    "Polyurethane foam"
    Concrete sewage treatment tanks include sedimentation tanks and ponds. Contact pond, anaerobic pond, concentration pond, sand pond, etc. In the sewage treatment tank, a large amount of sewage containing corrosive media, such as acid, alkali, and salt industrial wastewater, organic matter and oxidants; rainwater and sewage in oxidation ditch, adding microorganisms and chlorine will also corrode reinforced concrete to some extent; The oxygen concentration in the water changes frequently, and the difference in oxygen concentration between the same pools will cause the corrosion of the battery with different concentrations. On the other hand, due to the coagulated composition and microporous structure, it faces leaching corrosion, alternating current corrosion, and crystalline corrosion, causing solidification and corrosion cracking of the steel bar. Non-corrosive treatment of concrete structure treatment tanks will generally show concrete surface damage within a month, which will greatly reduce the strength of concrete structures.
    Therefore, the anti-corrosion maintenance of the new wall concrete structure is very necessary. It is reliable and simple to apply a layer of coagulation adhesion, weather resistance, impermeability, high performance non-toxic, and durable heavy anti-corrosion coating.
    Concrete structure anticorrosive and waterproof coating is a water-soluble green two-component coating performance anticorrosive coating, which has excellent adhesion and flexible concrete, a compact coating on the outside, acid and alkali resistance, salt spray resistance, organic solvents, outstanding overall performance. It is mainly used for anticorrosion of concrete structures in corrosive environments.
    The concrete structure anticorrosive and waterproof coating uses water as the solvent, has no pollution, and does not have high environmental requirements. The coating can be applied on the surface of boring and wet concrete. After construction, it has high elasticity and can resist the corrosion leakage caused by concrete microcracks! Easy construction, fast film formation, strong adhesion and high cost performance.
