Polyethylene Film (HDPE) Plastic Rolls HDPE Film

High density polyethylene membrane, HDPE membrane is also known as high density polyethylene membrane, HDPE geomembrane, HDPE seepage control membrane, the English name for "High Density Polyethylene Impermeable membrane", referred to as "HDPE membrane".HDPE film is a plastic web composed of HDPE, which is a highly crystalline, non-polar thermoplastic resin. In its raw state HDPE has a milky white appearance with some degree of translucency in micro-thin sections.PE has excellent resistance to most household and industrial chemicals. Some types of chemicals are chemically corrosive, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer does not absorb moisture and has good waterproof vapor properties.HDPE has very good corrosion resistance, electrical properties, moisture resistance, anti-leakage properties, high tensile strength, so it is very suitable for wires and cables, engineering seepage control, aquaculture seepage control, tank seepage control, basement seepage control, seepage control of artificial lakes, etc. HDPE membranes have very good impact resistance, so at room temperature and even in the low temperature of -40F are so. HDPE is a polymer non-toxic, tasteless, odorless white particles, melting point of about 110 ℃ -130 ℃, relative density 0.918-0.965; has good heat resistance and cold resistance. Good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear strength performance, with the rise in density, mechanical properties and barrier properties will be improved accordingly, heat resistance, and tensile strength is also higher; can be resistant to corrosion of acids, alkalis, organic solvents and so on.

Features

1, high impermeability coefficient - impermeable membrane with ordinary waterproof materials can not be compared with the impermeability effect, HDPE impermeable membrane has a high tensile mechanical, its excellent elasticity and deformation ability makes it very suitable for expansion or contraction of the substrate, can effectively overcome the uneven settlement of the substrate, water vapor permeability coefficient K <= 1.0 * 10-13gcm/c cm2spa.

2, chemical stability - impermeable membrane has excellent chemical stability, is widely used in sewage treatment, chemical reaction pools, landfills. Resistant to high and low temperatures, asphalt, oil and tar, acid, alkali, salt and other 80 kinds of strong acid and alkali chemical media corrosion.

3, aging resistance - seepage control membrane has excellent anti-aging, anti-ultraviolet, decomposition resistance, can be exposed to use, the service life of the material up to 50-70 years, for the environment seepage control to provide a very good material guarantee!

4, anti-plant roots - HDPE impermeable membrane has excellent puncture resistance, can resist most of the plant root system

5, high mechanical strength - seepage control membrane has good mechanical strength, tensile strength at break 28MPa, elongation at break 700%.

6, low cost and high efficiency - HDPE impermeable membrane using new technology to improve the seepage control effect, but the production process is more scientific, quick, so the cost of the product is lower than the traditional waterproofing materials, by the actual calculations of HDPE impermeable membrane general engineering to save costs about 50%!

7, construction speed - anti-seepage membrane has a high degree of flexibility, there are a variety of specifications and a variety of laying form to meet the requirements of different projects seepage control, the use of heat fusion welding, weld high strength, construction is convenient, fast and healthy!

8、Environmental protection and non-toxicity - anti-seepage membrane materials are non-toxic environmentally friendly materials, seepage control principle is an ordinary physical change, does not produce any harmful substances, is the best choice for environmental protection, aquaculture, drinking water pool.

HDPE geomembrane characteristics

HDPE geomembrane is one of the three main geosynthetics commonly used in landfill projects (plus geonets and geotextiles), and its seepage control performance is a measure of whether the sanitary landfill meets the environmental requirements of the main indicators.

HDPE geomembrane is usually made of a continuous thin layer of polymer, and is not absolutely impermeable to water and gas, only relative to geotextiles or fill or even clay is impermeable to water and gas. Its water vapor permeability test measured data in 0.5 × 10-10 ~ 0.5 × 10-13cm / s between. Therefore, the geomembrane of the sanitary landfill is mainly used in the landfill.

Application Areas

1. Environmental protection, sanitation (such as domestic garbage landfill, sewage treatment plants, power plant regulating pool, underground foundation waterproof seepage control, plant roof moisture industry, hospital solid waste, etc.)

2. Water conservancy (e.g. seepage control of dams of rivers and lakes and reservoirs, leakage control, reinforcement, seepage control of drains, vertical heart wall, slope protection, etc.)

3. Municipal engineering (highway, subway, underground engineering of buildings, planting roof, roof garden seepage control, sewage pipe lining, etc.)

4. Gardening (roof gardens, artificial lakes, rivers, cisterns, golf course ponds lining, slope protection, green lawn waterproofing moisture, etc.)

5. Petrochemical (chemical plants, refineries, gas station tanks seepage control, chemical reaction tanks, sedimentation tank lining, secondary lining, etc.)

6. Mining industry (washing tank, heap leaching tank, ash dump, dissolving tank, sedimentation tank, yard, tailings bottom lining seepage prevention, etc.)

7. Transportation facilities (foundation reinforcement of highways, seepage control of culverts)

8. Agriculture (reservoirs, drinking water pools, water storage ponds, seepage control of irrigation systems, agricultural farming, such as pig farm septic tanks)

9. Aquaculture (aquaculture ponds, intensive, factory farming ponds, fish ponds, shrimp pond lining, sea cucumber circle slope protection, etc.)

10. Salt industry (salt crystallization ponds, brine ponds thatching, salt film, plastic thatching film for salt ponds)
