1, solid wood panel As the name implies, solid wood panels are made of wood made of complete wood. These boards are durable and have natural lines, making them the best choice for decoration. However, due to the high cost of this kind of sheet, and the high construction process requirements, there is not much to use in decoration. Solid wood panels are generally categorized according to the physical name of the panel and there is no uniform standard specification. 2, splint splint, also known as plywood, row commonly known as fine core board. It is made by hot pressing three or more layers of one-millimeter thick veneer or sheet glue. It is the most commonly used material for hand-made furniture. Plywood is generally divided into three kinds of plates, 5 PCT board, 9 PCT board, 12 PCT board, 15 PCT board and 18 PCT board of six kinds of specifications (1 PCT is 1 mm). 3, decorative panel decorative panel, commonly known as panel. It is a veneer with a thickness of about 0.2mm, and a veneer with a single-sided decorative effect. It is a special way of plywood, with a thickness of 3%. Decorative panels are currently an advanced decoration material that is different from the oil mixing practice. 4, blockboard Blockboard, commonly known as Daxinban within the line. The core board is made by splicing wood boards. The two surfaces are solid boards made of glued wood veneers. The price of the big core board is lower than that of the fine core board. The vertical direction (distinguishing the core material) has poor flexural strength, but Lateral bending compressive strength is higher. 5. Particle board Particle board, also known as particle board, is a general term for thin boards that use wood scrap as the main raw material, and applies glued materials and additives. According to the pressing method, it can be divided into two types: extruded particle board and flat pressed particle board. The main advantage of this kind of sheet is that the price is extremely cheap. The disadvantages are also obvious: the intensity is extremely poor. Generally not suitable for making larger or mechanical requirements of furniture. 6, MDF fiberboard density board, also known as fiberboard. The artificial board made of urea-formaldehyde resin or other suitable adhesives is a fiberboard made from plant fibers such as wood, bamboo or other crop stems, and the fiberboard is divided into hardness fiberboard, semi-hard fiberboard, and soft fiberboard according to different properties. Three kinds. According to their different density, divided into high-density board, medium-density board, low-density board. MDF is also easy to rework because of its soft and impact resistance. In foreign countries, MDF is a good material for making furniture, but due to the fact that the national standard for height plates is several times lower than international standards, the quality of use of MDF in China needs to be improved. 7. Fireproof board Fireproof board is made of silicon or calcium material as the main raw material, and a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives mixed by autoclave technology made of decorative plates. It is a new type of material that is being used more and more. Its use is not only due to fire protection. The construction of the fire board requires a relatively high requirement for glue sticking, and the fire board with better quality is also more expensive than the decorative panel. Fire board thickness is generally 0.8mm, 1mm and 1.2mm. 8, melamine board melamine board, full name is melamine impregnated film decorative wood-based panels. The paper is made of melamine resin adhesive soaked in paper with different colors or textures, and then dried to a certain degree of curing, and it is paved on the surface of particleboard, medium-density fiberboard or hardboard, and the hot-pressed decorative board. The melamine board is a wall decoration material. At present, it is inappropriate to use melamine boards to fake composite floors for floor decoration. 9, gypsum board Gypsum board is a building gypsum as the main raw material, mixed with appropriate amount of light aggregates and admixtures constitute the core material, and in the protection of the tissue paper firmly bonded together building board.
Purchase plates required courses to buy plates to learn to identify, see, touch. To identify the grade on the product. Different grades of commercial products have different formaldehyde emissions. E1-grade commercial products have a smaller formaldehyde emission and can be used directly in indoor areas. E2-class commodity finishes have been treated and formaldehyde emission is relatively large. It depends on whether the seams are tight and the cracked sheet is easily deformed. The smoothness and thickness uniformity of the sheet are touched by hand. The high quality blockboard is generally treated with sanding on both sides and has a uniform thickness and a smooth surface. In addition, when you go to the market to buy plates, it is best to provide their own ruler to accurately measure the thickness of the plate. Such as blockboard is divided into 15 mm, 18 mm standard thickness; multilayer plate is divided into 3 mm, 5 mm, 9 mm, 12 mm, 18 mm standard thickness, the error is generally not allowed to exceed 0.5 mm. Important Note: The first step in buying timber is to see if it is environmentally friendly. According to regulations, the amount of formaldehyde released from indoor building materials must be less than or equal to 1.5 milligrams per liter. If it exceeds 5 milligrams per liter, it will be substandard. Secondly, look at the moisture content of wood. When the wood moisture content is higher than the equilibrium moisture content of the environment, the wood will dry and shrink, otherwise it will absorb moisture and expand. The main cause of dry cracking and deformation of wood is the high or low moisture content. Finally, when buying, don’t just buy cheaper materials. The materials sold at low prices are usually materials that are heavily shoddy and have excessive formaldehyde levels. They should be purchased in the formal market, and it is best to buy branded plates. Many consumers who have already been decorated have such "experiences": from the outside, they are flat, clean and big core boards, but when they are sawed, they are full of things that are not so good, black dead wood, dead wood or many big ones. Gap, some can even see a group of eggs, hand pinch, issued a "squeak" break. The "doorway" in home decoration is well-known, among which the building materials, especially the artificial boards that are inseparable from the decoration, are the most "patterns". Into the plate market, a block board mountain everywhere, blockboard (daxin board), fiberboard, particleboard a variety of brands, a variety of price everything. On the face of it, non-industry people will not be able to see what the mystery is, the same specifications, similar color, how is the price so much? Take Daxin board as an example, the same brand with the same level of product is divided into several types, the price ranging from 80 to 110 yuan. What is different about this? Luo Station Chief of Beijing Municipal Quality Supervision and Inspection Station for Wood Furniture said that firstly the manufacturers of blockboards are different, and the production cost, product quality and materials used are not the same, and the prices are certainly different. In addition, the different veneer materials on the surface of the plate will also affect the price of the entire plate. In order to reduce prices, some manufacturers use inferior materials such as dead wood and dead wood in the middle of the blockboard, and even more, sawdust is filled in between. In addition, there are many misunderstandings in the purchase of plates by consumers themselves. 1, "cutting the edge of a clean plate must be good." This statement is wrong. Meng Meng, a home improvement company who deals with plates all the year round, said that the more careful the plates are, the more careful the consumers are. The edges are produced when the machine is sawing. Good plates generally do not need to be “reprocessed†and often have a lot of hair. You children. However, the quality of the board
