Abstract
<p>Inhibition properties of a number of glass-like polyphosphates on 65J steel were investigated using the gravimetry and methods potassium nitrate solution polarization curves in a 0,1M (pH=6,05). The possibilities<br />of optimum experimental conditions were considered as well. Basing on the experimental data the inhibition coefficient and protective effect were found. The inhibiting action of polyphosphates, apparently, is due to the formation of inhomogeneous protecting film on the steel surface.</p>
Highlights
Reconstruction and further development of many branches of Kazakhstan’s industry - petrochemical, chemical, power, metallurgical and others - are closely connected with the improvement of their water-supply systems, the increase of the role of return watersupply, changing over to closed and waste-free industrial systems.In this connection the problem of anticorrosive protection of such metal constructions as water cooling and domestic drinking water-supply systems becomes very urgent
As practice has showed the reduction of their service life as compared with that specified in the standards is caused by their corrosive destruction
The search for effective anticorrosive measures aimed at the increase of service life of different types of water supply systems and saving of the metal ressources of the country is a very actual problem [2]
Summary
Reconstruction and further development of many branches of Kazakhstan’s industry - petrochemical, chemical, power, metallurgical and others - are closely connected with the improvement of their water-supply systems, the increase of the role of return watersupply, changing over to closed and waste-free industrial systems. In this connection the problem of anticorrosive protection of such metal constructions as water cooling and domestic drinking water-supply systems becomes very urgent. The search for effective anticorrosive measures aimed at the increase of service life of different types of water supply systems and saving of the metal ressources of the country is a very actual problem [2]. To solve the problem of reliable and long-term protection of different types of water supplies against internal corrosion, it is very important to choose scientifically justified protection technique
