The Difference Of Plywood Compared With OSB Plate
- Nov 19, 2018 -

OSB plate is to trail, thinning, wood core as raw materials, through special equipment processing growth of long planer (generally 40-100mm long, 5-20 mm wide, 0.3-0.7 mm thick), by deoiling, drying, sizing, directional paving, hot pressing molding and other processes made of a directional structure plate. Its surface planer is arranged vertically, and the core layer planer is arranged horizontally. This crisscross arrangement reorganizes the wood texture structure and completely eliminates the influence of the internal stress on the processing, making it extremely easy to process and moisture-proof.

As a result of the OSB internal for the directional structure, no joints, no gaps, cracks, the overall uniformity is good, the internal bonding strength is extremely high, so both the central and edge have the ordinary plate can not be compared with the super strong grip ability.  "Osb" compared with plywood, MDF and joinery plate, its line expansion coefficient is small, good stability, uniform material, high grip screw force; Because its shavings are arranged in a certain direction, its longitudinal bending strength is much larger than the transverse, so it can be used as a structural material, but also as a force member. In addition, it can be like wood sawing, sand, planing, drilling, nailing, filing and other processing, is the building structure, interior decoration and furniture manufacturing of good materials.

The disadvantage is that the thickness stability is poor, mainly due to the size of the shavings, the paving process of the shaving direction and angle can not be guaranteed to be completely horizontal and uniform, will form a certain density gradient, the thickness stability has a certain impact.
