摘要 采用失重法,研究在通大气的接近中性的50℃除盐水中,通过调节pH值、加缓蚀剂防止碳钢在除盐水中腐蚀的情况,主要研究调节pH值和加缓蚀剂咪唑啉防止碳钢腐蚀情况的差异。试验结果表明,通过调节pH值和加入咪唑啉均可防止碳钢的腐蚀,但调节pH仅在短期有效,而加入合适浓度的咪唑啉可以保持碳钢较长时间不腐蚀。 The effect of adjusting pH and adding inhibitor to prevent carbon steel from corrosion in the de-salting water, which is close to neutral, open to atmosphere at 50?C, is studied through weight loss method, and the difference of anti-corrosion effect between the two methods is mainly studied. The test results show that the corrosion of carbon steel can be prevented by adjusting pH and adding imidazoline, and its corrosion can be prevented by adding imidazoline with a proper concentration for a long time, only can be prevented by adjusting pH for a short period of time.
