HDPE Geomembrane : Waterproof Material

What is hdpe geomembrane?

HDPE geomembrane, full name is high density Polyethylene geomembrane, general density of 0.94g/cm or more geomembrane is called hdpe geomembrane.

HDPE black membrane (geomembrane) materials in the field of environmental protection in the following two main uses: the first is the role of seepage control of sewage. Prevent sewage from affecting underground water bodies. The second is the anaerobic link in sewage treatment, i.e. black membrane digester, black membrane biogas project.

Its main raw material is high-density polyethylene, composite HDPE membrane is also known as high-density polyethylene membrane, HDPE geomembrane, HDPE impermeable membrane, HDPE geomembrane, also known as hdpe impermeable membrane, is a waterproof isolation membrane produced by HDPE raw materials + high-quality double-resistant masterbatch, through the laminating calendering or blown film co-extrusion process.

HDPE membrane is a plastic coil composed of HDPE, its HDPE is a high crystallinity, non-polar thermoplastic resin, the appearance of the original state HDPE is milky white translucent.

Classification and function of hdpe geomembrane, glossy and sprayed rough HDPE geomembrane is a flexible waterproof material with high impermeability coefficient;

Geomembrane is widely used in artificial lakes, golf courses, livestock ponds, sewage ponds, municipal engineering and other seepage control projects.

HDPE geomembrane Advantage

HDPE geomembrane has good heat resistance and cold resistance, HDPE geomembrane is also known as (high-density polyethylene geomembrane) its use of the ambient temperature of high temperature 110 ℃, low temperature -70 ℃;

HDPE glossy geomembrane has good chemical stability, can resist strong acid, alkali, oil corrosion is a good anticorrosion material; HDPE geomembrane has a high tensile strength, can meet the needs of high-standard engineering projects;, lotus root ponds, fishponds, aquaculture seepage control membranes, seepage control membranes for fishponds, composite geomembranes, garbage geomembranes, methane digester geomembrane specification models are complete and durable.

HDPE geomembrane is recognized by the project and widely used without its own flashpoints, the following list for you: the first is its seepage control performance, it has the common seepage control materials can not match the seepage control effect; the second tensile strength and elongation at break index is high, the tensile strength can be up to 27 MPa, the elongation at break ≥ 700%; the third chemical stability and aging resistance performance is high, not only can be strong acids and alkalis medium corrosion, but also can be strong acids and alkalis medium corrosion, but also can be strong acids and alkalis, and also can be strong acids and alkalis. Strong alkali medium corrosion, but also anti-aging, anti-ultraviolet, decomposition, anti-freezing, can be used in the open air; fourth low cost construction speed, HDPE geomembrane standard size 6 meters wide and 50 meters long, a single volume area of 300 square meters, a welding master a day will be able to weld 3,000 square meters, which is the traditional cement seepage control and sbs waterproofing roll-roofing can not be compared.

In recent years HDPE geomembrane not only in the environmental protection seepage control project shine, in the use of agricultural water resources has also taken very good results, part of the region water shortages, the soil itself has poor water storage capacity, in drinking and irrigation are facing huge challenges, with HDPE geomembrane directly laid in the cisterns, you can effectively prevent the loss of water resources, and effectively solved the problem of irrigation in the local area.

What is the difference between HDPE geomembrane and LDPE geomembrane?

The difference between HDPE geomembrane and LDPE geomembrane mainly lies in the structure and performance of the material.HDPE geomembrane has high density and strength, good chemical corrosion resistance, and is suitable for demanding engineering environments; whereas LDPE geomembrane has low density and toughness, and is suitable for general requirements of the engineering scene.
