Everyone said that HDPE anti-seepage geomembrane is mainly used as chemical sewage pond, landfill, fish pond, etc. The anti-seepage geomembrane mainly includes polyvinyl chloride (PVC), polyethylene (PE) and EVA. They are a class of polymer chemically flexible materials with small specific gravity, strong extensibility, high adaptability to deformation, high corrosion resistance Low temperature resistance and good frost resistance.
The standard name of the anti-seepage geomembrane is polyethylene anti-seepage geomembrane, which is mainly produced from the milky white translucent to opaque thermoplastic resin material-polyethylene resin. Polyethylene is a type of high-molecular polymer, white particles that are non-toxic, odorless, and odorless. The impermeable membrane has excellent heat resistance and cold resistance. It has good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tearing. With the increase of density, physical properties and barrier properties will be correspondingly improved. High; resistant to acid, alkali and organic solvents. The results show that HDPE film has excellent adaptability and aging resistance.
What specific measures can be used to slow down the aging of HDPE waterproof film? The anti-aging effect can also be achieved from two levels: one is to add anti-aging agents to the original art and technology to suppress external factors such as light, oxygen, and heat Effect. For example, add appropriate amounts of antioxidants, light stabilizers and carbon black, and at the same time choose safety measures during the project period, such as reducing the exposure of arts and crafts to the sun, choose rocks and soil (30 cm thick) or deep water shrine. Excellent filtration and drainage applications: Polyethylene impermeable membranes can be used not only for large-scale water conservancy projects, but also for everyone's business. For example, the filter in everyone's pure water dispenser is made of advanced HDPE impermeable membrane products. (This article is published by geotextiles; this text is for reference only. In the application of high-density polyethylene anti-seepage geomembrane as water, generally use high-density polyethylene anti-seepage geomembrane to filter clean water.
In addition, which kind of HDPE anti-seepage geomembrane has excellent drainage function, it is best to turn it into every excellent drainage pipe, and then help the soil layer secrete excess water and atmosphere. In addition, HDPE impervious geomembrane has a very good maintenance effect on the soil layer. When a flood occurs, it can collect and use energy, secrete excess water, and ensure the stability of the soil layer.
