Geomembrane

Geo-membrane is produced by a method of three layer co-extrusion model. The raw material is processed at 200° C by fusing and coextrusion, whose basic properties are kept during the producing process.

Material: HDPE
Thickness: 0.3mm-3.0mm
Width: 1.0m-7.0m
Quality Inspection Standard: GB/T17638-1998
Quality Control Measure: Strictly comply with ISO9001: 2000
Features:
1) Can bear chemical erosion.
2) A wider using temperature range and a longer using life.

Application:
It can be widely used in areas of garbage burying, waste disposal, tail minerals storage and underground construction projects.

Application
The usage of the HDPE/LDPE membrane
As a new type of material, HDPE/LDPE impervious membrane has outstanding performance, stability, and can be processed as required. It has been widely used in dam, reservoir, but also channels, sewage ponds, swimming pools, buildings, underground structures, garbage collection, environmental engineering fields. In 1930's developed countries started to use this technology widely and our country gradually promote the use of HDPE impervious membrane in some projects from the 1980s.

1. Environmental protection, sanitation (such as landfill, waste water treatment, toxic and harmful chemicals disposal sites, storage of dangerous goods, industrial waste, construction and demolition waste, etc. )
2. Water (such as impervious, stop water loss, and reinforcing of lakes, and the impervious, slope protection, etc. )
3. Municipal projects (underground subway, engineering underground and reservoirs on the roof, and the park on the roof, the lining in the sewage pipes, etc)
4. Garden (artificial lakes, ponds, the lining of tank in golf course, slope protection, etc)
5. Petrochemical (chemical plants, oil refineries, oil tank of fill stations, chemical reactions pond, the lining of settling basin, second lining, etc)
6. Mining (washing and selecting pool, heap pool, sherry, dissolving pool, settling basin, stock dump, lining of tailing pond, etc)
7. Agriculture (reservoirs, drinking water tank, water storage pond, irrigation systems)
8. Aquaculture (fish ponds, the lining of breeding shrimp tank, slope protection of sea slug tank)
9. Salt industry (crystallization pond, thatch of salt pond, salt membrane, plastic thatch of salt pond.
