such a combined structure has a certain bonding force, and since the surface plate is not required to be adhered up and down, the glue used is extremely small.
advantage:
Since the joints of the solid wood panels are less, the amount of glue used is also less, so the environmental protection factor is relatively high. Easy to process, can be cut, drilled, sawed and shaped.
Disadvantages:
Solid wood finger joints are easily deformed and cracked. Good solid wood finger joints are guaranteed to be of high quality.

Solid wood particle board
The so-called solid wood particle board is actually a sheet produced by the particleboard process, and it is also considered to be a homogenized particle board.
The scientific name of homogeneous particleboard is called oriented structure particle board. It is a kind of small diameter material, thinned wood, wood core, board skin, twig and other materials. It is processed by special equipment to grow 40mm, 70mm, width 5mm, 20mm, thickness 0.3mm, 0.7. Mm of shavings. After drying, sizing and special equipment, the surface layer slab is vertically and horizontally staggered and oriented, and then a wood-based panel is formed by hot pressing. The homogenized particleboard is dried by an advanced single-channel dryer. The expansion coefficient is small and the moisture resistance is very good. The razor is oriented layered, so its internal internal texture is uniform, stronger than the ordinary particleboard and powdered MDF, the bending strength and stability.
Multi-layer solid wood board
The multi-layer solid wood board is made of multi-layer plywood which is arranged in a crisscross pattern, and the surface is made of high-quality solid wood veneer or technical wood as a fabric, and is produced by several processes such as cold pressing, hot pressing, sanding and health.
Due to the non-deformable characteristics of the multi-layer solid wood board and the good performance of adjusting the indoor temperature and humidity, the surface layer solid wood skin material has the texture and feel of natural and real wood, so the selectivity is stronger. Therefore, it is highly favored by consumers.
The multi-layer solid wood board has good structural stability, is not easy to be deformed, and is firm in quality. Due to the vertical and horizontal gluing, high temperature and high pressure, the deformation defects of the solid wood board are solved from the internal stress. In the production process, the self-made high-quality environmental protection glue is used to make the formaldehyde emission limit of the product meet the national standard requirements and be environmentally friendly.
