Why Geomembrane Plays an Important Role in Mining Treatment
In the mining treatment project, the geomembrane is a very necessary material. The treated tailings can be used as cement, tiles, aerated concrete, permeable bricks, refractory materials, fire insulation materials, glass, Raw materials such as ceramsite and concrete aggregate, tailings sand can replace part of the machine-made sand for making concrete, road construction, pavement materials, etc.
When the tailings contain toxic or radioactive substances or heavy metal ions, in principle, it is not allowed to contain harmful substances to contaminate groundwater, so anti-seepage treatment should be done.
Geomembrane uses plastic film as the impermeable base material, and the geomembrane material compounded with non-woven fabric, its impermeability depends mainly on the impermeability of the plastic film. Geomembrane is a waterproof barrier type material that uses high molecular polymer as the basic raw material.
At present, the plastic films used for anti-seepage at home and abroad mainly include composite geomembrane, high-density polyethylene (HDPE) geomembrane and EVA geomembrane, which has low temperature resistance and good frost resistance.
