OSB borad

OSB board

It's a synthetic wood." The source of OSB - the scientific name of "OSB board" is OrientedStrandBoard (0SB), which is a new type of board rapidly developed in the world from Europe in the 1970s and 1980s. The application of "OSB board "(also known as "Egg board ") in furniture has been unprecedented development, many large furniture companies have begun to use "OSB" to make furniture, the reason why it is liked by consumers is formaldehyde-free release, and strong and durable, and furniture made of medium density fiberboard is light weight and better flatness.

Material

OSB board is a kind of directional structural board made of small wood, thinning wood and wood core as raw materials, processed by special equipment to grow long planer (generally 40-100mm long, 5-20mm wide, 0.3-0.7mm thick), by deoiled, drying, sizing, directional paving, hot pressing and other processes.

The surface planing is arranged lengthwise, and the core planing is arranged transversally. This criss-cross arrangement reorganizes the wood texture structure, completely eliminates the impact of wood internal stress on processing, and makes it have extraordinary processability and moisture resistance. Because the OSB is oriented inside the structure, no joint, no gap, crack, the overall uniformity is good, the internal combination strength is extremely high, so both the center and the edge have the ordinary plate can not match the super nail grip ability.

The raw materials of "OSB" are mainly soft needles, small path wood of broadleaf trees, fast-growing thinning wood, such as eucalyptus, fir, poplar thinning wood, etc., from a wide range of sources, and can be manufactured into large panels (such as 8×32 feet or 12×24 feet). The manufacturing process is mainly to slice a certain geometric shape (usually 50 mm -80 mm long, 5 mm -20 mm wide, 0.45 mm -0.6 mm thick) through drying, sizing, directional paving and hot press forming. The technical difficulty is high, the equipment investment is relatively large, mainly imported equipment, more than several billion, a billion investment. At present, China's "OSB" manufacturing technology and equipment production capacity are far behind North America and Europe, the main "OSB" market is also mainly dependent on imports.

Compared with plywood, MDF and joinery board, "OSB" has low linear expansion coefficient, good stability, uniform material and higher screw holding force. Because its shavings are arranged in a certain direction, its longitudinal bending strength is much greater than that of the transverse, so it can be used as a structural material and can be used as a force member. In addition, it can be sawed, sanded, planed, drilled, nailed, filed and other processing like wood, and is a good material for building structure, interior decoration and furniture manufacturing. The disadvantage is that the thickness stability is poor, mainly due to the size of the shavings, the direction and Angle of the shavings in the paving process can not ensure that the level and uniformity are completely, and a certain density gradient will be formed, which has a certain impact on the thickness stability.

The advantage of no formaldehyde release is accepted by the market as the most promising wood-based panel in the future, "OSB" has a broad space for use and development. It is the advantage of no formaldehyde release that the market looks at, which can be mainly used for: floors, walls and roofs, I-beams, structural isolation panels, packing cases, cargo trays and storage boxes, commodity shelves, industrial desktop, broadleaf floor core, air baffle and guardrail, decorative siding, precast yard concrete molding, container floor, bowling alley, etc. Processed to replace joinery board, plywood, plywood, building formwork, fire board, decorative board and MDF. Solid wood flooring and keel between the lining board, or made of composite wood flooring substrate. Structural plate for furniture and kitchenware. Lining board, interior panel, insulation board, sound-absorbing board, ceiling board, wall board for building construction. Construction retaining board, ditch formwork, cushion board, etc. After the "OSB" surface is pasted on one side, it can be used for plain board, drawer bottom, box, box, cabinet divider, floor board, bed board, etc., for furniture manufacturing.

  Foreground

  OSB chemical Kingdom - Germany, the adhesive used has always maintained a leading position in the world, the formaldehyde release of the finished product is lower than the highest European standard (European E0 standard), because the MDI adhesive used and the process is formaldehyde free (but the wood itself contains traces of formaldehyde, which is negligible), so it can be comparable to natural wood. OSB is currently the world's fastest growing plate, in North America, Europe, Japan and other developed countries have been widely used in construction, decoration, furniture, packaging and other fields, is a joiner board, plywood upgrade products. The market price of OSB is also comparable to high-end large core boards, and whether it is environmental performance or physical characteristics, OSB has comparable good performance. It is closer to the joinery board than the pine board. In the field of steel frame construction, the so-called "Canadian" building construction, the use of OSB board is irreplaceable.

OSB board came out in the 1970s, is Europe and the United States international common use of decorated wood as basic materials. OSB board scientific name directional structure particleboard, OSB board environmental performance is better (must be imported products, formaldehyde content is very low, far below the European standard E1 level. Domestic manufacturers produce this plate is also called OSB, that basically can only reach the domestic own E1 level standard, just like Alpi AOSong density board, many of the domestic medium density board are called AOSong board, is a cottage, ha ha); Side to eat nails, the joinery board is slightly stronger, after all, the joinery board is the material of the log plate, which belongs to the Chinese people's favorite solid wood (solid wood slats arrangement); In summary, it is recommended to use imported OSB board, after all, people's living standards have improved, higher requirements for environmental protection.
