Two cloth one film where the good? Election the Thai An Yongli geotextile material Ltd., supply the country Contact: * Li * Phone :182 - 6481 - 7103 QQ :46-37-96-887 (space with a variety of geotechnical materials, impermeable membrane picture) please call - plus Q-purchase, and look forward to your sincere cooperation! ! : Two cloth one membrane material mechanism of two cloth one film is a plastic film as an impermeable substrate, and non-woven geotextile made of impermeable material. Its performance depends on impermeable impermeable plastic film performance. The application of impermeable plastic film, polyvinyl chloride (PVC) and polyethylene (PE), which is a flexible material polymer chemistry, the proportion of small, strong extension, adapt to high deformation, corrosion-resistant, low temperature resistance, frost resistance. The thickness of the film is generally 0.30-2.00mm. The main mechanism of the impermeability of the plastic film cut off earth leakage channel, its greater tensile strength and elongation under pressure and adapt to dam deformation. And non-woven fiber is a polymer chemical materials, through needle stick or hot forming, high tensile strength and elongation. Applied to the composite non-woven fabric: polyester staple fiber needle-punched geotextile, Polyester filament spunbonded geotextile fabric, flat woven cloth. Combined with plastic film, not only increases the tensile strength and puncture resistance of plastic film, woven surface roughness increases the contact surface coefficient of friction, help protect the geomembrane layer stability. The same time, they are good bacteria and chemical erosion resistance, not afraid of acid, alkali, salt erosion. : Two cloth one membrane construction requirements geotextile as a protective layer of geomembrane, impermeable layer of protection from damage. In order to reduce the ultraviolet radiation to increase the anti-aging properties, the best laid by laying method. Construction, the first use of material smaller diameter leveling sand or clay base surface, and then laying laying will not be stretched too tightly, both ends of the buried soil corrugated section, and finally in the shop cloth film over-layer of fine sand or clay layer about 10cm. Lined with stone (20-30cm or precast concrete blocks), anti-scour protection layer. Construction, every effort should be made to avoid the stones hit directly on the best side to side laying the construction of the protective layer. Two cloth one membrane surrounding structures connection should be used to anchor bolts and steel layering, the joints brushing emulsified asphalt (2mm) thick adhesive to prevent leakage. The construction seams processing is a key processes directly affect the anti-seepage effect. General seams ways: (1) lap: lap width should be greater than 15 cm; (2) heat welding: appropriate for thicker geomembrane base material, weld lap width of not less than 5CM (not recommended glued a long time immersed in water easy to open plastic, anti-seepage effect). : Two cloth one membrane application range of environmental sanitation projects (such as municipal solid waste landfill, sewage treatment plants, toxic and hazardous material disposal sites, dangerous goods warehouse, plant) Water Conservancy and Civil Engineering (river \ lake \ res \ dam seepage plugging, reinforcement, drainage of seepage, vertical heart wall, slope protection, etc.) Municipal Engineering (subway, underground buildings and roof cisterns, roof garden seepage, sewage pipe lining, etc.) Landscaping (artificial lake , ponds, golf course pond underlay, slope protection, etc.) petrochemical (chemical plants, the refinery oil reservoir seepage pollution, chemical reaction tanks, sedimentation tank lining and secondary lining) Mining (washing pool, heap leaching pool, ash-field of tailings dam seepage pollution) transport infrastructure projects (road base reinforcement, culverts impermeable) agriculture (reservoirs, water tanks, water storage pond, irrigation systems, the seepage) aquatic aquaculture (fish ponds, shrimp ponds lined).
