Spray polyurea for Sewage treatment tank
PS500D seamless spray polyurea solves sewage tank acid/alkali leakage issues. Fast curing, 2.0mm thick, 15+ years service life, cuts maintenance cost & construction time by 50%. Eco-friendly anti-corrosion coating for wastewater pools.
Due to long-term contact with acidic/alkaline substances, microorganisms and salts in sewage treatment ponds, the traditional waterproof layer (such as asphalt, coil) has the following problems:
1: coating cracking, leakage, affecting the efficiency of sewage treatment;
2: Frequent maintenance leads to increased operating costs;
3: Lack of corrosion resistance of traditional materials, life is only 2-3 years.
Solution: PS500D spray polyurea waterproof and anticorrosive system
The PS500D is recommended for spraying polyurea elastomers, the core benefits of which include:
✅ super corrosion resistance: resistant to pH 3-11 acid and alkali environment and corrosive media;
✅ Seamless waterproof: 100% solid content, no seams, completely eliminate leakage;
✅ Fast construction: instant curing (5-10 stopwatch dry), shorten the construction period by 50%;
✅ Long life: design service life ≥15 years, reduce the whole cycle cost;
✅ Environmental protection and non-toxic.
Construction Process：
1: Base surface treatment: polish the original damaged layer, clean and repair cracks;
2: Undercoat construction: spray special Primer to enhance adhesion;
3: Polyurea spraying: mechanized spraying PS500D, thickness 2.0mm±0.2mm;
4: Quality detection: through the electric spark detection (no leakage point), thickness meter sampling.
Project Value：
1: The leakage rate is reduced: 100% no leakage (the original system annual leakage rate of 5%);
2: Maintenance cost reduction: no major repair is expected in 10 years;
3: Shorten the construction period: 7 days to complete the construction;
4: Ensure the stable operation of the sewage treatment system to avoid secondary pollution caused by leakage;
5: Help customers achieve green factories through the application of environmentally friendly materials.
Application Scenario:
This case scheme can be extended to: industrial wastewater ponds, drinking water storage tanks, chemical workshop floors, offshore platforms and other harsh corrosive environments.
