Plastic pond liner, also known as geomembrane pond liner or HDPE pond liner, is the ideal impermeable geotechnical product for the lining system of waste water treatment project. The discharge of industrial wastewater is one of the main sources of water pollution in modern society. In order to reduce the direct discharge of wastewater and control the pollution of water resources, the Pakistani government requires manufacturing factories to build sewage treatment ponds to treat wastewater harmlessly. At present, the traditional sewage treatment ponds usually adopt reinforced concrete and soil ponds, but these structures have some defects, such as high cost, complex construction technology, long construction period and easy cracking, especially when applied to some large-volume ponds (such as regulating pond and aeration pond), these defects are more prominent. At the same time, the anti-seepage performance of the soil pool structure is poor. The water of the sewage pool mainly contains acid and alkaline, toxic and harmful substances, which will produce temperature changes in the process of water treatment, so the requirements for the anti-seepage of HDPE geomembrane liner for the pool are relatively high.
The Plastic Pond Liner has the following characteristics.
- High strength.
- Good acid and alkali resistant, corrosion resistant, it can resist more than 80 kinds of strong acid and alkali and other chemical media corrosion.
- Good impermeability, its water vapor permeability coefficient K <=1.0*10-13 g.cm/cm2.s.pa.
- Low temperature resistance, its cold brittle temperature-60 degrees to-70 degrees.
- High temperature resistance: its melting temperature 110 degrees to 120 degrees.
- Anti-rodent and microbial invasion, while avoiding the risk of leakage.
- Good ductility: good surface adaptability and weather resistance. Good anti-seepage ability: permeability coefficient is less than 1 *10-13 cm/s.
- Good chemical stability: HDPE softening point is about 121 C, cold embrittlement point is about – 120 C. It has strong resistance to inorganic acids, organic acids, inorganic salts, alcohols, aldehydes, amines, esters and oils. It can work in sewage environment for more than 50 years.
- It has good anti-ultraviolet aging property: the carbon black added in HDPE geomembrane formula has anti-ultraviolet ability.Resistance to rodent and microbial invasion: Various experiments have shown that animals and microorganisms only attack polymers containing plasticizers, while HDPE geomembrane is generally not affected by these organisms because of the absence of plasticizers.
Due to the above advantages, the HDPE geomembrane pond liner is suitable for various types of sewage tanks with simpler size. The Chinese government has advocated the “one belt and one way” foreign economic policy. The Pakistan government has great preferential policies to import plastic pond liner from China. Therefore, our Pakistan customers contacted us through our official website to order 15000 square meters of 1.5mm plastic pond liner requiring soot and trace amounts of 2.5% antioxidants and heat stabilizers to keep its designed quality.
