The permeation principle is a general physical change and does not produce any harmful substances.
The melting point is about 110-130 and the relative density is 0.918-0.965.
Polyethylene is a high molecular polymer.
More than 80 strong acid and alkali chemical media such as high temperature, low temperature, asphalt, oil and tar, acid, alkali and salt are corroded.
Geotextile (properties of impermeable membrane) 1.
Chemical stability, stiffness, toughness, mechanical strength, internal environmental stress cracking and tear strength, density increase, mechanical properties and blocking properties, heat resistance and tensile strength increase, which will cause corrosion resistance to acid, alkali and organic solvents.
HDPE impermeable membrane has high-strength tensile mechanical properties, good elasticity and deformation capacity, which is very suitable for the expansion or contraction of the foundation, can effectively overcome the uneven settlement of the foundation, and the water vapor permeability coefficient is 2 Chemical stability – permeable membrane has good chemical stability and is widely used in sewage treatment, chemical reaction tank and landfill.
It is estimated that the general engineering savings for the actual HDPE diaphragm are about 50%.

According to different specifications, different layout forms meet the anti-seepage requirements of different projects.
High impermeability coefficient – impermeable membrane has the impermeability effect unmatched by traditional waterproof materials.
It is the preferred choice for environmental protection, aquaculture and drinking water.
Fast construction speed – the earth rock membrane has high flexibility.
Hot melt welding is adopted, with high welding strength, convenient construction, fast and healthy 8 No environmental protection toxicity – the materials used in the policy permeable membrane are non-toxic environmental protection materials.
High quality polyethylene raw water resin, high density polyethylene 97.5%, about 2.5% of carbon black, anti-aging agents, antioxidants, UV absorbers, stabilizers and other excipients of the main ingredients are now widely distributed throughout the world, the standard name is polyethylene earth membrane, mainly made from semi transparent white opaque thermoplastic resin polyethylene resin.
However, due to the more scientific and faster production process, the production cost is lower than that of traditional waterproof materials.
Plant root resistance – HDPE has good penetration and puncture resistance, and can resist most plant roots 5 High mechanical strength – the policy has excellent mechanical strength, breaking tensile strength of 28Mpa and breaking elongation of 700% 6 Low cost and high profit – HDPE diaphragm adopts new technology to improve the anti-seepage effect.

Anti aging performance – the protective film has excellent anti-aging, UV and decomposition functions, and can provide a good material guarantee for bare metal use, material life of 50-70 years and environmental penetration.
It is a non-toxic, tasteless and tasteless white particle.
The film has good heat resistance and cold resistance.
