Geomembrane useful life issues: Geomembrane selection of high quality virgin polyethylene resin, mainly composed of 97.5% high density polyethylene, about 2.5% of carbon black, anti-aging agents, antioxidants, UV absorbers and stabilizer materials, with the world's most advanced Italian automatic geotextile production equipment, the extrusion technology. All products are based on US GRI standards and ASTM testing standards, complete specifications. Geomembrane is polyethylene resin to add a certain proportion of carbon black masterbatch, anti-aging agents, antioxidants, UV absorbers, stabilizer blow molding, impermeable moisture for a new waterproof materials. High-density polyethylene geomembrane is a new custom-made EVA impermeable geomembrane, anti-corrosion material, is widely used among various impermeable corrosion requirements of the project. Geomembrane useful life of the issue of quality EVA geomembrane, mainly by impermeable impermeable plastic film is lost and given practical effect EVA geomembrane, EVA geomembrane according to national standards, with a thickness of 0.2m hydraulic plus stabilizer polyethylene film, water conditions in working life of up to 40 to 50 years, working in conditions of life under water 30 to 40 years. Therefore, the useful life of geomembrane sufficient to meet the requirements of the useful life of the dam seepage. Geomembrane is a substantially impermeable material. Depending on the raw materials can be divided into two major categories of polymer and bitumen. To meet the needs of different strength and deformation, there are not reinforced and reinforced the distinction. Polymer film manufacturing plant, bitumen membranes are mostly in the field of manufacturing. Polymers are thermoplastics manufactured geomembrane (e.g. polyvinyl chloride), crystalline thermoplastic plastic (e.g. high density polyethylene), thermoplastic elastomers (e.g., chlorinated polyethylene) and rubber (e.g. neoprene) and the like. Methods of manufacturing plants mainly geomembrane extrusion, calendering or add paint. The molten polymer is extruded through a die made geomembrane, a thickness of 0.25 ~ 4mm. Calendered thermoplastic polymer sucked by hot rolling into a geomembrane, a thickness of 0.25 ~ 2mm. The polymer was added to the paint is evenly coated paper on-chip, to be peeled off after cooling geomembrane made. Geomembrane manufacturing site is sprayed or deposited layer of cold or hot viscous polymer is made on the ground. Bituminous geomembrane using polymer bitumen or synthetic rubber. Manufacturing geomembrane also needed a certain amount of additives incorporated, so that without changing the basic properties of the material of the case, to improve some of its properties and cost. Such as the incorporation of carbon black can improve the ability of UV light anti-Japanese, anti-aging; doped lead salts, barium, calcium and derivatives to enhance thermal material, anti light stability; lubricants such as talc doped material to improve operability ; incorporation of fungicide to prevent bacterial destruction. For bituminous geomembrane, the main material is doped with some filler or fibers. Filler may be as fine mineral powder, it can increase the strength of the film and reduce its cost; the addition of fiber, but also to improve the strength of the film.
