Basic Joint Lapping of Impermeable Geomembrane of Fish Pond

Fish pond impermeable membrane is a typical geomembrane product used in the construction of fish pond and shrimp pond. Its scope of use is also relatively wide, the use of skills is also widely concerned. As a geotechnical material manufacturer for many years, our company naturally understands the basic requirements for the impervious membrane joint lap of the fish pond, and I will take you for a simple understanding.

1. The joint treatment of fish pond impervious film is a key procedure of construction, which directly affects the service life of the project. According to the quality inspection, the hot welding method is ideal. (can also be bonded with a special adhesive) thermal welding method is the surface heating treatment of PE geomembrane connection, so that the surface is melted, and then fused into one through pressure.

2. The impermeable membrane of the fish pond should be laid in a certain direction, and the direction of each unit geomembrane should be adjusted when laying, so that the welding of the two units of geomembrane is easy.

3. After the fish pond impermeable film is laid, the sand bag should be pressed tightly to prevent wind movement. Edge joints should be free of dirt, moisture and dust.

4. Before the fish pond impermeable film welding, adjust the single film on both sides of the joint so that it overlaps a certain broadband, flat without wrinkles.

5. When welding the impervious film of the fish pond, an experienced technician shall be arranged for welding and a special welding machine shall be used for welding. Adjust temperature and speed. After years of practice has proved that the thickness of the geomembrane is not less than 0.25 mm, too thin may produce pores, easy to damage during the construction process, reduce the anti-seepage effect. In the construction of geomembrane, special attention should be paid to the laying not too tight, not wrinkled, and the splicing should be firm.

The surface lubrication of the impervious film of the fish pond can be useful in the rainy season to avoid the escape of fish, and its main function is to avoid the direct contact of fish with the soil and avoid water pollution. Fish pond impermeable membrane can not only prevent waste from accumulating in the soil, but also prevent harmful chemicals from entering the pond, which can reduce the risk of disease, useful maintenance and promote the growth of fish. The impermeable membrane of the fish pond can provide a smooth surface to the pond and easily remove the waste in the pond, which is easy to catch, and can also maintain the pond slope from corrosion. The standard of impermeable fish pond film: the standard of anti-aging fish pond film is generally 6 meters wide, and the thickness can be roughly divided into 0.3mm-1.0mm. Generally 0.75mm can be used, of course, the thicker the quality is better, the longer the service life. After using the impervious membrane of the fish pond, there will be no weeds, sludge and other things at the bottom of the pond that affect the speed of fishing, so it can be captured more efficiently. The time of capture will be greatly reduced, and the vitality and freshness of fish and shrimp will be greatly enhanced; The environmental adaptability of bacteria under the maintenance of impermeable membrane will be greatly reduced, and then the healthy growth of fish and shrimp will be eradicated or the possibility of disease transmission will be reduced, and the output value of fish and shrimp feeding will be improved. Because a lot of time is saved, and then the feeding cycle of the fish pond is accelerated, the output value is increased in disguise.

The above is the basic joint and lapping requirements of the fish pond impervious film, hoping to help customers better understand the fish pond impervious film, improve the quality of engineering construction, ensure the efficiency of aquaculture to provide support and help, more fish pond impervious film and other geomaterials products purchase, as well as knowledge details, you can pay more attention to my company website update.
