How does the dissolved air flotation machine be anti-corrosion and anti-rust during long-term use?

So we must first understand why anti-corrosion treatment is required?
The external components of the dissolved air flotation machine directly determine the quality and service life of the equipment, including the water pump. steel. Air compressor etc. The anti-corrosion treatment of the air flotation equipment will be directly related to the service life of the whole set of equipment, which is very important, because the equipment has been in contact with water for a long time, and coagulants are added to the water, which will inevitably be corrosive to a certain extent, so it must be It is necessary to do a good job of anti-corrosion treatment to isolate the steel from water and air.
The key parts of anti-corrosion treatment are welding and drilling, etc. If these parts do not have anti-corrosion treatment, it is easy to corrode the life of the whole set of equipment.
The materials of the dissolved air flotation machine are mainly carbon steel and stainless steel. Stainless steel is generally used in the food industry, but due to cost reasons, most of them use carbon steel, but if carbon steel is used as the raw material of the box, it is corrosion-resistant The performance is poor, usually there will be rust in about two years, the light condition can be repaired, and the serious condition can be directly damaged. It will also seriously affect work efficiency.
Next, let's share some methods and common sense that can improve the anti-corrosion and anti-rust of dissolved air flotation machines.
1. Primer + intermediate paint + top coat: ordinary epoxy zinc-rich primer + epoxy intermediate paint + various colors of chlorinated rubber top coat (anti-corrosion life can reach 5-8 years)
2. Primer + intermediate paint + topcoat: ordinary epoxy zinc-rich primer + thick film epoxy miracic iron intermediate paint + various colors of chlorinated rubber topcoat (the anti-corrosion period can reach 5-8 years, depending on the situation of the ground) The difference is that this package can increase the film thickness)
3. Primer + intermediate paint + top coat: ordinary epoxy zinc-rich primer/epoxy zinc phosphate primer/epoxy iron red primer + epoxy cloud iron intermediate paint + acrylic polyurethane topcoat of various colors (the anti-corrosion period can reach 6-8 years)
4. Primer + top coat: Hongdan antirust paint + alkyd enamel of various colors (corrosion life can reach 2-3 years)
5. Primer + intermediate paint + top coat: ordinary epoxy zinc-rich primer + epoxy intermediate paint + various colors of aliphatic polyurethane top coat (corrosion life can reach 6-8 years).
