[ Chinese wardrobe net ] The wardrobe sheet is the sheet used to make the wardrobe. There are many kinds of wardrobe plates, such as particle board, MDF, moisture-proof board, large core board, fir board, multi-layer solid wood board, etc. For detailed classification of wardrobe sheets and knowledge of the advantages and disadvantages of each board, please see below. 1, particle board Particleboard (also known as "solid wood particle board") is a piece of wood or other wood fiber material that is cut into a certain size as a raw material. After drying, it is mixed with an adhesive, a hardener and a waterproofing agent under heat, pressure and a certain temperature. An artificial board that has been pressed. Particleboard appearance advantages The inside is a granular shape with a cross-displacement structure, the performance in each direction is basically the same, and the lateral load-bearing capacity is good. In the production process, the amount of glue used is small and the environmental protection factor is relatively high. The surface is flat, the texture is realistic, the weight is uniform, the thickness error is small, the pollution is resistant, the aging is resistant, the appearance is beautiful, and various veneers can be performed. The finished product does not need to be dried again, it can be used directly, and the sound absorption and sound insulation properties are also good. Chipboard shortcomings The interior is granular and not easy to mill. The edge is rough, easy to absorb moisture, and it is easy to cause violent teeth when cutting the board. Therefore, some processes require higher processing equipment; it is not suitable for on-site production. 2, MDF MDF (also known as "fibre board") is made of wood materials such as trunk materials, branches and other wood materials or other plant fibers, which are thermally ground (milled into powder), sized (urea resin or other suitable adhesive), dried, An artificial board made by hot pressing after paving. MDF appearance advantages Various veneer, adhesive film, veneer, light metal sheet and other materials can be glued on the surface of the MDF; various paints and paints can also be applied to the MDF, and the effect is very beautiful. The hard MDF is punched and drilled, and can also be made into an acoustic board. The surface is smooth and flat, the material is fine, the performance is stable, the edge is firm, and the shape is easy to avoid, causing problems such as decay and insects. Excellent physical properties, good nail holding power, uniform material, no dehydration problems. MDF disadvantage If it is not moisture-proof, it will swell when it sees water, and it will be deformed for a long time. 3, moisture-proof board The moisture-proof board is to add a certain proportion of moisture-proof particles to the particle board substrate, so that the degree of water swelling of the board is greatly reduced. Moisture plate appearance advantages In addition to the advantages of particle board, there is also a prominent advantage is moisture. However, it should be noted that the moisture-proof board and the ordinary particle board are immersed in water, and the expansion ratio is the same. The so-called moisture-proof only acts on the moisture in the air. Damp proof board All the shortcomings of particleboard, the moisture-proof board has. 4, large core board The large core board (also known as "blockboard" is made of two pieces of veneer laminated in the middle of the board. The middle board is made of high quality natural wood board after heat treatment (ie drying in the drying room). The specification of the wooden strip is made up of the jigsaw machine. The two sides of the spliced ​​wooden board are covered with two layers of high-quality veneers, and then made by cold and hot press. The total of the two sides of the large core board is glued. The thickness shall not be less than 3mm. The corner defects of all kinds of large core plates shall not exceed 5mm in the nominal width and shall not exceed 20mm in length. Large core board appearance advantages The clamping force is good, the strength is high, and it has the characteristics of firmness, sound absorption, heat insulation, etc., and the water content is not high, between 10% and 13%, and the processing is simple. The plate of the machine is subjected to a large pressing force, the gap is extremely small, the splicing is flat, the bearing capacity is uniform, long-term use, compact structure and deformation. Big core board disadvantage Poor moisture resistance. Hand-made is to manually insert the wooden strip into the splint. The wooden strip is subjected to less pressing force, uneven splicing, large gap, poor nail holding force, and cannot be sawed and processed. It is only suitable for sub-projects of partial decoration. Such as the solid wood floor cushion board and so on. 5, fir board The fir board is a large-format thick plate that is made of short and small materials and is widened by fingers. It generally uses high-quality wood (currently more fir, so commonly known as fir board) as a substrate, after high-temperature degreasing and drying, finger jointing, jigsaw, sanding and other processes. Fir board appearance advantages After high-temperature degreasing treatment, it is made into a warp knot; it is durable, no insects, no deformation, and also emits a light scent of wood. It is a natural plate with original flavor, clear wood grain, natural and generous, and has the natural simplicity of returning to nature. The amount of glue used is only seven tenths of wood board, and it is environmentally friendly. The surface is sanded and thickened, smooth and smooth, and the surface does not need to be attached to the panel when making the wardrobe, saving labor and materials, and economical. Fir board defects Poor quality of the fir board, moisture content is not up to standard, easy to deform, cracking after a long time. 6, multi-layer solid wood board It is made of three or more layers of veneer or thin board glue. The splint is generally divided into three specifications: 3 PCT, 5 PCT, 9 PCT, 12 PCT, 15 PCT and 18 PCT. Multi-layer solid wood panel appearance advantages The deformation is small, the strength is large, the internal quality is good (the hole is small after the sawing, the layer is not layered), and the flatness is good. The structure has good stability, is not easy to be deformed, can properly adjust the indoor temperature and humidity, and the surface layer solid wood skin material has the texture and feel of natural and real wood. 7, Australian pine board Australian pine board (also known as "oriented structural particle board"), Australian pine board is an Australian imported medium density board. Australian pine board appearance advantages With a high internal bond strength, each board's surface is highly sanded to ensure a first-class finish. The smooth surface makes it easy to stain, clean, color, spray and inlay and cover in various forms. Not only the surface of the board has the strength and various advantages of natural wood, but also avoids the defects of natural wood, which is an upgraded product of plywood. It has a well-balanced structure with smooth edges and excellent mechanical properties. Australian pine board shortcomings Without nails, it has a good grip on the screws, but the nails that are hammered into the hammer have good performance. 8, Ou Song board Ou Song board (also known as "oriented structure particle board"), using fast-growing materials, thinning materials (such as pine, poplar, etc.) as raw materials, processed by special equipment to grow 40-100mm, width 5-20mm, thickness 0.3-0.7mm The flakes are made by drying, screening, sizing, directional paving, continuous hot forming, etc., a new type of plate that has developed rapidly from Europe in the 1970s and 1980s. Ozon board advantages Low formaldehyde release, durable and durable, the furniture is lighter and flatter. The interior is oriented structure, no joints, no gaps, cracks, good overall uniformity, and high internal strength. Therefore, both the center and the edge have the superior nail holding ability that ordinary sheets cannot match. Ozon board fault Like the Australian pine board, the Ou Song board does not eat nails. It has a good grip on the screws, but the nails that are hammered into the hammer have the same performance.
