electrodes. The nonionic type surfactant with polyoxyethylene group is a potential corrosion inhibitor of alkaline zinc electrodes and recently the usage of it was actively researched. Nartey et al[7] identified PEG600 (polyethylene glycol 600) as a suitable organic inhibitor from eighteen organic compounds. Dobryszycki et al[8] confirmed the corrosion inhibition effectiveness of PEG400 along......
焦炭劣化抑制剂对焦炭热性能的改善研究王留成1,郑士朋1,王建设1,宋成盈1,赵建宏1(1.河南省郑州市郑州大学化学工程学院)摘 要:通过与H3BO3作对比,考察了新型焦炭劣化抑制剂A,B,ZP对焦炭热性能的影响,ZP新型焦炭劣化抑制剂改善焦炭热性能的作用比其它3种劣化抑制剂更显著.为便于工业化应用,研究了浸泡和喷洒方式对ZP作用的影响,结果表明:浸泡方式更有利于ZP作用的发挥.为进一步认识ZP作用机理,用扫描电子显微镜观察了喷洒ZP对热反应前和后焦炭形貌的影响,结果表明:喷洒ZP后焦炭表面气孔直径和深度都减小,......
