The rough geomembrane has excellent temperature adaptability, weldability, weather resistance and good aging resistance, chemical corrosion resistance, environmental stress cracking resistance and puncture resistance. Therefore, it is particularly suitable for underground works, mining works, landfills, sewage or waste treatment sites as anti-leakage materials. Rough surface geomembrane is a new type of anti-seepage material, single rough surface, double rough surface and other rough surface geomembrane increase friction coefficient, anti-slip function, more suitable for steep slope and vertical anti-seepage, improve engineering stability Rough surface geomembrane is a new type of anti-seepage material, single rough surface, double rough surface and other rough surface geomembrane increase friction coefficient, anti-slip function, more suitable for steep slope and vertical anti-seepage, improve engineering stability. Product series Single rough surface, double rough surface, column point non-slip, foot clamp. Rough geomembrane is an HDPE geomembrane with rough texture on the surface. Because of its unique rough texture, the rough surface geomembrane greatly strengthens the friction between the geomembrane and the geotextile, and can be easily and quickly applied to anti-seepage projects on steep slopes such as landfills and dam slope impermeability. At present, rough surface geomembrane is being used more and more widely in the engineering field. Its superior anti-slip performance has a very obvious effect on slope anti-slip and bottom geotextile slip and wrinkle prevention, which greatly facilitates construction, and solves the construction quality problem caused by smooth geomembrane sliding. However, some illegal manufacturers do not have the production capacity of rough geomembrane, and use recycled materials to destructively produce rough surfaces, causing a strong loss of 50% of the HDPE film. The elongation force is reduced by 5 times. The rough surface geomembrane, which is a regular process that cannot be used in the project, should have the same strength and elongation rate as the light mask, so that it can be used in the project. In addition to being widely used in the construction industry, anti-seepage geomembrane is also widely used in river dykes, reservoirs, channels, reservoirs, water diversion tunnels, highways, railways, tunnels, airports, water recreation facilities and various underground and underwater projects, and environmental protection projects such as landfills, sewage treatment plants, wastewater treatment plants, etc. With the rapid development of the national economy, the scope of use is expanding, and the demand for geomembrane is also increasing. There is reason to believe that geomembrane will play a huge role in the construction of the national economy and will also bring good economic and social benefits to related enterprises. Performance characteristics of impermeable geomembrane 1. High impermeability coefficient: HDPE impermeable geomembrane adopts high-density polyethylene native resin, which is made of co-extrusion technology, with high molecular density, extremely low liquid permeability, and anti-seepage effect unmatched by ordinary waterproof materials. 2. It has high tensile resistance: its excellent elasticity and deformation ability make it very suitable for expansion or contraction of the base surface, and can effectively overcome the uneven impermeable membrane settlement of the base surface, and the water vapor permeability coefficient K<=1.0*10- 13g.cm/ccm2.s.pa. 3. Chemical stability: The impermeable membrane has excellent chemical stability, high and low temperature resistance, asphalt, oil and tar, acid, alkali, salt and other chemical solutions. It is widely used in sewage treatment, chemical reaction tanks, landfills. High and low temperature resistance, asphalt, oil and tar resistance, corrosion resistance of more than 80 kinds of strong acid and alkali chemical media such as acid, alkali, salt, etc. 4. Aging resistance: impermeable membrane has excellent anti-aging, anti-ultraviolet, anti-decomposition ability, excellent tear resistance, puncture resistance, low brittleness, small thermal deformation, can be used exposed, and the service life of the material reaches 50-70 years, providing a good material guarantee for environmental impermeability. 2.5 Anti-plant root system: The impermeable membrane has excellent anti-puncture ability and can resist most plant root systems. 6. High mechanical strength: impermeable membrane has good mechanical strength, fracture tensile strength of 28MP, fracture elongation rate of 700%. 7. Low cost and high efficiency: the impermeable membrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and fast, so the product cost is lower than that of traditional waterproof materials. According to actual estimates, the general project using HDPE impermeable membrane saves about 50% of the cost. 8. Simple and convenient construction, fast speed, light weight, easy transportation: the impermeable membrane is light in weight, the finished product is in a roll shape, has high flexibility, and is easy to lay on site with high flexibility to meet the needs of different construction sites. There are a variety of specifications and laying forms to meet the anti-seepage requirements of different projects. Hot melt welding is adopted, the weld strength is high, and the construction is convenient, fast and healthy. 9. Environmental protection and non-toxicity: The materials used in the impermeable membrane are all non-toxic and environmentally friendly materials. The principle of anti-seepage is an ordinary physical change, does not produce any harmful substances, and is the choice of environmentally friendly, breeding and drinking pools. 10. Good welding effect: the impermeable membrane adopts a special welding machine, and the welding effect is very good. The strength of the weld is greater than the strength of the base material, and it is easy to construct
