Many ponds are used for fish breeding or aquatic plant planting. Geomembranes can help control water leakage, maintain pond water level stability, provide good water quality conditions for breeding and planting, and improve breeding efficiency. At present, there are aquatic product breeding bases using geomembranes as liners specifically for saline-alkali soils in Xinjiang and Weifang in our province. In the future, geomembranes will be greatly used in aquaculture, because the continuous discharge of Japan's nuclear-contaminated water into the sea will make seafood inedible, so artificially cultured aquatic products will greatly adapt to market demand. Geomembranes Being the best geotechnical product for pond lining will become a huge demand in the future.
Aquaculture Pond Liner Selection
The first key element in the construction of aquaculture ponds is anti-seepage. The best liner for anti-seepage is geomembrane. The pond liner produced by Haoyang Company is the best choice to use geomembrane, which can save a lot of trouble in later repairs. . Haoyang Company has HDPE double-sided smooth geomembrane and geotextile geomembrane composite products.
1. Advantages and disadvantages of a single HDPE geomembrane:
This kind of geomembrane has anti-ultraviolet, anti-oxidation, and anti-aging effects; the foundation of the pond needs to be very solid and completely free of hard objects, because hard objects will scratch the geomembrane and cause water leakage, even if it can be repaired Damage can also be very troublesome. We recommend laying a layer of geotextile under the geomembrane, which can effectively eliminate the risk of undiscovered hard objects scratching the geomembrane.
2. Advantages and disadvantages of composite geomembrane:
The advantage of composite geomembrane is that a layer of geotextile is compounded under the geomembrane, so that the geomembrane is protected from being scratched by hard or sharp objects in the soil layer and causing water leakage. The disadvantage is that the laying and transportation of composite geomembranes is more troublesome than single geomembranes, but this is not a key factor. And the price is almost the same as the combined price of a single geotextile and geomembrane. It is a good choice to enhance safety without much change in cost.
3. Parameter selection of aquaculture geomembrane liner:
3.1 Thickness and laying: The thickness of aquaculture geomembrane liners ranges from 0.2mm to 3.0mm, but remember that if a geomembrane with a thickness less than 1mm is used as a liner, a geotextile must be laid under the geomembrane. Either use a composite geomembrane as the base, and a layer of geotextile above or below the geomembrane. Otherwise, the geomembrane may be damaged over time due to pressure and extension force. Geomembranes with a thickness of more than 1mm can be used alone, and the base must be solid, flat and free of hard objects. Do not pull it up too tightly during laying. If it is pulled up too tightly, the pressure and extension force will increase after water injection and it will easily cause the purchase to break.
3.2 Width: The general width is 6 meters, 7 meters, and 10 meters. It can be cut according to the specific width requirements.
3.3 Length: Generally, the length of a roll is 50 meters or 100 meters, which can be cut according to your specific needs.
3.4 Temperature: Applicable unread range -70°C~110°C
Summarize:
Haoyang Company's geomembrane production adapts to the specific requirements of the market and can solve many practical application problems for customers. Aquaculture geomembrane liner is our current main product, with rich R&D and production experience.
According to the analysis of some authoritative departments, aquaculture geomembrane liners may be the future development direction of geomembranes and are a necessary product for many artificial ponds, artificial lakes and artificial dams.
