OSB board is made of small-diameter wood, thinning wood, and wood core as raw materials. Long-length shavings are processed by special equipment, generally 40-100mm long, 5-20mm wide, and 0.3-0.7mm thick. After deoiling, drying, and applying It is a kind of directional structural board made by the processes of glue, directional paving, and hot pressing. The size of the flakes is different, the specification span is enlarged, that is, the size of the flakes is not centralized and uniform, the plane tensile strength after paving is low, and the water absorption thickness expansion rate is high. The shavings are limited by the size of the small-diameter wood, and most of them are small-sized shavings, which have a larger specific surface area, which leads to a higher amount of glue and high production costs.
