摘要

介绍。由于腐蚀对农林机械的损害,维护其性能的成本正在增加。使用水溶性抑制剂可以减缓或停止这一破坏过程。然而,许多抑制剂有缺点,例如,易燃性或毒性。本研究旨在研究硼酸酯和三乙醇胺水溶液的防腐效果,并对其在农林机械长期储存中的防腐保护提出建议。材料与方法。将硼酸酯和三乙醇胺溶于蒸馏水和工业水中,在室温下制备了防护组合物。水溶液中水溶性抑制剂的浓度为5-50 g/l(0.5-5质量%)。采用线性极化电阻法对其保护效能进行了评价。使用Solartron (UK)测量配合物进行电化学研究。根据GOST 9.054-75在g-4湿度仪中对钢板进行了加速腐蚀试验。通过残膜保护效果评价了水溶性缓蚀剂的后效。结果。研究了硼酸酯和三乙醇胺在水溶液中的浓度对其防护性能的影响。硼酸和三乙醇胺减缓了阳极反应。对研究结果的分析表明,随着工艺水中水溶性缓蚀剂浓度的增加,钢电极的腐蚀速率降低。当硼酸和三乙醇胺的浓度在10-50 g/l范围内时,这种降低最为明显,当硼酸和三乙醇胺的浓度增加到50 g/l时,其保护效率变化幅度为6 - 14%。在对钢板进行腐蚀试验时,得到了该组合物中缓蚀剂的最佳浓度为10 g/l,当该水溶性缓蚀剂浓度为10 g/l时,溶液的防护效率可达70%以上。在样品有沉淀的情况下,溶液的保护效率下降到20 - 25%。在一年中,在一个封闭的不加热的房间里对钢样品进行测试时,没有腐蚀的痕迹。结论。研究表明,硼酸和三乙醇胺是一种水溶性阳极腐蚀缓蚀剂。随着工艺水中水溶性缓蚀剂浓度的增加,钢电极的腐蚀速率降低。保护液中硼酸与三乙醇胺酯的最佳浓度为10 g/l。在钢板腐蚀试验中,水溶性缓蚀剂溶液的屏蔽效能可达70%以上。在直接暴露于大气降水的条件下,溶液对样品的防护效率下降到20 - 25%。当在一个封闭的不加热的房间里对钢样品进行测试时,一年中没有腐蚀的痕迹。因此,硼酸和三乙醇胺的酯在封闭的房间中有效地防止大气腐蚀。建议用于汽车在露天平台上短期存放时的防腐保护。明确了水溶性缓蚀剂在农林机械长期保存中的应用领域;提供了清洁汽车污染和保护其表面免受腐蚀的组合阶段。本文对农业机械防腐领域的专家有一定的参考价值。

Protective Efficiency of Water-Soluble Corrosion Inhibitors
Introduction. As a result of damage to agricultural and forestry machines from corrosion, the costs of maintaining their performance are increasing. The use of water-soluble inhibitors can slow or halt the destructive process. However, many of the inhibitors have disadvantages, for example, flammability or toxicity. The purpose of this work is to study the protective effectiveness of aqueous solutions of boric acid ester and triethanolamine and to develop recommendations for their use for anticorrosive protection of agricultural and forestry machinery in long-term storage. Materials and Methods. Protective compositions were prepared by dissolving boric acid ester and triethanolamine in distilled and industrial water at room temperature. Aqueous solutions with a concentration of water-soluble inhibitors of 5–50 g/l (0.5–5 mass %) were used for research. The linear polarization resistance method was used to assess their protective efficiency. Solartron (UK) measuring complex was used for electrochemical studies. Accelerated corrosion tests were carried out on steel plates according to GOST 9.054-75 in the g-4 humidistat. The aftereffect of water-soluble corrosion inhibitors was evaluated by the residual film protective efficiency. Results. The influence of the concentration of the ester of boric acid and triethanolamine in aqueous solutions for their protective properties is studied. It was found that boric acid and triethanolamine slow the anode reaction. The analysis of the research results has showed that the corrosion rate of the steel electrode decreases with increasing the concentration of water-soluble inhibitor in process water. This decrease is the most noticeable when the concentration in the range of 10–50 g/l with an increase in the concentration in the solution of boric acid and triethanolamine to 50 g/l, their protective efficiency varies by 6–14 %. The optimal concentration of the inhibitor in the composition is obtained, which is 10 g/l during corrosion tests of steel plates, the protective efficiency of the solution with a concentration of 10 g/l of the water-soluble inhibitor was more than 70 %.

When tested in a closed unheated room on steel samples during the year there were no traces of corrosion. Conclusions. The study demonstrates that boric acid and triethanolamine is a watersoluble inhibitor of anodic corrosion. When the concentration of water-soluble inhibitor in process water increases, the corrosion rate of the steel electrode decreases. Optimum concentration of ester of boric acid and triethanolamine in the protective solution should be 10 g/l.
