The effect of recycling process on the chemical properties and wettability of obtained fibers from MDF wastes

In this study properties of fibers recycled from MDF wastes as one of the potential important resources as raw materials for MDF production were investigated. For this purpose, two different methods including ohmic heating (for 2 and 4 min) and hydrothermal method (at 105˚c for 150 min) were utilize...
