Properties of Osb Panels with Veneer Inclusion

This work aimed to evaluate the effect of veneer inclusion with different wood species, and also different levels of pressing pressure applied in the moment of the veneer inclusion over physicalmechanical properties of already consolidated OSB (Oriented Strand Board) panels. Treatments were arranged in factorial scheme 4 x 2 (four wood types for veneer inclusion – Pinus oocarpa, Eucalyptus urop...

Applicability of Strand Substitution in the Core of Osb

Strand substitution was evaluated for the core of OSB with chips produced by grinding of recycled particleboards and wood waste. All the boards manufactured under laboratory conditions having a share of small chips in the core had high mechanical parameters, thus meeting the requirements of the standard for OSB/3. No significant effect was found of the applied modification of the core on bendin...

بررسی امکان ساخت تخته تراشه جهت‌دار (OSB) از چوب ممرز

DOR:98.1000/1735-0913.1398.34.140.66.1.9.1586 در این تحقیق امکان ساخت تخته تراشه جهت‌دار سه لایه از چوب گونه ممرز (Carpinus betulus L.) مورد ارزیابی قرار گرفت. برای این منظور تخته‌های آزمایشگاهی به ضخامت 12 میلیمتر از چوب ممرز، در حالی که جهت تراشه‌های لایه سطحی در جهت طول تخته و جهت تراشه‌های لایه میانی عمود بر لایه سطحی بود، با استفاده از دو سطح زمان پرس 6 و 8 دقیقه و سه سط...

An optical technique for determination of layer thickness swell of MDF and OSB

e have been studying the phenomenon of thickness swell in woodbased composites as part of our overall research program to address composite product manufacture and performance (Xu and Winistorfer 1995a, 1995b; Wang and Winistorfer 2000a, 2001). We purport that one of the key variables in understanding the thickness swell phenomenon is recognition of the density profile through the panel thickne...
