What is textured geomembrane?
textured geomembrane is a new type of engineering anti-seepage geosynthetics, generally using high-density polyethylene or polypropylene as raw materials, refined by specialized production equipment and special production process. textured geomembrane can be designed and manufactured into a single or double textured surface, called single textured, double textured geomembrane, textured geomembrane can greatly improve the coefficient of friction, to maximize the effective volume of geomembrane, more suitable for steep slope and vertical engineering seepage and enhancement, the edge is smooth, in order to achieve high quality hot melt welding.
The following is a detailed introduction of the textured geomembrane:
Material characteristics
Anti-seepage ability: textured geomembrane has excellent anti-seepage performance, its anti-seepage coefficient K is less than 1.010 ^ -13g · cm / ccm ² · s · pa, can effectively prevent water leakage into other areas through the isolation layer.
Durability: textured geomembrane is made of high density polyethylene, low density polyethylene and other materials, with good corrosion resistance, aging resistance, strong toughness and other characteristics, to ensure the durability of the service life of materials.
rough design: the surface of rough geomembrane has rough stone pattern, which can increase the area combined with the soil, enhance the adhesion between the foundation and the soil, and prevent the water in the soil from leaking through the isolation layer. At the same time, the textured design can also increase the friction coefficient and improve the stability of the slope.
Application advantage
Improve the seepage prevention effect: textured geomembrane slows down the penetration rate of groundwater through friction, so as to achieve better seepage prevention effect.
Infrastructure requirements are reduced: rough geomembrane can form a certain textured effect on the soil surface of the bottom of the reservoir, better attach the soil, avoid being washed or stripped by water, and reduce the requirements on the bottom of the reservoir infrastructure.
Long service life: rough geomembrane can effectively avoid the damage of the traditional geomembrane caused by the bottom of the conventional road, prolong the service life of geomembrane.
To sum up, the rough geomembrane has a wide application prospect in water conservancy, environmental protection, transportation and other fields with its excellent seepage performance, durability and rough design.

In short, the rough geomembrane, with its excellent seepage prevention performance and rough design characteristics, has a wide range of applications in water conservancy engineering, environmental protection engineering, traffic engineering, landscape, mining engineering, agriculture and many other fields.
Production engineering
Nitrogen foaming textured geomembrane: replace the foaming agent with nitrogen and directly mix with PE geomembrane raw materials, after mixing with the ordinary layer of PE geomembrane raw materials together into the multilayer coextrusion mold head of different flow channel, common extrusion molding. This method belongs to primary molding and is suitable for continuous production of blowing molding process.
Stagne geomembrane: PE particles are plasticized by the mold head, and formed by the press bar with regular concave surface.
Spray and coarse method: through the smooth surface surface coarse particles form textured of geomembrane, which is the only one without sacrificing the mechanical properties and structural integrity of the base film produced rough geomembrane coarse process, so to the greatest extent retained the physical and mechanical tensile properties.
Size of product
Thickness: The thickness of the textured geomembrane is usually between 1.0mm and 3.0mm, with the larger dosage of 1.5mm and 2.0mm. This thickness range ensures that the geomembrane has sufficient strength and durability to meet various engineering needs.
Width: the width of the textured geomembrane according to the production capacity and engineering requirements, generally can produce 1 meter to 10 meters wide, can be customized according to the construction environment and project requirements.
Length: The length of the textured geomembrane is usually customized according to the engineering design and customer requirements to meet the needs of specific projects.
Color: The textured geomembrane is usually black or white, and these colors help to absorb or reflect sunlight to meet the needs of different environments and uses.
Chemical resistance: the textured geomembrane has excellent chemical resistance, can resist the erosion of various chemical substances, so as to maintain its long-term stability and service life.
Anti-skid function: the surface of the textured geomembrane after special treatment, has a large friction coefficient, with good anti-skid function. This makes rough geomembrane especially suitable for steep slope and vertical seepage prevention engineering, can improve the stability and safety of engineering.
In conclusion, the product specifications of the textured geomembrane cover the thickness, width, length, color, and chemical resistance and anti-skid function. These specifications are designed to meet various engineering needs and ensure that the textured geomembrane can achieve good seepage protection and performance in various environments.
