有机缓蚀剂最早的专利是植物提取物,以后全部被合成产品所取代。然而,近年来的研究表明,某些植物提取液或其复配物,不但对金属在酸性、碱性或中性介质中的腐蚀有明显的抑制作用,而且具有价格低廉,低毒甚至无毒,不污染环境等优点。因此,用植物提取液作为缓蚀剂的研究,再度引人注目。本文研究了黄柏等植物的提取液对10％盐酸中碳钢腐蚀的缓蚀效果。实验方法 1.将黄柏等植物分别用A、B、C、D四种溶剂提取,制得2.5％(W/V)的提取
Organic corrosion inhibitor earliest patent is a plant extract, after all were replaced by synthetic products. However, recent studies have shown that certain plant extracts or their complexes not only have a significant inhibitory effect on the corrosion of metals in acidic, alkaline or neutral media, but also have low cost, low toxicity and even no toxicity , Does not pollute the environment and other advantages. Therefore, the use of plant extracts as a corrosion inhibitor, again attracts attention. In this paper, cork and other plant extracts of 10% hydrochloric acid corrosion of medium carbon steel corrosion inhibition. Experimental methods 1. Cork and other plants were A, B, C, D four kinds of solvent extraction, obtained 2.5% (W / V) of the extraction
