ABSTRACT

Nineteen brands of latex-free, powder-free, disposable nitrile glove were investigated for use when dry handling art. Results from a rub test, a modified Oddy test, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), and ion chromatography (IC) were combined to identify gloves that caused the least damage to artificially aged metal coupons. The rub test involved repeated wiping of lead (Pb), copper (Cu), and silver (Ag) coupons with donned gloves then visually assessing the result to look for evidence of deposited residues. Ten brands deposited residues. The modified Oddy test studied the impact of glove handling on evidence of coupon corrosion. Twelve glove brands instigated moderate to severe corrosion of the coupons during artificial aging. SEM-EDS data showed that deposited residues led to pitting and corrosion of coupon surfaces with the presence of chlorine and oxygen dominating corrosion sites. Larger amounts of chloride ions (Cl^–) in gloves were affiliated generally with greater corrosion. Ansell Bioclean™ Biotac white cleanroom and Showa® 7500PF blue economy grade gloves deposited no visible residues, induced minimal corrosion, and showed lower anion contents relative to other gloves, making them the best brands tested here for dry handling art.

摘要

对 19 个品牌的无乳胶、无粉、一次性丁腈手套进行了调查，以用于干式处理艺术。将摩擦测试、改进的 Oddy 测试、扫描电子显微镜-能量色散光谱 (SEM-EDS) 和离子色谱法 (IC) 的结果结合起来，以确定对人工老化金属试样造成最小损坏的手套。摩擦测试包括戴上手套反复擦拭铅 (Pb)、铜 (Cu) 和银 (Ag) 试样，然后目视评估结果以寻找沉积残留物的证据。十个品牌存残。改进的 Oddy 测试研究了手套处理对试样腐蚀证据的影响。12 个手套品牌在人工老化过程中对试样进行了中度至重度腐蚀。SEM-EDS 数据显示，沉积的残留物导致试样表面出现点蚀和腐蚀，其中氯和氧占主导地位。大量的氯离子（Cl^– ) 在手套中通常与更大的腐蚀有关。Ansell Bioclean™ Biotac 白色无尘室和 Showa® 7500PF 蓝色经济级手套没有沉积可见残留物，引起的腐蚀最小，并且与其他手套相比显示出较低的阴离子含量，使其成为这里测试干处理艺术的最佳品牌。
