Four elements of 0.5mm fish pond anti-seepage membrane construction
First, the treatment of several sides of the anti-seepage membrane for 0.5mm fish pond cultivation. After the fish pond is dug, there should be no sharp stones at the bottom of the pond. If there are stones that are not easy to deal with, it is necessary to lay more than 200 grams geotextiles, isolation foundations and geomembranes. , can effectively protect the geomembrane. Filament geotextiles are recommended to use hot asphalt adhesive sleeves, and the oil temperature should be kept between 150~170°C.
Second, the thickness of the 0.5 anti-seepage membrane for fish pond cultivation is selected according to the type of cultivation. Ordinary fish can choose a geomembrane of 0.3 to 0.5 mm. Fish such as lobster and soft-shelled turtle need a membrane of 0.8 mm, so that it is not easy to be scratched. break. At the same time, the two have good corrosion resistance to bacteria and chemical effects, are not afraid of acid, alkali, and salt erosion, and have a longer service life when used in the dark.
Third, if the 0.5 fish pond culture impermeable membrane wants to be waterproof and durable, the construction quality is the key step. The overlapping width of the welding seam should be uniform and moderate, without slip welding and skip welding. In addition, attention should be paid to the protection of finished products during construction. Do not step on the constructed membrane at will, cover it well to avoid being blown by the wind. 0.5mm anti-seepage membrane for fish pond cultivation has high tensile strength, which enables the impermeable membrane of the reservoir to be used under harsh geological and climatic conditions, and has strong strain resistance in the case of uneven geological settlement, meeting high standards engineering needs.
The fourth is the most important. The 0.5mm fish pond anti-seepage membrane must do a good job in the maintenance of the slope in the later stage. In fact, the leakage of geomembrane in the later stage is due to careless protection during use. Any bumps will definitely affect its surface and affect its service life. It has good anti-aging and anti-ultraviolet performance in harsh natural environments, can be used exposed for a long time, is not easy to be decomposed and maintains its original performance.
