Case: Coastal Bronze Sculpture Sealing System
案例：海岛气候青铜雕塑封护体系
标签：海洋气候, 封护体系, 盐雾, 案例
某海岛广场青铜像（距海 80 m，C5-M 等级）建立五层封护体系：①热水洗盐（60 ℃，200 L/min 循环 2 h）②BTA 1% 乙醇液浸涂 24 h ③硅烷纳米封护两道 ④氟碳面漆 35 μm×2 ⑤年检 + 24 个月复涂氟碳。运行 6 年盐雾点蚀为零，对比邻近未封护铜灯柱已现层状剥落。年度维护成本仅约为雕像造价 0.3%，核心投入在首年体系化施工。
A seaside bronze monument 80 m from the surf (C5-M) runs a five-layer system: hot-water desalination (60 °C, 2 h loop), 24 h immersion in 1% BTA ethanol, two coats of nanosilane, fluorocarbon topcoat 35 μm ×2, and annual inspection with fluorocarbon renewal every 24 months. Six years on: zero salt-pitting, while an unprotected copper lamp post nearby shows laminar exfoliation. Annual cost is ~0.3% of the sculpture value—the investment is in the first-year systematic application.
