Geomembranes are waterproof and barrier-type materials made of polymer as the basic raw material. It is mainly divided into low-density polyethylene (LDPE) geomembranes, high-density polyethylene (HDPE) geomembranes, and EVA geomembranes.
It has the following characteristics:
1. Complete specification of width and thickness.
2. Excellent resistance to environmental stress cracking and chemical corrosion resistance.
3. Excellent chemical corrosion resistance.
4. Large temperature range and long service life.
5. Used in landfill, tailings storage site, channel impermeability, dam impermeability, subway engineering, etc.
HDPE geomembrane is made of virgin resin through special production, with a smooth and flat surface on both sides. It is designed for flexible geomembranes. So how to buy the right HDPE geomembrane?
Here is the content list:
How to properly purchase an HDPE geomembrane?
How to maintain HDPE geomembrane?
At present, there are two international production methods, namely the blown film process and the flat extrusion process. The two different production processes have different requirements for HDPE Geomembrane Smooth resin raw materials: the melt index of resin raw materials for the flat extrusion process is generally 0.11 g/10 minutes, while the melt index of resin raw materials for the blown film process is generally 1.0 g/10 minutes. The two production methods are different, but the output geomembrane can meet the standard.
The difference is that geomembranes produced by the flat extrusion process have a smoother surface, while those produced by the blow molding process are more uniform. Generally speaking, geomembranes produced by the flat extrusion process are faster and more productive. However, we have 3 production lines for the blow molding process, which can also meet the needs of our customers. Therefore, when purchasing HDPE geomembranes, you should choose different HDPE geomembranes made by different processes according to your needs. Each of the above two production processes has its characteristics and can meet different practical needs for geomembranes.
In construction you must do a good job on HDPE geomembrane protection measures, only in this way can better play its performance, so that we can save costs and improve the effectiveness of the project. First of all, we should pay attention to the product not being eroded by the wind and rain, HDPE geomembrane into the field when needed for laying, if this can not be done, to cover with colored strips of cloth or film, stored in a flat site. Special attention should be paid when using HDPE geomembrane for landfill. Secondly, pay attention not to let the mud block, dirt, debris, and other foreign objects appear, after laying not to let the vehicle crush, otherwise destroy the HDPE geomembrane is equal to doing useless work.
