The solid wood furniture in the store will be clearly marked with the materials used, such as water chestnut, crabapple wood, black walnut... Consumers can intuitively understand the materials used in the furniture just by their names. But buying board furniture is not so easy. There are various names for artificial boards, such as density board, plywood, Osoon board, particle board, etc., which make consumers confused.

Here, the editor tells everyone that no matter what new boards are launched in the market, they are all slightly modified based on the traditional "three boards". Therefore, regardless of the name of the board, it cannot be separated from the traditional category of "three boards". Let's break through the fog and see the essence, and understand what these "three boards" really are!

■ Plywood

Also known as: plywood, plywood, multi-layer board, plywood, particleboard, large core board, sandwich board, woodworking board

Plywood refers to the process of cutting wood segments into thin wooden boards called veneers, stacking odd numbered layers of veneers vertically according to the fiber direction of adjacent layers, and then bonding them together. The commonly used plywood and plywood refer to the number of layers in plywood. Henan Hongda Wood Industry is a manufacturer specializing in the production of plywood. The company's series of products such as Guangqiang brand multi-layer solid wood panels and poplar plywood are highly favored by customers.

Fine woodworking board, also known as large core board, woodworking board, sandwich board, belongs to a type of plywood, which refers to a special type of plywood made by covering one or two layers of veneer on both sides of the core board and then pressing it with glue. The core board is made of small wooden blocks pieced together. Unlike ordinary plywood, which has equal thickness in each layer, particleboard has a thick middle layer and thin layers on both sides, which is why it is called "sandwich board".

Advantages and disadvantages: The veneers are glued vertically to each other, with low internal stress and high stability, making them relatively less prone to deformation. Less glue consumption and better environmental friendliness compared to other artificial boards. Good nail grip, can be assembled twice.

■ Fiberboard

Fiberboard, also known as density board, refers to a type of artificial board made by mechanically separating and chemically treating wood or plants into wood fibers, adding adhesives and waterproofing agents, and then forming them under high temperature and high pressure. According to different densities, it can be divided into low-density board, medium density board, and high-density board. Medium density board is used in home building materials. Aosong board is actually medium density board.

Advantages and disadvantages: The surface of the density board has good decorative properties, and various coatings and paints can be evenly applied to the density board. It is the substrate for making paint effects and is also easy to process into the desired shape. The disadvantage is that the moisture resistance of the density board is poor, and it is prone to expansion and deformation when exposed to water. In addition, the fibers of the density board are very fragmented, resulting in poor nail grip and making it difficult to perform secondary assembly.

■ Particle board

Also known as: Particle board

Particle board, also known as particleboard, is a type of artificial board made by cutting various branches, small diameter wood, fast-growing wood, sawdust, etc. into fragments of certain specifications, drying them, mixing them with glue, hardener, waterproofing agent, etc., and pressing them under certain temperature and pressure. The particles are unevenly arranged. Although particle board is also called particleboard, it is not the same type of board as solid wood particle board. Solid wood particle board is only processed similarly to particleboard, but its quality is much higher than that of particleboard.

Advantages and disadvantages: Particle board has good insulation and sound absorption properties, as well as good lateral load-bearing capacity. Low cost, mostly used for office furniture. Adding waterproofing agents during production makes it less likely to deform. Poor nail holding force makes it difficult to perform secondary assembly.

Expert answer:

Is E0 grade artificial board more environmentally friendly than solid wood?

There is currently a voice in the market that many salespeople emphasize when introducing panel furniture to consumers that they use E0 grade panels that are currently environmentally friendly, even more environmentally friendly than many solid wood furniture. Is this true?

As is well known, solid wood furniture is environmentally friendly because it does not use glue. The boards used in panel furniture require a large amount of adhesive during production, and formaldehyde mainly comes from these adhesives. The so-called E0 level labeling does not mean no formaldehyde emission, but refers to formaldehyde emission ≤ 0.5mg/L, so it can only be said that this type of board is very close to the environmental friendliness of solid wood. Although formaldehyde content is extremely low, attention should also be paid to the quantity. When used in large quantities in a certain space, the combined amount of formaldehyde emissions will still exceed environmental standards.

In addition, E0 grade boards themselves contain relatively less adhesive and moisture-proof agent, which reduces their moisture resistance and toughness, making them less suitable for humid environments such as kitchens and bathrooms.
