Landfill is the most commonly used method for solid waste and domestic waste treatment. It has the characteristics of low cost, large processing capacity and simple operation In many developed countries and developing countries widely used.
HDPE geomembrane is the most widely used impervious material in landfill because of its high strength, stable chemical properties and excellent aging resistance.
Landfill often involves such problems as highly toxic and hazardous leachate and hazardous chemicals. Impervious materials used for landfill liner must have good impervious performance,good degradation performance and good oxidation resistance.
Used for landfill anti-seepage geomembrane shall meet the following system,
HDPE geomemebrane membrane thickness should not less than 1.5 mm. Decided to the stress state of membrane thickness, durability, penetration resistance,etc. The ability to resist damage.
HDPE geomembrane width should not be less than 7 m. The wider the width, the stronger the leakproofness.
HDPE geomembrane should be used for slope.The secondary forming method can effectively ensure the stability of various indexes of the sheet and improve the overall engineering quality.
