Reclaimed water refers to water that after proper treatment of sewage reaches the water quality indicator , meets certain usage requirements, and can be used beneficially. The water is rich in microorganisms, salt ions, organic and inorganic acids and alkalis, and the temperature difference between day and night, etc., which make the concrete structure face a harsh corrosive environment. Concrete structures have many tiny channels or holes, and water and other substances can easily enter the interior and corrode the binders, aggregates, steel bars, etc. What is more important to note is that when some substances enter the concrete, they will react, causing the concrete structure to expand and force it to crack. Corrosion factors, namely moisture, oxygen and ions (such as chloride ions ) penetrate into the concrete, and the steel bars will rust, further leading to the deterioration of the concrete.
Therefore, the selection and use of anti-corrosion coating for reinforced concrete in recycled water plants is very critical. There are also strict requirements for the use of anti-corrosion coatings on the concrete walls of water plant pools.
Whether it is a reclaimed water plant or a sewage treatment plant, the wall of the tank must have an anti-corrosion protective layer. VRA-LM anti-corrosion waterproof coating is a two-component coating material with strong resistance to acids, alkalis, salts, solvents and mineral oil. and other corrosive effects, not sensitive to bacteria, has certain resistance to ozone , high elongation performance, strong crack resistance, easy construction, can be constructed on both dry and wet surfaces, and has high bonding strength with concrete. Use It has a long service life and is an ideal anti-corrosion material for today's water supply and drainage plants, recycled water plants and sewage treatment plants.
