Deterioration Inhibitor
by Tam

They found empirically by direct corrosion tests. Over the past decade, significant progress in the development of scientifically based selection of the adsorption inhibitors, and understanding the mechanism of their protective action. The proposed theory is based, inter alia, on account of the nature of the metal (transition or intransitive), the metal charge in relation to the solution and charge of the particles of the inhibitor, the excitation energy of the metal electrons and molecules of the inhibitor, metal accessories and an inhibitor to the class of hard or soft acids and bases. These approaches allowed with reasonable certainty argue that the most effective adsorption inhibitors of acid corrosion in a different sign of charge of the metal particles and the inhibitor in the presence of highly mobile electrons easily excited by the inhibitor in combinations of metal – mild acid inhibitor – a mild base or metal – harsh acid inhibitor – rigid foundation. Corrosion inhibitors can effectively inhibit the process of hydrogenation metals acid corrosion by preventing the deterioration of their mechanical properties. Moreover, there are cases where even the strength of the metal increases with etching, and the hydrogen content is reduced compared with netravlenym metal, which helps to extend product life and reduce their thickness. The introduction of inhibitors for fuels and lubricants, not only reduces their corrosion, but also reduces wear due to friction and vibration. High versatile protective properties of inhibitors of their widespread commercial production. The volume of world production and consumption of corrosion inhibitors, lubricant additives is 4.4 million tons / year with a tendency to increase to 5.5-6.0 million tons / year. Of this amount: the inhibition of oil, gas, produced water and other environments in oil and gas industry – 20-25%, the preparation and processing of oil – 2-5 on the inhibition of oil production and protection of oil-based – 65-75, for other needs (inhibition of acid cooling media, etc.) – 3-5%.
