Ultraviolet-C photochemistry for customizing an appearance of a wood product |
摘要 |
Ultraviolet-C (UVC) photochemistry for customizing an appearance of a wood product is described. In an implementation, a calculated amount of UVC radiation at a wavelength between 100-290 nanometers, for example, is applied to wood to achieve a desired appearance. The customized wood is free of the volatile organic compounds (VOCs) of stains, varnishes, and paints. The amount of UVC radiation to apply can be based on the tannin content of the wood or on other wood parameters or added photoactive agents. Photochemical interaction between the UVC radiation and various wood extracts, metal ion solutions, acids, bases, and oxidizers is also used to modify the color or lightness of a wood product. An example system includes multiple stations for programmatically spraying a wood product with various processing solutions, drying the wood, and irradiating the wood at one or more stages of the process with UVC radiation to interact with both the processing solutions and the wood surface, at programmed time intervals. |

1. A system, comprising:
an array of ultraviolet-C (UVC) radiation sources; and a conveyor for transporting a wood product under the array of UVC sources to interact a UVC radiation with a surface of the wood product for modifying an appearance, color, texture, lightness, contrast, reflectivity, grain feature, or knot feature of the wood product. |
