How is Our Geomembrane Produced?
Geomembrane is formed through the extrusion production process, the specific steps are as follows:
↘ First of all, raw material preparation: according to the required characteristics of the geomembrane, select high-quality polymer resins, such as polyethylene (HDPE), etc. Different masterbatches can be added to harmonize the color of the geomembrane.
↘ Secondly, extrusion: the selected polymer resin is heated and melted in the extruder. The molten polymer is then pushed into the mold to form a continuous sheet or film.
↘ The third is calendering or rolling: the extruded sheet is pressed through a roller to smooth the material, ensuring uniform thickness and surface finish.
↘ The fourth is cooling and solidification: the flat sheet is cooled by cooling rollers or water baths. This rapid cooling process solidifies the polymer into a stable geodiaphragm.
↘ The fifth is testing and quality control: the geomembrane is inspected for quality and tested for parameters such as thickness, tensile strength, tear resistance and flexibility to ensure that it meets industry standards and specifications.
↘ The sixth is finishing: geomembrane can be processed through additional surface texturing or surface treatment processes to improve specific performance characteristics if required for certain applications. The geomembrane of Haoyang environment can make single or double rough surface.
↘ Finally, cutting and packaging: once the quality check is passed, the geomembrane is cut to the desired size, rolled into large scrolls or folded into specific sizes, packaged and shipped to the end user or stored. Haoyang environment has a complete testing center, each batch of products must go through strict testing before shipping.
The production of geomembranes involves precise control of temperature, pressure and quality checks throughout the manufacturing process to ensure consistency and compliance with standards.
Geomembrane Advantages and Applications
(1) The membrane has excellent waterproof and impermeable function, which can effectively isolate water, chemicals or pollutants from penetrating into the soil or structure. It can be used as a waterproof barrier for basements, tunnels, reservoirs, river embankments, water conservancy projects and other projects to effectively prevent water seepage and leakage.
(2) Geomembranes have soil isolation: used to isolate different soil layers or prevent pollutants from seeping into groundwater, such as in landfills, chemical plants and wastewater treatment facilities.
(3) It also has good chemical resistance, can resist acid, alkali, chemical erosion, suitable for a variety of engineering environments, can be used for soil reinforcement and stability, for roads, railways, airports, retaining walls and land backfill and other engineering projects to improve the stability of the structure and carrying capacity.
(4) With tensile tear strength: with a certain mechanical strength and toughness, can withstand a certain amount of stretching, tearing and puncture pressure, enhance the stability of the soil.
(5) Aging resistance: good aging resistance, can resist ultraviolet light, high temperature, low temperature and oxidation, maintain long-term stability.

(2) At the beginning of welding every day (in the morning and after lunch break), it must be tested on the site first, and then formally welded after passing.
(3) The welding of HDPE impervious film should be welded by double-track hot melt welding machine, and only use extrusion welding or hot air gun when repairing, which can not be reached by covering or hot melt welding machine.
(4) During the construction process, the working temperature and speed of the welding machine should be adjusted and controlled at any time according to the temperature and material properties.
(5) The HDPE film at the weld should be fused into a whole, and should not be virtual welding, missed welding or over-welding. Two layers of HDPE impermeable film must be bonded flat and soothing.
