Somebody help me. ! ! How to write the instructions for purchasing HDPE geomembrane in landfill? Request for instructions on making slope protection film materials. !

1. The impervious geomembrane for water conservancy projects is suitable for environmental protection and sanitation, such as landfill, sewage treatment plant, sodium bentonite waterproof blanket, power plant regulating tank, industrial and hospital solid waste, etc.

2. Impervious membrane is suitable for water conservancy projects, such as seepage prevention, plugging and reinforcement of dams in rivers, lakes and reservoirs, seepage prevention of channels, vertical core walls and slope protection.

3. Impervious membrane is suitable for municipal engineering: subway, underground engineering of buildings, planting roofs, impervious roof gardens and sewage pipes;

4. Polyethylene impervious membrane is suitable for gardens: artificial lakes, rivers, reservoirs, the bottom of golf courses, slope protection, green lawns, etc. ;

5. The high-density polyethylene composite geomembrane is suitable for petrochemical industry: chemical plant, oil refinery, oil storage tank seepage prevention, chemical reaction tank lining, sedimentation tank, secondary lining, etc.

6. Polyethylene geomembrane is suitable for mining industry: ore washing pond, heap leaching pond, ash yard, dissolving pond, sedimentation pond, storage yard, tailings seepage control, etc.

7. Low density polyethylene film is suitable for traffic facilities: highway foundation reinforcement and culvert seepage control;

8. Impervious membrane is suitable for agriculture: seepage prevention of reservoirs, drinking pools, water storage ponds and irrigation systems;

9. The membrane is suitable for aquaculture: intensive and industrial aquaculture ponds, fish ponds, shrimp ponds and sea cucumber ponds for slope protection;

10, the high-density polyethylene impervious membrane is suitable for salt-making industry: saltworks crystallization pond, brine pond cover, salt film and salt pond plastic film.

Short fiber geotextile

Geotextile. They can play a good role in filtration, isolation, reinforcement and protection, and are widely used geosynthetics. The tensile strength of filament is higher than that of short silk, so it can be used according to specific requirements. The finished product is cloth-like, generally 4-6m wide and 50- 100m long. Geotextiles are divided into woven isolation maintenance geotextiles and nonwoven isolation maintenance geotextiles. Geotextile has excellent filtration, isolation, reinforcement and protection, high tensile strength, good permeability, high temperature resistance, frost resistance, aging resistance and corrosion resistance.

Composite composite impervious geomembrane

Earth dams, rockfill dams, masonry dams and paving concrete dams; Horizontal impervious blanket in front of dike and dam, vertical impervious layer of foundation; Tailings dam, dam body and reservoir area; Construction cofferdam; Channels and liquid storage tanks (pits and pits); Waste yard; Anti-seepage lining of subway, basement, tunnel and tunnel; Highway, expressway and railway subgrade; Prevention and control of salinization of subgrade and other foundations; Expansive soil and collapsible loess waterproof layer; Roofing leak-proof products: two cloths and one membrane (geotextile for protection is added on both sides of the impermeable membrane) and one cloth and one membrane (geotextile for protection is added on one side of the impermeable membrane).

Width: 46m specification: the thickness of membrane material is 0.2mm0.8mm, and the protective geotextile 100g/m2800g/m2 (produced by our factory, in line with national standards).

Expansion waterproof pad

Bentonite impervious blanket consists of two layers of geotextile and bentonite layer. The upper nonwoven geotextile penetrates the bentonite layer by pinhole punching method, and is integrated with the lower geotextile (woven or nonwoven). This method can form a strong mechanical adhesion between two layers of cloth. Then, the fabric is repaired and permanently reinforced in its position through a heat treatment process, that is, a thermal bonding process. Using the characteristics of sodium bentonite swelling in water, people naturally apply it to hot wedge geotechnical composite clay gasket products. When it meets water in a closed state, bentonite will swell to form a clay layer with low permeability, which is as waterproof as compressed clay several feet thick. Its unique properties, including increasing internal shear strength and long-term creep resistance, make the composite bentonite impervious blanket suitable for various waterproof lining systems.

Special waterproof board for tunnel

Subway waterproof board is the first choice for tunnel and dam waterproof engineering in China. EVA and ECB subway waterproof board is a kind of composite geomembrane, which is made of ethylene vinyl acetate polymer with special additives and anti-aging, through two-stage extrusion and three-roll calendering. It has excellent weather resistance, low temperature resistance, flexibility, large elongation and good impermeability. Railway, subway, water conservancy, tunnel, highway, waterproof and drainage engineering, dam protection engineering, roof waterproofing, seepage prevention, landfill and port construction. Industrial and domestic reservoirs, golf courses, swimming pools, etc.

The elongation of HDPE impervious membrane is over 700%, which can resist cracking and leakage caused by uneven settlement.

1. Tamp and level the pavement to be paved, dig the blind ditch for exhaust and drainage, and lay the impervious membrane after laying the blind pipe.

2. Irregular rivers and streams can be laid vertically along the axis, which can avoid wrinkles and bulges. After measuring a large area of artificial lake, the best laying scheme can be selected according to the specifications of impervious membrane.

3. In welding, difficult places such as pipe joints, yin and yang angles, corners, etc. It can be welded with a hot air blower.

4. Anchoring of gentle slope revetment, directly digging anchoring ditch and backfill soil for anchoring; Vertical hard revetment can be anchored by anchor nails and battens; For concrete slope protection, you can dig the foundation first, then lay the film, and then use concrete retaining wall to protect the slope.
