HDPE geomembrane, the full name of "high-density polyethylene geomembrane", has excellent stress resistance, low temperature resistance, aging resistance, corrosion resistance, and can be used in the operating temperature range of 60 to minus 60 degrees Celsius. HDPE geomembrane has a long service life, up to 50 years.

How to perform a quality test of HDPE Geomembranes?

The design should be carried out strictly according to the technical specifications and the five quality stages of preparation, laying, gluing, inspection and filling of HDPE Geomembranes should be reviewed.

All welds should be inspected visually at all times. After welding the HDPE-Geomembrane, the exposed edges of the weld seam can be pulled through with force. There should be no missing welds, open welds or false welds. Blow 0.2 MPA into the respiratory tract and the weld seam will not leak for three to five minutes and there must be no open weld seam.

Extruded HDPE Geomembrane welding seams and suspicious leaks can be checked with a vacuum leak detector, apply energy to the vacuum pump and adjust the pressure drop in the vacuum box to no less than 0005 MPA, and there should be no air leak within thirty seconds.

What are the properties of HDPE Geomembranes?

The structure of the HDPE Geomembrane is divided into a fabric and a film and two tissues and a film, with a width of 4-6 m and a weight of 200-1500 g/ m2. It has high physical and mechanical properties such as tensile, tear and burst resistance. The product is characterized by high strength, good elongation, large deformation modules, acid and alkaline resistance, corrosion resistance, ageing resistance and good anti-leakage performance. It can meet the requirements of deep-sea construction such as acidification, insulation, reinforcement, cracking and strengthening in the water industry, municipal administration, construction, transport, underground, tunnel and engineering. The HDPE Geomembrane consists of high polymer materials and is replaced in the production process with anti-aging agents, so that it can be used in environments with unconventional temperatures. HDPE Geomembrane can therefore be used in general for the treatment of dams, drainage ditches and the treatment of landfills against pollution.

What are HDPE Geomembranes used for everyday life?

1. HDPE Geomembrane is suitable for environmental protection and hygiene: such as landfills, sewage treatment plants, power plant control tanks, industrial waste, hospital waste, etc.;

2. HDPE Geomembrane is suitable for water protection projects: such as obstruction, strengthening of rivers, lakes, reservoirs and dams, obstruction of water channels, vertical core walls, slope protection, etc.;

3. HDPE Geomembrane is used in municipal technology: subway, underground building, roof planting, roof garden, sewage protection;

4. HDPE Geomembrane is suitable for agriculture: protection against pollution of reservoirs, drinking water ponds, storage ponds, waste treatment facilities and irrigation systems;

5. HDPE Geomembrane is suitable for the aquaculture industry: Intensive, bulk retention, fish ponds, garment of shrimp signs, seacucumber ring hanger protection, etc.;

6. HDPE Geomembrane is suitable for the salt industry: salt-field crystallization sheet, sun-pond straw cover, salt film, salt-rich plastic straw foil.
