OSB is the abbreviation of oriented strand board in English, which is also translated into OSB in China. OSB is a new material from Europe. It is made of 100% logs, peeled, sliced, and processed along the grain direction into 40 mm120 mm, 5 mm-20 mm wide, 0.3 mm-0.7 mm thick wood chips. After high temperature drying, screening, adding high-performance adhesive and waterproof agent, it is arranged in layers according to its warp and weft direction, and made under high temperature and high pressure. OSB, through modern high-tech means, uses solid wood lamination technology and "zero formaldehyde" process to deeply process wood, which not only retains the natural characteristics of wood, but also endows OSB board with more excellent characteristics than solid wood.
The advantage of the OSB:
1. It has high physical and mechanical properties, compact structure and high strength
2. It has the triple characteristics of anti deformation, anti stripping and anti warping
3. Anti corrosion, moth proof, deformation resistant, flame retardant
4. Completely waterproof, can be permanently exposed to natural environment and wet conditions
5. Formaldehyde emission is very low, which is a real green environmental protection product
6. Strong nail holding force, easy to saw, nail, drill, open wood groove, plane, file or sanding
7. It has excellent heat insulation, sound insulation effect and good painting performance.
Compared with the traditional plywood, OSB has the advantages of small linear expansion coefficient (not easy to deform), good stability, uniform material and high screw holding force; because its shavings are arranged in a certain direction, its longitudinal bending strength is much larger than that of the transverse, so it can be used as structural material and stress component, and its strength is higher than that of the traditional plywood.
