Particleboard is a kind of artificial board made by cutting various 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.
Finger joint board is also called integrated board, integrated board and finger joint board, that is, it is a board made of small pieces of solid wood after deep processing like "fingers". 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.
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.
Multi-layer solid wood board is based on criss-crossing multi-layer plywood, and its surface is made of high-quality solid wood veneer or technical wood through cold pressing, hot pressing, sanding and curing. 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. Generally speaking, there are many on the market at present.
Finger joints should be varnished, because solid wood will crack over time.
The eco-board has decorative surfaces on both sides, and several kinds of wood in the middle layer are not painted. It is better to import Malacca core and other two kinds of boards, and the prices are basically the same.
