Effects of Peripheral Planing on Surface Characteristics and Adhesion of a Waterborne Acrylic Coating to Black Spruce Wood
Source abstract
Abstract
Abstract Peripheral planing of black spruce (Picea mariana) wood was optimized for rake angle and feed speed. Both cutting parameters affected surface characteristics at the microscopic and macroscopic level. In turn, the interaction between rake angle and feed speed had a significant impact on surface roughness, disperse component of surface energy, and total surface energy, as well as on initial pull-off adhesion strength of a waterborne coating. Loss in adhesion during the accelerated aging treatment was significantly lower for samples machined with a rake angle of 10°. This rake angle combined with a wavelength (feed per knife) of 1.3 mm yielded coated surfaces with high initial pull-off strength. Therefore, this wavelength could be used to increase production rates without significantly affecting surface quality. In addition, no torn grain was observed for surfaces prepared with a rake angle of 10° regardless of feed speed.
