Combining Electro-colored Copper with Wood
电解着色铜板与木材的组合工艺
标签：跨材料, 铜木结合, 灯具, 膨胀缝, 结构胶
灯具与家具厂将电解着色铜板（0.5–1 mm）与胡桃木、橡木拼接：铜板着色至蓝黑或紫褐后先喷 2K 聚氨酯封护，边缘折边 3–5 mm 埋入木槽，以环氧或 PU 结构胶粘接，避免铆钉破坏膜层。关键控制木铜膨胀系数差——阔叶材含水率须 8±2%，并预留 0.2 mm 伸缩缝；胶合前对膜面等离子处理或涂底涂剂提升附着力。组合件按家具类标准做 24 h 冷热循环验证，釉色封护层无龟裂为合格。
Lighting and furniture shops join electro-colored copper sheet (0.5–1 mm) with walnut or oak: color to blue-black or purple-brown, seal with 2K polyurethane, fold edges 3–5 mm into a wood rebate and bond with epoxy or PU structural adhesive—no rivets to breach the film. Manage the wood-metal expansion mismatch: hardwood at 8±2% moisture, 0.2 mm expansion gaps, plasma or primer treatment on the film before bonding. Finished assemblies pass 24 h hot-cold cycling with no sealant cracking.
