1. Blockboard (commonly known as large core board)

Wood board (commonly known as large core board) is plywood with solid wood core. Its vertical bending and compressive strength is poor (according to the direction of the core board), but its transverse bending and compressive strength is high. At present, the plates on the market are mostly solid, glued, double-sided frosted and five-layered, which is one of the most commonly used plates in decoration.

Personal opinion: In fact, the environmental protection coefficient of wood boards with better quality can also be guaranteed, but the cost is also high, and with many processes such as post-painting, an environmentally friendly product will become more or less environmentally unfriendly. Usually, furniture rooms made of blockboards need more ventilation, and it is best to leave them vacant for a few months before moving in.

2. Core plate

Particleboard is a kind of artificial board, which is made by cutting all kinds of branches and buds, small diameter wood, fast-growing wood and sawdust into pieces of certain specifications, drying them, mixing them with rubber, hardener and waterproof agent, and pressing them at a certain temperature and pressure. Because its cross section resembles a honeycomb, it is called particleboard.

Adding certain raw materials such as "moisture-proof factor" or "moisture-proof agent" into particleboard becomes what people usually call moisture-proof particleboard. Because particleboard itself has certain moisture-proof performance and small expansion coefficient after water absorption, it has certain moisture-proof effect, so it is widely used in cabinets, bathroom cabinets and other environments, but in fact it has become a tool for many inferior particleboards to cover up more impurities inside. Adding green dye into particleboard forms what is called green particleboard on the market at present. Many manufacturers use it to mislead it to become a green environmental protection board, but there is no scientific basis. Most of the top brands of particleboard at home and abroad are natural substrates.

3. Fiberboard

When some merchants say that they are making cabinets with high-density boards, they might as well weigh the board weight per unit area according to the above density standards to see if the density is high-density boards, or sell medium-density boards as high-density boards. This may affect the interests of some businesses, but from the perspective of doing business in good faith, we will not be afraid of customers to verify.

4. Solid wood finger joint board

Finger joint board, also known as integrated board, integrated board and finger joint board, is a kind of board made of small pieces of solid wood after deep processing, like a "finger". Because the interface between plates is serrated, similar to the cross joint of two fingers, it is called finger joint plate. Because the logs are cross-glued, the gluing structure itself has a certain adhesive force, and because there is no need to stick panels up and down, the amount of glue used is extremely small.

Before, we used camphor wood as the back plate of the cabinet and even sold it as a selling point. However, some cracks and deformation did occur in the later use, so we later canceled the use of camphor wood as the back plate of the cabinet. Here, I would like to remind customers who want to make finger-jointed cabinet furniture that they must carefully choose the plates, and the cracking and deformation that may occur in the later period should be negotiated with the producers. No matter whether it is a businessman or an individual, they all speak first and have less trouble later.

5. Particle board

The so-called solid wood particleboard is actually the board produced by the particleboard process, which belongs to homogeneous particleboard.

Homogeneous particleboard, scientifically called oriented structure particleboard, is a product made of small diameter wood, thinning wood, wood core, veneer and branch wood. And processed by special equipment to grow 40 mm, 70 mm, 5 mm, 20 mm wide, 0.3 mm thick and 0.7 mm thick. After drying, sizing and special equipment, the surface layer and core layer are laid crosswise and directionally, and then hot-pressed and formed. After being dried by the advanced single-channel dryer, the large-scale sub-homogeneous particleboard has small expansion coefficient and excellent moisture-proof performance. Its particleboard is paved layer by layer, so its internal texture is uniform, and it is superior to ordinary particleboard and powder density board in nail holding force, bending resistance and stability.

6. Multi-layer solid wood board

Multi-layer solid wood board is made of criss-crossing multi-layer plywood as the base material and high-quality solid wood veneer or technical wood as the fabric on the surface, through cold pressing, hot pressing, sanding, curing and other processes. Because the multilayer solid wood board has the characteristics of difficult deformation and good indoor temperature and humidity adjustment performance, the surface solid wood veneer material has the texture and feel of natural solid wood and has stronger selectivity. Therefore, it is favored by consumers.

The multi-layer solid wood board structure has good stability and is not easy to deform. Due to vertical and horizontal gluing and high temperature and pressure, the deformation defect of solid wood board is solved from the aspect of internal stress. Self-made high-quality environmental protection glue is used in the production process, so that the formaldehyde emission limit of the product meets the requirements of national standards and is green and environmentally friendly.
