Example Embodiment

[0004] The present invention will be described in detail below in conjunction with specific embodiments.

[0005] Under conventional conditions, the paulownia veneer is bleached first. The bleaching adopts the current common method of wood bleaching, and there is no special requirement. The present invention only provides a new production method for bleached paulownia veneer by imitating mahogany dyeing. specifically is:

[0006] Put the bleached 0.5mm thick paulownia veneer into a stainless steel dyeing vat, separate the veneers with a stainless steel net, pour the dyeing solution into the dyeing vat, immerse the paulownia board, and heat the dyeing solution to 90℃ under normal pressure Dyeing at a constant temperature of 90°C for 4 hours, during which the dyeing solution is circulated by rotating in the forward and reverse directions. After 4 hours, the heating is stopped, the dyeing solution is removed, the veneer is taken out after washing, and the desired paulownia imitation ...

Abstract

During dyeing, bleached single paulownia boards separated with stainless steel net are dyed in dye vat with the poured dyeing liquid comprising acid bright red, acid turquoise blue, acid bright yellow, penetrant, salt and acetic acid at 90 deg.c through circulation for 4 hr and then water washed and dried. The method is simple and can produce single paulownia board imitating red sandalwood.

Description

1. Technical field [0001] The invention relates to a production method for dyeing paulownia veneer imitation mahogany in wood production and processing. 2. Background technology [0002] Since the 1960s, Isamu Okawa, Akio Fumura, Tokuro Yokota, Yoko Kitamura, and Shigeki Yata in Japan have done in-depth research on the dyeing process and mechanism of wood. (1) The stainability of chemical composition and tissue structure of wood was studied. (2) Research on the staining properties of various dyes on wood. (3) The mechanism of dye penetration and diffusion in wood was studied. (4) The light fastness of the dyed material was studied. The application of wood staining is explored, such as standing wood staining, single-color staining, staining of laminated veneer lumber, imitation precious wood, etc. In addition, some countries also have patents on wood dyeing technology. my country began to explore wood dyeing since the late 1980s. But so far no systematic research on dye...
