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.
Geomembrane packaging and transportation treatment
1. Products are usually packaged with PE film or woven fabric for outer packaging and tied with straps. The packaging size and container capacity of the product are different from the product specifications.
Also, we can follow up on customer on-site requirements and exchange them.
2. Container transportation, according to your project request.
