The Product Description of Bentonite Geosynthetic Clay Liner

Bentonite Geosynthetic Clay Liner
Bentonite GCL

Bentonite Geosynthetic Clay Liner is a kind of geosynthetics used in artificial lake water, landfill, underground garage, roof garden, pool, oil depot and chemical yard. It is filled with high expansive sodium bentonite in a special compound geotextile and nonwoven fabric, and is made of prick method. The soil impervious mat can form a lot of small fiber space, so that the bentonite particles can not flow in one direction. In the case of water, a uniform high density rubber waterproof layer is formed in the cushion, which effectively prevents water leakage. The main mechanism of bentonite waterproof blanket is to separate the water leakage passage of the earth dam with the non permeable property of the plastic film, and bear the water pressure and adapt to the deformation of the dam with its larger tensile strength and elongation, and the non-woven fabric is also a kind of polymer short fiber chemical material, which has high tensile strength and extensibility by needle or hot sticky forming. The combination of plastic film and plastic film not only increases the tensile strength and anti puncture ability of the plastic film, but also increases the friction coefficient of the contact surface because of the roughness of the non-woven fabric, which is beneficial to the stability of the composite geomembrane and the protective layer. At the same time, they have good corrosion resistance to bacteria and chemical action, and are not afraid of corrosion of acids, alkalis and salts.
