Building Oriented

Oriented particle board (OSB / OSB) are high-tech material used in Wood Frame Construction, in the manufacture of furniture and different packaging. Manufacture of osb / osb panels is done by gluing large size (3-8 cm), thin chips, and upper and lower layers of the grain direction, longitudinal, and in the middle layer – cross the length of the slab. Because of the low value for the same as Oriented particle board gradually replacing plywood in many traditional areas of application. osb / osb plate is tightly pressed three-layer wood board from the large-oriented chips conifers. Appearance Oriented chipboard osb / osb clearly explains its name. Plate can be easily distinguished by an elongated chips. Oriented strand board is made up of three layers. In the outer (upper and lower) layers chips located longitudinally and transversely in the inner layer.

Each layer is glued with waterproof resins and compressed under high pressure and temperature. As a result of this technological features of plate osb / osb acquire water resistance, elasticity and resistance to extension and construction loads. Chipboard aligned structure osb / osb manufactured by hot pressing of wood chips, mixed with a binder material. Plate osb / osb manufactured only from the particle size of 75-150 mm long, 10-25 mm in width and 0,5-0,75 mm in thickness. This ensures the homogeneity of the structure of the slab. Further, the resulting chips are dried and impregnated with a waterproof resins with the addition of a synthetic wax.

The use of wax provides high quality products. Then the chips are placed pipelined manner in two directions, creating a so-called carpet. In the outer layers of the plate chips will be oriented along the length, but in the domestic – across. After that, the carpet is pressed on the multi-tiered media at high temperatures and pressures. In conclusion, the board osb / osb cut into standard formats and grind. Technology of production boards osb / osb is constantly being improved. As binders are widely used phenol, urea-formaldehyde resin E1 class, and esters of isocyanate, which used to improve the stability properties of the slabs and improve environmental safety, the estimated emission of free formaldehyde in the environment. osb (Oriented Strand Board) – Oriented strand board ranked as number the most promising universal building material for millennia because of the whole complex of consumer benefits of this product compared to traditional wood products, provided application of new advanced technology wood modification.
