1. Requirements for anti-corrosion materials in wastewater treatment plants: a. The coatings should possess excellent comprehensive properties, including physical and mechanical properties, resistance to chemical agents, and suitability for application processes. b. The paint types should be advanced and new. c. It should have a long service life based on cost-effectiveness (at least 5 to 8 years). 2. Criteria for selecting anti-corrosion materials: a. Application experience of anti-corrosion coatings in domestic and international sewage treatment projects. b. Domestic paint varieties with excellent comprehensive performance. c. Relevant design standards and specification manuals. d. The actual requirements of the owner. 3. Principles for comprehensive evaluation: When selecting anti-corrosion materials for wastewater treatment projects based on the environmental conditions, a comprehensive evaluation should be carried out considering the following three operating conditions: a. Atmospheric environment: weather resistance, salt spray resistance ； corrosion resistance ； Shiny, attractive, and easy to clean ； It has good physical and mechanical properties as well as excellent workability. b. Liquid phase: corrosion-resistant ； impermeability ； It has good physical and mechanical properties as well as excellent workability. c. Alternation of wet and dry conditions: The requirements are primarily related to the liquid phase, taking into account factors such as weather resistance and aesthetics in the atmospheric phase as well.
