A Review of Stress Corrosion Cracking of Welded Stainless Steels

Ekaterina A. Krivonosova
This article gives a brief review of scientific researches of high-alloyed chromium-nickel steels stress corrosion cracking (SCC) process of welded joints. Welded joints are one of the most complex objects from the standpoint of the general theory of corrosion fatigue of metals. During their operation a number of problems arise related to the heterogeneity of the material properties, the complexity of the structure, the presence o

Comparison between Modeling of Cetirizine Solubility Using Different Approaches: Semi-Empirical Density Based Correlations vs. Peng-Robinson EoS

Mostafa Lashkarbolooki, Ali Zeinolabedini Hezave
The tunable nature of the solubility of various compounds, including molecules of pharmaceutical and biological interest, in supercritical fluids (SCFs) makes SCF extraction technology attractive for many separation and purification processes. Among the different influencing parameters, the most important one in the supercritical based processes is the knowledge of solubility of model solute. But, experimental measurement of the solubility of all pharmaceuticals in wide ranges of temperature and...

Gaskets with Expandable Graphite Treated with Nitric, Sulphuric, Phosphoric Acids and Ferric Chloride

Heinrich Horacek
The task was to find out the most appropriate expandable graphite intercalation compound GIC for intumescent seals. The application in fire seals required GICs, which exerted high expansion at low burning rates. Therefore graphite was treated with nitric, sulphuric, phosphoric acids and ferric chloride. Phosphoric acid with its flame retardant properties was the favourite, but graphite treated with it, did not exfoliate, therefore expandable graphite was post treated with phosphoric acid. Elemen...

Preparation and Fire Test of Intumescent Powder Coatings

Heinrich Horacek

New regulations for hazardous air pollutants drove operations to compliant coatings. Powder coatings were the most popular choice. A screening of intumescent powder coatings was carried out comprising binders like thermoplastics as plasticised polyvinylchloride and polypropylene as well as non-cross linked thermosets as polyurethanes. Intumescence was achieved by addition of the intumescent ingredient bicyclopentaerythritol phosphate, by the intumescent

Determination of Carbon Oxide in Exhausts of Vehicles by Thermocatalytic Method

E. Abduraxmanov,М. М. Sultanov,G. N. Daminov,S. U. Tillayev
Selective methods of thermocatalytic determination of carbon oxide and hydrocarbons in exhaust gases of vehicles are based on measurement of different thermo effects of oxidation of a combustible mixture, obtained from two identical thermosensible elements working at different temperatures are developed. At one temperature there is an oxidation of all analyzed gas mixture, and on another—the mixture without a selectively determined component and by the difference of thermo effects an exact conce...
