Geomembrane is usually divided into HDPE smooth surface geomembrane and HDPE textured surface geomembrane according to the surface. Their main components are composed of 97.5% high-density polyethylene and 2.5% carbon black. The main function of carbon black is anti-aging and anti-oxidation. and UV resistance. The difference between HDPE smooth surface geomembrane and ane is usually divided into HDPE smooth surface geomembrane and masks is that they have densely textured spots on their surfaces, only one side with textured spots is called single textured geomembrane, those with textured spots on both sides are called double textured geomembrane, and those without textured spots are smooth geomembrane.
Textured surface HDPE geomembrane liner has excellent temperature adaptability, weldability, weather resistance, good aging resistance, chemical resistance, environmental stress crack resistance, and puncture resistance. Textured surface HDPE geomembrane liner is a new type of anti-seepage material. HDPE geomembranes liner such as single textured surface and double textured surface increase the friction coefficient and anti-skid function, which are more suitable for steep slope and vertical anti-seepage, and improve engineering stability.
Single textured surface geomembrane: single textured surface geomembrane is a geomembrane with one textured side and one smooth side. In the construction of slope anti-seepage engineering, the textured side of the single textured surface geomembrane is often in contact with the geotextile so as to play a non-slip effect.
Double-textured geomembrane: Double-textured geomembrane is a geomembrane with textured surfaces on both sides. Double-textured geomembrane is widely used. A double-textured geomembrane can be in contact with geotextiles on both sides in the construction of slope anti-seepage projects. Anti-slip effect.
Pillar point geomembrane: A pillar point geomembrane is a geomembrane with uniform raised points on one or both sides. The textured points of the pillar point geomembrane are evenly distributed and beautiful. Column-point geomembrane can also be used in slope anti-seepage projects to achieve anti-seepage, anti-skid, and anti-fouling effects.
The textured geomembrane is mainly used in the slope anti-skid and seepage prevention and closure of some daily garbage landfills, tailings ponds, and other projects; while the smooth geomembrane is used in the bottom of the landfill, artificial lakes, reservoirs, and other projects in the impermeable body. textured geomembrane has a better elongation at break and resistance to environmental stress cracking and better environmental adaptability than glossy geomembrane.
