Problems solved by technology

The anti-corrosion of the sewage tank is essentially the anti-corrosion of its inner lining. Traditionally, anti-corrosion coatings or anti-corrosion FRP are often used for the anti-corrosion of the inner lining of the sewage pool. Although these traditional methods have certain effects, they still have certain limitations. For example, simply using anti-corrosion The coating is applied to the lining of the sewage tank, and the thickness of the coating layer is limited. If it exceeds a certain thickness, the anti-corrosion coating is easy to crack, which is not conducive to anti-corrosion. The limited thickness brings potential hidden dangers to anti-corrosion. The shedding surface of the entire anti-corrosion layer may gradually expand accordingly, and finally fall off completely. Even if it does not fall off completely, the part that falls off may cause the overall anti-corrosion failure
FRP anti-corrosion Although the strength of the anti-corrosion layer has been improved, even if it is partially damaged, the entire FRP anti-corrosion layer will not be damaged, but the amount of anti-corrosion resin in FRP is limited, and the anti-corrosion effect is not good.
In addition, whether it is coating anti-corrosion or FRP anti-corrosion, the anti-corrosion resin used is a single
However, the corrosion components in the sewage pool are relatively complex, and it is difficult for a single resin to prevent multiple corrosive substances from corroding it at the same time. continuous use of the pool
