There are a wide variety of corrosion-resistant materials, and the most commonly used coatings include epoxy, epoxy asphalt, asphalt, polyurethane, chlorinated rubber, chlorosulfonated polyethylene, polyvinyl chloride, perchloroethylene, and alkyd resins. In recent years, newly developed glass flake coatings that use epoxy, epoxy asphalt, vinyl resin, chlorinated rubber, polyurethane, and similar substances as their main film-forming components have been successfully applied in various anti-corrosion projects. These coatings offer excellent shielding capabilities and strong impermeability, making them suitable as long-lasting anti-corrosion coatings. Abroad, the corrosion protection for industrial and domestic wastewater mainly relies on two categories: PVC linings and coatings. In sewage engineering, coatings such as epoxy, epoxy asphalt, zinc-rich coatings, polyurethane, and asphalt are commonly used ； Glass flake coatings are widely used in sewage treatment projects. Currently, there are many anti-corrosion measures available for domestic sewage projects under such specific environmental conditions, but the use of ordinary coatings alone usually yields unsatisfactory results. **Standard GB50046, the \"Code for Corrosion Prevention Design of Industrial Buildings,\" specifies requirements for corrosion prevention in sewage treatment tanks, considering glass flake coatings to be an ideal material for this purpose.
