[ Chinese wardrobe net ] The materials commonly used in wardrobes are MDF (fiberboard), particle board (particle board), multi-layer solid wood board, large core board, etc. However, in terms of environmental protection and practical performance, several materials have their own advantages.
The fiberboard is made of plant fiber as the main raw material, and is processed by hot grinding, sizing, paving, hot pressing and the like. The fiberboard has a density, the density is below 450 kg/m3, which is called low-density fiberboard, the density is between 450 and 800 kg/m3, which is called medium density fiberboard, and the density is above 800 kg/m3. It is called hard fiberboard.
MDF is mainly used for the production of finished furniture, but also for laminate flooring, door panels, partition walls, etc. The utility model has the advantages that the surface is smooth and flat, the material is fine, and the shape and the milling type are convenient, the toughness is good, and the fracture is not easy to occur in the case of a small thickness. However, its moisture resistance is poor, the coefficient of expansion is large after absorbing water, the inside is powdery structure, the nail holding power is poor, the screw is easily loosened after screwing, the strength is not high, and the height of furniture cannot be too high. Most are 2100 mm. When the fiberboard is produced, due to its internal structural characteristics, the amount of glue used is large, and the environmental protection factor is low to a certain extent.
Particleboard is a piece of buds, small diameter wood, fast-growing wood, wood chips, etc., which are cut into certain specifications, dried, mixed with rubber, hardener, water repellent, etc., and pressed at a certain temperature and pressure. A wood-based panel is called a particle board because its section is similar to a honeycomb. Adding certain moisture-proof factors or moisture-proofing materials inside the particleboard has become a moisture-proof particleboard that people usually talk about. It is called a moisture-proof board. It has a certain moisture-proof effect because the particleboard itself has strong moisture resistance and the coefficient of expansion after absorption of water is higher. Small, widely used in cabinets, bathroom cabinets and other environments, but in reality, it has become a tool for many inferior particleboard to cover up the internal impurities.
Adding green coloring agent inside the particleboard has formed the green-based particleboard that is currently said in 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 mostly color substrates. The advantages are good sound absorption and sound insulation performance, heat insulation and sound absorption; the interior is granular with cross-displacement structure, the performance of each part is basically the same, the structure is relatively uniform, so the nail holding power is good, the lateral load-bearing capacity is good; the moisture resistance is strong It absorbs water and has a small expansion coefficient. It is widely used as raw materials for environmentally moist cabinets such as cabinets and bathroom cabinets.
The particle board has a small amount of glue in the production process and the environmental protection factor is relatively high. However, the inside of the particleboard is a granular structure, which is not easy to be milled; it is easy to cause a tooth in the cutting, so the processing equipment is required to be high.
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. Therefore, it is favored by consumers.
The wood board (commonly known as the large core board) is a plywood with a solid wood core, and its vertical direction (different from the core sheet) is inferior in bending strength, but the transverse bending strength is high. 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. The utility model has the advantages of good clamping force, high strength, strong quality, sound absorption, heat insulation, etc., the moisture content of the blockboard is not high, between 10% and 13%, the processing is simple, and the inside is solid wood strip, so The processing equipment is not demanding and is convenient for on-site construction. However, due to the large use of urethane glue in the production process of wood board, the formaldehyde emission is generally high, and the environmental protection standards are generally low, which is why most wood board tastes pungent.
At present, most of the wood board in the market is cut corners during production. When the solid wood strip is spliced, the gap is large, and there is a void inside the board. If the nail is nailed in the gap, there is basically no nail holding force. The solid wood strip inside the wood board is longitudinally spliced, so the vertical bending resistance is poor, and the long-term force will cause obvious lateral deformation of the board. The solid wood strip inside the wood board is different in material, the density is different, only after simple drying treatment, it is easy to warp and deform; the structure is distorted and deformed, which affects the appearance and use effect.
Special attention is paid to the fact that due to the rough surface of the wood board, when the woodworking site is processed, a large amount of glue or paint is usually used for the surface treatment. Therefore, the furniture made from the board is not environmentally friendly, which is why the decoration is very delicious. The main reason for the stimulation, such on-site furniture is the culprit of carcinogenicity and genetic mutations, and the damage to the human body is very large.
Electric lifting TV bracket,After the TV is hung on it, it can be controlled by the remote control.Let the TV automatic lifting in addition to bring visual enjoyment, the benefits are quite a lot. When you don't watch TV, you can completely hide it, reduce the occupation of space, and avoid dust falling into it. It's more convenient and practical for families who don't watch TV often.
