Seek classification of wood, their names, characteristics, prices

1, according to the material can be divided into: solid wood, man-made boards two categories. At present, in addition to the floor and the door will use solid wood panels, generally we use the board are man-made processing out of artificial board. 2, according to the molding classification can be divided into: solid board, plywood, fiberboard, decorative panels, fire prevention board and so on. Second, the varieties of wood panels. 1, solid wood panels As the name suggests, solid wood panels are made of intact wood lumber. These panels are strong and durable, natural grain, is a good choice in the decoration. However, due to the high cost of such panels, and construction technology requirements, but not much use in the decoration. Solid wood panels are generally classified according to the material name, there is no unified standard specifications. 2, plywood plywood, also known as plywood, commonly known in the industry as fine core board. By three or more layers of one-millimeter-thick veneer or veneer glued and hot-pressed. Is currently the most commonly used materials for handmade furniture. Plywood is generally divided into 3% of the board, 5% of the board, 9% of the board, 12% of the board four specifications (1 cents is 1mm). 3, decorative panels decorative panels, commonly known as panels. Is a solid wood board precision planing into a thickness of 0.2mm or so thin veneer, plywood as a substrate, after the gluing process made of decorative panels with a single-sided decorative effect. It is a special way of plywood existence, the thickness of 3%. Decorative panels are currently different from the practice of mixing oil a high-level decoration materials. 4, Blockboard Blockboard, commonly known in the industry as large core board. Large core board is made of two pieces of veneer in the middle of the adhesive pressure splicing board and become. The price of large core board is cheaper than the fine core board, its vertical (to distinguish between the core material towards) poor bending strength, but the horizontal bending strength is higher. 5, particle board Particle board is made of wood chips as the main raw material, and then seeped with glue, additives by pressing the thin plate. According to the pressing method can be divided into extruded particle board, flat pressure particle board two categories. The main advantage of such boards is that the price is extremely cheap. The disadvantage is also very obvious: the strength is very poor. Generally not suitable for the production of larger or mechanical requirements of home furniture. 6, density board density board, also known as fiberboard. Wood fiber or other plant fibers as raw materials, applying urea-formaldehyde resin or other applicable adhesive made of man-made panels, according to its density, divided into high density board, medium density board, low density board. Density board due to soft impact resistance, but also easy to reprocess. In foreign countries, density board is a good material for making home furniture, but due to the national standards on the height of the board several times lower than the international standards, so the use of density board in our country's quality has to be improved. 7, fire prevention board Fire prevention board is the use of siliceous materials or calcium materials as the main raw material, with a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives mixed, made of decorative panels by the autoclave technology. Is now more and more use of a new type of material, its use is not only because of the factor of fire prevention. The construction of fire prevention board for pasting glue requirements are relatively high, the price of better quality fire prevention board than decorative panels are also expensive. Fire prevention board thickness is generally 0.8mm, 1mm and 1.2mm. 8, melamine board melamine board, full name is melamine impregnated film paper veneer man-made board. It is the paper with different colors or textures into the melamine resin adhesive soaked, and then dried to a certain degree of curing, it will be laid on the surface of particle board, medium density fiberboard or hard fiberboard, hot-pressed and made of decorative panels. Melamine board is a kind of wall decorative material. At present, some people use melamine board to fake laminate flooring for floor decoration, which is inappropriate. Three. Selection of the board first look at the environmental protection according to the implementation of January 1 this year, "indoor decoration materials and products in the formaldehyde emission limit of man-made boards," the requirements of the building materials used directly for indoor formaldehyde emissions must be less than or equal to 1.5 milligrams per liter, if the amount of formaldehyde emission is less than or equal to 5 milligrams per liter, it must be treated with a finish to be used for the indoor formaldehyde emission exceeds 5 milligrams per liter. That is, substandard. Bring home unqualified wood is like a new home to add a gas generator, buy building materials must first look at the environmental protection is not environmentally friendly. 1, joinery board "core board": moisture effect is good, can not be painted directly The middle of the joinery board is made of natural wood glued to the core, the two sides of the veneer glued on a very thin, as the name suggests core board, is one of the most important materials in the decoration. It can be used to make furniture and package wooden doors and door covers, heating covers, curtain boxes, etc. Its waterproof and moistureproof performance is better than particle board and MDF. In the selection to see its internal wood, should not be too broken, the gap between the wood in the 3mm or so of the joinery board is appropriate. Due to the surface of the exposed wood grain is not beautiful, rarely painted directly, usually to paste the veneer plywood. Furniture and other woodwork made with large core boards should be glued and painted after two processes, the cost is higher. Large core board according to the thickness is divided into 3, 5, 9, 15, 18% board, we can choose according to the pressure and strength, the thicker the higher the price. Many consumers choose the big core board, a look at the weight, two look at the price. In fact, the heavier the core board, the worse its quality. Because the greater the weight, the more this board shows the use of mixed wood. This is a large core board made of mixed wood, simply can not be nailed into the nails, so can not be used. In addition, the price is very low core board, its quality will certainly be very poor. Either the gap is large, or the use of substandard wood. So when you choose, it is best to choose about 100 yuan a big core board. The quality of the core board at this price is more stable. The market price of 50-55 yuan a big core board, simply can not be used. Selection of large core board is to look at the appearance: one side of the large core board must be a full sheet of wood, the other side only allows a seam. In addition, the surface of the board must be dry and clean. In addition, when you choose a large core board, you must saw a corner and check the quality of the inside. The small strips of wood spliced inside must have a gap of no more than 5 millimeters, and wood with bark, moth holes and dead knots must not be used. Good quality coreboards have sawtooth mortise and tenon joints between the small strips of wood. In use, the large core board can only follow the long side of the "smooth open", can not be sawed across the use. In addition, the core board can not be used as a panel, to stick a layer of plywood outside as a panel, otherwise there will be paint blistering and other problems. 2 integrated material, not easy to deform This is an emerging solid wood materials, using high-quality imported large diameter logs, deep processing and staggered like fingers spliced board. Due to different processes, the environmental performance of this board is superior, is allowed to contain formaldehyde core board 1/8, the price of about 200 yuan per sheet, slightly more expensive than high-grade core board. But on the other hand, this kind of American spruce and other solid wood produced by the plate can be directly on the color, paint, to save a process than the core board, the final calculation of the construction costs may be flat. 3, MDF than particle board nail grip poor particle board is natural wood crushed into particles, after pressing into the board, is currently the main material of the cabinet. MDF is molded with powdered wood chips by pressing, better flatness, but poor moisture resistance. In contrast, the density of the board's grip is poorer than particleboard, screws screwed if the loose, due to the density of the board's strength is not high, it is difficult to re-fix, so it is rarely used to do the cabinet. 4, veneer three plywood save trouble and cheap Multi-layer board, also known as three plywood and plywood, different layers called different. According to the thickness of 3-9 centimeters, can also be called 3-9 centimeter board. Its advantages and disadvantages mainly depends on the raw materials, willow core each 1.2m?.4m board price in 10-20 yuan. And mahogany and poplar will be cheaper. Now used in home decoration is mainly veneer plywood, that is, in the factory has been very thin solid wood veneer pasted on the plywood. Veneer plywood is easy to use, the price is cheaper than buying your own veneer for the construction team to paste. 5, melamine double paste board, not afraid of water and fire, this board on both sides of the bright crystal, very hard, not afraid of water and fire, mainly used in furniture and cabinets. The price is more expensive, 1.2m?.4m specifications of the board ranging from 80 yuan to 140 yuan per sheet. 6, veneer panels, manufacturing and the same effect as solid wood Veneer panels are made of wood grain obvious high-grade wood rotary cut veneer, very thin, the thinnest is only 0.3mm, thick, but also only 2-3mm. common veneer color from light to dark, cherry, maple, white beech, red beech, ash, white oak, red oak, teak, rosewood, walnut, white shaded wood, red shaded wood and so on tens of varieties of inexpensive. Large areas of use, it is best to buy directly from the veneer three plywood. If in order to achieve a unique effect, the veneer will be used in the local use alone, it requires a higher level of craftsmanship. Buy moisture content standards, treated wood When the moisture content of wood is higher than the environmental balance of the moisture content (the average annual moisture content of the Beijing area is 11.4%), the wood will dry and shrink, and vice versa, will absorb moisture and expand. The main reason for cracking and deformation of wood is that the moisture content is too high or too low. Qualified wood needs to go through a high temperature steaming and drying process in the factory to finally reach the local moisture content level. Therefore, the moisture content of wood is particularly important. Experts remind: don't try to cheap Experts tell us: don't try to cheap, very low price of the materials sold are usually shoddy and formaldehyde seriously exceeded the standard material. It is best to buy in the formal market, where the import channels are more secure. Buy branded materials. As wood is the main material in home decoration, the number of purchases is large, be careful when buying, it is best to take an experienced person or a professional buyer to go. You can also entrust the decorative company to buy, one is that they have a stable quality of supply units, the price may be lower, and the second is that once the quality of the problem, the responsibility is clear, the problem is good to solve.
