Product Description

POLYPROPYLENE FILAMENT NEEDLE PUNCHED GEOTEXTILE

Product Introduction:
Using high-strength polypropylene slice as the main raw material, it is produced by non-woven technology and has the functions of isolation, reinforcement, protection, filtration, drainage, and buffering.
Product specifications: TDF100~1000, width 1m~6m., length according to user requirements.

Features:
The physical and mechanical properties are 2 to 3 times higher than that of conventional products. The proportion of products with the same gram weight is low; the acid and alkali resistance is excellent, the hot melt adhesion is good, and the wear resistance is strong. It is more suitable for CRTS/ slab ballastless track sliding layer system, which can reduce the interaction between the track system and the bridge surface.

Applications:
Polypropylene needle-punched non-woven geotextile is mainly used for the sliding layer between CRTS slab ballastless track and beam surface of passenger dedicated railway, and the isolation layer between CRTS slab ballastless track and friction. It can also be widely used Hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, environmental protection and other fields play the role of isolation, filtration, drainage, reinforcement, protection, etc.

Q:Are geotextiles commonly used in canal bank protection?: Yes, geotextiles are commonly used in canal bank protection.

Q:Can geotextiles be used in mine tailings dam construction?: Yes, geotextiles can be used in mine tailings dam construction. Geotextiles are commonly used as a geosynthetic material in various civil engineering applications, including dam construction. In the case of mine tailings dam construction, geotextiles can provide reinforcement, filtration, and drainage properties to enhance the stability and performance of the dam. They can help prevent soil erosion, control water flow, and improve the overall integrity of the structure.

Q:Woven geotextile is not considered a spinning geotextile: Woven geotextile is made of textile technology is a spinning geotextile.

Q:Do you want to use glue to connect the geotextile?: Shuo earth geotextile production of drainage board geotextile, Manager Li

Q:Can geotextiles be used in underground construction applications?: Yes, geotextiles can be used in underground construction applications. Geotextiles are commonly used in underground construction for various purposes such as soil stabilization, drainage, filtration, and erosion control. They help to improve the overall performance and longevity of underground structures by providing reinforcement and preventing the migration of fine particles.

Q:Do geotextiles require regular maintenance?: Yes, geotextiles generally require regular maintenance to ensure their effectiveness and longevity.
