Impeller blade corrosion causes and anti-corrosion strategy First of all, from the media PH, temperature, flow rate, salt concentration, microbial content, dissimilar metal combinations and media wear and tear angle analysis of the impact of impeller blade corrosion of various factors, combined with modern anti- In a reasonable choice of materials, manufacturing processes and SNT anti-corrosion coating brushing and other factors comprehensive analysis of corrosion resistance.
There are two kinds of wear and corrosion caused by the common action of the impeller blade friction, the transmission medium and the relative motion of the impeller blade surface. The shear stress of the moving medium on the blade surface and the high-speed flow wear friction make the metal loss of the impeller blade, Two kinds of anti-corrosion coating, a impeller blade in the liquid slurry friction corrosion, the choice is SNT-508 wear waterproof coating; one is in the dust smoke friction corrosion, the choice is SNT-505 flue gas anti-corrosion coating, two High-performance heavy-duty high-hardness coating, are Shi Naite's outstanding paint, brushing in the impeller blade protection effect, you can extend the impeller blade 3-8 times the service life.
High-tech paint synthesis technology, the use of ceramic high-temperature coating technology, Zibo Schneider anti-corrosion Technology Co., Ltd. developed a high temperature SNT-508 wear-resistant waterproof coating, raw materials using ionic compounds and some synthetic covalent compounds, ion bonds and covalent bond Is a strong bond, and the combination of the system due to the use of composite measures and special treatment to form a chemical combination, so the strength and stiffness is great, can effectively resist the high-speed impact and shear stress, the strength of up to 200Mpa above the hardness of manganese Steel more than 10 times, the temperature can reach 600 ℃ high temperature. Can be used for impeller blades in the cavitation friction, hardness friction and impact friction and other wear-resistant environment, to extend the life of the impeller blades.
In order to improve the anti-thermal denaturation, abrasion resistance and adhesion of the impeller blade coating, Schneider uses nano-powder, Schneider smoke anti-corrosion coating super-strong adhesion, the coating and the substrate is very strong, excellent Corrosion resistance, anti-flue gas H2S and other media corrosion, acid corrosion, temperature corrosion. The flue gas anticorrosive coating has a strong adhesion to the matrix, and the flue gas anticorrosive coating composition contains the metal oxide nanomaterials and the rare earth oxide ultrafine powder to help the coating form a dense interfacial transition layer Thermodynamic properties and matrix to match, strong adhesion. Flue gas anti-corrosion coating base materials and fillers are high temperature of the inorganic composition, heat 750 ℃. Flue gas anti-corrosion coating composed of a variety of components of the ceramic functional filler, together with the coating to give the coating excellent wear and corrosion resistance, the effective protection of the impeller leaves in the flue gas, dust friction corrosion, protection of the impeller blades.
