In the transportation, processing, storage and other aspects of the petrochemical plant oil, there is inevitably a large or small leakage phenomenon. If the protection measures are not tight, the oil will directly leak into the sea through the pores of the soil, polluting the water body and causing marine pollution. To protect the environment, it is necessary to take care of the leakage from the root cause. Geomembranes are widely used in major anti-seepage projects.
Advantages of geomembrane as anti-seepage material in oil mine area
Geomembrane characteristic high anti-seepage coefficient: Geomembrane is made of high-quality high-density polyethylene raw resin, which is made by co-extrusion technology. It has high molecular density and low liquid permeability. It has anti-seepage effect which is unmatched by ordinary waterproof materials. The penetration effect is extremely strong.
It has high tensile strength and mechanical properties: its excellent elasticity and deformability make it very suitable for expanding or shrinking the base surface, which can effectively overcome the uneven geomembrane settlement of the base surface.
Chemical stability: Geomembrane has excellent chemical stability, high and low temperature resistance, asphalt resistance, oil and tar, acid, alkali, salt and other chemical solutions. Widely used in dry sewage treatment, chemical reaction tanks, landfills.
Anti-aging performance: HDPE geomembrane has excellent anti-aging, anti-UV, anti-decomposition ability, excellent tear resistance, puncture resistance, low brittleness, small thermal deformation, can be used barely, and the service life of materials is 50-70 years. , to provide a good guarantee of environmental protection for environmental seepage.
Environmentally friendly and non-toxic: HDPE geomembrane materials are non-toxic and environmentally friendly materials. The anti-seepage principle is a common physical change and does not produce any harmful substances. It is a better choice for environmental protection, breeding and drinking water pools.
Low cost and high efficiency: the geomembrane adopts new technology to improve the anti-seepage effect, but the production process is more scientific and quicker, so the product cost is lower than the traditional waterproof material. The actual project using HDPE geomembrane should save 50% of the cost. about.
The geomembrane construction is simple and convenient, the speed is fast, the quality is light, and it is easy to transport; the anti-seepage film is light in weight, the finished product is in the form of a roll, and has high flexibility, and is convenient for on-site laying to meet the needs of different construction sites. There are a variety of specifications and a variety of laying forms to meet different engineering anti-seepage requirements, using hot-melt welding, high weld strength, convenient and fast construction.
