Comparison study of thickness swell performance of commercial oriented strandboard flooring products

چکیده
Oriented strandboard (OSB) is generally manufactured as a three-layer mat structure for enhanced bending performance. Virtually all OSB is manufactured to achieve performance standards, however, different manufacturers have different process techniques that result in different performance. Comparisons of the performance of commercial OSB in the current market have not been exclusively conducted. A goal of this study was to investigate the effects of manufacturing or product parameters on the dimensional stability of commercial OSB panels. The effects of species and resin type in the panels were examined for flooringproducts, i.e., 23/32-inch-thickOSBtongueandgroove (T&G) panels. A similar study has been done on sheathing products, i.e., 7/16-inch-thick OSB panels (Wang et al. 2003). Understanding the impact of the product’s parameters on performance is important for optimizing structure in the development of new products and improving the manufacturing process. The multiple-layer structure of OSB has a significant influence on thickness swell (TS). TS is recognized as an important

Physical and mechanical properties and fire, decay, and termite resistance of treated oriented strandboard
This study evaluated the effects of a number of chemicals on the physical and mechanical properties and fire, decay, andtermite resistance of oriented strandboard (OSB) panels. Disodium octaborate tetrahydrate (DOT), boric acid (BA), melamine phosphate (MP), and a BA/DOT mixture were sprayed onto the furnish at varying concentrations. Thepanels were tested for thickness swell, water absorption,...

The objective of this study was to investigate the effects of hot water extraction process on the dimensional stability of oriented strand composites. Aspen wood strands were extracted using various severity factor levels. Phenol formaldehyde and polymethylene diphenyl diisocyanate resins were used for production of the oriented strandboard panels. Six panel groups were produced from the extrac...

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...

Extensive research has been carried out on the thickness swell (TS) behavior of different types of wood composite panels. Of particular interest, studies investigating layer TS behavior have been carried out by Wang and Winistorfer (2003, 2001, 2000), and Xu and Winistorfer (1995a and 1995b). Results from these studies clearly indicate that the majority of TS in wood composite panels, such as m...
