    • 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 is applied to wood to achieve a desired appearance. The customized wood is free of volatile organic compounds. 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 can 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.
    • 描述了用于定制木制品外观的紫外线C(UVC)光化学。 在一个实施方案中,将计算量的波长在100-290纳米之间的UVC辐射施加到木材上以获得期望的外观。 定制木材不含挥发性有机化合物。 应用UVC辐射的量可以基于木材的单宁含量或其他木材参数或添加的光敏剂。 UVC辐射与各种木材提取物,金属离子溶液,酸,碱和氧化剂之间的光化学相互作用可以改变木材产品的颜色或亮度。 一个示例系统包括用于以各种处理溶液以编程方式喷射木制​​品的多个工位,干燥木材,并且在工艺的一个或多个阶段用UVC辐射照射木材以与处理溶液和木材表面相互作用 时间间隔。
