Coloring Copper-Wood Composite Furniture
铜木结合家具的着色协调

铜包边桌面、铜腿木板的着色顺序是"先木后铜"：木皮先染底色并封两道底漆，再对铜件着色，避免硫化液渗入木纹留下灰黑晕。铜件用 0.5–0.8 vol% 硫化钾棉擦 2–3 遍，接缝处以美纹纸 + 可剥橡胶遮蔽剂双重防护，遮蔽边缩进 0.5 mm 让铜色"咬"住木线。铜侧烘烤或热风须控制在 60 °C 以下，防止木材脱胶与漆膜起泡；完成后铜面蜡封、木面同批清漆罩面，光泽统一为哑光 20°。
On copper-edged tables the order is "wood first, copper second": dye and seal the veneer with two primer coats before coloring the copper, so sulfide never bleeds a grey halo into the grain. Brush 0.5–0.8 vol% potassium sulfide onto the copper in 2–3 wipes, double-mask joints with crepe tape plus peelable rubber, and pull the mask back 0.5 mm so color bites into the wood line. Keep any heat below 60 °C to protect glue and lacquer; finish with wax on copper and matching matte (20°) clear on wood.
