Details
Composite geomembrane, widely used in channel anti-seepage engineering.
Composite Geomembrane uses plastic film as the anti-seepage base material, and is a geotechnical anti-seepage material compounded with non-woven fabrics. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film.
The plastic films for anti-seepage applications mainly include polyvinyl chloride (PVC) and polyethylene (HDPE, LDPE, LLDPE). Corrosion resistance, low temperature resistance, good frost resistance. The main mechanism is that the water-impermeability of the plastic film blocks the leakage channel of the earth dam, and it can withstand the water pressure and adapt to the deformation of the dam body with its large tensile strength and elongation; and the non-woven fabric is also a kind of polymer short fiber chemical The material, formed by needle punching or thermal bonding, has high tensile strength and extensibility. After it is combined with the plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also has a rough surface due to the non-woven fabric. , which increases the friction coefficient of the contact surface, which is beneficial to the stability of the composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemical effects, and are not afraid of acid, alkali and salt erosion.
Features
Flexibility is good , except of a geotextile's isolation , drainage , reinforcement , protective functiona , it isalso impermeable .
Application
It can be widely used in areas of garbage burying, waste disposal, tail minerals storage and underground construction projects.
