Oriented particleboard is one of the new varieties of particleboard. When the particleboard is paved and formed, the upper and lower surface layers of the oriented particleboard arrange the glue mixed particleboard longitudinally according to its fiber direction, while the core layer particleboard arranges horizontally to form a three-layer structure board embryo, which is then hot pressed into the oriented particleboard. The shape of oriented particleboard is required to be larger in length and width, and its thickness is slightly thicker than that of conventional particleboard. The methods of directional paving include mechanical orientation and electrostatic orientation. Mechanical orientation is suitable for large particleoriented pavement, and electrostatic orientation is suitable for small particleoriented pavement. The application field of oriented Particleboard in China is relatively narrow. At present, China's wood structure housing is in the initial stage of development. Due to the limitations of people's traditional housing concept and economic level, the development of oriented Particleboard in building materials application is hindered to a certain extent.
Oriented particleboard is mainly used in construction, transportation, packaging and other fields abroad. At present, in North America, OSB has been widely used in wallboard, floor, floor, etc. In recent years, OSB, together with LVL, has been used as load-bearing structural material for I-beam in construction industry. As an exposed packaging material, oriented particleboard can be used to make pallets, packaging boxes, storage boxes, container floors, etc., and can be exempted from inspection and quarantine. In the transportation industry, oriented particleboard is used for car panel, car floor and so on.
