China Manufacturer HDPE Geomembrane Liners in Shrimp Farming

Product Description

Shrimp pond

Intensive commercial shrimp farming began in the late 1960S led in part by technological advances and growing market demand. Today, Shrimp farming is so intensive(in some case close to 300000 shrimp per hectare) that it requires industrially prepared shrimp feeds, fertilizing the pings to stimulate the growth of organisms, aeration to prevent oxygen depletion and regular tidal water exchange. HDPE geomembranes have been used in some of the largest shrimp pond projects in the world. There are several key benefits of lining shrimp ponds with geomembranes. Durable and robust, the HDPE surface prevents weeds, grasses, mud and other obstructive contaminants from entering the pond. The HDPE substrate is known to reduce the suitability of the environment for bacteria thereby reducing the need for antibiotics. Geomembranes can also protect the slopes and banks from erosion and allow for easy detection and repid removal of sediment and waste products.

Here are several factors to consider when deciding which type of geomembrane to use in a Shrimp Pond application

1.Stress crack resistance

2.Tensile and elongation properties

3.Tear and puncture resistance

4.Duration of the project

5.U.V exposure

Our smooth geomembrane is made of premium virgin HDPE resin designed specifically for geomembrane production along with adequate carbon black, antioxidant, and stabilizers to have superior mechanical properties and outstanding long-term resistance to chemical, ozone, oxidation, environmental stress crack, and UV radiation. These advantages make our geomembrane the most suitable for those exposed or non-exposed applications.

Performance:
 
1, Excellent physical and mechanical performance, high tearing resistance;good deformation adaptability, high puncture resistance;
2, High aging resistance, high UV resistance, anti-acid & alkali;
3, Excellent low & high temperature resistance, innocuous, long life span;
4, Perfect water proof performance, seepage and humidity resistance.
 
Application:

1,Prevent leakage disposal in landfill or waste water or waste dregs disposing field.
2,River bank, lake dam, mine remainings, reservoir, tunnel. Liquid storage pool(pit, mine)
3,Preventing leakage in subway, basement, tunnel, hole. Anti-salt leskage in roadbed and other groundsill.
4,The plane direction laying of dam, the vertical direction laying for groundsill, used in the construction fence and waste material field.
5,Used in seawater of freshwater feed field.
6,Used in groundsill of road, highway, railway and waterproof layer of swelling clay and wet collapsed loess.
7,Preventing leakage on rooftop
