Shavings 1. From the tree to the OSB board OSB Croson is fine structure, fiber texture straight through fresh pine peeled, cut along the direction of the grain with a certain geometry (usually length 40-120mm, width 5 -20mm, between thick 0.40-0.60mm), applied after drying synthetic resin glue and water repellent, simulate natural wood fiber orientation, the orientation of pavement into slabs after a high temperature and then made more pressing man-made structures layer sheet. Fresh pine subject to careful selection, which requires selection of the core timber felled within four weeks, the surface requires no more than a week of timber felling. 2. The three layers - ensure high mechanical properties and dimensional stability Croson OSB board consists of three layers: the upper and lower skin layer and a core layer. Its core is symmetrical with the upper and lower layers, the surface shavings were arranged longitudinally, transversely aligned core particle, this overlap vertically staggered so that the finished structure has a very high mechanical properties and dimensional stability, can in the long bearing load Under the circumstances, it remains deformed. 3. The formaldehyde-free adhesive - Ensure the European E1 formaldehyde emission standards. Croson OSB plate core is used isocyanate glue (PMDI glue), the surface used is melamine urea formaldehyde resin used in the release. The continuous suppression of the production line - to ensure product quality surface has two world-class facilities, continuous suppression of the production line, so that the thickness variation between the products is almost zero; in general flattening can only obtain a single high-quality surfaces, and continuous suppression Production line can get two high quality surfaces; synthetic resin glue and water repellent surface applications, to ensure that products with a high moisture resistance, can be used in wet environments. Hot - ensure Croson OSB plate by hot dense structure, it is possible to accelerate the adhesive curing speed, the slab in contact with compacted debris, the slab reaches a predetermined thickness
