Community Cross-testing Program for Sealer Weatherability
封护剂耐候数据的社区互测计划

单一工作室难有 3–5 年自然暴晒数据，社区互测可补此短板。做法：统一规格试片（100×100 mm 同批 1 mm 紫铜），按统一流程封护——除油、BTA、两道封护并记录膜厚——随后每名成员把试片暴露在自己所在气候区（海滨/城市/工业/干燥内陆）的南向 45° 晒架上，每半年上传照片、光泽度与划格附着力数据到共享表格。年度汇总按气候区分别排名，能得出"某氟碳在滨海 18 个月粉化、在内陆干燥区 4 年完好"这类地域性结论，比实验室加速试验更贴近真实工程判断。
No single studio owns 3–5 year outdoor data; community cross-testing fills the gap. Use standardized coupons (100×100 mm, one batch of 1 mm copper), sealed to one protocol — degrease, BTA, two coats with recorded DFT — then each member exposes coupons on a south-facing 45° rack in their own climate (coastal/urban/industrial/dry inland), uploading photos, gloss and cross-hatch adhesion every six months to a shared sheet. Annual summaries rank products per climate zone, yielding regional truths such as "fluorocarbon A chalked in 18 months on the coast but lasted 4 years inland" — closer to real engineering judgment than any accelerated lab test.
