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: in line with GB/T 17219-2001 drinking water safety standards.

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.
