                                                                                                           Common Challenges in the Application of Geomembrane

Strongly oxidizing medium corrosion

Long-term immersion in strong oxidizing media such as hydrogen peroxide and ozone water causes the rapid depletion of the anti-oxidant in ordinary geotextiles, resulting in chemical corrosion perforation and a high risk of seepage failure. The oxidation induction time is shortened by more than 50%, and the material lifespan is only 1-2 years. 

Challenges in highly corrosive environments

Hydrometallurgy involves high-concentration acids, bases, and heavy metal solutions. Traditional materials are prone to corrosion and aging, leading to leakage risks. Leakage can  cause environmental pollution (soil and groundwater contamination), production shutdowns, and even face hefty environmental penalties. 

Poor adaptability to extreme conditions

Under extreme conditions such as high temperature (with some molten liquid temperatures exceeding 60℃), high pressure, and mechanical wear, ordinary geotextiles are prone to deformation and rupture. 

The hidden costs are high.

Leakage leads to the loss of precious metals and a sharp increase in ecological restoration costs, with significant losses resulting from a single incident.

                                                                                                               5-layer co-extrusion blow molding process

1. Superb chemical corrosion resistance: The formula is resistant to strong oxidation corrosion, and its ability to resist the synergistic corrosion of hydrogen peroxide-ozone strong oxidation and high-concentration acids, alkalis, salts, etc. has been enhanced by 3 times.

2. Extreme working condition adaptability: The five-layer co-extrusion process and nano-functional layer enhancement design ensure a design lifespan of 5-8 years, reducing maintenance frequency by 60% and meeting the requirements of the wet smelting market.
