Tianjin Hongchen Engineering Materials Co., Ltd. specializes in producing HDPE Lianyungang aquaculture special geomembranes, anti-seepage Lianyungang aquaculture special geomembranes, and HDPE anti-seepage membranes. It is a member unit of China Environmental Protection and one of the manufacturers of HDPE Lianyungang aquaculture special geomembranes in China. From 2009 to 2015, it undertook anti-seepage projects for forty large landfills in Liaoning, Jilin, Heilongjiang, and Inner Mongolia. When selecting a company for landfill anti-seepage projects, choose a strong enterprise like Tianjin Hongchen. The performance characteristics of HDPE Lianyungang aquaculture special geomembrane for landfill capping and anti-seepage are as follows: 1. HDPE Lianyungang aquaculture special geomembrane is a flexible waterproof material with a very high anti-seepage coefficient (1×10⁻¹⁷ cm/s); 2. HDPE Lianyungang aquaculture special geomembrane has good heat resistance and cold resistance, with a usage temperature range of high temperature 110℃ and low temperature -70℃; 3. HDPE Lianyungang aquaculture special geomembrane has excellent chemical stability, resisting strong acids, alkalis, and oils, making it a good anti-corrosion material; 4. HDPE Lianyungang aquaculture special geomembrane has high tensile strength, meeting the requirements of high-standard engineering projects; 5. HDPE Lianyungang aquaculture special geomembrane has strong weather resistance and aging resistance, maintaining its original performance even after prolonged exposure; 6. HDPE Lianyungang aquaculture special geomembrane uses three separate feeders, allowing for unique properties from different formulations in each layer, enhancing the engineering performance of the HDPE Lianyungang aquaculture special geomembrane; 7. The overall performance of HDPE Lianyungang aquaculture special geomembrane has strong tensile strength and elongation at break, allowing it to be used under various harsh geological and climatic conditions; 8. HDPE Lianyungang aquaculture special geomembrane is made of virgin plastic and carbon black particles without any preservatives. 4.5.1 The geocomposite drainage network used in anti-seepage system projects should meet the following requirements: 1. The geonet and geotextile in the geocomposite drainage network should be pre-bonded, and the bonding strength should be greater than 0.17kN/m; 2. The geonet of the geocomposite drainage network should preferably use HDPE material, with a longitudinal tensile strength greater than 8kN/m and a transverse tensile strength greater than 3kN/m; 3. The geotextile of the geocomposite drainage network should meet the requirements of Section 4.3 of this specification; 4. The water conductivity selection of the geocomposite drainage network should consider factors such as creep reduction, geotextile embedding reduction, biological clogging reduction, chemical clogging reduction, and chemical precipitation reduction. 4.5.2 The performance indicators of the geocomposite drainage network should comply with the requirements of the current relevant national standards.
