Factors influencing mechanical properties of OSB

Abstract

With more and more buildings built around the world, OSB is an important building material. Learning about its properties can help people make use of the OSB panel effectivity. In this paper, the author will examine the relationship between OSB and these factors by looking at published data. Secondly, the author will introduce the production method of OSB, the structure of OSB, the application of OSB, and the basic properties of OSB. This article describes which factors affect the properties of OSB. It also helps to learn about how the properties of OSB change in a particular case and how to manufacture OSB the most efficiently. People have tested OSB at different densities under the manufacturing process according to the standard of SN EN 300 in order to reduce the experimental error. The results show that the mechanical properties of OSB are better with higher density. Resin is another factor to affect the mechanical properties of OSB. In the experiments, different types and amounts of resin to manufacture OSB are tested. Then OSB mechanical properties are tested for the variations in manufacturing listed above. The results show that the more resin used to a certain degree, the better the OSB mechanical properties. The urea-formaldehyde and the Phenol - formaldehyde resins are two resins normally used in OSB. The result shows that using the Phenol - formaldehyde for OSB displays better mechanical properties than urea-formaldehyde. The species of raw material is another factor affecting the mechanical properties of wood. In the experiment, the mechanical properties of OSB made of pine, hardwood mixture, and aspen were tested. However, there is some error caused by different manufacturing methods.
