Popular science knowledge about geomembrane

Generally speaking, geomembrane is a kind of plastic film, with specifications ranging from 0.2 mm to 3.0 mm thick, and 1.0 to 3.0 mm workshops are customarily called plates, also called waterproof plates, which have the characteristics of anti-seepage and isolation. Geomembranes are classified into corporate standards, national standards, new materials, urban construction, and American standards according to their quality. Due to the excellent anti-seepage performance of geomembrane, hdpe anti-seepage geomembrane is widely used in landfills, mining ash yards, waste residue treatment plants, reservoirs, municipalities, highways, fish ponds, biogas tanks, tailings reservoirs, reservoirs, and artificial Environmental protection and seepage prevention projects such as lakes are in progress.

Many membranes can be seen in daily life. The geotextile uses plastic film as the impermeable base material, and the non-fabric composite geotextile material is a red impermeable material. Generally, plastic film and fiber film are more common. Agricultural vegetable greenhouses use plastic films, and the anti-seepage performance of the new material geomembrane mainly depends on the anti-seepage performance of the plastic film. At present, the plastic films used for anti-seepage at home and abroad are mainly polyvinyl chloride and polyethylene, so what is the role of geomembrane? This should be of concern to everyone. Let me introduce to you in a small series. What is the role of geomembrane? The characteristics of the geomembrane are as follows: 1. It is a flexible waterproof material with a high impermeability coefficient (110-17cm/s); 2. It has good heat resistance and cold resistance, and the working environment temperature is 110 at high temperature and -70 at low temperature; 3 .It has good chemical stability, can resist the corrosion of strong acid, strong alkali and oil, and is a good anti-corrosion material; 4. It has high tensile strength, so that it has high tensile strength and can meet The needs of high-standard engineering projects; 5. It has strong weather resistance and strong anti-aging performance, which can be used for a long time and maintain the original performance; 6. Good overall performance, strong tensile strength and elongation at break , So that it can be used in a variety of harsh geological and climatic conditions. Strong adaptability to uneven geological settlement! 7. The original plastic and carbon black particles do not contain any preservatives. High-density polyethylene has replaced polyvinyl chloride as the raw material for food packaging bags and cling film in China. What is the role of geomembrane? Application of geomembrane: anti-seepage in landfills, sewage or waste residue treatment plants. River embankments, lake dams, tailings dams, sewage dams, reservoir areas, river courses and liquid storage tanks. Anti-seepage lining of subways, basements, tunnels and tunnels. Salt water leakage control of roadbed and other foundations. Horizontal anti-seepage blanket in front of dike and dam, vertical anti-seepage layer of foundation, construction cofferdam, spoil yard.

Sea water and fresh water farms. Foundation of highways, highways and railways; waterproof layer of expansive soil and collapsible loess. The roof is impervious. This is a detailed introduction to the functions of geomembrane. I believe everyone knows what the geomembrane has after reading it. There are many places where geomembrane is used in life. It is very important to understand that geomembrane is suitable for environmental protection and sanitation, such as landfills, sewage treatment plants, power plant regulating ponds, industrial and hospital solid wastes, etc. Waterproof membranes are used in water conservancy projects, channel seepage prevention, etc. It has a great effect, so if you want to make better use of geomembrane.
