The plates on the market are mainly divided into:
Low-density fiberboard, medium-density fiberboard, high-density fiberboard, particleboard, solid wood particle board, solid wood multi-layer board [melamine board], finger-jointed solid wood board, ecological board, etc.
Â
1 low density fiberboard
It is a sheet made of wood shavings made of wood or vegetable fiber with a large amount of urea-formaldehyde compound and excipients. Its density is less than 450 kg / cubic meter, the fiber particles are larger, the internal structure is not uniform, the strength is relatively insufficient, and the weight is light.
Â
2 medium density fiberboard
It is a kind of plate which is made by using wood fiber or other plant fiber as material, adding urea-formaldehyde glue and pressing under high temperature and high pressure. The density is between 450-880 kg/m3, the fiber particles are moderate, the internal structure is uniform, the strength is large, the self-weight is moderate, but the nail holding power is insufficient, which is not conducive to the secondary disassembly of the plate furniture, and the urea-formaldehyde glue is easy to volatilize the urea. And formaldehyde, environmental performance in general.
Â
3 high density fiberboard
It is a plate which is made by pressing wood fiber and wheat straw plant fiber into a binder under high temperature and high pressure conditions. Its density is about 680-850 kg / cubic meter, the fiber particles are small, the internal structure is uniform, the strength is large, the weight is large, but the tensile and bending resistance is poor.
Â
4 particle board
It is a thin plate made of wood scrap, wood shavings, small-diameter wood branches and bark as main raw materials, and then added with glue and additives. According to the pressing method, it can be divided into two types: extruded particle board and flat particle board. The raw materials of such plates are not uniform in size, but the strength is poor, but the plasticity is high and the price is relatively cheap. Generally, it is not suitable for making larger or mechanically demanding furniture.
Â
5 solid wood particle board
It is made by crushing a single wood species into a granular state as a main raw material, and then adding a natural resin glue to be pressed. The density is relatively high, the density of the board is low, and the self-weight is moderate. Because the interior is a single wood particle structure, the tensile strength and bending resistance are good, generally used for high-grade panel furniture, and the environmental protection performance is good.
Â
6 times solid wood board
The full name is a wood-based panel covered with melamine impregnated film paper. It is a plate which is made by immersing paper of different colors or textures into a melamine resin adhesive, drying it to a certain extent, and laying it on the surface of particleboard, medium density fiberboard or hard fiberboard, and hot pressing.
The conditions for the production of triamine plates are: pressure 900 tons - 1000 tons; temperature 200 degrees; time 40 seconds;
The main parts of the furniture are the outer and inner sills; the thickness of the materials used is 80 g and 120 g; the appearance can be divided into two types: pockmark and plain.
Melamine is a very common flame retardant. The material immersed in melamine will sublimate or decompose to form a flame retardant gas when heated, and it needs to absorb a large amount of heat when it is decomposed. Therefore, the most commonly used melamine is to make fireproof board. Therefore, the melamine board is resistant to high temperatures.
Melamine paper is directly coated on the surface of wood-based panels such as particleboard and fiberboard without adhesive, and the surface after lamination does not require paint treatment, so it is environmentally friendly.
In addition, melamine paper surface texture printing uses water-soluble inks, color and texture are very rich, and the decoration is very strong. Based on these advantages, the application of triamine plates is becoming more and more extensive. For example, the European EGGER plate is a melamine veneer with a solid wood particle board.
Â
7 finger jointed wood panels
Finger jointed wood panels are wood panels made from complete wood. These plates are sturdy and durable, and the texture is natural. However, due to the high cost of such panels and the high construction process requirements, there are not many uses in the decoration. Solid wood boards are generally classified according to the physical name of the board, and there is no uniform standard specification. In addition to the use of solid wood panels for floors and door fans, the panels we use are generally artificially machined panels.
Â
8 splint
The splint, also known as plywood, is commonly known as a thin core board. It is made of three or more layers of one millimeter thick veneer or sheet adhesive. It is the most commonly used material for hand-made furniture. The splint is generally divided into three specifications of 3 PCT, 5 PCT, 9 PCT, 12 PCT, 15 PCT and 18 PCT (1 PCT is 1 mm).
Â
9 blockboard
Blockboard, commonly known as large core board. The large core board is made up of two sheets of veneers bonded together in the middle. The price of the large core board is cheaper than that of the thin core board, and the vertical direction (differentiated by the core material direction) is inferior in bending strength, but the lateral bending strength is high.
Â
10 wood composite panels
Wood-plastic panels are made of hot-melt plastics, including polyethylene, polypropylene, and polyvinyl chloride as adhesives. Wood powders such as wood, agricultural plant straws, and agricultural plant shells are used as fillers, and advanced process equipment is used. Produced high-tech products.
Â
11 ecological board
The eco-board, also known as the paint-free board, is made by affixing high-grade stencil on the blockboard. It has high flexural strength and flexural strength. At the same time, the color and texture of the stencil are rich, and the home decoration can be diversified. The choice, while the new technology product negative ion ecological board, can also release negative ions, absorb formaldehyde, purify the air, give consumers a green and environmentally friendly home environment, is the first choice for home improvement panels.
