non-biodegradable geo-textile bag Manufacturers

HDPE geomembrane, also known as high-density polyethylene film, is produced with high crystallinity, non-polar medium (high) density polyethylene thermoplastic resin as raw material, with a density of 0.94g/cm3 or higher.

As we all know, the main equipment for geomembrane production in my country is divided into two types: laminating machine and blown film machine.

With the growth of the service life of expressways, problems such as network cracks, grooves, and cracks have appeared. It not only affects the stability and comfort of the car, but also causes surface water to penetrate into the road base and weaken the bearing capacity of the road base.

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.

The main function of using composite geomembrane in water-saving projects is to improve the anti-seepage effect of the entire project. From this perspective, the overlap of geomembrane is very important.

The special breathable performance of stitched polyester cloth ensures the breathable performance of ground waterproof, so that the water vapor produced by the temperature change can be discharged immediately under the ground waterproof, and the bond of ground waterproof and datum is not prone to the harm of water vapor, so as to ensure the lasting service life of ground waterproof.
