Tianjin Hongchen Engineering Materials Co., Ltd. specializes in producing HDPE Yancheng aquaculture special geomembranes, anti-seepage Yancheng aquaculture special geomembranes, and HDPE anti-seepage membranes. It is a member of the China Environmental Protection Association and one of the manufacturers of HDPE Yancheng aquaculture special geomembranes in China. From 2009 to 2015, it undertook 40 large landfill anti-seepage projects in Liaoning, Jilin, Heilongjiang, and Inner Mongolia. For landfill anti-seepage projects, choose a strong enterprise like Tianjin Hongchen. The performance characteristics of the HDPE Yancheng aquaculture special geomembrane for landfill closure and anti-seepage are as follows: 1. The HDPE Yancheng aquaculture special geomembrane is a flexible waterproof material with a very high anti-seepage coefficient (1×10⁻¹⁷ cm/s); 2. The HDPE Yancheng aquaculture special geomembrane has good heat resistance and cold resistance, with a temperature range of use from high temperature 110°C to low temperature -70°C; 3. The HDPE Yancheng aquaculture special geomembrane has excellent chemical stability, resistant to strong acids, alkalis, and oils, making it a good anti-corrosion material; 4. The HDPE Yancheng aquaculture special geomembrane has high tensile strength, meeting the needs of high-standard engineering projects; 5. The HDPE Yancheng aquaculture special geomembrane has strong weather resistance and excellent aging resistance, allowing it to maintain its original performance even when exposed for long periods; 6. The HDPE Yancheng aquaculture special geomembrane uses three separate feeders, with different formulations in each layer to provide unique properties, enhancing the engineering performance of the HDPE Yancheng aquaculture special geomembrane; 7. The overall performance of the HDPE Yancheng aquaculture special geomembrane, with strong tensile strength and elongation at break, allows it to be used in various harsh geological and climatic conditions; 8. The HDPE Yancheng aquaculture special geomembrane is made from virgin plastic and carbon black particles, containing no preservatives. 4.5.1 The geocomposite drainage nets used in anti-seepage system projects should meet the following requirements: 1. The geogrid and geotextile in the geocomposite drainage net should be pre-bonded, and the bonding strength should be greater than 0.17kN/m; 2. The geogrid in the geocomposite drainage net should preferably be made of HDPE, with a longitudinal tensile strength greater than 8kN/m and a transverse tensile strength greater than 3kN/m; 3. The geotextile in the geocomposite drainage net should meet the requirements of Section 4.3 of this specification; 4. The drainage rate of the geocomposite drainage net should consider factors such as creep reduction, geotextile embedment reduction, biological clogging reduction, chemical clogging reduction, and chemical precipitation reduction. 4.5.2 The performance indicators of the geocomposite drainage net should meet the requirements of the current relevant national standards.
