Application of 0.75mm geomembrane for fishpond liner in Peru-N

² Definition

Geomembrane is a waterproof barrier material based on high polymer. 0.75mm geomembrane refers to the thickness of 0.75mm geomembrane, common materials are high-density polyethylene (HDPE) and so on.

² Peculiarity

1. Excellent impermeability: for example, the permeability coefficient of 0.75mm geomemofilm of HDPE material is ≤1×10⁻¹²cm/s, which can effectively block liquid leakage.

2. Strong corrosion resistance: It has excellent corrosion resistance to more than 80 chemical media such as acid, alkali and salt, and can maintain stability in complex chemical environment.

3. Good mechanical properties: with high tensile strength, generally ≥17MPa, elongation at break ≥700%, can withstand greater tension and deformation without breaking.

4. Good anti-aging: add carbon black and antioxidant, ultraviolet radiation resistance, in the outdoor environment service life can reach more than 50 years.

5. Convenient construction: light weight, good flexibility, easy to cut and install, and the width of up to 6 meters or wider, can reduce the number of joints, reduce the risk of leakage, shorten the construction period.

Market price analysis of 0.75mm geomembrane

0.75mm geomembrane has a high cost performance while meeting the needs of seepage prevention in fish ponds. Compared with some traditional impermeable materials such as concrete, asphalt, etc., the material cost and construction cost of geomembrane are relatively low. Taking a fish pond with an area of 1000 square meters as an example, using 0.75mm geomembrane as a lining, the material cost is about 7000 yuan, plus construction costs, etc., the total investment is relatively economical, and can bring long-term stable use effect.

² Challenges facing fish ponds in Peru

Peru has rich water resources and a suitable climate, which provides good conditions for the development of fisheries. However, traditional fish ponds are faced with many problems in the course of operation. On the one hand, serious leakage of fish ponds leads to waste of water resources and increases operating costs. According to statistics, the annual water loss due to leakage of fish ponds without effective anti-seepage treatment can reach 20%-30% of the total water storage. On the other hand, harmful substances in the soil easily penetrate into the fish pond, affecting the water quality and threatening the health of fish. At the same time, frequent water quality problems also increase the probability of fish disease and reduce the production and quality of fisheries.

² 0.75mm geomembrane importance

In the development of fisheries in Peru, the construction and maintenance of fish ponds are crucial. 0.75mm geomembrane plays an important role in the lining of Peruvian fish ponds. It can effectively prevent seepage, the use of the geomembrane can prevent the leakage of fish pond water, maintain a stable water level, reduce water waste and water replenishment costs. It can also improve water quality, isolate harmful substances in the soil, prevent them from entering the fish pond to affect the water quality, provide a healthy growth environment for fish, reduce the risk of disease, and reduce the use of drugs. At the same time, enhance the stability of the fish pond, protect the slope from water erosion, make the dam more stable, reduce the hidden danger of landslides, and facilitate the cleanup of the pond, improve the fishing efficiency, and help to improve the economic benefits of fisheries.

² 0.75mm geomembrane case study

In the Langostinera Isla Bella shrimp farm project in the Tombes region of Peru, 0.75mm geomembrane played a key role. Most of the local soil is sandy or acidic soil containing pyrite, which has poor water retention and is easy to reduce the pH value of the water body, affecting the growth of shrimp. Meanwhile, organic soil is not conducive to the construction of stable dykes, and faces the problems of drainage and pond bottom drying.

After using 0.75mm geomembrane, it effectively isolates pond water and soil, avoids water leakage, maintains stable water level, and reduces water refill cost. Its excellent corrosion resistance blocks the infiltration of harmful substances in the soil, improves water quality, reduces the growth of bacteria, reduces the risk of disease in shrimp, and reduces the use of antibiotics. geomembrane also enhance the stability of pond slopes, prevent water erosion, facilitate the cleaning of sediment and waste at the bottom of the pond, improve fishing efficiency, and ultimately achieve a significant increase in shrimp production, highlighting the important value of the application of fish pond lining in Peru.

² The advantages of importing 0.75mm geomembrane from China are significant

1. In terms of product quality ,the production technology of Chinese manufacturers is mature, like Haoyang Environmental Co., LTD., the use of three layers of co-extrusion blowing film or double layer pressing process, strict quality control, products contain 97.5% high-density polyethylene and 2.5% anti-aging materials, good physical and mechanical properties, anti-permeability, anti-puncture, anti-aging performance is outstanding.

2. In terms of product specifications, the width can reach 1-8 meters, the length of 50 meters/roll, 100 meters/roll and other options, can also be customized according to customer needs, in line with the complex size and terrain of various types of fish ponds in Peru.

3. In terms of supply capacity, Haoyang Environmental Co., Ltd. can reach thousands of square meters per day, which can quickly respond to the needs of large-scale projects in Peru and ensure the construction period. And China's geomembrane is cost-effective, comprehensive quality and price, can help Peruvian customers reduce costs and improve project efficiency.

² Summarize

0.75mm geomembrane is of great significance for Peruvian fish ponds. It has excellent anti-seepage performance, can effectively avoid the waste of water resources caused by leakage, maintain a stable water level, and reduce the cost of water refill. Its good isolation can block the entry of harmful substances in the soil, improve water quality, and reduce the risk of disease of fish and shrimp. Moreover, the geomembrane is durable and anti-aging, can protect the fish pond slope, facilitate cleaning, reduce maintenance costs, and ultimately improve the economic efficiency and sustainability of the fishery.
