Product Description:

Instruction of Non-woven Geotextile for Railway Construction:

 

Geotextile is a non-woven product manufactured by combinining synthetic short yarns mechanically by using needling method. Non-woven geotextile has no woof and warp. Strength is achieved by combining yarns and applying thermal process. Geotextile felt is a permeable textile product which can be used with basic elements or with any material related with soil, running ground or geotechnic engineering.

 

Usuage Area of Non-woven Geotextile for Railway Construction:

 

Used in motorways, sport facilities, tunnels and underground facilities, art buildings, underground, agricultural areas, garden terraces, airports, mining fields, railways, solid waste storage areas, irrigation channels and reservoirs, shore protection and isolation areas; as a reinforcement against cracks between insulation layers; as a separator between waterproofing and thermal insulation layers; to protect insulation; to drain excess water; to prevent drainage pipes from plugging by wrapping them around; to avoid sinking and in many other applications.

 Advantages of Non-woven Geotextile for Railway Construction:

 

Thanks to thermal process, more strength and less elongation is achieved with the same weight.

Requires smaller storage area.

Can be manufactured up to a width of 6 meters, leading to less loss of material.

Both white and tinted varieties of ge0textile are manufactured from 100% pure yarn. No recycled material is used.

Products can be manufactured with surface weight ranging from 50 gr/m2 to 1000 gr/m2.

 

Application of Non-woven Geotextile for Railway Construction:

 

- in liquid bituminous insulation applications, it is used as a reinforcement  between layers and avoids cracks.

- it prevents cracks found on the surface from moving onto insulation surface.

- it protects bituminous membrane or geomembrane applications in foundations.

- it is used as a separator between waterproofing and thermal insulation layers.

- it is used as a separator between thermal insulation and protection layers.

- It is wrapped around drainage pipes in foundations and it is used as a filter layer in terrace gardens. 

- It is used in applications designed to withdraw pressure under road coatings.

Q:Acupuncture geotextile is divided into several kinds of how is it used?
Acupuncture geotextile is now divided into two types, according to the fiber form to points. Continuous fiber called filament acupuncture non-woven geotextile. A few centimeters of length fibers made of staple fibers for nonwoven geotextiles. Use is not used, mainly used in geotechnical engineering in the filter, isolation, drainage and so on.
Q:Geotextile CBR tear strength rate is how much
Geotextile CBR bursting strength is generally in accordance with the national standard GB / T-2017 "geosynthetics static top breaking test (CBR method)" according to the national standard GB / T-2017 standard requirements of geotextile CBR strong pre-tension 20N. According to the national standard GB / T-2017 standard requirements of geotextile CBR strong rate of (50 ± 5) mm / min.
Q:what are Smart Geotextiles?
These are textiles which use nano-technology to behave in certain ways under specific conditions. For example, a textile used for a tent can be white when the surrounding air is hot, but will turn black or dark when it's cold so it can absorb heat.
Q:Seepage geotextile and impervious geomembrane
It is generally believed that the individual geotextile does not have the anti-seepage effect, the main assessment index is the permeability coefficient, the general geotextile coefficient is higher than the ordinary soil, about 0.01-0.001 look, but the geotextile and rubber, Asphalt, plastic combination will form a water-impermeable composite, anti-seepage effect increased by 10 times, and asphalt, rubber combined into a waterproofing membrane such as sbs, etc., and plastic is generally polyethylene, polyvinyl chloride, eva (standard name is Geomembrane) is a combination of impermeable geomembrane or composite geomembrane, because the composite white geotextile outside the protective effect, so the project is also called impermeable geotextile. Therefore, the two are essentially not much difference, but the argument is different. Waterproof board is also called geomembrane, customary to> 0.8mm thick geomembrane called waterproof board, & lt; 0.8mm called geomembrane, it is based on high molecular polymer as raw material made of impermeable material , Divided into homogeneous waterproof board and composite waterproof board
Q:Geotextile exports Nordic need certification
Production standards geotextile, geomembrane, composite geomembrane.
Q:Filament spunbond nonwoven geotextile performance requirements for what is the basic item
Filament spunbond acupuncture non-woven geotextile is the implementation of the national standard GB / T-2008 standard. GB / T-2008 standard for filament spunbond acupuncture non-woven geotextile performance requirements of the basic items include: product vertical and horizontal nominal fracture strength (KN / m), vertical and horizontal nominal elongation at break (%) (KN), vertical and horizontal tearing strength (KN), mass per unit area deviation (%), width deviation (%), thickness (mm), vertical permeability coefficient (cm / s), equivalent pore size (O90 (95) / mm). Only the above indicators meet the corresponding GB / T-2008 standard requirements, be considered qualified filament spunbonded non-woven geotextile.
Q:Production of acupuncture carpets, geotextiles, warm flakes, paper blankets, air filter materials, the main raw material is what?
Fiber, like eating bread must be the same with the face
Q:What is the difference between polypropylene geotextile, polypropylene geotextile and polyester geotextile
Material is not the same
Q:What is the coefficient of friction for nonwoven geotextiles?
My company specializes in the production of geotechnical materials, treat people with sincerity to ensure your satisfaction.
Q:What is the standard width of geotextile?
Minimum width of 2 meters.
