Advantages of anti-seepage film for fish pond aquaculture

　　1. High anti-seepage coefficient - the anti-seepage film has an unparalleled anti-seepage effect compared to ordinary waterproof materials, while HDPE anti-seepage film has high-strength tensile mechanical properties. Its excellent elasticity and deformation ability make it very suitable for expansion or contraction of the base surface, effectively overcoming uneven settlement of the base surface;

　　2. Chemical stability - The anti-seepage film has excellent chemical stability and is currently widely used in the aquaculture industry. Resistant to high and low temperatures, asphalt, oil, and tar, as well as corrosion in over 80 strong acid and alkali chemical media such as acid, alkali, and salt;

　　3. Aging resistance - the impermeable membrane has excellent aging resistance and UV resistance due to the addition of 2% -3% carbon black in the production raw materials, which can be used naked;

　　4. Low cost and high efficiency - HDPE anti-seepage film adopts new technology to improve its anti-seepage effect, but the production process is more scientific and fast, so the product cost is actually lower than traditional waterproof materials. According to actual calculations, using HDPE anti-seepage film in general engineering can save about 30% -50% of the cost;

　　5. Fast construction speed - The anti-seepage membrane has high flexibility, with various specifications and laying forms to meet the anti-seepage requirements of different fish ponds. It adopts hot melt welding, with high weld strength, convenient, fast, and healthy construction;

　　6. Environmental friendliness - The materials used for the anti-seepage membrane are all environmentally friendly materials, and the anti-seepage principle is ordinary physical changes that do not produce any harmful substances. It is a reasonable choice for aquaculture industries such as fish ponds, shrimp ponds, and lotus root ponds.
