HDPE Impermeable geomembrane is a waterproof barrier material based on high molecular polymer. The smooth geomembrane is made of high-quality raw material high-density polyethylene (HDPE) as the anti-seepage substrate, and a certain amount of carbon black, antioxidant, anti-aging agent, ultraviolet absorber and color masterbatch are added in a special formula during the production process Other auxiliary materials are refined by three-layer co-extrusion blow molding technology in batches using highly automated geomembrane equipment. As a professional geomembrane manufacturer, BPM brand smooth anti-seepage HDPE Impermeable geomembrane has ultraviolet radiation resistance, good flexibility, flexibility, elasticity, weather resistance, environmental stress cracking resistance, excellent chemical corrosion resistance and adhesion It can be used in a large temperature range and a long service life, and its mechanical indicators are higher than ordinary polyethylene. It is widely used in fish and shrimp farms, artificial lakes, landfills, tailings storage sites, Canal seepage control, dam seepage control, energy engineering and industrial waterproofing, tunnels, air-raid shelters, subway projects, etc. All the anti-seepage geomembrane products are produced according to national standards and American GRI standards.
Peru is rich in mining resources, one of the 12 largest mining countries in the world, with the total amount of minerals ranking seventh in the world. Tailings pond is an indispensable facility in mine production, and tailings pond is the largest environmental protection project of mining enterprises. It can prevent tailings from being discharged to rivers, lakes, sea deserts and grasslands at will. As long as tailings are produced in a concentrator of a mine, a tailings pond must be built. As a place for storing metal mines for ore separation and discharging tailings or other industrial waste residues, the annual output of Peru’s tailings is about 300 million tons, accounting for a quarter of the annual output of general industrial solid waste.
In recent years, due to the overexploitation of mineral resources, tailings leakage accidents have continued to occur. The existence of a large number of tailings ponds has posed a great potential pollution hazard to the surrounding ecological environment and water resources. Therefore, the leakage pollution of tailings ponds has been increasingly valued by the local government. Tailings are easy to flow and collapse during stockpiling, resulting in vegetation damage and injury accidents, especially in the rainy season. The dam body of tailings pond is relatively high, and there are unsafe hidden dangers.
The composition of tailings and residual beneficiation agents have seriously damaged the ecological environment, especially the tailings containing heavy metals, in which the sulfide produces acidic water to further leach heavy metals, and its loss will cause harm to the entire ecological environment.
Copper ore is brittle, and a large number of fine-grained copper ores and copper slimes will be produced during the grinding process. These fine-grained copper minerals and tin slimes will become tailings slag and be discharged into the tailings pond for storage due to the limitation of recovery technology. The stored tailings will not only waste resources but also pollute the environment. As the main part of the anti-seepage system, the copper tailings anti-seepage membrane is used to reduce the impact of mining on the environment. BPM copper tailings anti-seepage membrane is used for various mineral tailings projects, such as heap leaching pond, evaporation pond, brine pond and tailings dam.
The La Paz copper mine in Peru is located in the Peruvian plateau, with an average altitude of 4000m. The project is in the extreme conditions of high cold and hypoxia, and there are often continuous rainy and snowy weather. In addition, the local ultraviolet radiation intensity is high all year round, the construction operation is difficult, the conditions are bad, and the environment is difficult
Due to the harsh natural environment and construction environment of the project, the construction period is tight and the construction is difficult, and the anti-seepage project is the key link to ensure the success of the project. The project needs to use a large number of high-quality HDPE geomembrane materials. On the one hand, it can be more safely applied to the working environment with high altitude and strong ultraviolet radiation; On the other hand, this project is a key construction project of Peru’s mining industry. It is very important to select geomembrane products with reliable product quality, sufficient production capacity and timely supply.
The copper tailings anti-seepage HDPE Impermeable geomembrane is produced by three-layer co extrusion blow molding process with a certain proportion of carbon black matrix added with polyethylene resin (the main component is 97.5% high-density polyethylene) and other anti oxidants (anti-aging agent, antioxidant, ultraviolet absorber, stabilizer). The copper tailings anti-seepage HDPE Impermeable geomembrane is a new type of anti-seepage and anti-corrosion material. The product quality is selected from the American ASTM inspection standard, which can meet the requirements of the American GRI-GM13 standard.
During the epidemic, the customer was unable to arrive in China. Through the third-party testing company, the customer made a detailed understanding and record of our factory’s supporting facilities, geomembrane production process, product quality, appearance, thickness, source of raw materials, and product formula. Subsequently, the two sides confirmed that the sub-mine project has an area of 500000 square meters through multiple rounds of video conference. The procurement of smooth geomembrane 2.0mm and double rough geomembrane 2.0mm totaled 750000 square meters.
The geomembrane of tailings dam has excellent chemical stability, and is widely used in sewage treatment, chemical reaction tank and landfill. It is resistant to high and low temperature, asphalt, oil and tar, and more than 80 kinds of strong acid and alkali chemical media such as acid, alkali and salt.
