摘要
本文注意到青铜病的粉状锈中有活性和非活性成分的区分。活性粉状锈是影响青铜器稳定的关键,采用BTA-H2O2试液多次局部处理,可以使青钢器锈层缝隙内的活性粉状锈变成蓝色絮状物排泄出来,直至局部区域完全除去粉状锈。然后对器物进行缓蚀处理,使之稳定。试验表明采用BTA-Na2MoO4-NaHCO3复合配方比单独用BTA处理的效果更好。
The differences between active component and inactive component in the powdery rusts of"bronze disease" are recognized in this paper.The key to the influence on stability of bronze lies in the active powery rust. The experiment indicated,useing BTA-H2 O2 coated on the corroded surface of the bronze,the active powery rust can be changed to blue wadding material which will out from the cracks on the rusts until nothing get out from there.Then carry on inhiliting treatment and make it stable.The experiment show that the effect of BTA-Na2 MoOi-NaHCOs is better than the effect of single BTA.
