Plates, usually made of standard rectangular flat construction materials, are used as components for walls, ceilings or floors. Also refers to forged, rolled or cast metal plate. Divided into thin plates, medium plates, thick plates, special thick plates, usually made of standard rectangular flat construction materials. The plates used for decoration include solid wood panels, plywood, veneer, and fine wood. For those types of uses and advantages and disadvantages, as a decoration you will soon know, let's fully understand the classification of the plates used for decoration. Advantages and disadvantages. Wood board (commonly known as Daxin board) Wood board (commonly known as the big core board) is a plywood with a solid wood core, and its vertical (differentiated by the direction of the core sheet) has poor flexural compressive strength but high transverse bending resistance. Most of the current market is solid, rubberized, double-sided sanding, five-layer blockboard, is one of the most commonly used plates in the current decoration. advantage: A. Blockboard screws have good grip strength, high strength, and have the characteristics of quality, sound absorption, heat insulation, etc. Blockboard moisture content is not high, between 10% -13%, processing is simple, for furniture, doors and windows Sets, partitions, false walls, heating covers, curtain boxes, etc. are the most widely used. B. Because the interior is a solid wood strip, the requirements for processing equipment are not high enough to facilitate on-site construction. Disadvantages: A. Due to the large amount of urea-formaldehyde glue used in wood board production, formaldehyde emission is generally higher, and environmental standards are generally low. This is why most wood boards taste pungent. B. At present, most of wood board production on the market is cutting corners during production. There is a large gap during the splicing of solid wood strips. Hollow holes are generally present in the interior of the board. If nails are punched at the crevices, there is basically no nail holding power. C. The solid wood strips inside the wood board are longitudinally spliced, so the vertical bending strength is poor, and the long-term stress will cause significant lateral deformation of the board. D. The wood strips inside the wood board are different in material and density, and only after a simple drying process, they are easy to warp; the structure is distorted and deformed, affecting the appearance and the use effect. E. Because the surface of the wood board is rough, when the woodwork is processed on the spot, a lot of glue or paint is usually used to treat the surface. Therefore, the furniture made from this plate is not environmentally friendly. This is why the taste is very exciting when decorating. The reason is that such on-site furniture is the culprit for carcinogenesis and genetic mutations, and it is very harmful to the human body. Particle board Particleboard is the process of cutting all kinds of shoots, trails, fast-growing wood, sawdust and other materials into pieces of certain specifications. After drying, it is mixed with rubber, hardener, waterproof agent, etc., and pressed at a certain temperature and pressure. A type of wood-based panel, which has a honeycomb-like profile, is called a particle board. Adding certain materials such as “moisture-proof factor†or “moisture-proof agent†to the interior of the particle board has become the moisture-proof particle board normally referred to by people. It is also referred to as moisture-proof plate for short. It has a certain moisture-proof effect because the particle board itself has strong moisture resistance and absorbs moisture. The post-expansion coefficient is small, and it is commonly used in cabinets, bathroom cabinets and other environments, but in reality, it has become a tool for many inferior particle boards to mask the internal impurities. The addition of green stains to the interior of the particle board creates what is currently referred to as green-based chipboard in the market. Many manufacturers use it to mislead green boards. There is no scientific basis. Domestic and foreign top brands of particleboard in fact more than the base material. advantage: A, good sound absorption and sound insulation; particle board insulation, sound absorption B. The inside is a granular structure with cross-staggered structure. The performance of each direction is basically the same and the structure is relatively uniform. Therefore, the nail holding force is good, and the horizontal bearing force is good. C. Strong moisture resistance, less coefficient of expansion after moisture absorption, and is commonly used in cabinets, bathroom cabinets and other environment-friendly cabinet products. D, particle board surface smooth, realistic texture, uniform bulk density, small thickness error, pollution resistance, anti-aging, beautiful, can paint and a variety of veneer; E, Particleboard in the production process, using a smaller amount of plastic, environmental protection coefficient is relatively high. Disadvantages: A. The interior is a granular structure and it is not easy to mill; B. It is easy to cause turbulence when cutting boards, so the requirements for processing equipment are high; Fiberboard (also known as density board) Fiberboard is plant fiber as the main raw material, after hot grinding, sizing, paving, hot pressing and other processes. Fiberboard has the density of density, the density is less than 450kg/m3 is called low density board fiberboard, the density is between 450-800kg/m3 is called medium density fiberboard (referred to as MDF), the density is 800kg/ More than cubic meters is called hard fiber board (HDF). MDF is mainly used for the production of finished furniture, but also for the strengthening of wood floors, door panels, partition walls and so on. advantage: A. The surface of fiberboard is smooth and smooth, and the material is fine. It can be easily shaped and milled. B, the toughness of the fiberboard is better, and it is not easy to break in the case of small thickness (such as 6MM, 3MM) Disadvantages: A. The moisture resistance of fiberboard is poor, and the coefficient of expansion after absorbing water is larger B. The inside of the fiberboard is a powder structure, which has poor nail holding power. Loosening of the screw is likely to occur. C. Since the strength of the fiberboard is not high, the height of the furniture can not be too high, most of which is 2100mm. D. When the fiberboard is produced, due to its internal structural characteristics, the amount of glue used is large, and the environmental protection coefficient is low to some extent. Solid wood finger board Fingerboard, also known as integrated board, glulam, and finger joint material, is a piece of solid wood small pieces that have been processed and processed like a “fingerâ€. Because of the zigzag interface between boards, similar to two fingers Cross docking, so called finger board. Since the raw wood strips are cross-linked, such a combined structure has a certain binding force, and since there is no need to stick the surface plate up and down, the glue used is extremely small. advantage: Since there are fewer junctions in the solid wood panels and less glue is used, the environmental protection coefficient is relatively high. With easy processing, cutting, drilling, sawing and forming. Disadvantages: Solid wood fingerboard is easily deformed and cracked. The quality of solid wood fingerboards is guaranteed but the cost is high. Wood particle board The so-called solid wood particle board, in fact, is a kind of particle board produced by the process of particle board, which is also considered to be a particle board of homogeneous particle board. The scientific name of the homogeneous particleboard is directional structure particleboard. It is a kind of material with small diameter, thinning material, wood core, board skin, branch material, etc. Processed and grown by special equipment 40mm, 70mm, width 5mm, 20mm, thickness 0.3mm, 0.7 The flaky pieces of mm, after drying, sizing, and special equipment, the core plywood pieces are arranged in a criss-cross pattern, and then the man-made board after the hot press forming. Homogeneous particle board will be flaking through the advanced single-channel drying machine after drying, the expansion coefficient is small, moisture resistance is very good, the implementation of its flaking plane is layered layered pavement, so its internal internal uniform texture than ordinary particleboard And powdered MDF holding nail force, bending resistance, stability must be strong. As a kind of high-grade environmental protection substrate, the oriented structure particleboard is widely used by European and American national furniture manufacturers, and the domestic high-end panel furniture market has also begun to use this kind of plate in a large area. Multi-layer solid wood board The multi-layer solid wood board is made of multi-layer plywood arranged in a criss-cross pattern, and the surface is made of high-quality solid wood veneer or technical wood as a fabric, and is manufactured through several processes such as cold pressing, hot pressing, sanding, and health care. Because the multi-layer solid wood panel has the characteristics of non-deformation and good performance in adjusting the indoor temperature and humidity, the surface layer wood veneer material has natural and real wood texture and feel, so the selectivity is stronger. Therefore, it is greatly favored by consumers. Multi-layer solid wood panels have good structural stability, are not easily deformed, and are rigid. Due to the vertical and horizontal gluing, high temperature and high pressure, the deformation of the solid wood plate is solved in terms of internal stress. In the production process, the use of self-made high-quality environmental protection rubber, so that the product's formaldehyde release limit to meet the national standards, green environmental protection. Melamine face The melamine finish is printed on the surface of the decorative paper, and is then impregnated with melamine adhesive to produce a melamine-coated paper, which is then hot-pressed on the sheet substrate. Because of its high surface flatness requirements, it is usually used for surface decoration of particleboard and medium density fiberboard. After the melamine crimson pressure veneer, this kind of plate is usually called melamine cyanide plate, which has a strong realistic surface texture, wear resistance, scratch resistance, and good water resistance. It is suitable for production and is mainly used for plate furniture. manufacture. The thickness of the decorative paper of the melamine cyanide board is divided into the weight (gram weight). There are the points of imported paper and domestic paper. The surface printing ink is divided into imported ink and domestic ink, and the effect is also very different. According to different dipping processes, it is divided into all three ammonia rubber and semi-three ammonia rubber, and the wear resistance coefficient of semi-tri-ammonia is not as good as that of all three ammonia. According to the different pressure of the steel plate when the decorative paper is hot pressed, it is divided into different effects such as smooth surface, hemp surface, embossing, cloth pattern, corrugated fiber and rain silk surface. Solid wood veneer board veneer: The wood veneer is attached to the MDF, particle board, multi-layer solid wood and other boards through a high-temperature hot press, and becomes a solid wood veneer. Since the veneer has the points of import and domestic, the valuable wood and the ordinary The wood can be divided into a larger range, so depending on the type and thickness of the solid wood skin, the level of the solid wood veneer is determined. The surface of solid wood veneer must be painted. Because veneer and paint are different, the same kind of veneer can make different effects. Therefore, veneer veneers have higher requirements for veneers and paints. Because of its true, natural and high-grade feel, the solid wood veneer board is the main decorative method adopted at home and abroad for high-grade furniture, but its relative materials and manufacturing costs are relatively high.
