Origin and development of European pine board

Ospine board, whose scientific name is OrientedStrandBoard (0SB), is a new type of board from Europe and developed rapidly in the 1970s and 1980s. At present, it is the fastest developing board in the world, and it has been widely used in the fields of architecture, decoration, furniture, packaging, etc. in developed countries such as North America, Europe and Japan. It is an upgraded product of blockboard and plywood. The application of "OSB Orson Board" in furniture has been developed unprecedentedly, and many large furniture enterprises have begun to use "Orson Board" to make furniture. The reason why it is popular among consumers is that it has no formaldehyde emission, and it is durable, lighter in weight and better in flatness than the furniture made of medium density fiberboard. Composition It is an oriented structural board made of small-diameter wood, thinning wood and wood core as raw materials, which are processed into 40-100mm long, 5-20mm wide and 0.3-0.7 mm thick by special equipment, and processed by deoiling, drying, sizing, directional paving, hot pressing and other processes. The surface plane pieces are arranged vertically, and the core plane pieces are arranged horizontally. This crisscross arrangement reorganizes the wood texture structure, completely eliminates the influence of wood internal stress on processing, and makes it have extraordinary processability and moisture resistance.

Because the interior of the European pine board is directional structure, without joints, gaps and cracks, with good overall uniformity and extremely high internal bonding strength, both the center and the edge of the board have superior nail-holding ability that ordinary boards can't match. B performance and use of ospine board 1 performance: it has good stability and high screw holding force. The raw materials of "European pine board" are mainly small-diameter wood with soft needles and broad-leaved trees, fast-growing thinning wood, etc., such as eucalyptus, Chinese fir, poplar thinning wood, etc., which come from a wide range of sources and can be made into large-scale panels (such as 8×32 feet or 12×24 feet). The manufacturing process is mainly to dry, glue, directionally pave and hot press the planer with a certain geometric shape (usually 40mm-100mm long, 5mm-20mm wide and 0.3mm-0.7mm thick). The technical difficulty is high, and the equipment investment is relatively large, mainly imported equipment, mostly hundreds of millions or billions of dollars. Compared with plywood, medium density fiberboard and blockboard, "European pine board" has smaller linear expansion coefficient, better stability, uniform material and higher screw holding force. Because its wood shavings are arranged in a certain direction, its longitudinal bending strength is much larger than that in the transverse direction, so it can be used as a structural material and a stress member. In addition, it can be sawed, sanded, planed, drilled, nailed and filed like wood, and is a good material for building structure, interior decoration and furniture manufacturing.
