PASP阻垢缓蚀剂缓蚀机理研究 总被引:2,自引:2,他引:2
绿色化是21世纪水处理药剂的发展方向,以聚天冬氨酸(PASP)代表的绿色水处理剂从而成了研究的热门.目前对有机阻垢缓蚀剂缓蚀的机理研究还处于初步的假说阶段.文章采用尿素和马来酸酐为原料合成PASP,其平均分子量可达10000以上.通过测量PASP在不同pH、温度、时间,以及与无机缓蚀剂进行组合后的年腐蚀率和根据实验中的一些现象,对PASP的缓蚀机理进行了一些讨论. 相似文献

Amino acid modified polyaspartic acids were evaluated as calcium-scale inhibitors. Feasibility of scale inhibition experiments was analyzed by molecular dynamics simulation and Gaussian optimization, and the scale inhibition mechanism was theoretically analyzed. Scale inhibition performance was studied by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, static scale inhibition experiments, and electrochemical performance testing, which provided an experimental basis for the molecular dynamics simulation. The experimental results showed that Arg-SA-PASP has better scale inhibition and corrosion inhibition performance than His-SA-PASP. The scale inhibition effect increased with increasing concentration. Electrochemical tests indicated that Arg-SA-PASP is an excellent scale and corrosion inhibitor. 相似文献

TH-682是-种新型缓蚀阻垢剂,具有含磷低,缓蚀阻垢性能好的特点。对全国五大水域水质,特别是南方水系的超低硬度、腐蚀性较强的水质,TH-682具有良好的缓蚀效果;加药量为60mg/L时,其碳钢腐蚀速率均符合GB50050--2007标准。不同药剂量下,TH-682的静态阻垢率均高于HEDP、ATMP和国外药剂-A。通过电厂低硬度、强腐蚀水现场应用一年,TH-682的缓蚀阻垢效果良好。并且TH-682含磷低,仅为4.8%,可以有效避免磷的水中富营养化问题。 相似文献

Peracetic acid (PAA) is a highly potent disinfectant, exhibiting an outstandingly broad spectrum of activity against various microorganisms and viruses. Nevertheless, one disadvantage when applying PAA for disinfection purposes is the strongly corrosive effect due to its oxidizing properties. The employment of a nonionic surfactant as corrosion inhibitor was evaluated in addition to adjustment of the pH value of the solution, regarding the materials aluminum, stainless steel, copper, brass, polyvinyl chloride, wood, and ceramics. Whereas unmodified PAA solution led to strong corrosive effects on the material surface, this impact was significantly lowered when the pH value was shifted to 7. When in addition a nonionic surfactant was applied, no corrosion phenomena at all were observed. 相似文献
