Durability and Environmental Friendliness of Long Fiber Geotextile
Product Introduction
Long fiber geotechnical fabric, also known as polyethylene long fiber non-woven geotechnical fabric, is an important geosynthetic material. It is made by the method of polyethylene long fiber web forming and consolidation, with its fibers arranged in a three-dimensional structure. This material has excellent mechanical properties, longitudinal and transverse drainage performance, good extensibility, and high resistance to biological, acidic, and alkaline environments, as well as aging, demonstrating excellent chemical stability.
Main Features
-
Mechanical Properties: Long fiber geotechnical fabric has high strength and high tensile strength, which can effectively enhance the tensile strength and anti-deformation ability of soil, thereby improving the stability of building structures.
-
Drainage Performance: Due to the fluffy structure of the long fiber geotechnical fabric, it can effectively control the drainage performance on the surface of geotechnical engineering projects, while also possessing excellent filtration properties and corrosion resistance.
-
Durability: Long fiber geotechnical fabric has excellent heat and light resistance, capable of withstanding various natural soils, moisture, and microbial corrosion for an extended period.
-
Environmental Friendliness: Long fiber geotechnical fabric is free from chemical additives and does not undergo heat treatment, making it an environmentally friendly construction material.
Product Application
Long fiber geotechnical fabric is widely used in various civil engineering and water conservancy projects, specifically including: Hydraulic Engineering: Filtering for dams and slope protection, isolation and seepage prevention in canals.
Traffic Engineering: Used for basic isolation, filtration, drainage, embankments, retaining walls, and reinforcement of road surfaces in highways, railways, and airport runways.
Harbor Engineering: Used for soft foundation treatment, beach revetment, reinforcement of seaport wharves and breakwaters, drainage.
Green Engineering: Used for impervious and isolation in landfills.
