What are the requirements for anti-corrosion coatings on air flotation equipment?

In order to ensure the normal use of sewage treatment, all products have strict coating and anti-corrosion processes, such as air flotation equipment. Regardless of the choice of anti-corrosion coatings or construction, it must be carried out according to the specifications; in addition, the reaction tank should be designed in the air flotation, which is closely related to the air flotation effect.
Before painting to prevent corrosion, the carbon steel needs to be derusted on the air flotation equipment. The specific processes used include shot blasting, sand blasting, pickling, etc. The next step is to use air flotation machine to remove rust. Pickling and phosphating treatment, make the corresponding foundation.
The air flotation device can be divided into an underwater part and an underwater part. Paint designs are also different. The first layer of the underwater paint is an epoxy zinc-rich primer, and the second layer is an epoxy mica substrate. Paint, epoxy asphalt primer, fourth coat of epoxy asphalt topcoat.
After the first layer of epoxy zinc-rich primer, the second layer of epoxy mica paint, and the third layer of chlorinated rubber topcoat on the water parts of the air flotation machine are completed, they can meet the standard.
In sewage treatment equipment, the reaction device is an important part of the air flotation device, and this reaction device is actually a reaction pool. Including water inflow from top to bottom, air flotation pool and horizontal reaction pool through baffle reaction.
Although the structure of the reaction tank of the air flotation machine is different, the working principle is basically the same. The water inlet of the air flotation tank and the water outlet of the reaction tank need to be aligned at the same height to avoid docking problems during installation. And the baffle needs to be welded according to the air flotation treatment capacity.
