This product is specially developed for swimming pool liners and water facilities, using a composite process of high-strength 1000D polyester base fabric and chlorine resistant PVC coating. Professional laboratory tests have shown that its impermeability performance has passed the 0.3MPa water pressure test for 3 hours without leakage, achieving complete waterproof sealing. The color fastness level is ≥ 6, and the color remains bright after 1000 hours of xenon lamp aging test. The material has passed the -30 ℃ low-temperature bending test without cracks, and its temperature resistance range covers from -30 ℃ to+70 ℃. Its tear resistance strength in the warp/weft direction can reach 765/757N/5cm (1500gsm specification), ensuring structural stability under long-term water pressure and pool wall friction.
1. Chlorine resistance and color fastness verification
It is necessary to verify the chlorine aging resistance test report. High quality products need to be soaked in chlorine containing water for 1000 hours, and the tensile strength retention rate should be greater than 85%. At the same time, it is required that the color fastness be ≥ level 6 (ISO 105-B02) to ensure that it does not fade or discolor under long-term sun exposure.
2. Core data of impermeability and strength
It is necessary to confirm that the static water pressure tolerance value is ≥ 0.3MPa (approximately 30000mm), which is the basic guarantee for long-term full water anti-seepage of commercial swimming pools. It is recommended to have a tear resistance strength of ≥ 750N/5cm (1500gsm specification) in the warp/weft direction to resist pool wall friction and pedestrian trampling.
3. Low temperature and installation adaptability
Verify the temperature resistance range (recommended -30 ℃ to+70 ℃) and the low-temperature bending test report to ensure stable environmental conditions throughout the year. Choose a customized width (up to 3.2 meters seamless) based on the size of the pool body and confirm the joint process (high-frequency welding is better than adhesive) to avoid leakage hazards at the joint.
Q: How does this blue PVC swimming pool tarpaulin resist aging in long-term chlorinated water?
Answer: Very stable. Our commercial swimming pool has been in use for 18 months, and the chlorine concentration in the water is typically maintained at 1.5-3.0 ppm. After sampling and testing, the tensile strength retention rate still reached 88%, fully verifying the laboratory data of strength retention rate>85% after 1000 hours of chlorine immersion, without embrittlement or delamination phenomenon.
Q: Does the waterproof and anti-seepage ability last long under full water conditions?
Answer: Extremely reliable. The swimming pool has a depth of 1.8 meters and has been running continuously at full water for more than 500 days, with no leakage points on the bottom or side walls of the pool. The static water pressure resistance value of the material remains stable at over 0.3MPa, far exceeding that of ordinary PVC tarpaulins (usually ≤ 0.15MPa).
Q: Does the blue surface fade significantly under strong outdoor sunlight?
Answer: The color remains excellent. After two full summers of strong ultraviolet irradiation, the color fastness of the tarpaulin still maintains the level 6 standard, with only slight changes in glossiness and no obvious whitening or yellowing phenomenon. The appearance of the pool body is always clean and professional.
