New amine-type inhibitors for protecting low-carbon steels in hydrogen sulfide-containing neutral media
The protecting action of polethylenepolyamine (PEPA) products was carried out by gravimetric and electrochemical methods in aerated and de-aerated 35 NaCl solutions and simulated waste water containing CaCl/sub 2/, NaCl, NaHCO/sub 3/, Na/sub 2/SO/sub 4/, and KBr, with addition of H/sub 2/S. Gravimetric and electrochemical measurements were carried out and results are presented. The influence on tanning agents on the physicomechanical and photographic properties of the positive emulsion Unibrom, Normal at thermostated aging for two days was shown. The results lead to the conclusion that the use of animals as tanning agents of the emulsion lead to improvement of the physicomechanical properties of the emulsion light sensitive layers.
