近年来,以天然物质为原料,制取高效、无毒、使用范围较宽、环境影响较小的优质实用缓蚀剂的研究工作,有了新的进展,开辟了新的领域。许多价廉无毒且具有良好缓蚀性能的天然物质或工业副产物以及釜残等,引起了一些研究者的兴趣与关注,但报道的成功实例并不多。我们用固液萃取方法,以水生植物的叶、茎、花、根作基础原料,进行抽提复配,制成了一种高效、无毒、适用范围较宽的酸洗缓蚀剂—LK型缓蚀剂。这种缓蚀剂既适用于氧 In recent years, with natural materials as raw materials, the preparation of high quality, non-toxic, wide range of use, environmental impact of small and high-quality practical corrosion inhibitor research has made new progress and opened up new areas. Many natural materials or industrial by-products with low cost, non-toxic properties and good corrosion inhibition properties, as well as kerogen aroused the interest and attention of some researchers. However, there are not many successful examples reported. We use solid-liquid extraction method to aquatic plant leaves, stems, flowers, roots as the basic raw materials, extraction and compounding, made of a highly efficient, non-toxic, wide range of applications pickling inhibitor - LK Corrosion inhibitor. This corrosion inhibitor applies to both oxygen
