Study on the performance of fluorescence traced scale & corrosion inhibitor
Online published: 2010-10-01
The performance of the carboxylate polymer containing naphthalamine fluorescence radical group has been evaluated by means of fluorescent spectrum,static scale inhibition and rotation specimen methods. The results indicate that a definite linear relationship between the fluorescence intensity and concentration of the fluorescence traced polymer is shown,and it has very good calcium carbonate scale inhibiting capacity. Its performance is corresponding to that of maleic anhydride-acrylic acid copolymers in markets,and is a bit inferior to PBTCA. After it has combined with BTA and other corrosion inhibitors and formed inorganic phosphorus corrosion inhibition prescription,and in the water quality environment of a water area in Yunnan Province,it has pretty good corrosion inhibiting effect on brass,the highest corrosion inihbiting rate is higher than 98%.
Key words: fluorescence polymer; scale inhibition; corrosion inhibition
