Production & Package
BPM smooth geomembrane is a kind of high molecular polymer as the basic raw material of the waterproof barrier material.
Selection of high quality polyethylene resin as raw material, adding carbon black antioxidant,anti-aging and UV-resistance component. It adopted the first class automatic production equipment and three-layer pressing technology.
Mainly divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and linear low density polyethylene (LLDPE) geomembrane.
All products are in accordance with GB, GRI and ASRM standard .
Product performance:
1.Excellent chemical resistance to (Corrosion);
2.Outstanding resistance to stress cracking capacity (Resistance to environmental stress cracking);
3.The lowest permeability;
4.Excellent uv resistance;
5.Stable low temperature embrittlement resist
6.Width and thickness specifications complete, low cost and simple construction.
Function :Impermeable, Leakproof, Moistureproof.
Applications:
Aquaculture: Geomembrane liners can be used as fish ponds, shrimp pond, and other aquaculture.
Landfill: The use of main parts of the bottom of the landfill liner, landfill sealing cover, leachate regulating pool liner, etc.
Water Treatment System: Geomembrane is applied to the adjustment of the power plant and sewage treatment plants pool;and a series of water treatment systems.
Mining: Geomembrane suitable mining: washing pool, pool heap leaching, heap yard, dissolving tank, storage area, the bottom line of the tailings seepage control, etc
More Applications: Environment protection and sanitation, water conservancy, municipal projects, landscaping, petrochemical industry, salt industry, agriculture, ect.
