Polyurethane lacquer STELPANT coatings for corrosion protection of metallurgical equipment
Specific aggressive environment, the most commonly found in non-ferrous metallurgy is corrosive destruction of structures and equipment is several times higher than in the entire industry. Corrosion protection of metal fund will keep the steel industry, to reduce the risk of accidents, loss of production, the level of pollution. It is now one of the main ways of corrosion protection and, as a consequence, increase the service life and reliability of the facilities in the industry is the use of modern high-performance coatings. The study of domestic and foreign experience shows that the most effective anti-corrosion agents for hard aggressive media metallurgical enterprises are coating systems based on polyurethane polymers. STEELPAINT GmbH German company developed high-tech, efficient system of protective polyurethane coatings Stelpant, which are widely used in Russia to protect the equipment in the oil industry (tanks, pipes, metal) construction (steel and concrete structures), bridge building, chemical industry (tank equipment, piping, apparatus); nuclear and thermal power engineering (piping, heat exchangers, water treatment systems). Investigated the protective properties of polyurethane coatings systems STELPANT in aggressive atmospheres and water chloride solutions. These tests showed a high weather resistance of coatings STELPANT and good performance in the protective effect of corrosive liquids. Coating Systems II...IV can be recommended for the protection of metal piping, equipment from atmospheric corrosion and aggressive environments (acid vapor) etching department of metallurgical enterprises. These coatings are significantly more efficient and technologically advanced, can easily be applied in conditions of high humidity, freezing temperatures (down to -10°C) have the optimal timing of drying, resistant to intense solar radiation.
