The
The plate is an indispensable decoration material in the home decoration, but whether the owners know which plates need to be used for the decoration and whether they understand the plate. If you do not understand it does not matter, Xiao Bian through this article to introduce everyone to introduce the types of plates and how to buy the plate does not fall into the procurement errors, I hope you can help the first time to decorate the owners do not understand the market.
Introduction of board materials
1, solid wood board
As the name suggests, solid wood panels are wood panels made from intact wood. These boards are durable and natural in texture and are the best of the best. However, due to the high cost of this plate, and the high construction process requirements, it is not used in China. Solid wood panels are generally classified according to the physical name of the panel and do not have the same specifications. At present, in addition to the use of solid wood panels for floors and doors, the plates we use are generally artificially processed.
2, plywood plate
Plywood, also known as plywood, commonly known as the 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. The splint is generally divided into three kinds of specifications: 3 PCT, 5 PCT, 9 PCT, 12 PCT, 15 PCT, and 18 PCT. Panels, commonly known as veneer panels. The solid wood board is precision-sliced ​​into thin and thin veneer with a thickness of about 0.2 mm, and a sheet with a single-sided effect is formed by a sticking process using a cleat as a base material. It is a special way of plywood, with a thickness of 3%.
3, density plate
MDF, also known as fiberboard. The artificial board made of urea-formaldehyde resin or other compatible adhesives based on wood fiber or other plant fibers is classified into high-density board, medium-density board, and low-density board according to the density. MDF is also easily reprocessed due to its soft and impact resistance. In foreign countries, MDF is a good material for making furniture, but because the national scale on the height of the plate is several times lower than the international scale, the quality of the use of MDF in China is still to be improved.
4, particle board plate
Particleboard is a thin plate made of wood scraps as the main raw material, then infiltrated with glue and additives are pressed. 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 very significant: the intensity is extremely poor. Generally not suitable for the production of larger or mechanical requirements of furniture.
5, blockboard plate
Blockboard, commonly known as. It is composed of two veneers that are laminated together by pressure. The price is cheaper than the fine core board, its vertical bending strength is poor, but the lateral bending strength is high.
6, fire board plate
Fire board is made of silicon material or calcium material as the main raw material, and a certain proportion of fiber materials, lightweight aggregates, adhesives and chemical additives mixed, made by autoclave technology. 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 is required for glue sticking, and the fire board with better quality is also more expensive than the panel. Fire board thickness is generally 0.8mm, 1mm and 1.2mm.
7, Aggrek plate
Aggrek sheet is a specially processed plexiglass, which has the reputation of "plastic queen". It has a good color and high transparency. Its advantages are excellent weather resistance, good transparency and good plasticity. Disadvantages are low hardness, poor heat resistance, and low elongation. Therefore, they are easily cracked, brittle, easily deformed, and unstable in color, and are prone to fluffing during use. In addition, it also contains substances that are harmful to the human body.
8, melamine plate sheet
Melamine board, the full name is melamine impregnated film coated wood-based panels, is a wall material. The manufacturing process consists of immersing papers with different colors or textures into melamine resin adhesives, drying them to a certain degree of curing, and paving them on the surface of chipboard, medium density fiberboard or hardboard, and hot pressing them. board.
How to buy plate
(1) Nowadays, everything is concerned with environmental protection. We must first consider environmental protection when we choose materials.
(2) Look at the surface of the board for obvious flaws. The surface of the decorative board should be smooth, free of burrs and slicing knife marks, no glue penetration phenomenon, and board surface contamination (such as local blackening and yellowing). Try to pick out the surface of the board without cracks, cracks, knots, and clips. The natural warpage of the entire board should be as small as possible for the resin capsules and the gum lanes, so as to avoid the phenomenon of sand penetration revealed by the base material due to improper operation of the sanding process.
(3) Recognize the difference between veneer veneer and natural wood veneer veneer. The former plate texture is basically a straight texture, and the texture pattern is regular; the latter plate is a natural wooden pattern, and the natural variability of the texture pattern is relatively large and irregular.
(4) inspection of the appearance of the sheet. The appearance of decorative panels should have a good aesthetic sense. The materials should be fine and uniform, with clear color and beautiful wood grain. The texture of the panel boards and parquet should be arranged according to certain rules. The wood color is similar, and the seams are almost parallel to the edges of the panels.
(5) The structure of the sheet glue layer is stable and there is no open glue phenomenon. It should be noted that there should be no bulging or delamination between the veneer surface and the substrate and between the internal layers of the substrate.
Common plate purchase error
Mistakes in common plate purchase: Particleboard is more environmentally friendly than MDF
At present, most of the plate furniture on the market are particle board and medium density board, because both types of boards are made of wood after being destroyed by wood processing and mixed with adhesive. The amount of glue determines the chemical composition, that is, its environmental protection. To the extent that most consumers are very concerned about which of the two plates is more environmentally friendly. Therefore, many sales staff often mislead consumers when dumping their products. A furniture salesman told reporters when he introduced the product: “Our plates are all wood shavings in the northeast. You see, how big is this grain, and there is less glue used? Can it be the same as glue boards that are glued? More than their density board environmental protection! "Facts really are it? China Furniture Association experts told reporters:" Qualified, that is to achieve the national standard of MDF and particleboard environmental protection is the same, there is no one This is a more environmentally friendly statement." The so-called density plate usually refers to medium density board, also known as medium density fiberboard. It is a kind of man-made board made of wood or plant fibers mechanically separated and chemically treated, mixed with adhesives and water repellent, and then paved, formed and pressed at high temperature and high pressure. Its density is average, and the mechanical function is close to that of wood. An artificial plate that is more popular in the world.
The difference between particleboard and MDF is that the material of the particleboard is not completely destroyed by the broken fiber, but broken and destroyed into pellets, also known as wood shavings, and then joined by glue; and the MDF is made of wood. The raw material is completely broken up and destroyed into fibrous form and then joined with glue. The density of the particle board is similar to that of the medium density fiberboard, but because the chipboard is formed by adding the adhesive to the shavings, the density is not even, the middle is low, and the two ends are high, so the nail holding force is lower than that of the medium density fiberboard. And the surface of the MDF is finer and flatter than the particle board. However, particleboard is better in terms of moisture absorption and moisture resistance than MDF, and the price is relatively low. Therefore, it can be said that qualified MDF and particle board only have their own advantages in terms of function, and there is no one that is more environmentally friendly.
Mistakes in common plate purchase: Wood particle board is "new environmental protection product"
Because the use of plate furniture made of MDF and particle board that have not reached the national scale has caused numerous indoor pollution cases, resulting in the reputation of these two kinds of plates are not very good, so many sales staff have made new for these two kinds of plates. The name misleads consumers. The most common name is to say that the MDF is a particle board and the particle board is a particle board. Some sales staff will add the word "solid wood" to the front to indicate that they are "natural and environmentally friendly" products. A salesman from Xianghe Furniture City, a city surrounding Beijing, told reporters: “We use new products developed by our company, natural wood particle board, and absolute environmental protection.†When consumers carefully question the difference between wood particle board and solid wood The sales staff were vague and did not recognize their true identity: "The solid wood particle board is the solid wood particle and it is sure to be different from the solid wood. The plate furniture is cheap! But, you see this price, the same environmental protection thing, Solid wood furniture can be so cheap? "If consumers stroll down the road, met seven or eight sales staff say so, can not faint!
Mistakes in common plate purchase: Blockboard is a solid wood plate
Blockboard, also known as the big core board, cuts the logs into strips, splices into cores, and is finished with surface materials. Since the main materials are all solid wood, many sales staff will introduce green sheets. In fact, large core boards are artificial sheets containing adhesives.
Mistakes in common plate purchase: MDF is MDF
In the interview, the reporter discovered that many sales staff will tell you that they are using a tri-hydrogen ammonia plate when they introduced their products. When the reporter further asked what kind of sheet is, he was told: "Tri-hydrogen The ammonia board is the medium density board.†Under the misdirection of the sales staff, it is generally believed that the trihydrogen ammonia board is the medium density board, whereas the medium density board is the tri-hydrogen ammonia board.
In fact, this kind of board is a paper printed with color or imitation wood grain, soaked in melamine transparent resin, affixed to the surface of the substrate and hot pressed and formed. After the melamine resin is cured, the veneer has better physical functions such as wear resistance and scratch resistance, and has a certain resistance to fire. The sheet made of this kind of material is called tri-hydrogen ammonia sheet, and the base material is different. MDF, particle board, etc. can be made into tri-hydrogen ammonia sheet.
