Отраслевое применение Запросить расчет системы
Очистные сооружения и бетонные емкости
Подбор покрытий для влажных, химически нагруженных и трудно обслуживаемых бетонных объектов.
Applicable Standards
ISO 12944 GB 50046-2008 industrial building corrosion protection design reference
Application Scenarios
Municipal sewage treatment pools, industrial wastewater pools, chemical storage pools, and other anti-corrosion and waterproof coating applications.
Selection Logic
Wastewater and sewage environments need coating systems that consider immersion, chemical exposure, moisture, cleaning procedures, and substrate movement. Atmospheric ISO 12944 class is only one reference; immersion and chemical resistance must be reviewed separately.
Recommended Coating Systems
| Coat | Product | Coats | DFT (μm) |
|---|---|---|---|
| Primer | Epoxy Anti-Corrosion Primer | 1 | 60-80 |
| Intermediate | Epoxy MIO Intermediate Coat | 1 | 80-100 |
| Topcoat | Epoxy Anti-Corrosion Topcoat | 2 | 100-120 |
| Total | 240-300 |
Surface Preparation
- Blast cleaning Sa2½
- Surface roughness Rz 50-85 μm
- Cleanliness: Free of oil, dust, and contaminants
Design Life Reference
Design service life: 10-15 years.
Related ISO 12944 Classes
- C4-C5: exposed steel around wastewater facilities and high-humidity process areas.
- Immersion or chemical service: confirm lining compatibility, curing conditions, and current TDS/SDS before quotation.
