[ Chinese wardrobe net ] Wood board (commonly known as large core board) is a plywood with solid wood core. Its vertical direction (different from the core sheet) is inferior in bending strength, but the transverse bending strength is higher. 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.
Second, multi-layer solid wood panels
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. The formaldehyde emission limit of multi-layer solid wood board meets the national standard requirements and is environmentally friendly.
Third, the large 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 the homogenized particle board is the oriented structure particle board. It is a kind of slab that is processed by special equipment with small diameter material, thinned wood, wood core, board skin and twigs. It will be dried, sizing and special equipment. A wood-based panel after being subjected to hot-press molding after the core layer of the core layer is oriented in a criss-cross direction. The large-Asian homogenized particleboard is dried by an advanced single-channel dryer. The expansion coefficient is small and the moisture resistance is very good.
Fourth, MDF (also known as MDF)
MDF is made of plant fiber as the main raw material, and is processed by hot grinding, sizing, paving, hot pressing and other processes. 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, called medium density fiberboard (MDF), and the density is 800 kg/ More than cubic meters is called hard fiberboard (HDF). MDF is mainly used for the production of finished furniture, but also for laminate flooring, door panels, partition walls, etc.
Five, solid wood finger joint board
Finger joint board, also known as integrated board, laminated material, finger joint material, that is, a piece of solid wood piece that has been processed by deep processing like a "finger head", because the wooden board uses a jagged interface, similar to two fingers Cross docking, so called the fingerboard. 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.
