(known as large core board) is a plywood with a solid wood core. and its vertical direction (different from the core sheet) is resistant to bending strength. But, the lateral bending resistance is higher. Most of the market is now solid, glued, double-sided sanding, five-layer blockboard, which is one of the most used sheet in decoration.
In fact, in the quality of blockboard, its environmental protection factor can also guaranteed. But, the cost is also high, and with the addition of many processes such as lacquering, it will become more friendly. Usually, in a furniture room made of wood board, it must ventilated. It is best to leave it for a few months.
2. Particle Board
Particleboard is a piece of buds, small-diameter wood, fast-growing wood, wood chips, etc.,
which cut into certain specifications, dried, mixed with rubber, hardener, water repellent, etc.,
which pressed at a certain temperature and pressure. A wood-based panel called a particle board because its section is like a honeycomb.
Adding certain materials such as “waterproof factor”
or “waterproof agent” inside the particleboard has become a waterproof particle board that people usually talk about. It called a waterproof board. It has a certain waterproof effect. because the particle board itself has certain moisture resistance and absorbs water. After the expansion coefficient is small, it used in cabinets, bathroom cabinets and other environments. but in reality, it has become a tool for many inferior particleboard to cover more internal impurities.
Adding green dyeing agent inside the particleboard has formed the green-based particleboard. that is currently said by the market. Many manufacturers use it to mislead into a green board. There is no scientific basis. The particleboards of top brands at home and abroad are actually colored substrates.
When some merchants say that they are high-density sheet making cabinets. it is possible to weigh the weight of the sheet per unit area according to the density standard. Check if it is a high density board. It is still sold as a high-density board with MDF boards, which may affect the interests of some merchants. But, from the perspective of honesty and business, it is not afraid of customers to verify that they are high-density boards.
4. Solid Wood Finger Joint Board
Finger joint board, also known as integrated board, laminated board, finger joint material. that is, a piece of solid wood piece that has been deep processed and processed like a "finger head". Because the wooden board uses a jagged interface, which is like the cross-docking of two fingers, it called the finger joint. Since the raw wood strips are cross-coupled, such a combined structure has a certain bonding force. and since the surface sheet is not required to adhered up and down, the glue used is small.
5. Particle Board
The solid wood particle board is actually a board produced by the particle board process, which is a kind of homogenized particle board. The scientific name of homogeneous particleboard called oriented structure particle board. It made of small diameter material, thinned wood, wood core, board skin, branch and other materials. It 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 and staggered and oriented. and then a wood-based panel formed by hot pressing. The large-Asian homogenized particleboard dried by an advanced single-channel dryer. The expansion coefficient is small and the moisture resistance is very good. The razor designed to oriented layered. so its internal internal texture is uniform, and it has stronger nail holding power, bending resistance. and stability than ordinary particle board and powdered MDF.
6. Melamine Faced Plywood Board
The melamine faced plywood board made of multi-layer plywood which arranged in a crisscross patternm. and the surface made of high-quality wood veneer or technical wood. It made by several processes such as cold pressing, hot pressing, sanding and curing. Due to the non-deformable characteristics of the melamine faced plywood 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.
Thus, it favored by consumers. The melamine faced plywood board has good structural stability and is not deformed. Due to the vertical and horizontal gluing, high temperature and high pressure, the deformation defects of the solid wood board solved from the internal stress. In the production process. the self-made high-quality environmental protection glue used to make the formaldehyde emission limit of the product meet the national standard requirements. and be green and friendly.
