摘要 目的研究二氧化氯、过氧化氢和过氧乙酸对金属的腐蚀性。方法选用4种二氧化氯、3种过氧化氢和3种过氧乙酸产品,研究其对碳钢、铝、铜、不锈钢和锌片5种金属的腐蚀性,计算腐蚀速率。结果300 mg/L的二氧化氯液体制剂对碳钢片、铜片、铝片和锌片腐蚀性都达到重度腐蚀;500 mg/L条件下二氧化氯液体对不锈钢片仍基本无腐蚀。3%过氧化氢液体对碳钢片和不锈钢片基本无腐蚀,对铜片和铝片轻度腐蚀,对锌片重度腐蚀。1.0 g/L过氧乙酸液体制剂对碳钢片、铜片和锌片重度腐蚀,对铝片中度腐蚀,对不锈钢片基本无腐蚀。结论3类过氧化物类消毒剂除对不锈钢基本无腐蚀之外,对其他4种金属均存在不同程度腐蚀性,其中过氧化氢腐蚀性较低,二氧化氯次之,过氧乙酸最高。 Objective To study the corrosion of metals by chlorine dioxide,hydrogen peroxide,and peracetic acid.Methods Four kinds of chlorine dioxide,three kinds of hydrogen peroxide and three kinds of peracetic acid products were selected to study their corrosiveness to five kinds of metals of carbon steel,aluminum,copper,stainless steel and zinc sheet,and the corrosion rate was calculated.Results The liquid formulation of 300 mg/L chlorine dioxide exhibited severe corrosion on carbon steel sheets,copper sheets,aluminum sheets,and zinc sheets;Under the condition of 500 mg/L,chlorine dioxide solution still had little corrosion on stainless steel sheets.3%hydrogen peroxide solution had little corrosion on carbon steel and stainless steel sheets,mild corrosion on copper and aluminum sheets,and severe corrosion on zinc sheets.1.0 g/L peroxyacetic acid liquid preparation caused severe corrosion to carbon steel sheets,copper sheets,and zinc sheets,moderate corrosion to aluminum sheets,and minimal corrosion to stainless steel sheets.Conclusion Except for stainless steel,three types of peroxide disinfectants have corrosiveness to other four metals,hydrogen peroxide has lower corrosiveness,followed by chlorine dioxide,and peroxyacetic acid has the severest corrosivenes.
