1. Product introduction

Geomembrane is a polymer film used in engineering and environmental applications, typically made from plastic materials such as polyethylene (HDPE), etc. It has the functions of waterproofing, impermeability, isolation and protection, and is widely used in various engineering projects and environmental protection.

Geomembrane plays an important role in the field of environmental protection and basic engineering, and can effectively improve the stability of engineering structures and protect the environment. Choosing the right material and correct construction method is crucial for geomembrane to play the best role.

Haoyang Environment is a professional supplier of geomembrane, with the country's largest radius of geomembrane production equipment and a variety of production lines, is one of the main suppliers of China's South-to-North water diversion project. In the USA market, this kind of geomembrane is very popular. As the most professional geomembrane manufacturer in China, our main market is also the USA.

2.How is 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.

5.HDPE geomembrane weld field detection method:

At present, there is no good method for on-site inspection of welds, generally more visual inspection, to see whether the two welds are smooth, clear, wrinkle-free, transparent, no slag, bubble leakage point, melting point or weld bubble edge.

(1) Both ends of the weld are welded with a welding gun, and then the cylinder with a pressure gauge is used to clamp the gas needle, and the gas needle is inserted into the hole between the weld, the detection distance of each section is about 1.5m ~ 3.0m, and the pressure is controlled at 0.5 ~ 2mpa according to the requirements of the geosynthetic material test regulations, and the time is about 30s. When pumping, if there is a leak in the weld between the gas and the gas needle, then as long as the gas needle part is stuffed with plasticine, hit the air, press the finger in front of the gas needle, if the observation is more than 30 seconds, the gas will not leak, it is regarded as qualified connection.

(2) When testing with a microscope, put the microscope in a suspicious place, such as leakage points, virtual points, with a welding torch or adhesive treatment.

7. Special application of rough geomembrane

Rough geomembrane is a kind of geomembrane with special texture or uneven surface, which is characterized by a certain roughness rather than smooth surface.

The application of rough geomembrane is mainly reflected in the following aspects:

（1）Improved friction and slip resistance: The rough surface structure increases the friction between the geomembrane and soil or other materials, helping to improve its slip resistance and stability. Therefore, in slope protection, dam or retaining wall and other projects, rough geomembrane can better prevent soil sliding and erosion.

（2）Enhance the combination of geomembrane and soil: rough surface design can increase the binding force between geomembrane and soil, which is conducive to the firm combination of geomembrane and soil, and reduce the risk of geomembrane displacement in engineering.

（3）Soil and water conservation and erosion prevention: In soil and water conservation projects such as banks, ditches, earth and rock slopes, rough surface geomembrane can effectively slow down the flow rate, reduce the flow erosion, and protect the soil from erosion.

（4）Improve drainage function: the rough surface structure helps to discharge the geomembrane water, improve the drainage performance of the lower part of the geomembrane, and prevent water retention between the geomembrane and the surface.

（5）Ecological landscape design: In ecological garden and landscape design, rough geomembrane is often used to simulate natural terrain and create an environment closer to natural ecology.

In general, because of its special surface structure, rough geomembrane is more suitable for engineering scenes that need to enhance the binding force between geomembrane and soil, improve the friction force or achieve soil and water conservation.
