Impellers Thermal Denaturation, Abrasion Resistance And Adhesion
Aug 04, 2017

Impellers blade corrosion causes and anti-corrosion strategy First of all, from the media PH, temperature, flow rate, salt concentration, microbial content, dissimilar metal combination and medium wear angle analysis of the impact of Impellers blade corrosion of various factors, combined with modern anti- In a reasonable choice of materials, manufacturing processes and ZS 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 Impellers blade friction, the transmission medium and the relative motion of the Impellers 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 Impellers blade, Here is recommended two kinds of anti-corrosion coating, a leaf blade in the liquid slurry friction corrosion, the choice is ZS-911 wear waterproof coating; one is in the dust smoke friction corrosion, the choice is ZS-1041 flue gas corrosion coating, Two high-performance heavy-duty high-hardness coating, brushing in the Impellers blade protection effect is good, you can extend the Impellers blade 3-8 times the service life.

High-tech paint synthesis technology, the use of ceramic high-temperature coating technology, and now  developed a high temperature ZS-911 wear waterproof coating, raw materials using ionic compounds and some synthetic covalent compounds, ionic bond and covalent bond is strong Combined with the key, and the combination of the system due to the use of composite strengthening measures and special treatment, the formation of chemical combination, so the strength and stiffness is great, can effectively resist the high-speed impact and shear stress, its strength up to 200Mpa or more, hardness is manganese steel More than 10 times, the temperature can reach 600 ℃ high temperature. Can be used for Impellers blades in the cavitation friction, hardness friction and impact friction and other wear-resistant environment, to extend the life of the Impellers blades.

In order to improve the anti-thermal denaturation, abrasion resistance and adhesion of the Impellers blade coating, , coating and matrix binding force is extremely strong Corrosion resistance, anti-flue gas H2S and other media corrosion, acid corrosion, temperature corrosion. ZS-1041 flue gas anticorrosive coating and substrate binding force is very strong, Fengtai District East Tieying  gas anticorrosive coating composition contains metal oxide nano-materials and rare earth oxide ultrafine powder to help coating Forming a dense interface transition layer, so that its integrated thermodynamic properties and matrix to match, strong adhesion. ZS-1041 flue gas corrosion coating base material and filler are high temperature of the inorganic composition, heat 750 ℃. 1 flue gas anti-corrosion coating composed of a variety of components of the ceramic function filler, to jointly cooperate with the coating to give excellent wear and corrosion resistance, the effective protection of the Impellers blades in the flue gas, dust friction corrosion, protection Impellers leaves.
