某地铁艺术墙(3.5 m × 12 m,384 块 200×200 mm 掐丝铜板)全面采用无铅釉,通过耐磨测试(1000 次循环无露底)满足高频使用区要求。因无铅釉烧成窗口窄(±10℃),建立每炉试片制度:每窑随炉放 3 片色标,色差 ΔE>1.5 即调整炉温。项目工期 4 个月,成品率从初期 82% 提升至 96%。

A metro art wall (3.5 m × 12 m, 384 cloisonné copper panels at 200×200 mm) used lead-free enamel throughout, passing abrasion testing (1000 cycles, no bare metal) for high-touch zones. With the narrow ±10℃ firing window, a per-kiln coupon system was set: three color coupons per firing, adjusting temperature when ΔE>1.5. Over the 4-month project, yield rose from 82% to 96%. ---
