Enamel Panels Combined with Solid Wood
珐琅板与实木家具的组合工艺

桌面与柜门用 1–1.5 mm 珐琅铜板嵌入实木框：铜板四周折边或包黄铜边条，以"浮挂式"滑槽安装，四周各预留 1 mm 伸缩量。核心是木与铜吸湿膨胀差——实木含水率控制在 8±2%，跨度超过 600 mm 时中间加隐形压条防止釉面受弯开裂；胶粘方案仅适用小于 300 cm² 的小面积，且用低模量硅烷胶。组合件出厂前做 -10℃/40℃ 五次循环试验，釉面无裂纹为合格。北欧家具品牌近年以此工艺量产装饰柜门。
Tabletops and cabinet doors set 1–1.5 mm enamel-copper panels into solid-wood frames: folded edges or brass trims, "floating" groove mounting with 1 mm clearance all round. The core issue is moisture-expansion mismatch—hardwood held at 8±2% MC; spans over 600 mm get a concealed mid-brace to keep bending from cracking the glaze. Adhesive fixing suits only areas under 300 cm² with low-modulus silane sealant. Assemblies pass five -10℃/40℃ cycles crack-free before shipment—now a Nordic furniture production idiom.
