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.

Blog Professional evaluation data interpretation: PVC waterproof covering cloth This product is compounded with high density polyester base cloth and modified PVC coating. It has been systematically verified in the laboratory that its hydrostatic pressure value is ≥ 8000mm (ISO 811), which can achieve complete isolation in the continuous rainstorm environment. After 2000 hours of xenon lamp aging test, the tensile strength retention rate is greater than 85% (GB/T 16422.2), and the UV resistance performance is excellent. The dynamic abrasion resistance test (ASTM D4966) showed that the fabric remained undamaged after 50000 frictions and passed the -25 ℃ low-temperature bending test without cracks. The surface has undergone anti mold treatment (Grade 0, GB/T 24346), suitable for long-term coverage scenarios such as warehousing, agriculture, outdoor equipment, etc., and can maintain stable performance even in humid and hot environments. PVC waterproof covering cloth selection guide 1. Waterproof rating and durability dataThe preferred product is one with a hydrostatic pressure value of ≥ 8000mm (commonly available on the market at around 3000-5000mm). It is necessary to check the wear test report. Professional grade fabrics should meet the requirement of ≥ 50000 times of friction without damage, far higher than conventional standards, to ensure long-term use without water leakage and scratch resistance.2. Weather resistance and aging resistanceRequest UV resistance test data, high-quality materials must pass a 2000 hour xenon lamp aging test and maintain a tensile strength retention rate of>85%. At the same time, confirm the anti mold level (recommended level 0) to avoid the growth of mold in humid and hot environments that may cause performance degradation.3. Environmental adaptability verificationAccording to the climate of the usage area, verify the low-temperature flexibility test (it is recommended to bend at -25 ℃ without cracks). For long-term outdoor coverage, it is recommended to choose thickened models with a weight of ≥ 500g/㎡, and ensure that the edges have high-frequency welding or double-layer seam reinforcement to improve wind resistance and structural life. Q: What is the actual waterproof effect of this PVC waterproof cloth during continuous rainy seasons?Answer: The effect is very reliable. We have been covering the open-air storage of building materials for over two months and have experienced multiple periods of continuous heavy rainfall. The static water pressure value remained stable above 8000mm, and the material under the fabric remained completely dry without any leakage points.Q: After long-term outdoor use, is the anti-aging performance of the material as shown in the data?Answer: The performance fully meets expectations. The waterproof cloth has been in use for three years, and after simple testing, its tensile strength retention rate is still close to 87%, with no obvious brittleness or discoloration on the surface, verifying the reliability of its 2000 hour xenon lamp aging test.Q: Is it easy to mold in humid environments? Is cleaning and maintenance convenient?Answer: The anti mold effect is excellent. After use during the humid season in the south, there is no mold growth on the fabric surface. The surface is smooth, and ordinary dust can be cleaned by washing with rainwater. Stubborn stains can be removed by wiping with a damp cloth, making maintenance very easy.
