Product Description
Blow molded geomembrane is a type of anti-seepage material that uses high-density polyethylene (HDPE) as the raw material. The production process of blow molded geotextile mainly includes the following steps:
1.Ingredients: Select appropriate high-density polyethylene raw materials according to design requirements. An appropriate amount of additives such as carbon black, antioxidants, and UV absorbers need to be added to the raw materials to improve the antioxidant and UV resistance properties of the geomembrane.
2.Melting: The selected high-density polyethylene raw material is melted through an extruder to form a molten plastic.
3.Blow molding: Molten plastic is blown into a thin film shape through the blow molding machine head under a certain pressure. During the blow molding process, the plastic film is blown out from the circular cross-section nozzle under the action of the blow molding machine, forming a thin film.
4.Cooling: The blown geosynthetic film is gradually cooled to room temperature through a cooling device, making it easier for subsequent processing.
5.Traction: The cooled geotextile is pulled through a traction device at a set speed and direction to achieve the required thickness.
6.Cutting: According to the design specifications, cut the geomembrane after traction to form a specified length and width of geomembrane.
7.Inspection: Conduct quality inspection on the produced geotextile, including thickness, strength, toughness, oxidation resistance, and other aspects. Only qualified geomembranes can proceed to the next process.
8.Packaging: Qualified geotextile films are packaged for storage and transportation.
The key to the production process of blow molded geotextile is the blow molding process, which directly affects the quality and performance of the geotextile. Through reasonable blow molding parameters and process control, geomembranes with good anti-seepage performance, strength, toughness, and weather resistance can be produced.
It should be noted that there are multiple specifications and quality levels in the production process of blow molded geotextiles, and geotextiles with different production standards have differences in performance and price. When selecting geomembranes, appropriate production processes and specifications should be selected based on actual needs.

Installation Instructions
Geomembrane, as an important geosynthetic material, is widely used in geotechnical and civil engineering. Its excellent anti-seepage, corrosion resistance, deformation adaptability, and frost resistance make it play an important role in various engineering projects. Below, we will provide a detailed introduction to the installation steps and precautions for geomembranes.
Installation steps of geomembrane:
Preparation work:
Ensure that the construction site meets the requirements, remove debris and dust, and ensure that the foundation is flat and solid.
Geomembranes should be avoided from being dragged or hard pulled during transportation and storage to avoid damage.
Measurement and cropping:
Measure the dimensions of the laying area, accurately measure the relevant dimensions before cutting the geomembrane, and cut according to actual needs.
When cutting, it is not advisable to be too tight, and a margin of 1.5% should be left for local sinking and stretching.
Laying:
When laying geomembranes, they should be kept flat and tightly pressed from bottom to top, between membranes and between membranes and the substrate.
The laying of the membrane should be slightly loose to avoid leaving bubbles at the bottom of the membrane.
The laying sequence is from the slope to the bottom of the field. When laying the slope, the direction of the film should be basically parallel to the maximum slope line.
Joint treatment:
The longitudinal joints of adjacent frames should not be on the same horizontal line and should be staggered by more than 1 meter from each other.
The longitudinal joint should be at least 1.5 meters away from the foot of the dam or the bend, and should be placed on a flat surface.
The overlap width between membranes is generally not less than 10 centimeters.
Fixation and protection:
The geotextile membrane after laying should be pressed with sandbags to prevent wind movement.
At corners and deformed areas, detailed records should be made on a dedicated form and numbered.
During the laying process, it is important to avoid sharp objects piercing the geomembrane.
Welding:
When welding geomembranes, hot melt welding or special adhesive bonding should be used.
Before welding, it is necessary to ensure that the two sides of the PE single film at the joint are flat, wrinkle free, and overlap with a certain width.
When welding, adjust the temperature and speed to ensure firm welding.
Inspection and backfilling:
After the laying and splicing of geomembranes are completed, quality inspection should be carried out.
Backfilling operations can only be carried out after ensuring that there are no damages, bubbles, welding leaks, or other issues.
Notes:
Construction environment: Ensure the cleanliness of the construction site and prevent dust and debris from contaminating the geomembrane.
Material protection: Avoid damaging the geomembrane during transportation and storage, and pay attention to precise dimensions when cutting.
Joint treatment: The joint is the key to anti-seepage, ensuring firm welding and avoiding leakage.
Climate factors: Protective measures should be taken on cloudy and rainy days to ensure that the bonding surface is dry.
Safety protection: The construction site should strengthen labor protection measures for employees.
In summary, the installation of geomembranes needs to be strictly carried out in accordance with construction specifications, from base treatment, cutting, laying, jointing to final fixation and backfilling, each step is related to the quality and durability of the project. At the same time, attention should be paid to environmental and safety protection at the construction site to ensure smooth construction progress
