① Solid wood board
Solid wood board is a wood board made of intact wood. Advantages: Sturdy and durable, with natural charm lines, is currently the most natural and environmentally friendly in furniture sheets. It is the best choice for home decoration. Disadvantages: the cost of the board is high, the process requirements are strict, the deformation is not easy to master, the cracking problem is almost unavoidable, and the fire performance is relatively less than ideal, so not many are used in the decoration. Solid wood boards are generally classified according to the actual name of the board. There is no uniform standard rule e79fa5e98193e4b893e5b19e31333337396334. Different tree species have different wood hardness. Since solid wood boards are becoming scarcer and more expensive, they are now more developed to produce high-end furniture, because various flowers and patterns can be directly carved on the board to make classic style furniture.
② Bamboo board
Bamboo plates, namely bamboo puzzles and bamboo plywood, are made by cutting, milling, cooking and carbonizing, gluing and splicing, and pressing of bamboo pieces. They are suitable for the manufacture of various furniture, handicrafts, bamboo flooring, and bamboo and wood products. Taohuajiang Bamboo Board mostly uses high-quality Nanzhu as the basic raw material. After fine processing, it not only has excellent physical and mechanical properties, but also has the advantages of small water absorption expansion coefficient, no dry cracking and no deformation. According to the texture and shape of the surface layer, Taohuajiang Bamboo Board can be divided into flat pressed bamboo board and side pressed bamboo board.
According to the color, it can be divided into natural bamboo board and carbonization, and the color formed after high-temperature carbonization treatment; according to the process structure, it can be divided into conventional bamboo board, bamboo veneer, heavy bamboo board, bamboo square material, I-shaped bamboo board, and middle-horizontal bamboo board , Bamboo skin, bamboo round bar, bamboo wire drawing, bamboo craft board, bamboo furniture board, etc.
Taohuajiang environmental protection glue (Tel glue imported from the Netherlands) is assembled into bamboo sheets of different specifications under high temperature and high pressure.
Its hardness can reach 32HB, beech is 24HB;
Density 1cm3 reaches 0.79g, beech is 0.63g;
Compressive strength reaches 1271kg / cm2, beech wood≤600kgs.
③ Plywood (plywood, fine core board)
After steaming, boiling and softening, the logs are rotated and cut into thin wood chips along the direction of the annual ring. After adding the glue, three or more layers of odd veneers are cross-bonded horizontally and crosswise and hot pressed. Advantages: The surface is natural and beautiful, retaining the beautiful patterns of natural wood. Generally, it is not necessary to paste other veneer materials when using it. As long as it is painted with paint, you can get an excellent appearance. It has good strength and toughness, has strong nail-holding strength, is easy to process and insulate, and can make up for some of the defects naturally caused by natural wood, such as small breadth, deformation, and large differences in vertical and horizontal mechanics. The resulting furniture is lighter than other wood-based panels. Good bending resistance. Disadvantages: Therefore, it is less used for the overall material of furniture, and is generally used for the decorative parts of furniture. According to different thickness specifications, plywood is generally divided into six specifications: 3 PCT, 5 PCT, 9 PCT, 12 PCT, 15 PCT and 18 PCT. Because the plywood has the advantages of small deformation, large format, convenient construction, no warping, and good tensile mechanical properties of the transverse grain. Therefore, this product is mainly used in various plates for furniture manufacturing, interior decoration, and residential construction, followed by industrial sectors such as shipbuilding, car box manufacturing, various military, light industrial products, and packaging.
④ Blockboard (large core board)
In the middle is a core made of natural wood strips, with thin veneer glued on both sides, so it is also known as a large core board and is one of the most important materials in decoration. The price of the large core board is cheaper than that of the fine core board, that is, the plywood mentioned above. It has small density, small deformation, high strength and good dimensional stability, so it is widely used. The wood material of the middle of the blockboard is generally poplar, paulownia, fir, white pine and so on. The high-quality products are smooth and smooth, without degumming, sand damage, indentation, small thickness deviation, and no obvious hollow core after sawing.
Advantages: firm quality, sound absorption, heat insulation. In addition to some of the above, because of its simple processing technology and good nail holding ability, it is very popular to play furniture at the site of the decoration company. Disadvantages: affected by the processing technology, according to the core material direction, its vertical bending resistance is poor, and the lateral direction is better. In addition, the water content is high; the formaldehyde content is also high, and it can be used safely after treatment. Fear of moisture, avoid using it in the kitchen and toilet during construction. Many consumers choose large core boards, looking at the weight and price. In fact, the heavier the big core board, the worse the quality. Because of its heavy weight, it indicates that this board uses miscellaneous wood.
From the perspective of the current overall wardrobe industry, commonly used boards are particle board and density board (medium density board). Therefore, we will focus on the detailed dissection of these two materials.
⑤ MDF (fiberboard)
It is an artificial board made by processing wood or non-wood plants into fibers (after cutting, infiltration, pulping) and adding the adhesive used after high temperature and high pressure. As the name implies: the density is higher than that of ordinary plates, and it is divided into high-density plates, medium-density plates, and low-density plates according to their density. Commonly used is MDF. Advantages: Weak performance is excellent, the material is uniform, and there is no dehydration problem. The performance of MDF is close to that of natural wood, but without the defects of natural wood. The internal structure is not easy to warp, crack and small deformation, suitable for various machining. The surface is smooth and smooth, the material is fine, the edges are firm, and it is easy to shape, to avoid problems such as decay and moth-eaten. High bending strength and impact strength. The density board can be shaped like sculptures.
Disadvantages: The shortcomings are as obvious as its advantages, moisture resistance, poor nail holding ability, and difficult to fix. From the perspective of moisture resistance, if a medium density board is soaked in water, it will expand like bread. However, when buying, pay attention to whether expansion is too fast or too slow. It is likely to be high-density board and low-density board (these two kinds of boards are now very rare due to obvious defects). The processing precision and process requirements are high, and the cost is high; because of its high density, it must be cut with a precision saw, and it is not suitable for processing on the decoration site. In foreign countries, MDF is a good material for making furniture, but because our standards for MDF are several times lower than international standards, the quality of MDF in China needs to be improved. China's commonly used medium-density board has several specifications of 3%, 5%, 9%, 12%, 15%, 18%, 25%.
⑥ Particleboard (particle board)
It is a plate made by pressing waste materials from wood harvesting and processing or wood shavings of other plants, adding rubber or other auxiliary materials. The pressing method can be divided into two types: extruded particle board and flat pressed particle board. Advantages: good sound absorption and sound insulation performance. It can be used as sound-absorbing building components such as sound insulation siding doors. The expansion rate of the board is low, and the thickness error of the board surface is small. There are sufficient raw materials, low cost, good quality and strength, easy to cut and process. It is one of the main materials of cabinet cabinets. The cost is cheaper than MDF, and the formaldehyde content is much lower than the large core board. It is one of the most environmentally friendly artificial board.
Disadvantages: slightly poor nail holding ability. The quality difference between different products is large, and it is difficult to distinguish; the bending resistance and tensile resistance are poor; the lower density is easy to loosen. Therefore, it is generally not suitable for making larger or mechanical furniture. In terms of modeling is not as good as MDF. There are many specifications of particle board, the thickness is from 1.6 to 75 mm, with 19 mm as the standard thickness, and commonly used thicknesses are 13, 16, 19 mm. Of course, many specifications can now be customized. In the overall wardrobe industry, many specifications are consistent with MDF. For consumers, the names of particleboard, fiberboard, blockboard and other wood-based boards are familiar.
