冰蓄冷空调系统中乙二醇的缓蚀剂研究
Journal of University of Shanghai for Science and Technology(2014)
Abstract
采用静态失重法研究了钼酸钠和硼砂的复配缓蚀剂对冰蓄冷系统中所用的乙二醇溶液的缓蚀作用,结果表明,单一的钼酸钠或硼砂缓蚀剂虽有效果,但所需剂量均偏大,质量浓度在600 mg/L时缓蚀率分别为61.6%和74.8%.复配后两者具有协同作用,可减少缓蚀剂用量.600mg/L的复配缓蚀剂的缓蚀率可达到80%以上,投加量仅占溶液总质量的0.05%,并且得到本实验钼酸钠和硼砂质量浓度的最佳配比为1∶4,缓蚀率达到了90.2%.
