Product Description

Product Description

HDPE Geomembrane, abbreviated as HDPE Geomembrane, is a geosynthetic material produced from high-density polyethylene resin through blow molding, coating and other processes. It has excellent chemical stability, corrosion resistance, weather resistance, mechanical strength, as well as good impermeability, and is widely used in fields such as landfill sites, tailings ponds, hydraulic engineering, and agricultural anti-seepage.

Application

Good anti-seepage performance:
HDPE geomembrane has extremely low water permeability, which can effectively prevent the infiltration of water, chemicals, and other particles, ensuring the safety and reliability of anti-seepage engineering.

Strong chemical stability:
HDPE geomembrane has excellent chemical stability and can resist the erosion of most chemical substances, including acids, alkalis, salts, etc.

Good weather resistance:
HDPE geomembrane can withstand ultraviolet radiation and temperature changes in the natural environment without significantly reducing its performance due to aging.

Safety:
HDPE geomembrane does not contain harmful substances and will not pose a threat to the environment and human health.

Puncture resistance:
HDPE geomembrane has good puncture resistance and can resist sharp objects that may occur during construction.

Joint stability:
The joints of HDPE geomembrane are treated with special techniques to ensure the anti-seepage performance at the joints.

Good weather resistance:
HDPE geomembrane can withstand ultraviolet radiation and temperature changes in the natural environment without significantly reducing its performance due to aging.

High mechanical strength:
HDPE geomembrane has good tensile strength and puncture resistance, and can adapt to various complex geological and environmental conditions.

Biological erosion resistance:
It has good resistance to the erosion of microorganisms and plants in the soil.

The origin of HDPE geomembrane can be traced back to the 1950s, when polyethylene materials began to be synthesized and used for various industrial applications. With the development of materials science and the increasing demand for civil engineering, polyethylene geomembrane began to be widely used in anti-seepage engineering in the 1970s. HDPE geomembrane has been widely used in construction projects such as landfills, sewage treatment facilities, reservoirs, channels, roads, and railway foundations due to its high density and uniform thickness, which can provide excellent waterproof and pollution prevention performance.

HDPE composite HDPE film is also known as high-density polyethylene film, HDPE geotextile film, HDPE anti-seepage film. HDPE film is a plastic roll material composed of HDPE, which is a high crystallinity, non-polar thermoplastic resin. The surface of the original HDPE is milky white, with a certain degree of translucency in the thin section. PE has excellent resistance to most household and industrial chemicals.

 

Detailed introduction

Production process of HDPE geomembrane

High density polyethylene (HDPE) geomembrane is a waterproof and anti-seepage material widely used in civil engineering, environmental protection, water conservancy, agriculture and other fields. The following is a detailed introduction to the blow molding production process of HDPE geomembrane:

Raw material preparation: Firstly, it is necessary to prepare high-density polyethylene particles, which are the main raw materials for producing HDPE geomembranes. HDPE particles shall have good thermal stability, aging resistance and puncture resistance.

Melt extrusion: High density polyethylene particles are heated and melted through a melt extruder to become a molten state of high-density polyethylene. Melt extruders typically include single screw extruders, twin screw extruders, and conical screw extruders. During the melting process, strict control of temperature, pressure, and screw speed is required to ensure the melting quality of high-density polyethylene.

Blow molding: Melted high-density polyethylene is blown into shape using a blow molding machine. Blow molding machines mainly include blow molding machines and blow molding machines. During the blow molding process, the melted high-density polyethylene is blown into a thin film shape through a blowing nozzle, and then the required thickness of HDPE geomembrane is produced through processes such as cooling, traction, and winding.

Welding: Weld the HDPE geomembrane to improve its anti-seepage performance. Welding methods include hot welding, ultrasonic welding, and electric fusion welding. When welding, it is necessary to ensure the firmness and sealing of the weld seam to prevent the penetration of moisture, chemicals, and other debris.

Testing and quality control: test various performance indexes of HDPE geomembrane produced, such as tensile strength, elongation at break, puncture resistance, aging resistance, etc. Ensure product quality meets national standards and customer requirements.

Packaging and storage: Pack the HDPE geomembrane that has passed the test and store it in a dry and ventilated warehouse to avoid exposure to sunlight, rain, and chemical corrosion.
