摘 要: 采用紅外光譜、 X射線衍射和XPS等分析方法, 分析了鋁箔軋制過程中所形成油泥的物質(zhì)組成及結(jié)構。結(jié)果表明, 油泥主要由約40%的鋁屑、 60%的軋制油及其氧化物組成的粘稠狀黑色混合物; 鋁屑表面脂肪酸鋁鹽在促使鋁屑聚集成油泥過程中起著重要作用,軋制油氧化也是生成油泥的一個不可忽視的因素; 油泥的生成與軋制油的性能密切相關, 軋制油的潤滑性能差、 承載能力低、 酸值高、 抗氧化穩(wěn)定性能低均可促使油泥的生成。提出了減少或抑制油泥生成的對策。

Abstract:The constitutes and structures of oil sludge produced in the process of rolling aluminum foil were analyzed by means of infrared spectrum analysis and X-ray diffraction analysis and XPS analysis. The results showed that the oil sludge is a kind of viscous black mixture of about 40% aluminum powder, 60% rolling lubricant and its oxidate, and the aluminum soap in the surface of aluminum powder plays an important role in accelerating aggregation of aluminum powder, and the oxidation of rolling lubricant is not a negligent factor of producing oil sludge. The oil sludge formation is correlative with the lubricant character, the poor behaviors of the lubricant, such as low carrying capacity and/or high acid value and/or low inoxidizable stabilization, can result in formation of oil sludge, the countermeasure in reducing or restraining oil sludge was introduced accordingly.
