目的 研究PRO-pHx 酸活剂对酸洗过程及酸洗质量的影响,达到节酸、减排、降低成本的目标.方法 通过添加PRO-pHx 酸活剂,对比分析酸洗溶液更换周期,以及不同的使用酸周期的成本. 结果PRO-pHx酸活剂体积分数在1%以下,即可长期保持钢铁零件酸洗液的活性以及零件的表面酸洗质量和电镀层质量,同时减少酸液废弃量. 其中,1200 L的硫酸酸洗槽加入体积分数为1%的PRO-pHx酸活剂,到第30个使用周期成本节约了33 . 6%,且随周期延长酸洗成本会进一步降低. 结论 PRO-pHx 酸活剂添加到酸洗溶液中,在保证钢铁零件表面酸洗质量和电镀层质量的前提下,实现了节酸、减排、降低成本.
Objective In order to study the effect of PRO-pHx acid active agent on the pickling process and pickling quality, and to reach the goals of saving acid, reducing emission and decreasing cost. Methods The PRO-pHx live agent was added, and the replacement cycle of acid pickling solutions was comparatively analyzed, as well as the costs of different acid usage cycles. Results A concentration of 1% or less of PRO-pHx acid activating agent could maintain the activity of galvanized parts pickling so-lution for a long time, as well as the surface pickling quality of steel parts and electroplating quality, meanwhile, the amount of waste acid was reduced. Adding 1% PRO-pHx acid active agent in a 1200 L sulfuric acid pickling tank could reduce the cost by 33. 6% at the 30th cycle, and the costs would be further reduced with the extension of the pickling cycle. Conclusion Adding PRO-pHx acid active agent in acid pickling solution realized acid conservation, emissions reduction and cost reduction on the prem-ise of the good quality of surface pickling of steel parts and electroplating coating.
