Oriented Particle board is a new high-tech material used in Wood Frame Construction, in the manufacture of furniture, for packaging. osb boards are made by gluing large size (3-8 cm) thin chips, with upper and lower layers of the grain direction, longitudinal, and in the middle layer - cross the length of the slab. On the physical properties of osb are similar to softwood plywood, but much cheaper to manufacture due to low quality requirements for wood raw material. Because of the lower cost of the same qualities of consumer-oriented chipboard gradually replacing plywood in many traditional areas of application. Oriented strand board - a three-layer thick pressed wood board from the large-oriented chips of softwood.
A substitute for plywood and particleboard. Appearance Oriented chipboard 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 of wood chips is 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 the osb gets water resistance, elasticity and resistance to stretching and construction loads.
Particle board, oriented structure (OSB) are made by hot pressing of wood chips mixed with a binder material. Technology osb production was first applied on an industrial scale in the U.S. in early 1990. According to this production technology initially logs are sorted, then hold a special treatment and fumigate. After which the logs planed along the fibers to maximum preservation of strength of the structure of wood for wood chips. The average length of wood chips is 80 mm and the width depending on the barrel. Thus, the osb boards are made only from the particle size of 75-150 mm length, 10-25 mm in width and 0,5-0,75 mm in thickness. Smaller fraction (20-30% overall yield) and filter out or burned, or used in the manufacture of particleboard and mdf, which is used to produce non-business and small-diameter softwood and hardwood. This ensures the homogeneity of the structure of the slab.
