The Research On The Application Of Combined Scale-Corrosion Inhibitors To Water Treatment In Power Plant

Using the corrosion-scale inhibitors with low phosphorus, high scaling, high corrosiveness to treat the circulating cooling water can effectively control the system scaling and corrosion, select some better combinations from six improved groups through the dynamic screening experiment, we discovered that 5# and 1# water quality stabilizer have the greatly strengthened chelation to the filthy ion and have very good dispersible performance to the filthy crystal and the solid particle, so it is one kind of highly effective-duplicate matching water quality stabilizers that quite suit water quality which be used in the power plant. We carried on two dynamic simulation tests and the quality of two kinds of prescription under the same condition were compared and analysed. And then carried on slice test and electrochemistry test.The 5# was confirmed as the best prescription finally.
