Sewage pool waste pool anti-corrosion spraying polyurea special polyurea sprayer

Cesspool treatment works, as the name suggests, is a sewage treatment tank. Most of the sewage ponds are reinforced concrete structures. The main plant wastewater treatment pool is alternating acid and alkali, corrosive chemical sewage, pH value is often between 3-4. If the pool is not protected and protected, it is easy to be corroded by the sewage in the pool, and in a short time the pool wall will be corroded and perforated, seepage phenomenon.

Sewage pool waste pool anticorrosive spraying polyurea special polyurea sprayer construction features

Today, wastewater treatment is still a hot topic in some industries, and we are always looking for better anti-corrosion products to increase durability and reduce economic losses.

Cesspool wastewater tank anticorrosion spraying polyurea special polyurea sprayer construction waterproof anticorrosion products polyurea is the direction of its efforts. It is important to know that there are many types of waterproof anticorrosion products, and the breakdown may have hundreds or even thousands. For the treatment of cesspools, polyurea elastomer (PU) still has certain advantages. Discourse, not compared with other products, only in the field of anti-corrosion, in-depth development of the cesspool wastewater pool anti-corrosion spraying polyurea special polyurea sprayer base quality assurance.

Defects in polyurea coatings are mainly due to incorrect surface preparation and spray application. To avoid possible surface preparation problems, the following measures should be taken:

Moisture (frost or dew) on the substrate will deteriorate the adhesion of 100% solids polyurea coatings to the substrate and cause other defects, so it should only be applied at temperatures 3°C above the dew point temperature, and the substrate must be dry before construction.

Concrete quality

Concrete quality should be checked before construction. If it meets the national standard, the concrete surface should be polished until the floating slurry on the concrete surface is completely removed, and then the holes should be closed by applying 0.5mm putty as a whole.

Check the air holes on the putty surface

Organize a special person to check the concrete surface and find the unblocked pores to be blocked in time. Check back and forth 3-4 times to ensure that there are no air holes on the concrete surface.

Polyurea surface inspection

When spraying, send someone to inspect the surface of polyurea and find problems to repair in time.

Pipes and pre-buried parts that pass through the structure must be pre-buried first. After the spraying is completed, it is forbidden to make holes to destroy the coating.
