As a type of water-repellent substrate, impermeable geomembrane can be seen in large and medium-sized national engineering projects that benefit the country and the people, farmers, oysters, fish, scorpions, mud and other common rural household environments. There is only one layer of plastic film on the car. So what should you pay attention to when buying anti-seepage geomembrane?
Because anti-seepage membrane manufacturers are uneven in the market, some anti-seepage membrane manufacturers are fake and inferior, which obviously disrupts the normal market order. Some customers are artificial, and the price of anti-seepage geomembrane is very high, which is also a type of prejudice. When selecting the anti-seepage geomembrane, the main consideration is the anti-seepage effect of the anti-seepage geomembrane. A good barrier film is not low.
The simple way is to look at the appearance of the anti-seepage geomembrane, such as the surface is smooth and free of particles, and usually judge whether the anti-seepage effect is excellent. This does not mean that the anti-seepage geomembrane with particles on the surface must have poor anti-seepage effect. This is only relatively speaking. The special anti-seepage effect of the anti-seepage geomembrane must be tested by professional test equipment to determine the anti-seepage effect.
In order to ensure the construction quality of the anti-seepage geomembrane, the appropriate width of the anti-seepage geomembrane should be selected according to the actual situation on the construction site to minimize the number of welded anti-seepage geomembrane. First, it can reduce the workload, and second, it has the anti-seepage effect of a layer of anti-seepage geomembrane.
The selection of anti-seepage geomembrane is based on existing research results. Consult the relevant manufacturers of anti-seepage geomembrane, if necessary, conduct corrosion resistance test of anti-seepage geomembrane, and determine the appropriate anti-seepage geomembrane through comparison test. In such cases, the corrosion resistance of the anti-seepage geomembrane itself should not be considered, and the chemical resistance of the bonded joint should be handled with care.
