Case of polyurea waterproofing for power plant waste water pond
As an indispensable infrastructure in the power production process, the stability and durability of the power plant wastewater tank are crucial for the normal operation of the power plant. Due to the use of concrete structures in wastewater tanks and the presence of certain corrosive components in wastewater, waterproof and anti-corrosion treatment is particularly important. Among numerous waterproof materials, polyurea waterproof coating has become an ideal choice for waterproofing power plant wastewater tanks due to its unique advantages.
Characteristics of Polyurea Waterproof Coating
1. Excellent waterproof and anti-corrosion performance: Polyurea waterproof coating has excellent waterproof and anti-corrosion properties, which can effectively cope with the corrosive environment in wastewater tanks and ensure structural safety.
2. Superior wear resistance: Even under long-term water erosion and mechanical wear, polyurea coatings can maintain good integrity and performance.
3. Convenient and environmentally friendly construction: The solid content of the coating is high, the surface dries quickly, and it is not easy to produce sagging during construction, making it very suitable for outdoor operations. At the same time, the construction process of polyurea coating reduces harm to human health and environmental pollution.
4. Weather resistant and impact resistant: Polyurea coating has excellent weather resistance and impact resistance, and can be immersed in water for a long time without cracking or delamination.
5. Strong adhesion: The adhesion between the coating and the concrete substrate is strong, and the bonding is firm, ensuring long-lasting waterproof effect.
6. Low temperature construction: Polyurea coating can be applied under low temperature conditions of -10 ℃, providing convenience for winter construction.
Construction Plan for Polyurea Waterproofing of Power Plant Wastewater Tank
Surface pretreatment
Before spraying polyurea waterproof material on the surface of power plant waste water pond, strict surface pretreatment of concrete substrate must be carried out. The quality of pretreatment effect directly affects the performance of sprayed materials. Therefore, surface cleaning, grinding, repairing and other works must be carried out in accordance with specification requirements to ensure that the substrate surface is flat, clean, free of oil stains and loose substances.
construction equipment
The polyurea waterproof construction project of power plant waste water pond is generally large in scale, so high-pressure airless spraying equipment is needed for construction. This equipment can ensure a uniform and dense coating and improve construction efficiency and quality.
Construction process
1. Primer spraying: Firstly, spray a layer of primer on the surface of the pre treated substrate to enhance the adhesion between the coating and the substrate.
2. Polyurea coating spraying: Subsequently, the polyurea coating was evenly sprayed onto the primer using high-pressure airless spraying equipment. The coating quickly solidifies in an instant, forming a high-strength, high elongation, seamless and highly elastic waterproof coating film.
3. Inspection and repair: After the construction is completed, a comprehensive inspection of the coating is required to ensure that there are no defects such as holidays, bubbles, cracks, etc. If any are found, they should be repaired in a timely manner.
