标签：配方,BTA,苯并三氮唑,缓蚀膜,低毒
将 BTA 溶于乙醇或温水配成 1–3% 溶液，浸涂或喷涂于清洁铜面，干燥后形成分子缓蚀膜，显著抑制铜绿生成。BTA 低毒但仍需通风，避免吸入粉尘与溶液接触皮肤。
Dissolve BTA in ethanol or warm water to 1–3%, then dip or spray onto clean copper; it dries to a molecular film that strongly suppresses patina growth. BTA is low-toxic but still needs ventilation—avoid dust inhalation and skin contact. ---
