Analysis of Transparent Coating Technology on the Surface Texture of Ash Veneer Based on Wavelet Component Parameters
Abstract
In order to rationally optimize the clear lacquer practice in modern furniture production application, manchurian ash rotary cut veneers was used as the substrate. The experiment selected the biorthogonal wavelet to decompose wood picture using multi-level technique, and extracted low-frequency subgraph (LL) and high-frequency subgraph (HL, LH) on wood texture after clear lacquer and conduct multi-scale spectral analysis. The quantitative comparison of the texture parameters were studied and acquired transformation rule of the wood surface texture features via after coating process through nitrocellulose varnish (glossy, matt), alkyd varnish (glossy, matt) and polyurethane varnish (glossy, matt). The results showed that : (1) Feature vector obtained by wavelet, examine the value of sub-image and standard deviation of the energy reflected in the texture characteristics, can effectively reflect the wood grain under several clear lacquer variation rule, characteristic and directional; (2) Texture enhancement significantly different, the overall effect performance is alkyd varnish (glossy) > nitrocellulose varnish (glossy) > polyurethane varnish (glossy) > Alkyd varnish (matt) > polyurethane varnish (matt) > nitrocellulose varnish (matt). Studies suggest that, clear lacquer is conducive to enhancing the substrate texture features, the effect is significant and positive for changing the visual effect.
