With economic development and social progress, environmental protection issues have received attention from everyone. Since it comes to environmental protection, it is inevitable that geotextiles, especially geotextile and geomembrane, are used. Now in daily life, this new material can be seen everywhere. The editor will tell you about the commonly used anti-seepage film for fish and shrimp farming and fish pond viewing projects around us. The anti-seepage membrane of fish ponds is one of the commonly used geotechnical materials for household fish farming, ornamental fish ponds, and small fish ponds.
The main reason for using this material is that the cost of anti-seepage geomembrane material is much lower than that of concrete; Secondly, due to the more convenient construction and simple transportation of anti-seepage membrane materials, it can effectively reduce the construction time and process. The use of impermeable membrane materials can directly drain water, landfill, and lay impermeable membranes, which will not damage the structure of the fish pond itself, saving time and effort, and is becoming increasingly popular. The editor believes that many people may have doubts about whether fish ponds made with this type of anti-seepage film will have an impact on fish? How long can fish live inside?
In fact, it is not difficult to answer this question. The anti-seepage membrane, also known as geotechnical membrane and high-density polyethylene membrane, is made of polyethylene, anti-aging agent, antioxidant, carbon black and other materials through special processes. These ingredients are harmless and will not have any impact on humans or animals. Therefore, fish ponds laid with impermeable membranes are relatively safe, as long as the laying is completed, water can be directly released for fish farming.
But in terms of selecting materials, it is also important to pay attention to cooperating with manufacturers to ensure quality. Since it is for fish farming, the requirements for the materials themselves are also very strict. It is necessary to select standardized materials. If the original materials are not used properly, it may not be possible to raise live fish. As the anti-seepage film of the new material specification is dedicated to aquaculture, if new materials are not used, the taste is relatively strong, and there is no benefit for aquaculture. The new anti-seepage membrane also has the advantage of long service life. Under normal weather conditions, there is no human damage, and the anti-seepage membrane in fish ponds can be used for about 10 years.
For fish ponds, the thickness of the anti-seepage film is not required to be too thick, usually between 0.4 and 0.7 millimeters. This thickness is relatively thin, and special attention should be paid during transportation and construction. So, to summarize, using anti-seepage membrane geotextile for fish farming is not a problem, but it is important to pay attention to the selection of geotextile materials and be sure to choose new anti-seepage membranes.
