ABSTRACT

Whilst research has been published on the impact of pollution on glass, there is no consensus on the risk from formaldehyde. A controlled relative humidity (RH) showcase used with visually weeping glass was studied. At under 42% RH, the presence of formaldehyde and formic acid continue to produce sodium formate salts on the glass surface. Estimates of the glass deterioration rate have been made. The likely occurrence of a Canizzaro type reaction was elucidated by the formation of methanol in both laboratory and field measurements.

受控相对湿度条件下渗漏玻璃劣化研究

摘要

虽然已经发表了关于污染对玻璃的影响的研究，但对于甲醛的风险还没有达成共识。研究了与目视流泪玻璃一起使用的受控相对湿度 (RH) 展示柜。在 42% RH 以下，甲醛和甲酸的存在继续在玻璃表面产生甲酸钠盐。已经进行了玻璃劣化率的估计。通过实验室和现场测量中甲醇的形成阐明了可能发生的 Canizzaro 型反应。
