sewage treatment plant mainly undertakes the task of treating industrial sewage. The sewage contains a large amount of emulsified fatty acids and aromatic hydrocarbon polymer compounds, and the mass fraction of the solid is between 10% and 15%. The entire sewage treatment plant has multiple sewage treatment tanks of reinforced concrete. Because the inner wall and bottom of the pool are eroded by high concentration and multi-component sewage, abrasion of solid particles, corrosion of microorganisms and reinforced concrete structures, cracks appear, and leakage occurs at these cracks, construction joints and expansion joints and .
also leaks from the sheets at the anchors of the installation equipment. These leakages have caused serious pollution to the surrounding environment. In addition to cracks, some concrete protective layers of are harsh in some places where the steel bars are corroded and cause large local damage. Choosing a reasonable waterproofing system and formulating corresponding construction processes are the key to concrete maintenance, which directly affects the life of concrete structures. Reasonable protection of concrete is the key to solving the above problems. Choosing the right coating is the top priority. Yantai Lumeng's VRA-LM composite anti-corrosion waterproof coating is the choice to solve this problem.
Traditional anticorrosion paints are divided into cumbersome construction processes, and most of them are solvent-based coatings , and most of the resins used are epoxy series products. These coatings become rigid after curing and have poor impact resistance. If used for concrete corrosion protection, the base layer is required to be very dry before construction can be constructed, which pollutes the environment during construction and has no crack resistance.
VRA-LM composite anti-corrosion waterproof coating is a water-based anti-corrosion coating with high acid and alkali resistance and corrosion resistance. It extends the service life of the sewage pool, has high coating hardness, wear and impact resistance, and has a long acid and alkali aging time. It can be constructed on both dry and wet surfaces of concrete. The coating after construction is highly elastic and can resist leakage and corrosion caused by fine cracks in concrete! Convenient construction, fast film formation and strong adhesion. The damaged concrete structure was repaired and anti-corrosion treatment, extending the life of reinforced concrete. Extending its service life has important practical significance for the current sewage tank.
