Abstract In order to improve hydrophobic characteristics which will affect the service performance of fast-growing poplar due to growing bacteria in the humid environment. In this study, a simple method was proposed to treat poplar via the high voltage electric field (HVEF) with copper as the electrode plate. Scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD) and contact angle tester were adopted to evaluate the surface morphology, surface group of poplar, crystallinity and wettability under HVEF. It was found by SEM that a large number of copper particles were uniformly attached to More >

Abstract In this study, the effects of three different particle sizes of wood wastes (A = –8 + 12 mesh; B = –12 + 20 mesh; C = –20 + 30 mesh) and factory shavings (D) on the properties of particleboard were investigated. According to the test results, three-layer particleboard was designed. Particleboard face layers made with mixture of A, B, and C. The core layer made with D. The ratio of core layer to face layers is 50:50. Three-layer particleboard were fabricated with 12% urea-formaldehyde (UF) resins and three different high voltage electrostatic field intensities… More >
