In this paper, we used water-based acrylic varnish to coat poplar and pinus sylvestris veneer, discussed the inhibition effects of veneer light induced discoloration with two coating ways which were paint coating and film covering. The result showed that, after paint coating or film covering, the lightness aberration of veneer ΔL* and chromatism ΔE*ab were significantly reduced. The inhibition rate of veneer light induced discoloration with film covering was 7.88% higher than that with paint coating, reaching 30.41%.It mainly because of the small change of color index b* of film covered veneer, the water-based varnish film to a certain extent could inhibit the wood photochemical consequences by ray radiation. It’s feasible to study light induced discoloration of coated veneer by the method of film covering.
This paper used pattern design, colour design and mold design comprehensively, using compression molding and simulated carving technology, studying a way to realize the pattern simulation of woodiness restructuring decoration. The result showed that it’s feasible to simulate pattern of new woodiness restructuring decoration, and the adornment effect was good. The line of the simulated pattern needed to be smooth. it’s better for the color in per unit area to be less. During the compression molding of board, the key point of decorative pattern simulation was the mould design. As adornment material instead of structural one, the technological parameters such as impregnation, pressure of hot pressing, time of hot pressing process during the process of preparation had a small effect on the adornment of board.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
