传统铝合金带材水洗工艺对于表面质量要求较高、表面铝粉和油脂残留较多的合金品种已经无法满足目前的市场对于品质的要求。通过在传统高压高温水洗工艺的基础上进行脱脂优化，加入一定浓度的表面活性剂混合，提高铝合金带材表面的脱脂和清洗效果，提高带材表面质量。试验采用中性的表面活性剂进行混合，对工艺在清洗能力、活性剂残留、设备腐蚀等方面进行研究。常规水洗工艺得到的带材表面灰度值通常在 5~7 级的范围，增加中性的表面活性剂后灰度值能够稳定在 2~3 级，大幅减少了带材表面的铝粉残留，有效的提高了带材表面质量。“,”The traditional water washing process for aluminum alloy strip has been unable to meet the quality requirements of the current market for the alloy varieties with higher surface quality requirements and more surface aluminum powder and grease residues. Based on the traditional high-pressure and high-temperature water washing process, the degreasing and cleaning effect of aluminum alloy strip surface were improved by adding a certain concentration of surfactant mixture, and the surface quality of the strip was improved. Neutral surfactant was used to mix in the experiment, and the cleaning ability, surfactant residue and equipment corrosion of the process were studied. The gray value of strip surface obtained by conventional water washing process is usually in the range of 5 ~ 7. After adding neutral surfactant, the gray value can be stabilized in the range of 2~3, which greatly reduces the residual aluminum powder on the strip surface and effectively improves the surface quality of strip.
