AI Technical Summary

Technical Problem

Existing ceramic filter plate cleaning agents are mostly strong acid systems, which can easily corrode equipment and have problems such as high environmental pressure, high corrosivity, and a positive correlation between descaling ability and corrosivity.

Method used

Hydroxyethylidene diphosphonic acid is used as a chelating agent to form a mild organic acid system. Combined with oleic acid imidazoline quaternary ammonium salt and corrosion inhibitors, a dense protective film is formed to prevent equipment corrosion. The cleaning agent is made efficient and environmentally friendly through a gradient step-by-step premixing process and low-humidity closed production.

Benefits of technology

It achieves efficient cleaning of deep dirt in the micropores of ceramic filter plates, reduces equipment corrosion rate, meets environmental protection requirements, is suitable for large-scale industrial production, and reduces energy consumption and costs.

Abstract

本发明公开了一种高效环保固体陶瓷过滤板清洗剂，以重量百分比计包括有机酸20‑30%，螯合剂4‑10%，缓蚀剂4‑10%，阳离子表面活性剂1‑3%，无水硫酸钠补充至100%。本发明采用氨基磺酸与柠檬酸形成温和有机酸复合体系，替代传统强无机酸体系，降低体系的酸性，从源头降低腐蚀性，延长设备的使用寿命。彻底打破了现有技术“除垢能力越强、腐蚀性越高”的技术偏见，实现了高效除垢与零腐蚀防护的兼顾。通过梯度分步预混工艺，解决了密度差异导致的分层、分散不均问题；全流程低湿度密闭生产，避免有机酸吸潮结块。不含有氢氟酸、含磷助剂等高污染、高风险成分，符合国家环保与安全要求，符合绿色工业发展趋势。
