The standard name for impermeable membrane is polyethylene geomembrane, which is mainly made of a milky white semi transparent to opaque thermoplastic resin material - polyethylene resin. It is widely used in anti-seepage projects such as artificial lakes, reservoirs, fish ponds, and reservoirs. So what are the advantages of using impermeable membranes in fish ponds?

1. High anti-seepage coefficient - The anti-seepage membrane has an anti-seepage effect that ordinary waterproof materials cannot match. The anti-seepage

membrane has high strength and tensile mechanical properties, and its excellent elasticity and deformation ability make it very suitable for the expansion or

contraction of the base surface, which can effectively overcome the uneven settlement of the base surface.

2. Chemical stability - The anti-seepage membrane has excellent chemical stability and is currently widely used in aquaculture. Resistant to high and low

temperatures, corrosion from over 80 strong acid and alkali chemical media such as asphalt, oil and tar, acid, alkali, salt, etc

3. Aging resistance - The impermeable film has excellent aging resistance and UV resistance due to the addition of 2% and 3% carbon black in the production

raw materials, and can be used naked.

4. Low cost and high efficiency - The anti-seepage membrane adopts new technology to improve the anti-seepage effect, but the production process is more

scientific and fast, so the product cost is lower than traditional waterproof materials. According to actual calculations, the use of impermeable membranes in

general engineering can save costs by about 30% -50%.

5. Fast construction speed - The anti-seepage membrane has high flexibility and comes in various specifications and laying forms to meet the anti-seepage

requirements of different fish ponds. Adopting hot melt welding, the weld strength is high, and the construction is convenient, fast, and healthy.

6. Environmental Protection - The materials used for the anti-seepage membrane are all environmentally friendly. The principle of anti-seepage is a common

physical change without any harmful substances. It is a reasonable choice for aquaculture such as fish ponds, shrimp ponds, and lotus ponds.
