Three measures for anti-rust and anti-corrosion treatment of dissolved air flotation

1. Surface derusting of carbon steel with dissolved air flotation: shot blasting, sandblasting; derusting by air flotation machine, etc. Sa2.5.
2. Coating of the underwater parts of the air flotation machine: one layer of epoxy zinc-rich primer, one layer of epoxy miracite primer, the third layer of epoxy asphalt primer, and the fourth layer of epoxy asphalt topcoat.
3. Coating of the above-water parts of the air flotation machine: one layer of epoxy zinc-rich primer, one layer of epoxy miracic iron primer, and the third layer of chlorinated rubber topcoat.
After the stainless steel parts of the dissolved air flotation are processed, the surface passivation treatment is carried out. If the coating is damaged during transportation and installation, it must be repaired in strict accordance with the coating process to ensure its quality level. The anti-corrosion of the air flotation machine is to protect the metal objects that are easy to rust by adopting various means to achieve the purpose of prolonging its service life. Usually, physical anti-corrosion, chemical anti-corrosion, electrochemical anti-corrosion and other methods are used for the anti-corrosion work of the air flotation machine. , but the anti-corrosion work of the air flotation machine must be operated correctly according to the actual situation.
